GTXGN-12 Intelligent solid insulation cabinet

Product overview

Sulfur hexafluoride widely used in the high voltage electrical industry as the excellent insulation and ARC cancellation performance . There are nearly 50% of the Sulfur hexafluoride produced all over the world applied to electrical industry . But there is inevitable leakage emissions when inflatation, operation, and recovery . It is an important pollution source in the atmospheric environment , it has seriously damaged the human living environment .

SF6  gas molecules have a lifetime in the atmosphere of 3400 years, beyond the harsh bad effects of co2 gas obviously . SF6 gas concentration is rising upward these years, It has attracted high attention from the international community .

Hence, try the best to use the SF6 as little as possible , promote new technologies and alternative products have become the common view in the high voltage production industry .

The company follow the principle , on the basis of systematic research, learning , research and development SGXGN-12 type solid insulation ring main unit .

The intelligent solid ring main unit is the 3.6kV ~ 12kV, AC three phase 50 Hz , single busbar and single barbar segment system complete set device . 

This switchgear compliance with standard  IEC298 ，  GB3906-2006 ， GB1984 ，Etc , The switch and main components are integration module . The part of phase conductor is the solid insulation encapsulation .

This kinds of intelligent insulation cabinet have the features of simple structure,  flexible operation , interlock is reliable and easy for installation , provide the satisfied scheme for different clients and different applications .  Sensor technology, automation technology , information technology and advanced technical performance ,can meet the changing requirements of the market  and intelligent power grid . This ring main unit suitable for the power system of 50Hz , 12kV . widely used in industrial and civil cable ring network and power distribution terminal engineering .it especially suitable for power distribution in urban residential areas, small secondary substation, switching substation, cable branch box, box substation, industrial and mining enterprises, shopping malls, airport, subway, wind power generation, hospital, stadium, railway, tunnel, etc. 

This product has the advantage of fully insulated, fully sealed, and fully screened , especially suitable for high altitude, high temperature, hot and humid, cold, strict pollution and other areas with harsh environment.

Characteristics

1.  Environmental protection

All the materials selected are non-toxic and harmless substances during production .

2.  Wide use scope

The isolator switch operating mechanism box adopts sealing structure , full of dry nitrogen , no SF6 , fully isolated from the external environment to ensure the use of the switchgear in full working conditions .

3 . Convenient for transport and installation

Single body structure , Unified design of all series products , provide a variety of cabinet types (circuit breaker cabinet, load switch, fuse load switch cabinet ,measurement cabinet , PT cabinet , busbar cabinet, bus compler cabinet to the clients , The appearance and dimensions are exactly the same , the insulate busbar , cable plugs made by the professional cable accessories manufacturer,

Switch cabinet can be combined on site and expanded , avoid the transportation inconvenience of  multiple groups combination cabinets.

4. Maintenance free

Solid insulate cabinet indoor AC high voltage switchgear except the operator , The high-voltage switch part is fully sealed ，this achieved free from cleaning and maintenance, it reduces operating and maintenance costs  .

5. Safety

As the touching parts adopt the shielding measures, it eliminates the occurrence of personal electric shock accidents and improves the operation safety .
