ASSEMBLY COMPONENT OF COMPRESSION TYPE ANCHOR CLAMP, ANCHOR STRUCTURE OF POWER-TRANSMISSION LINE AND METHOD OF CONSTRUCTING COMPRESSION TYPE ANCHOR CLAMP
An assembly component of a compression type anchor clamp includes: a housing tube that houses an end portion of a core portion of a power-transmission line; a core portion compression member, made of steel, that includes a housing hole to house the end portion of the core portion and the housing tube and is to be compressed with the core portion and the housing tube; and a conductive portion compression member, made of pure aluminum or an aluminum alloy, that houses an end portion of a conductive portion of the power-transmission line and the core portion compression member and is to be compressed with the conductive portion and the core portion compression member, wherein the housing tube is constituted by pure aluminum or an aluminum alloy whose Vickers hardness Hv is less than or equal to 30, and continuously provided in its cylindrical direction without a gap.
Multi-layer cable splice
A cable splice includes a casing having a central portion and a first end including a first aperture. The casing defines an interior cavity. A guide assembly extends through the first opening into the interior cavity. A first clamp member is positioned in the interior cavity and moveable between a loading position and a terminated position. A first biasing member biases the first clamp member toward the terminated position. A carrier is positioned in the interior cavity between the first biasing member and the central region. A second clamp member is positioned in the carrier and moveable with respect to the carrier.
