Medium voltage high voltage outdoor isolating switch disconnecting switch

Products Description

medium voltage (MV) or high voltage (HV) outdoor isolating switch, also known as a disconnecting switch, is a type of electrical switch that is designed to isolate a specific section of an electrical circuit. It is commonly used in power transmission and distribution systems to ensure the safety of maintenance personnel and to protect the electrical equipment from damage during maintenance activities.

The isolating switch or disconnecting switch is used to disconnect a section of the circuit from the rest of the system to allow maintenance work to be carried out safely. They are typically installed in outdoor substations or on overhead lines, and are rated for a specific voltage level depending on the requirements of the application.

In addition to their safety function, isolating switches can also be used to switch loads on and off, although they are not designed to break load currents. They are also used in conjunction with circuit breakers, which are responsible for interrupting the current flow in the event of a fault or overload.

Isolating switches are available in a variety of designs and configurations, including vertical and horizontal mounting, and can be operated manually or electrically. They may also include additional features such as interlocks and earthing switches to provide further protection to personnel and equipment.
