Abstract

The utility model relates to an aluminum alloy core aluminum stranded wire strain clamp, which comprises a steel anchor, a high-strength aluminum alloy strain main body and a drainage wire clamp. The strain clamp is characterized in that the high-strength aluminum alloy strain main body and an aluminum alloy core aluminum stranded wire are crimped; a steel anchor ring turn groove and the high-strength aluminum alloy strain main body are crimped and connected; and the high-strength aluminum alloy strain main body is connected with the drainage wire clamp with a dual-plate structure by adopting a drainage plate with a special I-shaped cross section structure. The utility model ensures the strength demand of the strain clamp by adopting the high-strength aluminum alloy strain main body; the steel anchor with a special structure is adopted, the structure of the steel anchor is different from the conventional structure, the high-strength aluminum alloy strain main body and the aluminum alloy core aluminum stranded wire are crimped and then the steel anchor ring turn groove and the high-strength aluminum alloy strain main body are crimped and connected, thereby ensuring the crimping quality; the high-strength aluminum alloy strain main body is connected with the drainage wire clamp with the dual-plate structure by adopting the special I-shaped cross section structure, and thereby, the fatigue resistance and the electric property of the drainage part of the strain clamp are ensured and the running safety and reliability of an aluminum alloy core aluminum stranded wire line is improved.

Description

Aluminium alloy core aluminium stranded conductor strain clamp

Technical field

The utility model relates to a kind of used for transmission line strain clamp, is that to adopt the aluminium alloy core aluminium stranded conductor in electric power system be the strain clamp of using in the transmission line of lead specifically.

Background technology

Along with greatly developing of China's electric utility, the aluminium alloy core aluminium stranded conductor begins to use because of the high efficiency and the energy saving of its power transmission efficiency.But because aluminium alloy core is different with the material of steel anchor, aluminium alloy core and the direct crimping of steel anchor exist aluminium alloy core to be crushed disconnected strand hidden danger of quality in advance, make the fail safe of transmission line and reliability can not get guaranteeing.Simultaneously, common drainage way often causes that the drainage part of strain clamp causes the fracture of drainage plate because of vibrating fatigue.

The utility model content

The purpose of this utility model provides a kind of aluminium alloy core aluminium stranded conductor used for transmission line strain clamp, mainly be in order to solve the crimp quality that the aluminium alloy core aluminium stranded conductor links to each other with the strain clamp crimping, and the anti-fatigue performance of strain clamp drainage part, thereby improve the security reliability of aluminium alloy core aluminium stranded conductor transmission line operation.

For achieving the above object, the utility model provides a kind of aluminium alloy core aluminium stranded conductor strain clamp, comprise steel anchor, high-strength aluminum alloy strain insulator main body, drainage wire clamp, it is characterized in that: high-strength aluminum alloy strain insulator main body one end and the crimping of aluminium alloy core aluminium stranded conductor, the other end and the crimping of steel anchor ring circle groove, high-strength aluminum alloy strain insulator main body adopt " worker " font section structure drainage plate to link to each other with the drainage wire clamp of double plate structure.

The utility model adopts high-strength aluminum alloy strain insulator main body and the crimping of aluminium alloy core aluminium stranded conductor, steel anchor ring circle groove is linked to each other with the crimping of high-strength aluminum alloy strain insulator main body again, has guaranteed crimp quality; High-strength aluminum alloy strain insulator main body adopts special " worker " font section structure to link to each other with the drainage wire clamp of double plate structure, guarantee the anti-fatigue performance and the electric property of strain clamp drainage part, improved the security reliability of aluminium alloy core, aluminium skew-wire line operation.
