Model Description

The RGW1-24 outdoor three pole disconnector with fuse holder is a type of high voltage switch equipment. It is suitable for use in energized, non-loaded outdoor 24kV distribution lines for circuit disconnecting. It is equipped with a CS8 manual operating mechanism, so misoperations like earth wire grounding when energized can be avoided. The pollution-proof type isolator switch can be used in filthy areas and it can solve the problem of shed pollution during working.
