A vacuum interrupter has a housing with at least a first metal flange through which a first connection pin extends into the vacuum interrupter in a vacuum-tight manner to a first contact. The housing has at least one insulating-material housing region formed by a disc-like insulator. A second connection pin extends into the vacuum interrupter in a vacuum-tight manner to a second contact. The vacuum interrupter can be produced in a cost-effective manner with a compact construction. There is also described a switch pole for a switching device having a vacuum interrupter.

An insulating resin for switch gears on the basis of glycidyl ester contains methyl nadic anhydride/hydrogenated methyl nadic anhydride as hardener and an N-substituted imidazole as accelerator. Furthermore, platelet-shaped alumina is added as a filler. The resin has a substantially elevated glass transition temperature, while at the same time having a high mechanical level and being very tracking resistant. It is suitable as a casting resin in gas-insulated transmission line systems.

A circuit breaker device has a first electrode piece and a second electrode piece. In order to ensure protection from weather, the circuit breaker device is equipped with an electrically isolating housing. The electrically isolating housing has a first shell and a second shell. The first shell serves as a volatile casing for the second shell during production.
