Embodiment Construction

[0016] The claimed subject matter is described with reference to the drawings, wherein like reference numerals are used to refer to like parts throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to understand the claimed subject matter. It may be evident, however, that claimed subject matter may be practiced without these specific details.

[0017] The present disclosure relates to a spacing damper, which is generally used to space split electrical conductors suspended from transmission towers, transmission racks or transmission poles. In particular, the present disclosure relates to a clamp arm gasket or bushing for use in the cable spacer clamp arms of such spacer dampers or other cable securing and support devices.

[0018] Overhead transmission lines typically operate at voltages in the range of 275kV to 400kV and can operate at voltages as high as 600kV. At the above voltages, it is important to design ...

Abstract

A gasket for use with a cable spacer grip arm is provided. The pad includes a first portion of arcuate configuration and made of a first elastomeric material. The second portion is of arcuate configuration and is receivable within the first portion. The second part is made of a second elastomeric material different from the first elastomeric material. The first part is connected to the second part.

Description

technical field [0001] The present disclosure generally relates to cable spacer clamp arms. In particular, the present disclosure relates to a gasket that provides cushioning between a conductive cable and a spacer clamp arm. Background technique [0002] High voltage overhead power transmission or distribution systems typically have a number of conductive cables. Spacer clamping arms are used to reduce the possibility of conductive cables touching each other, reducing corona discharge and the generation of electrical stress and interference. The spacer clamp arm has an elongated arm portion and a cable retaining end portion at one end of the arm. The spacer clamp arms clamp respective conductive cables at the retaining end portions. The other end of the spacer clamp arm is connected to a frame to which one or more additional spacer clamp arms may be attached. The spacer clamp arms allow a limited amount of movement of the spacer clamp arms relative to the frame and prov...
