High temperature cable

High-temperature cable is a cable whose conductor material is multi-strand soft copper conductor. Heat resistant and high temperature wires and cables are generally determined by two requirements. The first is that the ambient temperature of wires and cables is high, and the cables can normally transmit signals or electric energy under high temperature for a long time; The other is the power transmission cable, which is mainly aimed at increasing the interception capacity. Most wires and cables are insulated with plastic and rubber. These materials are conventional engineering materials with rich sources, which can meet the requirements of mass production and relatively low cost. However, for some special industries, such as petrochemical, steel, aerospace, shipbuilding, military, pharmaceutical, food, plastic machinery, boilers and other industries related to heat and high temperature, wires and cables that can withstand a certain high temperature are required. Ordinary wires and cables are obviously not used. High-temperature resistant wires and cables are required to ensure the safe operation of their power and signal.  

Structural parameters of high-temperature cable

Conductor material: multi-strand soft copper conductor; Insulation material: fluoroplastic insulation, temperature range - 60-260 ℃; Filling material: glass fiber; Sheath material: fluoroplastic sheath, temperature range - 60-260 ℃.

Service characteristics of high-temperature cable

1. AC rated voltage: U0/U 450/750KV. 2. Maximum working temperature: the insulation temperature of polytetrafluoroethylene propylene (F46) shall not exceed 200 ℃, and the insulation temperature of soluble polytetrafluoroethylene (PFA) shall not exceed 260 ℃. 3. Minimum ambient temperature: PVC sheath: fixed laying - 40 ℃, non-fixed laying - 15 ℃, fluoroplastics and.

High temperature cable market demand

With the rapid development of China's economy, the demand for high-temperature cables in special industries has shown a rapid growth step by step. The heat-resistant and high-temperature cables grow at a rate of 20% every year. As an important part of special cables, high-temperature cables have extremely strong vitality, and supply exceeds demand. China imports about 2 billion yuan from abroad every year for domestic construction.
