High voltage switchgear is a device used to control and protect high voltage power systems. Usually composed of one or more switches, used to control the on-off and on-off of the power system to prevent power failure and overload. High-voltage switchgear is generally used in substations and distribution rooms and other places for connecting and controlling various power equipment.

A cable branch box is a device used to branch and connect cables. Usually consists of multiple cable sockets and connectors for branching the main cable into multiple branch cables for connection to different devices or power supplies. Cable branch boxes are generally used in the wiring and distribution of power systems to connect cables and provide power supply.

As far as the structure is concerned, the high voltage switchgear is generally composed of a metal shell and an internal switching element and an electrical control device. Good insulation and protection levels are required to ensure safe operation in high pressure environments. The cable branch box is usually made of fireproof material as the shell, and is provided with the corresponding cable socket and terminal to facilitate the connection and branch of the cable.

In terms of use, the high voltage switchgear is mainly used to control and protect the high voltage equipment in the power system, such as transformers, generators, etc., to ensure the normal operation of the power system and prevent power failures and accidents. The cable branch box is mainly used for the branch and connection of the cable to guide the power from the main line to the specific equipment or use.
