High-quality copper and aluminum transition plate, bending, punching copper and aluminum transition plate

Use for power plants and substations copper transition connecting bus and aluminum bus. MG main types of copper and aluminum ... copper and aluminum busbars meaning MG-- transition board. Type in the letters and numbers meaning: M-- bus; G-- transition; digital - plate size (width × thickness, mm2) 3.MG copper and aluminum transition board structure and the main parameters of existing copper and aluminum transition structure diagram. by butt plate connected by copper and aluminum, the presence of a large quantity of copper consumption, poor performance and manufacturing process complexity and other issues. This article will be changed to end the current product-sided copper (1 ~ 2mm thick) copper and aluminum transition board, with 10% to 20% (the existing products to meet the conductivity requirements, breakable joints overcome defects and copper consumption was only by weight) and so on. The new electrical fittings use the parallel explosion welding, its electrical properties (such as contact resistance, temperature) in line with the national standard GB2137-85 and GB2314-85. For the shortcomings of traditional copper and aluminum transition plate, copper and aluminum equipment, clamp in production and use, and put forward the corresponding two new transmission lines with the production process - explosion-welded copper and aluminum welding transition board and embedded copper ring type copper aluminum equipment clamp. Its electrical properties were tested, the results show that not only saves copper, and the process is simple, electrical performance in line with the national standard, should be introduced. (Copper and aluminum transition plate) raw material copper: t2y (copper content of 99.9%) aluminum: l2 (aluminum content 99.9%) (2) Implementation of standards: gb5585.2-85 gb / t1196-93 (3) welding performance welding: high temperature diffusion welding, casting welding, resistance welding, welding. Welding performance: firm, uniform, smooth, no cracks, no Weld, no bubbles, small temperature rise, the pressure is reduced. (4) conductivity Resistivity: ≤0.0012ω / m carrying capacity per unit area: 4a / weld temperature: <80 ℃ drop: <3mv (5) Strength: Tensile strength: 240mpa, torsional strength 150mpa (not lower than the strength of the base material of the same species) (6) Soft connection stretchable soft connection can take every piece CNC punching machine copper material, the poor can ensure every piece of copper sheet of absolute balance, an accuracy of 0.0001mm, not presence due to uneven squeeze between cutting each piece together, and fully guarantee the role of soft elastic connection is not limited. (7) connecting the ends of making soft soft-wired copper ends is a one-time high-temperature diffusion welding welded (unlike ordinary soft connection with copper connection), no attachment welds, the soft connection itself no temperature rise and drop problem.
