· Summary

ROCKWILL® Electric strives to bring our customers the latest technology and competitive pricing and best service for distribution automatic.
RPS is an SF6-insulated, outdoor pole mounted load break switch family for overhead lines and specifically designed for use in modern remote controlled distribution automation systems. The RPS offers reliable maintenance free operation even in the most demanding climatic conditions including salt laden atmospheres, corrosive industrial pollution, snow and ice. It has excellent load breaking and fault making capacity and satisfies the isolation requirements specified for load break switch. The earthed metal tank prevents all possible leakage currents across an open switch. RPS can be manually operated or motor operated for local and remote electric control, upgraded.
