1、YFFB-FJL flat flexible cable with steel wire tensile load bearing on both sides Overview:
The load-bearing flat flexible cable has the characteristics of cold resistance, softness, wear resistance and oil resistance, which is suitable for AC rated voltage0.6/1KVAnd the following power transmission lines and control, lighting, communication lines for driving, trolley, transmission machinery and other mobile electrical appliances with special requirements of cold resistance and oil prevention. This product has been widely used in metallurgy, tc thermocouple power, ship, port and other industries.The conductor core adopts soft structure to ensure the good flexibility of the cable.
The insulation and protective pt100 RTD layer materials are made of butadiene polymer, which can improve the flexibility, corrosion resistance and cold resistance of the cable.
The color separation of insulated core provides convenience for laying and Assembly Thermocouple installation.
Steel wire rope or other load-bearing elements can be added on both sides of the cable core according to the needs of customers(YVFB-Gtype)。
2、 Features:
Especially soft, especially resistant to bending, Boiler wear-resistant thermocouple moving back and forth, stable and not twisted.
Indoor and outdoor, suitable for temperature, acid, alkali, oil and salt, can be protected.
Strict material selection, advanced technology, reliable performance, long life.
