Difference between high temperature cable and ordinary cable

What is the difference between high temperature cable and ordinary cable? High temperature cables are mainly suitable for connecting cables for lighting lamps of various household appliances and temperature sensing of electronic equipment.

Difference 1: insulation performance. Different from ordinary cables, high-temperature electricity with high temperature resistance has strong insulation performance. In this way, in some factories or laboratories with high requirements, high-temperature cables can avoid the problem of short circuit or circuit influence and achieve better use effect.

Difference 2: aging resistance. One of the great advantages of high-temperature cables is that they are aging resistant and durable. Such high-temperature cables can be used for a long time and can help us solve many cost problems. However, ordinary cables have a fixed service life and need to be replaced in time after use for a certain time, so the replacement frequency is relatively high, which affects the efficiency and increases the cost.

Difference 3: flame retardancy. Because the material of high-temperature electricity is made of special materials, its flame retardancy is particularly good. When there is a short circuit or high-temperature fire, it will not affect other circuits in series at once to increase the risk, but carry out flame retardancy effectively, with higher safety performance.

Difference 4: different materials. As the name suggests, other main materials of high-temperature cables are also high-temperature resistant materials, so that they can be used in a high-temperature environment without affecting their main effects. High temperature cables are generally divided into fluoroplastic insulated high-temperature cables with high silicon stabilized rubber insulation.

Cable, silicone rubber insulated braided cable, multi-core high-temperature cable, while ordinary electricity may be made of common materials such as aluminum electricity or copper electricity.

Understanding High-Temperature Wire

High-temperature wire is often defined as a wire with a temperature rating of 125°C or higher, although high-temperature can also refer to temperature ratings as low as 90°C. High-temperature cables can either be single-conductor or multiconductor. These products commonly consist of a conductor (usually annealed, tinned copper, copper-plated or nickel-coated copper) and insulation. High-temperature wires may also have an additional jacket consisting of a fiberglass braid or K-fiber material.

Two key components to ensure high-temperature wires are suitable for the application are the wire’s temperature rating and ampacity. Temperature ratings can be defined as the maximum continuous temperature that a wire can withstand during its lifetime. If a cable’s temperature rating is not suitable for the environment and ambient temperature, the expected lifespan of the cable could be affected.

The ampacity is the maximum current an insulated conductor can safely carry without exceeding its insulation and jacket temperature limitations. If the cable is undersized, the heat produced by circuit load may exceed the cable’s temperature rating and the cable may be compromised.
