Product Description

1. Detail description

    ZW**-type outdoor high voltage vacuum circuit breaker for rated voltage *2kv three-phase AC *0Hz outdoor distribution equipment applies to power distribution system substation and industrial and mining enterprises to do to protect and control, and rural power grid frequency operation premises. It is mainly used for breaking and closing the power system load current, overloads current and short-circuit current.

    Vacuum interrupter outdoor insulation using silicon rubber sleeves, long life, high reliability and good weather resistance, easy to transport, cost-effective, operating organizations to adopt a small, high reliability spring operating mechanism, simple structure, mechanical life of up to *0,**0 times.

    The circuit breaker can be with controller as recloser, to achieve remote control, telemetry, remote, remote adjust, four remote features.

 2.Features:

 

no combustion and explosion hazards, maintenance-free, small size, light weight (less than **0kg), long life (****0 times), safe, reliable, simple operation, maintenance and easy installation.

3.Advantages & Features

1.    ZW*2 *2kv outdoor medium voltage vaccum cricuit breaker 
2. CE,CCC, ISO********8 Certificated 
3. *5Years production experience

It has advantage of firm structure ,high reliability , contact from the large open, better breaking capicity and smaller bounce at contact closing and opening , and long life ,minimum maintenance demended during its whole lifetime ,high frenquency of repeated switches ,small size and low weight.

The products developed by CHENNUO,as the equipment of electrical control switchgear  ,are mainly used in petroleum ,chemical and other fields .Because of the excellent breaking performance of vacuum contactors ,the vacuum contactorss can operate in particularly harsh conditions . In terms of the control and protecion of motros ,transformers ,capacitor banks ,and switching systems etc.  They have excellent performance .
