JouYang Electrical: vacuum circuit breaker manufacturer and vacuum circuit breakers design in China.

Established in 1990, China JouYang Electrical Products Co.,Ltd. is known as a leading vacuum circuit breaker manufacturer and designer of high and low-voltage electric appliance in China. We integrate scientific research, development, production, sale and service in one company. Our custom vacuum circuit breakers products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM vacuum circuit breaker products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

ZN39-40.5C type vacuum circuit breaker is three-phase 50Hz AC indoor power distribution device with the rated voltage of 40.5kV. Matching with JYN1-35/GBC-35 type switchgear, it is mainly used in power transmission and distribution system of power station and substation as controling and protecting devices. It is suitable for the place where it is operated frequently.The circuit-breaker has the advantages of reasonable constructure, easy maintenance , safe and reliable usage. It can be equipped with CD10- type electromagnetic operating mechanism or CT19- type spring operating mechanism. The elevation should be no higher than 1000m. Ambient temperature: The max. temperature should be +40℃. The min. temperature should be -10℃. Relative Humidity: The average humidity of a day should be no more than 95%. The average humidity of a month should be no more than 90%. Saturated Vapour pressure:The average saturated vapour prereure of a day should be no more than 2.2×10-3 Mpa; The average saturated vapour prereure of a day should be no more than 1.8×10-3 MMpa. It should be used in the places without fire, explosion, serious filth, chemical erosion and violent vibration.

VS1 type indoor high voltage vacuum circuit breaker with the rated voltage of 12kV and the three-phase alternating current 50Hz, is used to switch on/ off all kinds of electrical load with different nature and suitable for the electrical network construction and reform projects for city network, country network, mining area and railway etc. especially for the fields that takes the frequent operation within the range of working current and have the strict demand on short-circuit drop-out operating times. This product adopts the mechanism and circuit breaker one body design, can be used as a fix installing unit and drawable cart unit.This product is in comformity with the standards of IEC 56, B/T3309, GB7675, GB/T11022, JB3855, DL402. Vacuum circuit-breakers are nowadays indispensable medium-voltage components for the use, restructuring, modernisation and new installation of switchgear. Ormazabal Anlagentechnik GmbH vacuum circuit-breakers have the following special features: Compact design. Simple and robust drive
Long life and low maintenance. Up to 30,000 switch cycles at rated operational current (on request)
