Power cable through a certain load current, will heat, with the increase of load current, the higher the cable surface temperature, if not handled in time, the consequences can be imagined. For example: polyvinyl chloride (PVC) cable, the core temperature is considered as the upper limit of 70 degrees, and the surface temperature will be 5 to 10 degrees lower. Therefore, the cable surface temperature below 60 degrees is basically safe, from the power supply maintenance consideration, of course,

The main products of the control cable are polyvinyl chloride insulated control cable natural - styrene butadiene rubber insulated control cable and polyethylene insulated control cable three series. In addition, there are crosslinked polyethylene insulation and ethylene propylene rubber insulation products. The oil-impregnated paper-insulated lead-covered control cables produced in the early years have been eliminated. In order to ensure that the control cable in the event of insulation breakdo

For the common faults of power cable is the basic knowledge of each cable factory, we have these basic knowledge can avoid being caught off guard after the fault occurs, and deal with the fault in time, then what are the common faults, let the Tianxing cable Xiaobian take you together to understand the common faults of power cable and the way to eliminate.

Power cables are widely used because of their low failure rate, high safety and reliability. However, once a failure occurs, maintenance will be more difficult and dangerous, so attention needs to be paid to maintenance and testing. The following Tianxing cable Xiaobian to analyze the maintenance of power cables need to pay attention to several problems.

Flame retardant wire and cable has special flame retardant, low smoke, smoke suppression performance. What flame retardant properties should cable material have? The following Tianxing cable Xiaobian to give you a detailed description of the types and performance of flame retardant wire and cable, I hope to help you!

The composition of the power cable is: conductive wire core, insulation layer, protective layer. Detailed classification (high pressure, low pressure will not say) : conductive wire core, inner semiconducting layer, insulation layer, outer semiconducting layer, copper shield, filler, lining layer, double steel belt protective layer, outer protective layer.
