RVB-40.5kV Outdoor VCB

brief introduction

ROCKWILL developed RVB-40.5 series of outdoor vacuum circuit breaker using modern processing technology and computer-aided design techniques, combined with the latest generation of insulation technology coupled to magnetic actuated and spring mechanisms.
_RVB-40.5 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-40.5N ordinary outdoor vacuum circuit breakers, spring actuator comes standard with a mechanical design life of 10,000 times.
_RVB-40.5M is an magnetic actuator mechanism type VCB, which provide with a mechanical design life of 60,000 times.
