Retardant twisted flexible cord for connection (ZR-RVS series) products suitable for AC rated voltage U0 / U is 300 / 300V and below appliances, instrumentation and power lighting. Used for fire alarm systems, also known as "fire line." Flat-type non-sheathed cord (RVB red and black wire series) products suitable for AC rated voltage U0 / U is 300 / 300V and below appliances, instrumentation and power lighting. Because red insulated side, black side, also known as "red-black line." Insulation: protection current in a conductor by normal GSM frequency computer cables, requires a certain amount of electrical insulation properties and mechanical and physical properties, and insulation resistance, engage in tensile strength, elongation at break to meet the standards, but non-standard cables in general the use of recycled PVC materials extruded insulation, electrical and mechanical and physical properties are mainly the computer cable prices, to use a security risk. Cable core: the core 2 or more cores stranded structure of the computer cable to be used to increase the flexibility of the cable, the cable core stranding process can be used to increase the insulation wrapped with electrical performance and easy construction of sheath removal, may be Talc way too easy to use the jacket stripper. Computer cable prices, computer cables, provided by the Anhui Anhui Global Global instrument cable Limited.
