ZW2ox-12 Series Outdoor HV vacuum breaker (hereinafter referred to as breaker) for the rated voltage of 12KV, three-phase AC 50Hz outdoor distribution equipment. It uses a vacuum interrupter and SF6 gas as insulating medium, the ZW20-12-type colunw vacuum breaker improved products. Box with the introduction of Japan's Toshiba Corp. VSP5 gas sealed, explosion-proof, insulation technology, into the outlot duct has also been sealed divergence one can improve the overall sealing performance, not the internal filling of SF6 gas leakage from the external environment impact, the spring operating mechanism for a small design and optimize the reliability and stability, the use of direct-actinc chain primary drive and multi_level release system, operating reliability and stability operations than domestic institutions to enhance the traditional spring several times, main circuit contact between the shaft and sleeve with a bracelet style sheets adductior structure, the main circuit of the contact resistance, low temperature rise. So Zw2ox-12 type outdoor vacuum circuit breaker is a kind of surgery on the maintenance-fre product is the circuit breaker in the column to share. <br> zw2ox-12 than the Zw2o-12 also increased the over-curent protection, institutions spring energy storage instructions, and dirty air outlet is allowed to develop with the secona electrical connection, easy and intelligent controller combination. Excellent electrical ana institutional performance, the column Zw2ox-12 type outdoor vacuum circuit breaker is widely used. Mainly used for breaking, closing 10KV power system control facilities, with excellent function of coincidence, to meet the distribution automation system.

Physical dimension
Environmentally friendly gas-insulated metal enclosed switchgear is the most commonly used three-phase intelligent gas-insulated AC cabinet and is widely used in various switchgear sets, with population concentration in the country, the power market must be supported, environmentally friendly gas-insulated switchgear will also grow with market development; market potential is yet to be tapped. At the same time, as the product integrates data collection and management, data processing and storage, online monitoring of switchgear, advanced analysis, and other multifunctions in one, network intelligent monitoring and management of the distribution network, so that the distribution network operates in a safe, reliable, high-quality, and efficient best state, to achieve remote monitoring, management, and control of the power system distribution network, to achieve network optimization, safe electricity use, power management, energy saving, and consumption reduction; at the same time, the system can be widely used in intelligent power distribution fields such as transportation, factories, hospitals, schools, buildings, residential areas, and commercial office buildings.
