Dis Sub-12 SF6 Gas Insulated Switchgear

Dis Sub-12 SF6 Gas Insulated Switchgear

Dis sub ring main unit series are gas insulated & enclosed metal switchgear which are all for independent research and development  productions.  This  switchgear  adopts  SF6  gas  as  the insulating  and  breaking  medium,  load  switch, vacuum circuit  breaker and electrified  busbar are sealed  in one full-sealed stainless  cabinet with fixed  pressure. Externally, the us&european standard bushing are connected with in and out cables through cable connectors to form an full-sealed and insulated structure which can effectively prevent flood and resist stains, and suitable for all kinds of serious environments, and also widely used for 12kv ring network power supply or terminal power supply systems.

Product Features

Maintance Free

SF6 gas, movable and fixed contacts, arc-extinguishing chamber and busbar are sealed in one gas box. Maintance-free life is 30 years.

Reliable Mechanical Interlock

It has many reliable mechanical interlock and simulation identification on the cabinet panel to ensure safe operation.

Full-Sealed And Insulated In-Out Cables

Adopting corresponding full-sealed and insulated cable connectors as the requirements of users. Electrified display functions can show status of each circuit exactly.

Modularized And Expansible

Combination of expansible modules, one box contain 5 modules maximally, and contain more modules through the extension of busbar.

Multiply Connection Schemes

As the requirement of users,adopting load switch,load switch+fusible cutout, or vacuum circuit breaker combinations to meet the needs of various incoming and feeder line circuit.

Visible Open Connects

Through the observation window on the panel, we can see the open connects of load switch or the positions of grounding switch.

Electric Operation, FTU

Adopting special voltage transformers to collect electricity, provide power supply for operating mechanism and ftu, and measure the signals of protective voltage. Install the special battery and charging modules to ensure the continuous power supply for operating power resource and ftu. Supporting ftu mechanism with corresponding functions according to the requirements of users.
