RVB-36kV Outdoor VCB

brief introduction

ROCKWILL developed RVB-36 series of outdoor vacuum circuit breaker using modern processing technology and computer-aided design techniques, combined with the latest generation of magnetic actuated and spring mechanisms combined with solid insulation. This design concept offers high reliability, easy maintenance which makes it the best option for the electric power system.
_RVB-36 series of switches c/w Microprocessor based controls with software and solid insulation are designed with the overall safe and reliable features that a Power Network requires for Distribution Automation and Protection.
_RVB-36N ordinary outdoor vacuum circuit breakers, spring actuator come standard with mechanical life of 20,000 times.
