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.
