Product Description

Overview

ZW20PW series SF6 recloser is the intelligent power distribution equipment which to solve the problems listed below:
1.Failures in T branch of overhead line cause the whole distribution off
2.Short circuits in the user end cause the whole distribution line off
Working with our CMS-4000 distribution automation system to switch off the short circuit failures and earthing failures automatically. They can monitor the line status, realize remote control, telemeter,  remote signal and remote regulating, and are the ideal intelligent distribution automation circuit breaker.
