1： Product features and uses
Generally, PVC insulated and sheathed compensating wires or cables have excellent moisture-proof, wear-resistant, and flame retardant properties; High temperature resistant fluoroplastic insulated and sheathed compensation conductor or cable adopts continuous extrusion process, which has more advantages of high temperature resistance, cold resistance, acid, alkali, oil and water resistance, non flame retardancy, aging resistance, etc. The product quality is higher than the provisions of the national standard GB/T4989-94 (equivalent to IEC584-3).
The compensating wires or cables used in the intrinsically safe explosion-proof temperature measurement system are made of low capacitance and low inductance materials, which have explosion-proof safety performance. They are suitable for connecting explosion-proof thermocouples with explosion-proof temperature measurement instruments in environments with explosion hazards, forming an intrinsically safe thermocouple temperature measurement system.
