Overview
ZW20 series circuit breaker 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.

WE COMMITTED TO PROVIDE A BETTER POWER.
Our Advantages
(1). Energy conservation: Farady voltage regulating type capacitors will change the output reactive power by regulating voltage on capacitors, so that the reactive power can be adjusted smoothly. Comparing with other method, it can ensure the capacitors in best condition, the energy saving effect is much better(2). Low cost:If the old power transformer substation need to reform, only need to add a voltage regulator between the circuit breaker and capacitors, the original circuit breakers, reactors, capacitors can be reuse, greatly reduce the cost of transformation
(3). Maintance Free:When traditional circuit breaker and contactor switching, switching devices and capacitors often damaged because of the above problems, result in high maintenance costs, using Farady devices, automatic control reactive power output, there is no potential risks of other equipments, greatly reducing maintenance and staff costs in power transformer substation
(4) Quality Assurances
We have a strictly quality control process from the raw material to finished products. Advanced testing lab to make sure products quality and improve our creative ability. Quality and Safety is the soul of our products.
(5) Excellent Services
Many years of manufacturing experience and rich export business help us to establish a well-trained sales service team for all customers.
