K-type compensation wires are generally insulated and sheathed with polyvinyl chloride. The compensation wires or cables have excellent moisture-proof, wear-resistant and flame-retardant properties; the high-temperature resistant fluoroplastic insulated and sheathed compensation wires or cables adopt continuous extrusion process, which is more resistant High temperature, cold resistance, acid and alkali oil and water resistance, non-flammability, anti-aging and other advantages, the product quality is higher than the national standard GB/T4989-94 (equivalent to IEC584-3).

K-type compensation wire is intrinsically safe. The compensation wire or cable used in the explosion-proof temperature measurement system adopts low capacitance and low inductance material structure and has explosion-proof safety performance. It is suitable for the connection of explosion-proof thermocouple cold short and explosion-proof temperature measuring instrument in an environment with explosion danger. Form an intrinsically safe thermocouple temperature measurement system.

K-type compensation wire use characteristics

1. The highest working temperature of the conductor: heat-resistant grade: fluorinated ethylene propylene (F46) 200℃

Soluble polytetrafluoroethylene 260℃

Silicone rubber 180℃

Ordinary grade: polyvinyl chloride at 70°C and 105°C, cross-linked polyethylene at 90°C

Low-smoke halogen-free flame-retardant polyolefin at 70°C, cross-linked at 90°C and 125°C

2. Low ambient temperature: PVC sheath: -40℃ for fixed laying, -15℃ for non-fixed laying

Fluoroplastic insulation and sheath: fixed laying -60℃, non-fixed laying -20℃

3. Allowable bending radius of cable: The minimum of non-armoured cable is 6 times the outer diameter

Copper tape shielded or steel tape armored point cable is 12 times the outer diameter of the cable

Fluoroplastic insulation and sheath are 10 times the outer diameter of the cable
