Abstract
The invention discloses an energy-saving compression type strain clamp. The clamp comprises an aluminum tube, a steel anchor, a jump line drainage terminal board and a bolt, and is characterized in that the steel anchor is used for connecting and anchoring a steel core of a steel core aluminium strand; then, the aluminum tube is sleeved; metal is plastically deformed through pressure; therefore, the clamp and a conducting wire are combined to form an integral body; the aluminum tube is formed by drawing an aluminum tube; the jump line drainage terminal board is formed by flattening the aluminum tube; the steel anchor is made of austenitic steel; and the austenitic steel comprises the following components according to percentage by weight: 21.5-25% of manganese, 3-5% of aluminium, 2-4% of chromium, 2-3% of vanadium, 0.14-0.2% of carbon, 0.2-0.3% of lanthanum-cerium complex rare earth, 0.5-0.8% of silicon, less than 0.05% of sulphur, less than 0.04% of phosphorus, and the balance of cast steel. According to the hydraulic strain clamp produced in the manner provided by the invention, all indexes satisfy the related specifications of the Nominal Failing Load Series and Coupling Dimensions for Electric Power Fittings of GB / T2315-2000 for electric power fittings; the product of the strain clamp has low energy consumption, which accounts for only 10-15% of that of the traditional clamp; and the clamp disclosed by the invention is superior to the traditional compression type strain clamp.
Description
technical field [0001] The invention relates to an electric power fitting, in particular to an energy-saving compression type strain clamp. Background technique [0002] As early as the 1940s, foreign countries began to conduct experiments and researches on fittings. The University of Manchester in the United Kingdom and the Ohio Brass Company in the United States conducted energy consumption comparison tests on ferromagnetic fittings and aluminum alloy fittings, and found that ferromagnetic fittings in the circuit Fittings are equivalent to a light bulb that is turned on day and night, and the annual consumption is astonishing, while aluminum alloy fittings basically have no energy consumption. In our country, it was not until the 1970s that the foreign party proposed the use of energy-saving fittings in the technical requirements of foreign-related power lines, which attracted the attention of relevant state departments. The National Electric Power Construction Research I...
