● Summary

ROCKWILL® Electric endeavors to bring our clients the most recent innovation and focused estimating and best assistance for conveyance programmed.

RPS is a SF6-protected, open air shaft mounted burden break switch family for overhead lines and explicitly intended for use in present day remote controlled conveyance robotization frameworks. The RPS offers dependable upkeep free activity even in the most requesting climatic conditions including salt loaded environments, destructive modern contamination, day off ice. It has astounding burden breaking and deficiency making limit and fulfills the disengagement prerequisites determined for load break switch. The earthed metal tank forestalls all conceivable spillage flows over an open switch. RPS can be physically worked or engine worked for nearby and remote electric control, overhauled.

● Service condition

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

Stickiness: Monthly normal mugginess 95%; Daily normal moistness 90% .

Height above ocean level: Maximum establishment elevation: 2500m or increasingly higher.

Surrounding air not evidently dirtied by destructive and combustible gas, fume and so on. No regular savage shake

● RPS include

The excellent 3 mm tempered steel are utilized for tank, which is intended for its greatest heartiness and least welding line to limit erosion, and explicitly to ensure the wellbeing of the activity staff even with the inside curve shortcomings at the most extreme deficiency limit of the tank the RPS can withstands an inner issue without venting hot gases.

The autonomous spring activity component embrace ROCKWILL® patent winding spring, gives an ensured burden break deficiency make ability by guaranteeing the opening and shutting rate of the switch.

The RPS is given light reflecting position pointer which are straightforwardly associated with the switch working shaft giving clear and unambiguous switch position sign. Marker made of light reflecting material, which is effectively noticeable from ground level even around evening time in driving precipitation.

● Main new points of interest of RPS

ROCKWILL® Supply extraordinary plan manual shutting gadget innovation with claim patent, It applied for typical and unusual circumstance shutting. It's end speed(time) agree to IEC62271-100.

This capacity can counterbalance from attractive actuator flaw which when actuator can't work will cause the significant mishap.

Consumption safe, Composite bushingManual lock-out instrument (counting snare stick) Reliable lodging groundO/C pointer (made of light reflecting material), Operation counter, Gas thickness check which are effectively unmistakable from ground level.

Progressed and Integrated helium spillage identifying and filling gear, which guaranteeing SF6 spillage of each switch is under 0.1% carefully every year.

Engine drive, which effectively retrofitted nearby to physically worked units.
