Main Features

·Environmentally friendly

HG6-72.5kV environmentally friendly gas insulated switchgear (MTS) uses dry compressed air as the insulating medium and has no impact on the environment. It is a green product. No gas ventilation and protective equipment is required at the site.

·High safety and reliability

The HG6-72.5kV environmentally friendly gas insulated switchgear (MTS) is a phase-separated switchgear that greatly reduces the risk of phase-to-phase short circuits. Multi-compartments independence can effectively reduce the scope of internal faults.

·Flexible structure

HG6-72.5kV environmentally friendly gas insulated switchgear (MTS) adopts circuit breaker unit and EDS unit, which are respectively installed in independent aluminum tanks, separated into independent gas compartments by disc bushings, and the outgoing bushing unit and the EDS unit is also isolated into a separate gas compartment by a disc bushing. The structure is very flexible and can be adapted to different primary schemes, and is a plug-and-play switchgear.

·Frequent operation

HG6-72.5kV environmentally friendly gas insulated combination (MTS) uses vacuum circuit breakers, which can be used in frequent operation.

·Maintenance-free

The main circuit high-voltage components of the HG6-72.5kV environmentally-friendly gas-insulated switchgear (MTS) are sealed inside the cast aluminum tank, which is a maintenance-free product.

·Wide environmental adaptability

The HG6-72.5kV environment-friendly gas insulation switchgear (MTS) adopts clean and dry compressed air as an insulating medium, can be used in a low-temperature environment, does not have the liquefaction risk, and has wide environmental adaptability.
