SHME Outdoor high-voltage vacuum circuit breakers which installed on transmission line poles are suitable for power distribution systems with three-phase AC 50Hz and rated voltage 12KV and below. They are mainly used for breaking and closing the load current, overload current and short-circuit current of the line. The sectional switch for rural area power grids and small power systems, and It is an upgraded product for the transformation of urban power grid and rural power grid. It has the characteristics of small size, light weight, anti-condensation, maintenance-free, etc., and can adapt to relatively harsh climatic conditions and dirty environments.
Some company's name is PVB, which means pole-mounted vacuum circuit breaker.
For a smart, flexible grid, SHME's Outdoor VCB is the most flexible, intelligent and reliable device, we can provide the most complete functions and the most flexible installation to suit various occasions.
SHME Outdoor VCB can meet various protection requirements of the power grid, including making and breaking short-circuit currents.
SHME Outdoor VCB has very good performance in the occasion of frequent operation, SHME Outdoor VCB can fully meet the requirements of automatic reclosing, with high reliability and electrical life.
Using SHME's remote control device, At thousands of miles away in the office it is possible to open and close the Outdoor VCB. The action is reliable, timely and accurate. SHME's remote control device is small, flexible, intelligent, stable and reliable. It can be installed alone, or together with the protection device to form a protection system, and can also be used in a prepaid electricity system. It can also be used as a node of the power grid to flexibly configure the distribution of power.
