The box stationary-type AC metal closed-loop network switch equipment shortly named rig-net box is produced for meeting the need of electric network reconstruct and construction in cities. It can be used to open the load current and short-circuit current and close the short-circuit current. This rig-net box is equipped with a vacuum load switch, and its operation mechanism is spring mechanism. This one can be operated not only by hand, but also by electric. The earth switch and isolated switch are equipped with hand-operating mechanism. The rig-net box packed easier, and its physical volume small, no combustion and explore risk, and has the capacity of five preventions.

 

The rig-net box is suitable for trophies AC 50Hz electric power system for distributing electric emergency. It is widely used electric network reconstruct and construction in cities industrial and mining business high-risebuilding and common facilities. As the rig-net electrical supplement units and terminal devices, it takes charge of the distribution and control of electric energy and the protection for electrical equipment. It can be also used in box-type substation. this rig-net box complies with pertinent regulations of «High-voltage AC load switch and fuse combined electric appliances »  and «3-35kv AC metallic packing switch equipment ».
