What is the Processing Standard and Function of Copper Soft Connection？

Copper soft connection, the interface adopts molecular diffusion welding technology to be welded at one time. Shaanxi Joyelectric copper soft connection products are of good quality, strong conductivity, high current resistance, low resistance and durable. Copper flexible connections are widely used in power stations, generators, transformers, power transmission and distribution, switch cabinets, bus ducts, industrial electric furnaces, electrolytic smelting, welding equipment, rectifier equipment and other scenes.

The copper soft connection supplied by Joyelectric uses T2 red copper as the copper material, which has the following characteristics:

1. T2 or T2M or oxygen-free copper tape, the thickness of the copper foil is between 0.05mm~0.5mm.

2.The lap surface is tinned or silver plated.

3. The product can process various non-standard soft connections according to user requirements.

4. The user's material processing, the overlap of the inch: length 220mm, width 440mm, thickness 40mm, the total length is not limited. Pressure welding soft connection pressure welding is to press the copper foil laminated parts together, using molecular diffusion welding, through high current Heating pressure welding forming. Copper foil: 0.05mm to 0.5mm thick. The contact surface can be tin-plated or silver-plated according to user requirements. Brazing soft connection Brazing is to press the copper foil laminated parts together, using silver-based brazing material, and butt welding with flat copper blocks. Copper foil: 0.05mm to 0.5mm thick. The contact surface can be tin-plated or silver-plated according to user requirements.

A few explain on pressure welding/brazing: In order to ensure the flatness of the contact surface, customers can provide special widths, lengths and drill holes, which can be processed according to user requirements. The allowable ampacity is a reference value. This value is related to the installation and use conditions of the soft connection.

Processing standards for copper bars

1.Appearance quality:

Finished copper and copper alloy bus bars are not allowed to have joints, and the surface quality should be smooth and flat, and there should be no defects that are not commensurate with good industrial products; the gap between the shear blade and the die and the folding must be selected according to the thickness of the copper bar The radius of the bend fillet. There should be no flashes, burrs and cracks at the rounded corners and edges of copper and copper alloy bus bars. The narrow side size is 10-20, the wide side size is 60-200mm, the delivery length is generally 2-9m, and the delivery quality is about 40-100kg.

Chemical composition:

Baidu Sampling: Select representative parts, the tissue composition of the sample is uniform, and the sample should be clean before preparation, free of rust, dirt and other debris. If necessary, the sample can be cleaned with ether and acetone , Rinse with alcohol, and then dry. Sample scraps can be drilled, but it is necessary to prevent the introduction of impurities, especially iron, and the speed of the sample is controlled to prevent overheating and oxidation.

The role of copper bars

Copper bars are used as bus bars in high-voltage switch cabinets, as well as the power transmission medium between switches and contacts. The copper bar connects all charged bodies together to form a closed power distribution circuit. Low-voltage switch cabinets also use copper bars. When the line current is small, aluminum bars are also used instead of copper bars.

Brazing soft connection of copper bars

Brazing is to press the laminated parts of the copper foil together, using silver-based brazing material, and butt-welding with the flat copper block to form. Copper foil: 0.05mm to 0.5mm thick. The contact surface can be tin-plated or silver-plated according to user requirements.
