Electrical wires work quietly behind walls, ceilings, machines, and electrical systems. However, high temperatures can put these cables to the test. In addition to damaging the insulation, excessive heat speeds up aging and reduces the efficiency of an electrical installation.
That is why it is important to buy products from experienced Electrical Wire manufacturers, especially when the installation area is exposed to heat. However, what makes these electrical wires ready for harsh conditions?
Why Is Temperature Important for Electrical Wires?
Heat is one of the main elements that influence the wire during usage. The presence of current leads to the generation of heat. Therefore, if the temperature increases, the thermal load also rises.
If the wire has poor-quality insulation, it will lose its properties faster because of becoming brittle or softer. As a consequence, the probability of leakage or electrical breakdown increases. That is why the thermal performance of both the conductor and the insulation is taken into account during manufacturing.
What Is the Function of Insulation?
It is possible to compare the role of insulation with the jacket that covers the electrical wire. It not only covers the wire but also protects it from unwanted interaction with other materials.
Depending on the purpose of the application, Hilite’s India use insulation materials that are appropriate for specific conditions of usage and the required level of fire resistance. For example, insulation made of PVC can be adapted to specific conditions.
In case of severe environments, specialized insulation formulations can increase the level of heat and flame resistance of wires. It is especially useful for applications in industrial zones, on roofs, in attics and other places with elevated temperature levels.
How Do Manufacturers Increase Thermal Resistant of Cables?
There are several steps during manufacturing in which the thermal performance of a cable is improved.
- First of all, the proper choice of materials and manufacturing process is required.
- Then, proper conductors and insulation have to be selected.
- The final product demonstrates good characteristics in regular operations, rather than during the ideal tests.
A controlled manufacturing process is essential because consistency in batches can be critical when the cables are applied in large electrical systems.
Where Are Heat-Resistant Wires Appropriate?
Heat-resistant electrical wires can be especially helpful in cases when the environmental temperature is higher than the norm. Some examples of applications of heat-resistant electrical wires are:
- Solar roof installations
- Industries
- The place is near electrical devices
- Attics and enclosed spaces
- Metal sheets roofs and terraces
- Electrical installations exposed to heat
The proper wire has to be chosen taking into account the environment of installation, the load of an electrical installation, standards and other peculiarities of the project.
Why Do You Have to Pay Attention to the Manufacturer?
Two cables can be absolutely similar in their appearance but differ greatly by performance characteristics. The reason for that difference can be found in the quality of conductors, insulation, manufacturing process, testing and other factors.
Thus, established Electrical wire companies may offer not just a product, but also consistency, specifications and solutions for operating in different conditions.
Hilite’s India produces various wires for residential and industrial use, including special HR-FR wires for high heat and flame resistance.
Conclusion
Temperature is an important aspect that is often forgotten when choosing electrical wires, yet it can affect performance greatly. One should not choose a wire based solely on its diameter or cost, but also consider the environment where it will be used.
