When the power cable passes through a certain load current, it will be heated. With the increase of the load current, the cable surface temperature will be higher. If it is not handled in time, the consequences can be imagined. For example: PVC cable, the core temperature of 70 degrees is considered as the upper … Read more
One is the conductor structure.The conductor of cable is usually made of high purity copper or aluminum of certain toughness and strength with good electrical conductivity. Conductor sections are commonly used in circles and sectors. A conductor with a smaller section (less than 16 square meters) is made of a single copper wire, while a … Read more
