Dense busbars can provide convenience for projects with high power consumption, so what kind of busway is a good one? Next, the bus duct manufacturer will teach you how to choose a good bus duct from three aspects.

1. Pay attention to the conductor material of the busbar: currently, there are mainly three types: copper busbar, aluminum busbar, and copper aluminum composite material. The price difference is significant. In addition to purity, attention should also be paid to the mechanical properties of the material after bending. Here, we will focus on introducing copper aluminum composite materials. The strength of the copper aluminum composite interface directly affects its processing performance and reliability. It is a key performance parameter of copper aluminum composite busbar. 90 ° bending without bubbles, no obvious orange peel phenomenon, and no copper aluminum delamination during punching and cutting. Can be used for electrical equipment to meet low requirements for interface bonding strength.

2. Choose qualified products from legitimate enterprises: Bus ducts should use products with 3C mandatory certification marks and type test reports. When making purchases, it is necessary to thoroughly investigate the manufacturer's production scale, technical strength, worker quality, and production environment, especially the production environment. Because if insulation treatment is carried out in an unclean space, there will be some conductive particles in the insulation layer. It doesn't matter in the early stages of operation, but over time it can cause insulation damage.

3. Choose an economical busbar section: Generally, the busbar section should be selected based on the long-term operating current. And check the short-term thermal stability and dynamic stability of the bus duct when passing through a large short-circuit cable. Due to factors such as the resistance of conductors and the metering effect of alternating current when multiple conductors are in close proximity, bus ducts generate heat when current passes through them. The allowable heating temperature for copper aluminum bare busbars during long-term operation is 70 ℃, but when the contact surface is reliably tinned (such as ultrasonic tin plating, etc.), the temperature is allowed to rise to 85 ℃ and continue to be heated. Due to temperature limitations, busbars of different materials and cross-sections are given corresponding long-term allowable current values. When selecting a busbar cross-section, the actual long-term operating current of the busbar should be less than the long-term allowable current value of the selected cross-section busbar.
