The invention relates to a tinned strip-shaped copper bar, which belongs to the technical field of electrical alloy materials. It includes a copper bar body (1), the copper bar body (1) has a strip-shaped special-shaped structure, and the left and right side walls of the copper bar body (1) are respectively set as a first concave-convex surface (11) and a second concave-convex surface ( 12). The invention can be applied to occasions that have special cross-sectional shape requirements for conductor materials. Therefore, it meets the needs of product upgrading in the electrical industry. And a layer of metal tin (2) is plated on the surface of the copper bar body (1), which can increase the conductivity of the copper bar.
Description
(1) Technical field [0001] The invention relates to a copper bar for electricians. Mainly used in medium and low voltage switchgear, busbar system, transformer, railway, wind power, nuclear power and hydroelectric generator, etc. It belongs to the technical field of electrical alloy materials. (2) Background technology [0002] Copper bars for electricians are conductor materials for installation of medium and low voltage switch cabinets, busbar systems, transformers, railways, wind power, nuclear power and hydroelectric generators. The traditional copper busbars for electricians have the following deficiencies: [0003] 1. Its cross section is rectangular. Rectangular copper bars can only be used as conductor materials for general electrical products, but not suitable for some occasions that require special cross-sectional shapes for conductor materials. Therefore, it cannot meet the needs of product upgrading in the electrical industry. [0004] 2. The copper bar is m...
