HXGN

Our company can produce this product with a voltage class range of 1-40.5kV and below.

The fully enclosed and fully insulated gas-filled ring main unit is a metal common box type enclosed switchgear insulated by SF6 gas. This equipment can be composed of modules such as the load switch unit, the combined electrical appliance unit of load switch and fuse, the vacuum circuit breaker unit, and the busbar incoming line unit.

By adopting a series of excellent technologies and materials, it has excellent electrical and mechanical properties, is less affected by the environment and climate, is compact in size, easy to install, convenient to operate, maintenance-free, and has a flexible combination mode.

The clear and intuitive design ensures simple and direct operation. It has a large feeder connection capacity and is suitable for a variety of wiring systems.

Through us, we can provide users with an integrated three-position load switch circuit breaker.Using a load switch instead of a disconnector is safer and more reliable. The fully enclosed design on the primary side provides protection against accidental contact,and the mechanical interlock live-line indicator that meets the "five-prevention" requirements can provide live-line indication for the incoming and outgoing lines.

Reliable operation:With a fully enclosed design, all switches and live busbar conductors are sealed in an air box welded by 3mm stainless steel plates; equipped with silicone rubber cable plugs to achieve full insulation and full sealing of the cable ends, thus not being affected by external environmental factors such as dust, humidity,and small animals.

The spring energy storage operating mechanism can be operated manually or electrically.The simulated wiring diagram on the operation panel provides switch position indication.

The cabinet body is made of galvanized steel plates and electrostatically sprayed on the surface to enhance corrosion resistance.The pressure gauge monitors the safe pressure range of SF6 gas in the box body.

The main models of this product are EWR-12, EWR-24, and EWR-40.5.

This product has the characteristics of being maintenance-free, highly reliable,with a service life of up to 20 years, having multiple incoming line methods, being able to achieve left,right,upper or front incoming lines, and multiple combination methods.

Arbitrary combination can be achieved between each unit.

Using insulated busbars, it can achieve front-to-back or left-to-right cabinet combination.The design scheme is flexible,the feeder outlet capacity is large, the floor space is small, and it is suitable for a variety of application requirements.

It is mainly applicabl to the power distribution networks of compact secondary substations, small industrial and mining enterprises, wind power plants, hotels, shopping malls, office buildings,commercial centers,etc.
