CHN3-12Q/190 1600A 10kV Epoxy Resin Insulators Contactor Box Spolt Bushings
Description:
1.The APG process includes three processes: pre-mixing, automatic pressure gel, and solidification after molding.
2. APG process equipment mainly includes mould, Pre-mixing capacity, mobile injection special pressure vessel, full hydraulic automatic pressure gel molding machine, air compressor, after solidification need oven and necessary auxiliary machine.
3. In pouring, pouring material is the key. It has a great influence on the reliability and stability of cemented pole. For example, Xiamen H Electric Switching Co., Ltd. uses the resin materials of Vantico, Switzerland, and adopts different formulas according to different current, etc. to meet different working conditions. For example-40 ℃-250 ℃.
4. The interlock of high voltage switchgear is an important measure to ensure the safe operation of power network, ensure the safety of equipment and person and prevent misoperation. This is also clearly stipulated in GB3906, 3-35kV AC Metal Closed Switch Equipment.
5. Generally describe the interlock as: prevent misdivision, Misfit circuit breaker: prevent load separation, close isolation switch; Prevent the connection line(ground switch): prevent the connection line(switch) closed circuit breaker, load switch: prevent the accidental electrical interval.
