How to choose the busway conductor - aluminum alloy cable rack

(Summary description)The busway conductor is copper or aluminum, and the service life of the busbar is critical depending on its operating temperature. The higher the operating temperature, the faster the aging rate (including copper, aluminum and insulation materials. Electrical copper and electrical aluminum for conductors, their creep strength, tensile strength and oxidation rate are closely related to temperature) . Because the busbars have different design and heat dissipation, the internal temperature is different. According to the conductor table of the design manual, the ambient temperature is 35 °C, and the dense busbar with better heat dissipation can reduce the current carrying capacity by 5%~15% to meet the temperature rise value of ≤70K. The dense busbar with poor heat dissipation should be reduced by 20%. About %, the air-carrying capacity of the air-type busbar is reduced more.

The strength of copper-aluminum composite interface directly affects its processing performance and reliability, and is the most critical performance parameter of copper-aluminum composite bus. No foaming when 90° bending, no obvious orange peel, no copper and aluminum layering when punching or shearing, can be used in electrical equipment, and meet the minimum requirements of interface bonding strength. The manufacturing process is different, and the interface bonding strength is different. With the heat exchange conduction technology used for the busway, the insulated conductor is in heat transfer contact with the outer casing, and a fully enclosed busway is created to meet the user's requirements. The special processing technology is used to form a hard copper composite cladding on the whole surface of the aluminum conductor. The mechanical and electrical properties can be equal to the copper conductor; the soft tin plating layer formed on the surface of the copper-aluminum composite further enhances the resistance of the conductor. Oxidation performance and power quality. The ultra-lightweight aluminum conductor will significantly reduce the cost of the product and reduce the basic investment in engineering projects. Reduce the weight of the product and reduce the installation strength for the majority of construction units. The busbars with better heat dissipation of the insulation material can meet the current-carrying requirements after being discounted according to the design manual or the electrician manual. However, some products of insulating materials are resin casting, or other insulating materials with poor heat dissipation, air-type busbar structure, and dense busbar structure with poor heat dissipation have more discounts.
