outdoor medium voltage vacuum circuit breaker

Features of ZW32 outdoor mv vacuum circuit breaker:

1 The shell is made of a high-quality stainless steel material or ordinary steel plate by Dacromet anti-rust treatment process and then sprayed with UV-resistant varnish. The anti-corrosion and anti-salt properties of the product are excellent in environmental resistance.

2.Insulation part is made of epoxy resin and silicone rubber composite insulation material. It has a high insulation grade, strong anti-pollution ability, ozone resistance, UV resistance, hydrophobicity, and high and low-temperature resistance. There is no transformer oil and no sulfur hexafluoride gas in the tank, which meets the requirements of oil-free transformation and environmental protection.

3 The operating mechanism is a spring operating mechanism, which is available in manual or electric mode. It can be equipped with a remote control device and avoiding the inrush current device when needed. The required external power supply is no more than 70W, and it is easy to equip with backup power. The unique design of the buffer device, excellent performance, small rebound, low noise.

4. The arc extinguishing chamber adopts special stainless steel brazing technology, no need for electroplating, high welding quality, stability and reliability, and low air leakage rate. The special ceramic metallization formula and advanced ceramic metallization process are used in the production process to ensure the airtightness of the product, and the tensile strength is greater than 130Mpa, which is completely sealed.

5.The current transformer is made of high-quality magnetic conductive material and epoxy resin and silicone rubber composite insulation. It has the advantages of large capacity, high dynamic heat stability multiple, high precision grade, maintenance-free and high reliability.

6. According to the needs of users, it can be combined with the corresponding controller to form an automatic recloser and a segmenter. It is an ideal device for realizing distribution network automation.
