Electrical joint compound

A compression electrical-mechanical joint for electrically and mechanically connecting the bared ends of electrical power cables capable of carrying heavy current in power distribution systems, characterized in that the joint has an electrical conductance at least substantially equal to an equal length of conductor, capable of maintaining high conductance and mechanical strength over a very great number of thermal recyclings which comprises

• a connector body having a tubular portion,
• the bared end of an electrical conductor in said portion,
• a highly thermally conductive compound comprising a thermosetting hardened resin containing a uniformly dispersed mixture of fine and coarse metal particles, said fine particles being 200-500 mesh, said coarse particles being 10-100 mesh, the ratio by weight of coarse particles (C) to fine particles (F) being expressed by:
• C/F-1/20 to 1/1,
• the ratio by weight of all metal particles (P) to resin (R) is expressed by:
• P/R=3/2 to 6/1
• and in which the tubular metal portion has been compressed onto the cable end with a force intensity sufficient to have substantially reduced the diameter of the cable and to produce substantial contact between the inner surface of the connector body and outer surface portions of the conductor.
