●Summary

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.

●Service environment

1.Air temperature: Maximum temperature: +85℃; Minimum temperature:-45℃

Humidity: Monthly average humidity 95%; Daily average humidity 90% .

Altitude above sea level: Maximum installation altitude: 2500m or more higher.

Ambient air not apparently polluted by corrosive and flammable gas, vapor etc. No frequent violent shake

●RPS feature

The 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.

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.

● Main new advantages of RPS

Supply special design manual closing device technology with own patent, It applied for normal and

abnormal situation closing. It’s closing speed(time) comply with IEC62271-100.

This function can offset from magnetic actuator fault which when actuator can’t work will cause the major accident.

Corrosion resistant, Composite bushing

Manual lock-out mechanism (including hook stick)

Reliable housing ground

O/C indicator (made of light reflecting material),

Operation counter, Gas density gauge which are easily

visible from ground level.

Advanced and Integrated helium leakage detecting

and filling equipment, which ensuring SF6 leakage of

each switch is less than 0.1% strictly per year.

Motor drive, which easily retrofitted on site to

manually operated units.
