Compensation wire and compensation cable for thermocouple

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.

Third, the use of characteristics

The highest working temperature of the conductor: heat-resistant grade: polyperfluoroethylene propylene (F46) 200°C; soluble PTFE 260°C; silicone rubber 180°C; ordinary grade: polyvinyl chloride 70°C and 105°C, cross-linked poly Ethylene 90°C; low smoke zero halogen flame retardant polyolefin 70°C, crosslinked type 90°C and 125°C.

2, the minimum ambient temperature: PVC sheath: fixed laying -40°C, non-fixed laying -15°C; fluoroplastic insulation and sheath: fixed laying -60°C, non-fixed laying -20°C.

3, the allowable bending radius of the cable: the minimum of the outer diameter of the non-armored cable is 6 times; the minimum of the copper tape shielded or steel tape armored cable is 12 times the outer diameter of the cable; the minimum of the fluoroplastic insulation and sheath is the outer diameter of the cable 10 Times.
