A YFFB, YFFBJ series of temperature-resistant flat cable features:
YFFB, YFFBJ series temperature-resistant flat cable has the characteristics of cold resistance, softness, wear resistance, oil resistance, etc., and is suitable for AC rated voltage 06 1kV and below with special requirements such as cold resistance, oil resistance, etc., driving, trolleys, transmission machinery and other mobile electrical power transmission lines and control, lighting, communication lines, YFFB, YFFBJ series temperature-resistant flat cable has been widely used in metallurgy, electric power, shipbuilding, port and other industries.
2. Detailed introduction.
Structural characteristics of YFFB, YFFBJ series temperature-resistant flat cable.
The conductive core adopts a soft structure to ensure that the cable has good flexibility.
The insulation and protective layer materials are made of nitrile polymer to improve the flexible characteristics of the cable and the anti-corrosion and cold-resistant characteristics.
The insulated wire core is separated from each other, which provides convenience for laying and installation.
According to customer needs, wire ropes or other load-bearing elements (YFFBJ type) can be added on both sides of the cable core.
3. Product features of YFFB, YFFBJ series temperature-resistant flat cable.
Particularly soft, especially resistant to bending, moving back and forth, smooth and non-twisting. Indoor and outdoor, adapt to temperature, acid, alkali, oil and salt, can be protected. Strict material selection, advanced technology, reliable performance and long life.

6. Packaging, transportation and storage of cables
The cables can be packed in loops or in trays.
Cable transportation should ensure that the packaging is in good condition and strictly prevent mechanical damage.
Long-term storage should avoid low temperatures below -20 and high temperatures above 50.
VII Cable Order Representation:
When ordering, the cable is expressed by the model, rated voltage, number of cores x cross-section, standard number and required order length.
