GFM series enclosed Busbar Bus Barand insulated rectangular Busbar Bus Bar (3-35kv / 250a-5000a) is a new energy-saving product promoted by our company according to the market demand.The products are widely used in power plants, iron and steel companies, hydropower stations, thermal power stations between the high voltage distribution cabinet, transformer low voltage side and the distribution cabinet, as well as in the transmission and distribution lines of generators.



Main features:

●shell:made of non-magnetic high-quality aluminum alloy plate, completely closed structure, with good corrosion resistance and excellent heat dissipation performance.The non-magnetic enclosure can greatly reduce the eddy current heating caused by high voltage current.Reduce the temperature of closed bus shell, reduce the loss of electric energy, increase the carrying capacity and reduce the electric power.
● the conductor is rectangular bus, tube bus, material can use copper and aluminum.
● special flange mouth design, so that the larger bus box can be flexible assembly.The design and installation of bus system can be simplified, programmed and standardized.
● each bus generally in the upper part of the reasonable access hole, maintenance personnel can therefore operate to any position inside the bus.The inspection port adopts bending flanging process and high-demand welding process to make the protection grade of bus system shell reach IP54.
● for large current indoor closed Busbar Bus Bar there are ventilation Windows on both sides and the bottom of the shell to strengthen heat dissipation and reduce temperature rise.
● drainage: close the bottom of the bus set drainage device to prevent internal water.
● grounding: the grounding terminal is designed for the end flange of each bus. After the installation of the bus, the whole grounding is completed.
