This product is equipped with GT-SRM-12 series SF6 gas insulated ring main unit and GTRM-12 type Solid insulated ring main unit, which has the functions of full insulation, full sealing, dust proof, corrosion resistance and maintenance free. It can realize the combination of different schemes and meet various wiring modes. The ring main unit in the opening and closing station can also be combined with 10kV power supply PT, distributed power module, DTU, communication control terminal to realize the automation of medium voltage distribution network, which greatly improves the reliability of the urban power supply and distribution network. Its simple, convenient, flexible connection combination, economic, reliable, durable structural features, become the distribution network cable engineering of the first choice of equipment.

The internal configuration of SF6 gas insulated ring main unit or
Solid insulated ring main unit,
with fully insulated, fully sealed, miniaturized, maintenance-free
and other features, can be
free from the impact of the external environment;

The modular design can realize the free combination of different
modules to meet the requirements
