Electrical switching station

摘要

The station (10) has a housing with a housing wall (11) comprising a cylindrical hole (14), where a corrugated hose (12) is inserted into the hole. An annular gap (18) is formed between the hose and the hole. An O-ring (20) is arranged in the gap and inserted on the hose. Dimensions of the hose, the hole and the O-ring are matched with each other such that a gas-tight connection is formed between the hole and the hose. A bushing (21) is arranged in the gap. The hose is formed of corrosion-resistant metal alloy. The O-ring is made of elastomer or rubber. The housing is designed as a crankcase of a switching device pole.
