As the load current changes and the ambient temperature changes, the power cable will undergo thermal expansion and contraction. The thermal expansion and contraction of the core produces a very large thermomechanical force. The larger the cross section of the cable core, the greater the thermome...

The cable branch box is only used as a cable branch. The main function of the cable branch box is to branch or transfer cables, which is mainly used for cable branching and cable switching. With the development of the distribution network cable formation process, when small-capacity independent l...

The Ring Main Unit is used in the ring network power supply to connect two power sources or parts of a switch cabinet. The main function is to split the two sections, with single function and small size. The center cabinet is a type of switch cabinet used by end users, with full functions and lar...

The main difference between a touch cable connector and a live non-touch cable connector is that the silicon rubber cable connector of the former has a semiconductor shielding layer inside and a conductive shielding layer outside. It is connected to the ground through a financial hoop to ensure t...

In addition to different functions, installation environment, internal structure, controlled objects, etc., distribution boxes and switch cabinets are distinguished by different dimensions. The distribution box is small in size and can be hidden in the wall or stand on the ground. However, the sw...

Everyone knows that the wires in the cable have different colors. What are these colors used for? What does the color on the cable mean?

Switchgear refers to a complete set of power distribution devices assembled from primary equipment and secondary equipment according to a certain plan, which is mainly used to control and protect circuits and equipment. Switchgear can be divided into high voltage switchgear (fixed type and handca...

The difference between zinc oxide arrester and elbow arrester 1. (1) Working principle of valve-type arrester: When the system is normal, the spark gap isolates the valve plate resistance from the working bus, so as not to burn out the valve plate resistance due to the current generated in the va...
