Compensative wire and compensative cable
Compensative cable and wire match thermocouple, and is suitable for temperature measurement and control in the field of electrical.metallurgical,petroleum.chemical and scientific research.
Our company can manufacture in accordance with GB/T4989-1994.
The compensative wire can be divided into extended type and compensative type, extended compensative wire is marked "X" after the thermocouple index, and the compensative cable should mark "C" after the thermocouple index.

Main technical explanation
(1) PVC is used as the main material of insulation and sheath of compensative wire, and poly tetrachlorethylene is used as the main material of insulation and sheath of heat resistant compensative wire.
(2) The common products includes cable at the highest temperature of 70 ℃and 100℃. The heat resistant products can work below the temperature of 200℃ and 260℃.
(3) The minimum bend radius
The armoured cable is not less than 12 times of outer diameter of the cable
PVC insulated and sheathed unarmoured cable is not less than 6 times of cable's outer diameter.
Fluoroplastics insulated and sheathed cable is not less than 6 times of cable's outer diameter.
