Abstract

The invention provides a strain clamp for an aluminum alloy core aluminum stranded wire. The strain clamp comprises a drainage plate 6, a drainage wire clip 7 which is connected with the drainage plate 6, a strain steel anchor 3, and an aluminum alloy tube 4 and a strain aluminum 5 which are orderly sleeved outside the strain steel anchor 3. Sleeve crimped parts are an anchor head 31 and a middle connecting part 32 of the strain steel anchor 3. One end which is not crimped of the aluminum alloy tube 4 is contained with a cavity for containing an inner core 1 of the aluminum alloy core aluminum stranded wire. One end which is not crimped of the strain aluminum 5 is provided with a cavity for containing a stranded wire 2. The middle part of the strain aluminum 5 is provided with the drainage plate 6. The aluminum alloy core aluminum stranded wire, the strain steel anchor 3, the aluminum alloy tube 4 and the strain aluminum 5 are coaxially arranged. The strain steel anchor 3 and the aluminum alloy tube 4 are pressed in advance. According to the strain clamp, mature hydraulic technology pressing is employed, the strain steel anchor and the aluminum alloy tube are pressed in a factory, the field construction is reduced, parts are few, an operation is convenient, the pressing quality is easy to be ensured, the corrosion resistance performance is good, high quality materials are selected, the installation is simple, the construction is facilitated, mechanical properties and electrical properties are good, and the quality is stable.

Description

technical field [0001] The invention belongs to the field of cable installation, and in particular relates to a strain clamp for an aluminum alloy-cored aluminum stranded wire. Background technique [0002] The wire tension clamp is a metal fitting that connects the wire to the tension insulator string. It is used to fix the wire to bear the tension of the wire, and it is also used as a conductor to conduct current. It is an important fitting in the transmission line. [0003] The United States began to use aluminum alloy materials as conductors in 1921. Due to its high strength, light weight, and good electrical conductivity, the research and application of aluminum alloy overhead wires has a history of decades. But our country has been using steel-reinforced aluminum stranded wire. With the vigorous development of my country's electric power industry, we have a deeper understanding of the advantages and economic effects of aluminum alloy wires. In recent years, with the i...
