Structural features

◆The shell is made of high-quality stainless steel or ordinary steel plate through Dacromet anti-rust treatment process and then sprayed with UV-resistant varnish. The product has excellent anti-corrosion, anti-salt spray and other environmental resistance properties.

◆APG sealed insulation pole is encapsulated with silicone rubber (as insulation and buffer 1, small size, excellent anti-dew performance, long working life and reliable performance.

◆The operating mechanism is a spring operating mechanism, which is available in manual and electric versions. A remote control device and a device to avoid inrush current when closing the switch can be installed when necessary. The required external power supply power is no more than 70W, and it is easy to equip a backup power supply. The uniquely designed buffer device has excellent performance, small rebound and low noise.

◆The arc extinguishing chamber adopts special stainless steel brazing technology, which does not require electroplating, has high welding quality, is stable and reliable, and has a low leakage rate. The production process uses a special ceramic metallization formula and ceramic metallization process to ensure the airtightness of the product, with a tensile strength greater than 130Mpa, and is completely sealed once.

◆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 thermal stability, high precision, maintenance-free and high reliability.

◆According to user needs, it can be combined with corresponding controllers to form automatic reclosers and sectionalizers, which are equipment for realizing distribution network automation.
