Low voltage enclosed aluminum shell bus duct

Low voltage enclosed aluminum shell bus duct

Structural features: The bus duct shell is made of cold pressed track aluminum alloy profiles, which are easy to assemble and have a beautiful appearance. Adopting a separated air insulation type, the net distance between phases and between phases and ground is much greater than the standard requirements, making it extremely safe and reliable. The internal insulation components are made of high-strength epoxy resin material, which improves the resistance and dynamic thermal stability of the bus duct. The joint adopts a docking connection method and uses double connected copper bars, effectively increasing the contact area of the joint and making installation convenient and fast. There are many standard parts and inventory for bus ducts, which can be shipped quickly and save on-site work time. Bus duct tightly connected“sandwich”Structures can reduce electrical space, freeing up more space for commercial purposes such as renting or as public spaces. For installing cables, it is a difficult task. Because a single cable is often heavy, installation work requires the cooperation of many people and takes a lot of time to complete. In addition, due to the bending radius of the cable, more installation space is required.

All weather product, capable of operating in an environment of minus 40 ° C for extended periods of time, with insulation resin that does not crack. No metal shell, resistant to various chemical corrosion, working in environments with stray currents, will not cause electrical corrosion of the shell. Waterproof function, can work in water for a long time, can be used in cable trenches, and can also be buried underground. The enclosure protection level is IP68, which is not only water-resistant, fire-resistant, and corrosion-resistant.

The shell is made of reinforced molded aluminum magnesium alloy profiles for electrical use or a mixture of molded aluminum alloy integral side panel profiles and cold drawn steel cover panel profiles for electrical use.

At present, there are mainly three types: copper bars and aluminum bars, and copper aluminum composite, with significant price differences. In addition to paying attention to its purity, attention should also be paid to the mechanical properties of the material after bending. Here, we will focus on the copper aluminum composite, bus duct, and the interface strength of copper aluminum composite, which directly affects their processing performance and reliability, and are the key performance parameters of copper aluminum composite bus. When bending at a 90 ° angle, there should be no bubbles or obvious orange peel, and there should be no copper aluminum delamination during punching and shearing. Only by sealing the bus duct can it be used in electrical equipment and meet the lower requirements for interface bonding strength. The interface bonding strength varies depending on the manufacturing process. When copper and aluminum are pressed and combined by mechanical pressure, only atomic bonds can be formed at the interface atoms. After heat treatment and diffusion, point bonding becomes surface bonding, but the diffusion depth is thin and the interface bonding strength is not high. Processing under specific process conditions to fuse copper and aluminum is necessary to form a composite layer with uniform interface bonding and a certain thickness, achieving high interface bonding strength.

Low voltage enclosed aluminum shell bus duct

1. In terms of performance, the busbar adopts copper or aluminum bars, which have high current density, low resistance, and small skin effect, and do not require derating. Low energy loss, Xianning busbar trunking ultimately saves users' investment.

2. The metal enclosed shell of the safety bus duct can protect the bus from mechanical or animal damage. The installation of plug-in units in the distribution system is very safe, and the shell can be grounded as a whole, which is very reliable.

3. In terms of installation, the busbar consists of many sections, each of which is short and light in length. Therefore, only a few people are needed to quickly complete the installation. There are many standard parts and inventory for busbars, which can be shipped quickly and save on-site work time. Its tight "sandwich" structure can reduce electrical space, freeing up more space for commercial purposes such as renting or as public spaces.

The installation of busbar trunking is relatively simple, but there are many places that need attention (1) When installing the dense bus duct horizontally, each installation unit should have no less than 2 brackets, and the brackets should be stable and firm (2) When installed vertically, the bracket must be firmly secured to prevent shaking. The quotation for the high-voltage bus duct, especially at the plug-in interface, requires maximum force when inserting the power box to prevent shaking of the bus duct (3) The bus duct and bracket are connected by compression (4) Every time a bus duct is installed, the insulation resistance between phases, phase to ground, phase to zero, and zero to ground must be measured. The insulation resistance must be greater than 20 megaohms (5) Each end of the bus duct is intact without deformation, damage, or foreign objects entering (6) According to the construction situation, installation can start from the power end or the load end (7) Connect the connector head, do not use external force to violently impact installation, use the self gravity insertion of the bus duct, install horizontally steadily, and insert horizontally by dragging and pulling
