pm | | Embedded Pole factory (6th Dec 22 at 2:44am UTC) | | Our advantage:
1). High vacuum degree, most embedded poles鈥?vacuum degree is N*10-5Pa;
2). Low leakage rate;
3). Low circuit resistance;
4). Stable short-time(1min) power-frequency withstand voltage;
5). Epoxy resin is purchasing from China best quality supplier, other parts are also with high-quality.
6). The self-developed new product鈥斺€斺€渧acuum interrupters for switched capacitive load鈥?obtained provincial certificate for scientific and technological achievements, reaching the domestic first-class and internationally advanced level.

Qualification:
Sharp edge of a sword comes out from grinding, and plum blossom's fragrance comes from the bitter cold. Relying on technological innovation, market opening, Dayu Hanguang begins to take shape with modernized infrastructure, advanced production lines, sophisticated measurement and inspection instruments, high-quality products, excellent technical services. It has established a perfect quality management system and a mature social marketing concept, winning a certain status in the industry.
Package:
1). The packaged embedded poles can be transported by vehicles, trains, airplanes, steamship and other vehicles, during automobile transportation, the allowable degree of turbulence is equivalent to a car traveling at a speed of 20km/h on a third-level road.
2). Embedded poles should be stored in the ventilated, dry, non-corrosive atmosphere room.
3). Each embedded pole is accompanied by a product certificate, and each box is accompanied by an installation manual.
4). The storage warranty period is eighteen month.(From the dispatch date)
Annual meetings and employee activities:
Dayu Hanguang always takes improving the treatment of employees and increasing the salary of employees and seeking more benefits for employees as the purpose. The company organizes internal activities and outdoor expansion every year. Every Spring Festival annual meeting is a carnival for employees.
When drinking the water, think of its source. Dayu Hanguang always remains true to its original aspiration, and regards "people oriented, returning to society" as the mission of the company. The company vigorously developed charitable cause, donating to disaster areas and supporting the reconstruction with a free investment of nearly 100,000 yuan.Embedded Pole factory
