(2) Good heat dissipation condition and low temperature rise
The hV insulated tubular bus is hollow conductor, and the inner diameter air duct of the bus can form hot air convection in the application of naturally insulated copper tubular bus in the new project, so the heat dissipation condition is better.
(3) Large section coefficient and high mechanical strength
Because the conductor adopts the tubular shape, its section coefficient is large, the mechanical strength is high, may adopt the long span arrangement, simultaneously reduces the busbar support member number.In 50 k A short-circuit current situation, Φ 100 x 5 mm copper bus bar suspended span up to 9 meters, using the bus bracket support, busbar span can be up to 13 meters.
(4) Strong electrical insulation performance
Hv insulated tubular bus adopts sealed shielded insulation mode, and the ground potential of the housing is zero.The shielded insulated tubular bus has uniform electric field distribution, strong electrical insulation and good weather resistance.
(5) Strong earthquake resistance and simple installation
The hV insulated tubular bus can be fixed directly on the steel structure frame or concrete support, and the wall cover and post insulator can be removed, which has strong anti-seismic capability.The bus structure is simple, the layout is clear, the installation is convenient, and the maintenance free operation is realized.
(6) The Semi-insulated aluminum tube busbar has heat resistance, aging resistance and high insulating performance
The main insulating material of hV insulated tubular bus adopts polytetrafluorethylene, which can work in -250℃~+340℃, has excellent electrical performance and chemical stability, small dielectric loss, flame retardant, anti-aging and service life ≥30 years.
(7) Free from environmental interference, high reliability and small maintenance workload
Hv Semi-insulated aluminum tube busbar is enclosed and insulated, with no condensation inside, and eliminates the influence of moisture, dust and other factors outside, with high reliability.Hv insulated tube bus adopts single machine seal and shield insulation, reliable grounding, can completely avoid all short circuit fault, has high reliability, and maintenance amount is small
Bus structure simple, clear layout, easy installation, less maintenance work.
Product installation is successful, lifetime maintenance free.
