1.Flexible operation,convenient:The new design of small hand-electric integrated spring mechanism,with functions of automatic storage,switch closing,opening driven by electricity,while such functions can also be realized manually.

2.Reliable Sealing Performance:the use of mature sealing structure technology to ensure good air impermeability.

3.Excellent insulation performance:the outgoing bushing is synthesized by APG process,with sufficient insulation distance and safe operation.

4.Maintenance-free:The main circuit and secondary components are sealed by SF6 (0 gauge pressure),and unaffected by the external environment.
