ABSTRACT:
An apparatus for preventing the twisting of electrical cables is constructed with bearing assemblies for conducting electrical current from a fixed cable end to a rotatable cable end. The apparatus employs a housing and fixed and rotatable cable clamping devices attached thereto. The housing and clamping devices cooperate to transmit tensile loads on the cable through the rigid apparatus housing thereby preventing wear and damage to the moving electrical contacts. An idler bearing is employed to minimize torsional strains on the cable conductors by permitting cable to rapidly change position within the apparatus.
