Abstract

An electrical coupling particularly for submersible pumps serves as a barrier between high and low pressure zones and allows electrical cables to be connected through it. The coupling includes a jacket mounted in a housing. The jacket has at least one tapered hole extending through it. A conductor rod is bonded to a dielectric sheath and inserted into the hole. The sheath is compressed in the hole to provide sealing. The sheath is preferably of glass bonded mica.
