Ⅰ. Characteristics and application

The structure of product is sealed insulation and sheath, which is better than wrapped braiding one. PVC insulated and sheathed extension wire for general use has good features of moisture-proof, resistance to wearing and fire. Heat-resistance extension wire with fluoroplastic insulation and sheath is manufactured by new process of continuous extrusion. Its excellent properties include resistance to high temperature, low temperature, acid, soda, oil, wearing, aging, flame and water. The quality of the products is better than the requirement of national standard GB/T4989-94 (equivalent to international standard IEC584-3). Thermocouple allowance can reach A class precision degree.

The role of extension wire used in thermocouple is to stretch the clamp of thermocouple and connect with instrument to form a temperature testing system.

Extension wire used in thermocouple for intrinsically safe explosion-proof temperature testing system has a structure with low capacitance and inductance. Explosion-proof is its characteristics besides those in extension wire used in thermocouple.

The product is suitable for using in dangerous environment and places where high explosion-proof safety condition is required. The cold clamp of explosion-proof thermocouple is extended to connect with explosion-proof temperature testing system instrument, which forms intrinsically safe temperature testing system.
