Dead-end clamp for supporting expanded diameter conductors

Abstract

The invention provides a dead-end clamp for connecting supporting expanded diameter conductors on poles and towers of an airy route for power transmission and a converting station, comprising a dead-end aluminum tube 8, a dead-end steel anchor 7, an aluminum liner tube 6 and a jumper conductor clamper 9, wherein the aluminum liner tube 6 is used for replacing one part of a high-density polyethylene support layer 3 of a supporting expanded diameter conductor 1, and the dead-end aluminum tube 8 is crimped on an outer-layer aluminum wire 5 and the aluminum liner tube 6. The dead-end clamp is suitable for the supporting expanded diameter conductors and stable and effective gripping supporting conductors and has simple structure and stable and reliable construction process.

Description

technical field [0001] The invention belongs to the field of electric power system fittings, and in particular relates to a strain clamp for connecting a support-type enlarged-diameter conductor on an overhead power transmission line and a pole tower of a substation. Background technique [0002] The wire tension clamp is a metal fitting that connects the wire to the tension insulator string. In addition to bearing all the tension of the wire, it also conducts current as a conductor and is an important fitting in the transmission line. The UHV project aims to build an "environmentally friendly" project, comprehensively optimizes the design of the project, and strictly ensures that the electric field, magnetic field, audible noise and radio interference levels meet the standard requirements. For this reason, if the design uses ordinary wires, it is necessary to increase the cross-section of the wires and increase the number of split wires, which will inevitably increase the u...

[0003] High-density polyethylene supported expanded-diameter wire is a new structural form of wire invented in my country, such as figure 1 As shown, this kind of support type expanded diameter wire includes a steel core 2, and the outside of the steel core is wrapped with a high-density polyethylene support layer 3, an inner layer aluminum wire 4 and an outer layer aluminum wire 5 in sequence. With this kind of wire, the strain-resistant aluminum tube will be directly crimped to the wire. Since the high-density polyethylene support layer 3 usually cannot be directly crimped into the metal, even if the high-density polyethylene support layer 3 is directly crimped to the metal steel core In 2, a good and stable grip cannot be obtained, and there will be serious safety hazards
