Medium voltage switchgear is electrical equipment used in power systems with voltage levels between 3kV and 40.5kV. It primarily controls, distributes, and protects electrical energy, and is a crucial link in the safe operation of the power grid and users.

There are many types of medium voltage switchgear. Our company’s product types include KYN28 series metal-clad switchgear, HXGN ring main unit, DXGYRQ series mv soft starter panel, medium voltage vfd panels, gas-insulated switchgear, etc. For more product types, please view our company’s product website.

The Role of Medium Voltage Switchgear

Power Distribution

MV switchgear distributes electrical energy from transformers or the power grid to various load points, such as distribution panels, factory equipment, or building power systems.

System Protection

In the event of faults such as overloads, short circuits, or ground faults, mv switchgear can quickly disconnect the circuit to protect both equipment and personnel.

Isolation and Maintenance

With isolating switches, mv switchgear ensures the complete disconnection of power during equipment maintenance, providing reliable safety assurance.

Main components of medium voltage switchgear

The switchgear consists of two main components: the conductive system and the protective system. This includes equipment such as regulating panels, voltage transformers, switches, isolators, circuit breakers, current transformers, lightning arresters, and other related equipment. Some of these devices are able to act as protection devices by monitoring and detecting faults in the system, while others are primarily focused and designed to function as switching devices that open or close.

MV switchgear is widely used in industrial, commercial and urban power grid scenarios, covering power distribution, protection control and automated monitoring. It is a key equipment to ensure the safe transmission and distribution of electricity.

MV switchgear is a crucial bridge connecting the power grid and power loads. It not only distributes electricity but also plays a key role in protecting the grid and power equipment. With the development of smart grids, modern medium-voltage switchgear is evolving toward intelligent, modular, and environmentally friendly features, finding widespread application in industrial, energy, and urban power distribution systems.
