The Ultimate FAQ Guide to NEMA Outdoor Telecom Enclosures

Why are outdoor telecom enclosures useful?

Outdoor telecom enclosures house important telecommunication equipment and accessories, both for residential applications and street-type applications.

This is necessary for many sectors, such as residential, commercial, and industrial.

Outdoor telecom cabinet/enclosure

Many businesses and services are built around telecommunications, making outdoor telecom enclosures a must in their environment and functioning.

More specifically, outdoor telecom enclosures are used in data centers, office environments, server rooms, internet server providers, mobile operators, and various broadband networks, which are long-distance telecom cables connecting to the end-user.

Outdoor telecom cabinets protect the cables and equipment that processes and reroutes information that we communicate through the internet, television, and other such applications.

These enclosures have organizing racks, thermal management systems, and much more.

What is a fiber cabinet?

Fiber cabinets are basically a subtype of outdoor telecom enclosures, housing optical fibers, and cables for different service providers, hubs, power line networking, high-speed internet, ethernet, cable TV, and more.

These cabinets allow for distribution of networks to different points, such as routers, buildings, homes, and further telecom cabinets.

 Fiber cabinet with fibers and copper

Fiber cabinets have many cables and can have 2 parts: fiber-optics and copper.

Both are used to carry signals, but fibers are often faster, so they are used more nowadays.

How are cables organized in outdoor telecom enclosures?

يتم تنظيم الكابلات باستخدام المشابك والرفوف.

غالبًا ما تعمل المشابك والأقواس على تثبيت الكابلات مضغوطة في أحد ألواح العلبة، مما يحافظ على تنظيم الأشياء.

الرفوف وتصاميمها يمكن أن تكون أكثر تنوعًا، حيث إنها غالبًا ما تعيد توجيه الكابلات وتوصيلها إلى علب أخرى أو إلى بعضها البعض.

Adjustable racks are very common in outdoor telecom enclosures, allowing the personnel to place levels of the rack at different heights.

Racks have various openings that have their purposes. For example, racks can have euro, rectangular, square, T-shaped openings.

أشكال مختلفة من فتحات الرفوف

Large rectangular openings are usually used to lead cables to an adjacent enclosure or a different compartment of the same enclosure.

يتم استخدام الفتحات على شكل حرف T لربطات الكابلات ذات الخطاف والحلقة.

الثقوب الأوروبية مخصصة لمديري الكابلات، في حين أن الثقوب المربعة مخصصة للمثبتات الإضافية للرفوف.

There are also many different fiber organizers, pass-through panels, troughs, partitions, hooks, and rings that all keep cables in check inside outdoor telecom enclosures.

Another additional feature that helps organize and reroute cables in outdoor telecom cabinets is a cable boot.

Cable boots are similar to pass-through panels in the sense that they allow cable through and consist of special gaskets.

  Cable boots

However, pass-through panels are typically in a rectangular or square shape, while cable boots are cylindrical or conical, allowing one cable or a specific bundle of cables through.

So, in a way, cable boots are more selective that panels.

What are thermal management systems that are important for telecom cabinets?

Electrical equipment, such as cables and batteries, produce heat as they work.

Outdoor telecom enclosures have a lot of this electrical equipment, so they need reliable thermal management systems and solutions to keep everything safe and running.

Some good thermal management solutions that you can explore and request include natural convection, phase change materials, heat exchangers, and double-walled enclosure design.

Natural convection includes vents, fans, and air filters.

They work well with low-power enclosures, so they are not the best for telecom cabinets.

Either way, natural convection can be an added thermal management solution to the main one, which would be great for outdoor enclosures since this method eliminates solar heating.

Phase Change Materials are placed inside tubes and they keep the temperature inside the enclosure roughly constant, adjusting to daytime and nighttime changes.

 How PCM works

These work well with fans, and are used to cool down batteries.

Heat exchangers consist of two parts, the bottom part that is located in the battery part and the top part that is located in the electronics compartment, which is cooled down by an air-conditioning system.

Heat exchanger in an enclosure

Heat pipes transfer heat from the batteries into the electronic compartment, where cold air from the air conditioner forms a hybrid refrigerator system of the heat exchanger.

Double-walled cabinet design incorporates fans as well for efficient ventilation.

Fans on the top panel give the best cooling and energy minimization results.

 Double-wall enclosure design

How are outdoor telecom enclosures different in design from regular enclosures?

Besides organizing racks and thermal management systems, a big difference is that outdoor telecom enclosures sometimes have 2 or more compartments for various things.

The typical breakdown is the electrical equipment compartment on the top and the battery compartment on the bottom.

The batteries help the electrical components run since they process and forward a lot of information, so they need a lot of power to do so.

There also could be a battery tray for smaller enclosures.

Telecom enclosures also have ground bars, usually copper ones, for safety purposes, and load centers.

Load centers are basically distribution ports and circuit controls.

Outdoor telecom cabinet with multiple compartments

Finally, outdoor telecom cabinets also frequently have quad receptacles, which help further reroute and connect different cables.

ما هي تصاميم العلبة التي يمكنني الاختيار من بينها؟

Designs for outdoor telecom enclosures do not differ from other enclosures we make.

More specifically, we offer free-standing enclosures, floor-mounted, wall-mounted enclosures, pole-mounted enclosures, recessed enclosures, and – of course – custom enclosures.

حاويات قائمة بذاتها تعتبر مثالية للوحدات الكهربائية الكبيرة التي تكون ثقيلة جدًا بحيث لا يمكن تثبيتها على الحائط أو العمود. يمكن أن تكون بأي ارتفاع أو عرض.

كما أنها محمولة أيضًا.

       حاوية قائمة بذاتها

الحاويات المثبتة على الأرض تشبه إلى حد كبير الحاويات المستقلة، حيث يتم تثبيت الحاويات المثبتة على الأرض فقط - وبالتالي، فهي غير قابلة للنقل.

حاويات مثبتة على الحائط use mounting brackets, screws, and pads.

They are perfect for small devices, and thus are cost-effective.

 حاوية مثبتة على الحائط

Pole-mounted enclosures are not too different from wall-mounted ones.

They also use mounting brackets, but they are ring-shaped, placed around the pole.

These, and wall-mounted enclosures are very popular with outdoor telecom cabinets.

Pole-mounted outdoor telecom enclosure

صناديق كهربائية مدمجة يتم تثبيتها في حفرة في الحائط أو الأرضية.

They can be of any design, but are recessed into something, so only the door is visible.

Recessed enclosure

Such telecom enclosures can be recessed into the ground or into the outside wall of a building, which works very well with commercial and residential telecom enclosures.

بالطبع، لدينا أيضا مرفقات مخصصة, which will suit your special requirements.

بالإضافة إلى ذلك، فإننا نقدم خيارات مختلفة للأبواب، بما في ذلك الأبواب الفردية والمزدوجة والمتعددة.

تعتبر الأبواب الفردية مثالية للوحدات الكهربائية الأصغر والأقل تعقيدًا، في حين تُستخدم الأبواب المزدوجة للوحدات الكبيرة والمعقدة.

تُستخدم الأبواب المتعددة للتطبيقات الصناعية الضخمة أو لزيادة الأمان.

What general accessories can I add to the outdoor telecom enclosure?

You can also request vents, windows, hinged doors, locks, and cable management systems.

فتحات التهويةبالإضافة إلى المراوح الإشعاعية، توفر مسارًا للحرارة للهروب من خلاله، مما يؤدي إلى تبريد المكونات الكهربائية للغلاف.

وهذا يطيل عمرهم ويقلل من احتمالية حدوث أعطال.

Radiating fan in an enclosure

These also stabilize air pressure inside the enclosure, preventing condensation which can damage the electrical components of the enclosure.

Plus, the vents can be further upgraded to air conditioners and heat exchangers.

وإذا حدث خطأ ما، فإن النافذة تساعدك على رؤية ما يحدث على الفور.

بالإضافة إلى ذلك، تساعد النوافذ بالأشعة تحت الحمراء في حماية الموظفين من قوس كهربائي الحوادث.

These are rare on outdoor telecom cabinets because maintenance does not happen that often, and windows can compromise the protection of the enclosure.

 حاوية بها نافذة

أبواب مفصلية التحكم في كيفية ومدى فتح الباب أو غطاء العلبة.

This also includes a variety of handles that you can request as well.

أقفال add a layer of security to your outdoor telecom enclosure, making sure no one tampers with it or accidentally accesses the telecom cabinet.

تشتمل الميزة الصغيرة الأخرى على جيوب للملفات.

تُستخدم جيوب الملفات لتخزين الملفات مثل أدلة التشغيل، وسجلات المناوبات، وكتيبات المعلومات، وأي شيء آخر مهم يتعلق بالمكونات الكهربائية داخل العلبة.

For outdoor telecom cabinets, these are better placed on the inner door of the enclosure since otherwise the files may be damaged or tampered with.

Cable management systems such as cable entry frames and clamps serve to keep wires organized and make them easier to install and maintain.

تعمل إطارات دخول الكابلات على إعادة توجيه الكابلات وتوجيهها داخل وخارج العلبة إلى مصدر خارجي.

وفي الوقت نفسه، تعمل مشابك الكابلات على تثبيت الكابلات في مكانها.

يمكن أن يكون هناك أيضًا رفوف وحزم مختلفة إذا كان هناك الكثير من الكابلات.

Smaller accessories that you can request for outdoor telecom enclosures include solar shields, rain caps, lifting eyes, and even door alarms.

Solar shields are basically another layer on top of an enclosure that reflects solar radiation, controlling the inner temperature of the enclosure to prolong the life of its electrical components.

This, like a vent, is especially important for outdoor telecom enclosures.

   Solar shield (the top plate)

Rain caps are the top parts of an enclosure.

They can be flat, but protruding forth more than the enclosure, or they can be tilted like a roof.

They help divert streams of rain off of the enclosure so the rest of it gets less exposure to the rain.

This prolongs the life of your enclosure.

  Rain cap

Lifting eyes aid installation.

They are little hooks at the corners of an enclosure that you can use to lift it up for transportation of mounting.

This is especially useful if an enclosure is very heavy and the only way to transport it is by lifting it up.

Lifting eyes

Door alarms are another security measure besides locks.

Outdoor telecom cabinets may be subject to vandalism and tampering, so a door alarm with making noise if someone unauthorized opens the enclosure.

What materials are outdoor telecom enclosures made from?

The materials used for our outdoor telecom enclosures aren’t different from materials used for other types of enclosures.

يمكن أن تكون مصنوعة من الفولاذ الكربوني, فولاذ مجلفن، و الفولاذ المقاوم للصدأ - عادة من الدرجات 304 أو 316L.

ضع في اعتبارك أن لكل منها صفات معينة.

عادةً ما يكون الفولاذ الكربوني أكثر باهتة من الفولاذ المقاوم للصدأ.

كما أنها مغناطيسية وأكثر قابلية للطرق حيث أنها تحتوي فقط على الحديد والكربون.

يعتبر هذا الفولاذ أيضًا عرضة للتآكل.

يتم إنشاء الفولاذ المقاوم للصدأ عن طريق إضافة الكروم والنيكل والموليبدينوم إلى سبيكة الحديد والكربون.

الفولاذ المقاوم للصدأ مقابل الفولاذ المجلفن

تختلف الدرجات 304 و 316 في محتوى جميع المواد المضافة.

الدرجة 316 أقوى قليلاً ومقاومة للمياه المالحة والحمضية.

تتمتع الدرجة 316L بمحتوى كربون أقل، مما يجعلها أقوى قليلاً.

الفولاذ المجلفن مطلي بطبقة من الزنك مما يمنحه خصائص مقاومة للتآكل.

في حين أننا نقدم علب من الفولاذ المجلفن, this metal is vulnerable to salt water.

يرجى ملاحظة أن الفولاذ المجلفن أكثر تكلفة وأثقل وزنًا من الفولاذ المقاوم للصدأ.

بالإضافة إلى ذلك، يمكننا تضمين النوافذ المصنوعة من البولي كربونات، وABS، والبلاستيك المقوى بالزجاج مثل الألياف الزجاجية.

يعتبر البولي كربونات أكثر مقاومة للتآكل، في حين أن مادة ABS أرخص.

الألياف الزجاجية is very strong, can dissipate heat, and insulates electricity, lowering the effect of interference and the possibility of shock.

It is made from glass fibers placed in plastic.

How protected can outdoor telecom enclosures be?

Outdoor telecom enclosures need to be protected against any outside hazards, such as dust, rain, snow, UV radiation, shock, impact, and even vandalism.

But besides that, enclosures need to have such a design that even inside hazards do not tamper with your electrical components.

These internal hazards include condensation, fumes, chemicals, and even air pressure.

To combat these, we provide any level of protection that your outdoor telecom enclosures need, both according to IP standards as well as NEMA ones.

IP enclosures use the رمز IP، والذي يتكون من رقمين - أحدهما يتوافق مع الحماية ضد دخول المواد الصلبة، في حين أن الآخر ضد دخول السوائل.

الحد الأقصى للحماية IP الذي يمكن أن يتمتع به أي حاوية هو IP69K، وهو مقاوم تمامًا للغبار ويمكن غمره تحت الماء لفترة طويلة ورشه بالماء الساخن المضغوط.

نحن نقدم المرفقات حتى IP66، مما يعني أنه مقاوم للغبار ويمكن رشه بنفثات ماء مضغوطة، بالإضافة إلى غمره تحت الماء لمدة 30 دقيقة.

أما بالنسبة ل نيما standards, we offer any type, starting from 1 and up to 13, including subtypes, such as 3R.

Our حاويات NEMA محمية ضد العوامل الجوية والتآكل وتسرب الزيت وأكثر من ذلك بكثير.

 مقارنة بين تصنيفات NEMA وIP

Outdoor telecom cabinets are often rated with IP65 and up, or 4/4X and up.

What warnings can be posted on outdoor telecom cabinets?

There are 3-4 main signs that are common on outdoor telecom enclosures, but there are also 3 different levels of warning that are used in conjunction with symbols.

The most common symbol on telecom enclosures is the “shock” symbol, which is a yellow triangle with a lightning bolt in the middle.

Shock symbol

This symbol communicates to personnel that maintenance should be done carefully, discharging static electricity from tools and avoiding shorting connections.

It also means that any flame nearby will be dangerous, as it may produce an explosion, or an arc flash.

Sometimes, a skull is added to the symbol as well, warning people not to tamper with the enclosure.

Another symbol that can be used on telecom cabinets is the VRLA battery symbol.

It is also a yellow triangle with a leaking cell on it.

  VRLA battery symbol

This symbol communicated to personnel that there are VRLA batteries in the enclosure, which contain sulfuric acid.

In contact with skin, it causes severe burns and irritation.

The third common symbol that outdoor telecom cabinets have is the “do not smoke” symbol – a crossed out cigarette.

“Do not smoke” symbol

It tells anyone nearby not to smoke because the batteries inside the enclosure may emit explosive gases.

The three levels of warning are as follows: danger, warning, and caution.

“Danger” means that anyone who does not follow directions may be killed or seriously injured.

“Warning” means the same thing as “danger”, but to a lesser degree.

Finally, “Caution” means that anyone tampering with the enclosure may be injured or may damage the equipment inside.

What paint is better to use for coating outdoor telecom cabinets?

Our enclosures are well-protected, but the right coating can add its protection as well.

يمكنك اختيار طبقات الطلاء المينا أو المسحوق بأي لون.

طلاء المينا يتميز بلمسة نهائية لامعة ومقاوم لظروف الطقس المختلفة.

تُستخدم عادةً دهانات المينا المحددة مثل مينا الإيبوكسي ومينا البولي يوريثين للأسوار الصناعية لأنها مقاومة للتآكل.

مسحوق الطلاء is deposited with the electrostatic force and is quicker and easier than enamel.

كما أنه أكثر مرونة في المظهر، مما يتيح لك خيار التشطيبات اللامعة وغير اللامعة.
