The lighting bus duct is suitable for the power supply
and distribution of fluorescent lamps, mercury lamps, and other lighting
equipment in various places with a current of less than 100A. It can be
combined according to different positions of the site, and the installation is
simple and quick. Within 1.5M of the branch line, it can supply power to two
sockets, and the insertion and removal are convenient. Under normal use
conditions, it can be directly inserted and removed, which is conducive to
maintenance. The system has the advantages of small volume, high strength, and
convenient installation. The copper conductor bus duct has good electrical
conductivity and thermal conductivity, good corrosion resistance and
weldability, and is easy to be processed by pressure. The aluminum conductor
bus duct has the characteristics of good electrical conductivity and thermal
conductivity, good corrosion resistance and weldability, small density, and
easy processing, and is used for various conductors, busbars, and
current-carrying parts of wires and cables.
The resistivity of the aluminum busbar is slightly
larger than that of copper, the electrical conductivity is inferior to that of
copper, the mechanical strength is smaller than that of copper, and it is easy
to be corroded and oxidized, but the price is cheap and it is lightweight. The
copper conductor bus duct has good electrical conductivity, small resistivity,
high mechanical strength, and good anti-corrosion performance, but the price is
relatively expensive. The conductors and overlapping conductors in the lighting
bus duct use T2 electrolytic copper as the conductor material, which is rolled
into TMY electrical hard copper busbars, and the purity of copper reaches more
than 99.9%, the conductivity is more than 97%, and the resistivity is
≤0.017777Ω•mm²/m. The shell and side plates of the lighting bus duct system are
made of high-quality aluminum-magnesium alloy materials, and the surface should
be treated with anti-oxidation treatment. The continuity resistance of the
shell protection circuit is ≤0.007Ω. All insulating materials use high-quality
polyester film, which is formed and wrapped throughout the whole length, with
no interfaces and no air bubbles in the middle. The insulation withstand
voltage is ≥3.75KV/1min, and the heat resistance grade is B level (≥130℃).
