Abstract
A method and arrangement is provided to form a gas-tight joint between two housing portions, e.g. between an end flange and a tubular pole-unit housing for a circuit interrupter or an insulating support column. The joint is formed via a heat-shrink process to provide an interference fit. The housing is provided with grooves to retrain adhesive during the assembly process.
