The conductive busbar that the new type of PZ PZCBT-I bus duct adopts uses 130 °C Mylar of degree B as the insulation medium, which up to the insulation effect for a long time. All the busbars adopt electrolytic copper of high purity as the conductive material . And the surface coating of the conductive and protective action , and reduces the contact resistance, the coating also participates the conduction, and effectively reduces the influence of skin effect. To suit the high requirements and good reliability that the distribution system required by the industrial buildings nowdays, the design of PZ ,PZCBT-I bus raises the high short circuit tolerance ,the whole system conforms to the UL three cycle and ASTA 1s/3s short circuit test standard. PZ,PZCBT-I bus duct has low voltage drop, and can reduce the consumption of the electric energy ,which will save your long-time investment .And its protective degree is IP65 .The whole aluminum alloy shell can eliminate the eddy effect caused in magnetic loop during the course of current .The conductive busbar is tinned ,which ensures the temperature rise of bus duct will not be 70°C higher than the environment temperature .The bus duct system has the total sealed shell protection, and the position of mounting will not influence the rated current value .Any position of the system can can keep 100% rated current capacity unchanged. This bus duct has the following advantages compared with the air bus duct system :1,It can greatly reduce the accident for the contact of bus duct; 2,It can prevent the dust accumulating in the outside of the bus duct through the ventilating duct;3,The inner is heat conduction, and it has good radiation effect
The bus duct system adopts the advanced integrated grounding mode, the grounding bus and the shell are connected together, it has 50% phase conductor capacity .When the high capacity grounding faults occur, it can be effectively grounded and protect the whole system.
