What is High-Temperature Wire?

June 16, 2020

  High-temperature wire is made of high-temperature-resistant, high-strength type and processed through a special process. The main features are high-temperature resistance, insulation, fire retardant, corrosion resistance, aging resistance, weather resistance, high strength, high modulus, antistatic, smooth appearance, and so on. There are many types of high-temperature wires; commonly used fluoroplastic insulated high-temperature wires, silicone rubber insulated high-temperature wires, silicone rubber insulated braided wires, multi-core high-temperature cable wires, mineral insulated refractory cables, high-temperature electronic wires, Teflon wires, aircraft wires, Nylon sheathed wire, Teflon high voltage wire, silicone rubber high voltage wire and mica high-temperature wire. Its product characteristics are a rated voltage of 600V, which can be used at an operating temperature of -65 to + 200 ° C. Its conductor is a solid core or a twisted silver-plated copper wire, which is insulated from FEP Teflon and its colors are red / yellow / blue / white / black / yellow-green / brown etc.

   

There are generally two kinds of materials for high-temperature wires. One is: silicone rubber, which has better softness; the other is: Teflon material (that is, polytetrafluoroethylene), Teflon material is relatively hard.

 

Silicone rubber materials can be applied to the installation and connection of electrical circuits with an AC rated voltage of 500 volts or below. They are widely used in electric heating appliances, paint rooms, lighting equipment, and household appliances.

   

Teflon has a series of excellent performance properties: high temperature resistance with long-term use temperature of 200 ~ 260 degrees, low temperature resistance-still soft at -100 degrees; corrosion resistance-resistant to aqua regia and all organic solvents; good aging life; high lubrication-with the smallest friction coefficient (0.04) in plastics; non-sticky-with the smallest surface tension in solid materials without sticking any substance; non-toxic-with physiological inertia; The most important of sizes for Teflon are FEP High Temp Wire and PFA Insulated Wire.

 

Teflon is the engineering plastic material with the highest temperature resistance (280 ° C), the highest electrical resistance (45KV / mm), strong acid-resistance, strong alkali resistance, the most resistant to stickiness, the most slippery, and abrasion resistance in plastics; electronics, chemicals, valves, and other parts. Teflon hoses are widely used in the chemical, instrument, electric heating, and machinery industries. Among them, insulating sleeves are widely used in aerospace, automotive, medical, electronic transformer, and communication technology industries due to high temperature and voltage resistance (300V).
