ABSTRACT:
A high voltage electric cable termination module that is characterized by having a gas-restricting valve mounted on it adjacent one of its ends to impede the flow of hot, ionized arc-generated gases from the module, when an arc is formed by interrupting an electrical circuit within the module. The gas restricting valve is adapted to cooperate with either a movable contact member, or an arc follower, of a second module that is adapted to cooperate with the first module to form a plug-in type connection between a pair of electrical conductors that are housed, respectively, in the two modules. By restricting the flow of ionized gas from the modules, their arc-interrupting capability is enhanced and at the same time the risk of an arc re-strike between the conductors of the separated modules is appreciably reduced.
