Abstract
A method and apparatus for preventing birdcaging of a conductor having multiple strands when these conductors are installed in a connector utilizing high speed installations, such as by an explosively-operated tool. The inside surface of the connector is coated with a mixture of 30% silica sand and 70% of PENETROX.RTM. A13 to reduce contact resistance. A wedge is then inserted into the connector between the conductors utilizing the explosively driven tool.
Claims3
A method of securing a pair of electrical conductors to a connector without creating a birdcaging effect, comprising the steps of:
- coating a portion of the inner surface of the connector with a material comprising a mixture consisting of 30% by weight of silica sand and 70% by weight of a synthetic base vehicle in which zinc particles are suspended to reduce the contact resistance between the connector and the conductors;
- and
- inserting a wedge member into the connector between the two conductors utilizing an explosively driven tool.
A C-configured connector used to prevent birdcaging when a wedge is explosively propelled therein, the C-shaped connector provided with an inner surface having first and second radius sections connected to an inner flat section, and a material comprising a mixture consisting of 30% by weight of silica sand and 70% by weight of a synthetic base vehicle in which zinc particles are suspended applied to the inner surface of the C-shaped member, said material used to reduce the contact resistance between the conductors and the C-shaped connector.
