1. Reliable insulation method
There is an insulating layer on the conductive bar, and there is a certain air yard between the phase and the phase, and there is an insulating pad block limited by DMC data between the conductive bar and the shell, and the triple insulation ensures that the insulation of the bus duct is full of certainty, especially in the humid environment.
2. Strong anti-corrosion
The aluminum profile shell has a much better galvanized anti-corrosion function after anodizing 10u, which is much better than the steel shell Japan's long-term atmospheric exposure experiments on different grades of aluminum alloy plates and galvanized copper plates, showing that its corrosion depth is about two ^ of the latter.
3. Reinforced aluminum alloy shell planning
The shell is made of aluminum-magnesium alloy profile, which is made of two side plates and upper and lower cover plates, and the side plate is planned with heat sink and dovetail groove, which is not only conducive to the heat dissipation of the bus duct, but also strengthens the rigidity of the shell, and also facilitates the safety and reduces the weight of the bus duct at the same time, and can plan and reduce the device bracket in a large span.
4. All grounding skills
The traditional PGA wire is placed on one side of the bus duct, because the fault current induced by electromagnetic induction on the PGD is 50% higher than the calculation of the actual measurement, and the three-phase conductive row is unequal to the PE spacing, and the inductance is unequal.
The non-magnetic material aluminum alloy shell with excellent conductivity function is selected as the protective ground wire, surrounded by the conductive bar, because it is as close as possible to the three-phase busbar, the reactance ^ is small, and the interval between the protective ground wire and the three-phase bus bar is equal, and the reactance is the same.
In this way, whether it is a short-term or a continuous short circuit to the ground, this and the grounding method are better than setting the E-row alone. Therefore, the World Electrical Skills Council issued and sold a wire transfer (busway) with a shell as the grounding conductor.
5. The device is convenient
Because the full-length appearance scale is the same, the internal structure is symmetrical, and it can be arranged as L1, L2, L3, N on either side, so the inversion is very simple and the device is convenient.
