How do you Regulate Temperature in Roadside Electrical Cabinet?

Roadside cabinet heater

Temperature regulation is critical for the optimum operation of your roadside electrical cabinet.

High-temperature results in the melting of the electrical components causing it to malfunction

Low temperature makes certain components within a roadside electrical cabinet such as plastic lose their flexibility.

This affects the tightening and sealing of the glands.

The main ways of regulating the temperature of your roadside electrical cabinet include:

Use of Heaters

The use of heaters is for increasing the temperature levels of your roadside electrical cabinet.

Heaters are essential in areas where there are low temperatures

The main types of heaters available are; Explosion-proof heaters which use the traditional way to heat your roadside electrical cabinet.

That is, cold air circulates the heater’s body, which raises its temperature.

As the air warms up, it becomes light causing it to rise and circulate within the roadside electrical cabinet.

The process continues to make sure the roadside electrical cabinet maintains the right temperature for its use.

These are the only heaters that you can comfortably use in a hazardous environment.

The other type of heater is the Fan heaters which are a simpler form of heating your roadside electrical equipment.

It involves the passing of electrical current through the heating element, which creates heat.

Air flowing in roadside electrical cabinet

As this happens, air from within the enclosure flows into the heating element using the fan.

It is this heat that warms up the air which circulates within the enclosure, thereby raising its temperature.

You also have PTC (Positive temperature coefficient) heaters whose use is mainly through conductive materials.

The working of this heater is that it allows for current to pass through when the enclosure gets cold.

However, when the temperature starts increasing, the material begins inhibiting the current flow.

That is temperature increase results in an increase in the increase of the electrical resistance of the material.

This has the effect of limiting the current flow.

It is an effective method since it does not cause overheating of your roadside electrical cabinet.

Use of Ventilation

Ventilation in electrical enclosure

Ventilation is a natural way of regulating the temperature of your roadside electrical cabinet.

The main aim here is to cool the enclosure.

There are two types of ventilation that you can use.

That is natural convection ventilation which utilizes heat transfer from the warmer regions to colder regions within your roadside electrical cabinet.

This only takes place when the outside environment of your roadside electrical cabinet is colder than the inside.

This way, heat radiates from the enclosure through the walls to the outside environment.

As this happens, the internal temperature reduces to a level that is equal to that of the external environment.

Natural convection ventilation is a less costly and straightforward option for your roadside electrical cabinet.

However, it is less effective since it is dependent on the temperature of the external environment.

This implies if the external temperature is higher, the roadside electrical cabinet will not cool.

If this happens, there is a compromise on the efficiency of the performance of your roadside electrical cabinet.

There is also forced convection ventilation uses a fan or blower to force warm air out of your roadside electrical cabinet.

It is important to note that whichever blower or fan you use, it should include a filter.

Remember, air flowing from the outside to the inside may have contaminants such as dust and dirt.

When these contaminants get in contact with the electrical components of your roadside electrical cabinet, malfunctioning occurs.

A filter is, therefore, a vital component in filtering the air flowing into the roadside electrical cabinet.

This method is relatively affordable and easy to install.

You can also control the volume of air flowing into the enclosure by adjusting the speed of the fan or blower.

However, it requires regular maintenance to remove the contaminants present in the fan or blower.

If this does not happen, dirt will accumulate on the blower or fan, which may hinder its proper functioning.

This causes dirt to enter into the electrical components

Insulation

 Insulated roadside electrical enclosure

Insulation is vital in temperature regulation since it prevents the loss of heat from your roadside electrical enclosure.

The main types of insulation materials are; polyurethane and polyisocyanurate foam.

Polyisocyanurate foam is a combination of polyol and isocyanurate using a catalyst.

The resulting polyisocyanurate is a cellular thermoset.

It is an ideal material due to the features of the individual components which have closed cells.

These cells form a fire-retardant structure.

The generally inert, highly stable material offers the highest weight to strength ratio and a superior thermal insulating material.

Polyurethane is a rigid and offers high-performance material for the insulating roadside electrical cabinet.

The high cross-linked property of the polyurethane that is of low density.

The low thermal conductivity of the blowing agents present in the polyurethane is what makes them the best insulating material.
