Control Cable

Multicore control cable are mainly suitable for direct or AC 50~60Hz, rated voltage 600/1000v and below control, signal, protection and measurement lines. Multicore control cable are often used in electrical control systems and power distribution devices for fixed installation. Generally, the load in the control circuit is discontinuous and the current is not large, so the core wire section is small, usually below 10mm. The core of the control cable is mostly copper conductor. According to its core structure, it can be divided into three types: Type A (0.5~6mm, single solid core); Type B (0.5~6mm, seven single wires twisted); Type R (0.12~1.5mm², soft structure, Single wire diameter 0.15~0.2mm). According to the material of the insulating layer, it is divided into three categories: polyethylene, polyvinyl chloride and rubber. Among them, polyethylene has the best electrical properties and can also be applied to high-frequency lines. The insulating core of the control cable is mainly concentric stranded, and some control cables are twisted. The long-term allowable working temperature of the control cable core is 65℃.
