METHOD FOR PRODUCING CIRCUIT-BREAKER POLE PARTS

摘要

A process for producing a circuit-breaker pole part for use in a medium-voltage or high-voltage circuit-breaker comprising adjoining (a) an inner vacuum interrupter layer, (b) an intermediate compensation layer, and (c) an outer insulating sleeve layer, wherein the intermediate compensation layer is disposed between the inner vacuum interrupter layer and the outer insulating sleeve layer; wherein said layers are integrated with each other to form a circuit-breaker pole part; and wherein the intermediate compensation layer comprises the reaction product of (I) an epoxy-terminated prepolymer and (II) a curing agent; and a circuit-breaker pole part produced by the above process.
