1. The tubular bus is in the form of a split-phase fully insulated shielded copper tube bus.
2. The cylindrical capacitor structure is selected, and the voltage equalizing capacitor layer, the main insulation layer, and the bottom layer of the shielding street are set between the conductor and the insulating sheath, and the shielding grounding layer on the outside is connected to the grounding grid. The quantity of each tier is confirmed by the seller based on the existing successful experience. The principle of setting is to make the electric and magnetic fields of the tube bus uniform and the surface point of the tube bus bar to zero.
3. The conductor is an oxygen-free copper tube with a purity of not less than 99.99%.
4. The uniform capacitance layer is made of semiconductor paper and semi-coated.
5. The shielding grounding layer is half-coated with copper foil, and the thickness is not less than 0.05mm. It is necessary to reinforce the grounding point.
6. The grounding lead is made of copper wire, and the useful cross-sectional area is not less than 6mm2.
7. The main insulating material is solid insulating silica gel or PTFE oriented film.
8. The insulating sheath of the grounding layer should be able to reliably avoid the intrusion of moisture and moisture. Heat-shrinkable insulating sleeves can be used, and their color should be the same as the color (A yellow, B green, C red). Two layers of heat shrinkable insulating sleeve are selected, the total thickness (shortened) is not less than 3mm, the joint (if any) is necessary to be staggered, and the lap length of the joint is not less than 100mm.
9. The large span of the suspension shall not exceed 6m.
10. Conductor appearance requirements: the end of the copper tube should be rounded, and the connecting surface of the end of the copper tube should be silver-plated or tin-plated to ensure low contact resistance and anti-corrosion function.
11. Terminal joint requirements: the two ends of the purple weave are pressed with copper end plates, the end plates are lubricated, the appearance is lubricated, and there are no edges and corners. It is necessary to have a current margin of 150% of the rated value for the conductive plate. The temperature rise of this part is lower than the conduction body temperature rise, and a sampling test should be done before leaving the factory.
12. Grounding requirements: it is necessary to be reliable grounding at the bottom of the all-phase insulated copper tube bus street, including the shielding insulating sleeve at the central joint, and the grounding mode is one point grounding (each section can be grounded independently) to avoid the grounding of the insulated copper tube bus wire at multiple points, and the circulation current occurs, so as to ensure that the external grounding layer meets the requirements of human safety contact; It is also necessary to reliably ground the metal outer sheath, if any.

Rectangular busbar, trough busbar, and tubular busbar analysis
The rectangular bus has good heat dissipation performance and is easy to fix and connect. But its skin effect is quite large. In order to reduce the skin effect, the cross-sectional area of a single busbar should not exceed 1250 square millimeters. When the working current exceeds the promised current of a single bus, 2 to 4 rectangular buses can be used. Rectangular conductor a ...
