High temperatures can damage some types of cable. Therefore, it is very important to always be aware of the capacity of the high-temperature cable. In these cases, to increase safety, the conducting wires are usually formed by bare or tinned copper.
The main difference between the high-temperature heat-resistant cable and the common alternative is insulation, which is made with high-resistance tapes or silicone rubbers. For more details on this topic, follow this entire article here, in the Polyexcel blog!
What are the best options for high-temperature cable?
Before making the electrical connection of houses and establishments, it is necessary to know the conductor cables. This is because there are cases where they must resist high temperatures. To avoid accidents, it is indicated to use options that can resist temperatures above 350°C.
Thinking about meeting this need, the electric wires and cables sector created specific options for high temperatures. This alternative can be used in different locations, such as greenhouses and ovens, as well as being very useful on occasions that need the extreme temperature cable.
Heat-resistant wire and cable options are made with bare electrolytic copper, a material with excellent resistance. To ensure that the purchased product has quality, it is important to verify that the manufacture is made following the current technical standard in Brazil.
What are the main characteristics of this cable?
To not suffer damage to the structure, the high-temperature cable receives a layer of braided glass fiber, which resists up to 400°C. On the other hand, the element used to insulate the bare copper varies between resistance tapes and silicone rubbers.
The application of this material is very specific, so before buying it, it is worth verifying if it meets all the needs of your electrical connection. Below, check out the characteristics of the high-temperature cable.
- Insulation voltage;
- Flexibility in locations with zero temperature;
- Flame retardation and corrosion resistance;
- Capacity to work at a temperature up to 400°C.
Heat resistance will depend on the material used during the high-temperature wire insulation process. Silicone rubber, for example, has a resistance between 200°C to 300°C, while the high resistance tapes support up to 400°C. To make the right choice, analyze the needs of the connection.
What is the importance of a high-temperature cable?
A high-temperature cable makes all the difference in the installation. This is only possible because it provides safety during the operation of equipment and machines that need specific options for high temperatures. Neglecting this can cause serious accidents.
The high-temperature PP cable can provide even greater protection when it counts with textile braids with special varnish. Polymeric compounds are also very important electrical insulators for wires like these, as they count on several protective characteristics.
High-temperature cable and polymeric compound
The polymeric compounds work as electrical or thermal insulators for power and telecommunications wires and cables. For this, they go through a process in a lab, where they acquire some substances that give them specific characteristics for each type of electrical connection.
Among the flagships of Polyexcel, there is XLPE, an ethylene-based compound, wet reticulable and modified with silane vinyl. Popularly known as XPE and PEX, it is widely used in wires and cables of control, energy, and power for voltages up to 6 kV.
The capacity of a high-temperature cable can also be gained with HEPR, a thermoset polyethylene with the addition of elastomer. This characteristic reduces the artificial hardness of the cable installation temperature, facilitating the handling during the electrical process.
