RPS Outdoor Pole Mounted SF6 Kema Certificated Load Break Switch
RPS FeatureThe high quality 3 mm stainless steel are used for tank, which is designed for its maximum robustness and minimum welding line to minimize corrosion, and specifically to guarantee the safety of the operation personnel even with the internal arc faults at the maximum fault capacity of the tank the RPS can withstands an internal fault without venting hot gases.
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.
The independent spring operation mechanism adopt ROCKWILL® patent spiral spring, provides a guaranteed load break fault make capability by ensuring the opening and closing speed of the switch.
The RPS is provided with light reflecting position indicator which are directly connected to the switch operating shaft providing clear and unambiguous switch position indication. Indicator made of light reflecting material, which is easily visible from ground level even at night in driving rain.
