Product Description

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.

Our Advantages

    The traditional way of reactive power compensation is changing the quantity of capacitors to adjust output reactive power, change method is usually switch or contactor, will result in following hazards:
1. The conventional reactive power compensation method has a large compensation capacity and the adjustment is not flexible, it will lead to the compensation is not suitable , often appear over and not enough.
2. The capacitor switching can cause over-voltage and inrush current, and it will seriously affect and reduce the service life of the switch. 
3. When the capacitor is switched on, as the capacitor will charged and discharged, when it need to switch on again, which affects the speed of the switching..
       According to the above problems, our company developed the FLYK type reactive power compensation device, has the following 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.
(6) Fast Deliveries
Strong manufacture capacity to satisfy urgent leading time. It is around 15-25 working days after we receive the payment. It varies according to the different products and quantity.
(7) OEM ODM and MOQ
Strong R&D team for quick new products' development, we welcome OEM, ODM and customize request order. Whether selecting a current product from our catalog or seeking engineering assistance for your application. You can tell us about your sourcing requirements 
Normally our MOQ is 100pcs per models. We also produce OEM and ODM as you requirement. We are developing worldwide agent.
