First, product features and uses
Generally, PVC insulation and sheath compensation wire or cable has excellent moisture resistance, wear resistance and flame retardant characteristics: high temperature resistant fluoroplastic insulation and sheath compensation wire or cable adopts continuous extrusion process, and is more resistant to high temperature and cold. The superiority of acid and alkali resistant oil, non-flame retarding and anti-aging, the product quality is higher than the national standard GB/T4989-94 (equivalent to IEC584-3).
The intrinsic explosion-proof temperature measurement system uses a low-capacitance and low-inductance material structure for the compensation wire or cable. It has explosion-proof safety performance. It is suitable for explosion-proof thermocouple cold short and explosion-proof temperature measurement instrument in the environment with explosion hazard, forming intrinsically safe thermal power. Even temperature measurement system.
