Plug in bus ducts do not require the installation of built-in smoke screens.After processing,they are coated with high-quality insulation materials,which are flame retardant and have good insulation performance.The conductive busbar of the plug-in bus duct uses electrolytic copper as the conductor,and the conductive busbar is tightly installed in the shell without any gaps,and is completely insulated with a halogen-free polyester sheath.The shell of the plug-in bus duct is made of aluminum alloy material with heat dissipation fins,which has good heat dissipation function and energy-saving effect.It has high performance under extreme conditions such as voltage drop under current and long distance.

　　The plug-in bus duct can meet the needs of outdoor use and places with sprinkler water.The aluminum alloy shell serves as a PE line as a whole,and the cross-sectional area of the aluminum alloy shell is greater than 70%of one phase line.Plug in bus ducts can withstand strong electrical forces and have good heat dissipation performance,greatly improving their load capacity.The shell structure design is formed by a molding machine,giving it extraordinary support strength,which can ensure a pressure of 70 kilograms along the center of the 6m busbar connection,with a span of no more than 15mm,solving the problem of being unable to support lifting during large-span installation.

　　Plug in bus duct has good dynamic and thermal stability,small size,good heat dissipation,low temperature rise,space saving,low voltage drop,and reduced energy loss,suitable for the transmission of high-power currents.The busbar mainline system for power transmission and distribution is very suitable as a connection between transformers and distribution panels or between distribution panels,or as a major current distribution device for industrial,commercial,and service industries in the distribution room.The rated current of the busbar trunking system is between 630A and 5000A.The outer shell of the busbar is extruded from aluminum alloy,which gives the product high mechanical resistance and reduces weight.

　　The connection of plug-in bus ducts to various voltage distribution devices in substations,as well as the connection of electrical equipment such as transformers and corresponding distribution devices,mostly uses bare or stranded wires with rectangular or circular cross-sections.The function of the bus is to collect,distribute,and transmit electrical energy.Due to the large amount of electrical energy passing through the busbar during operation,the plug-in busbar slot bears significant heat and electric force effects during short circuits.Therefore,it is necessary to select busbar materials,cross-sectional shapes,and cross-sectional areas reasonably to meet the requirements of safe and economical operation.
