What should be done if the temperature of the dense bus duct is too high?If the temperature of CESKO bus duct is too high,it will cause power failure.In order to use the bus duct safely,it is necessary to first understand its cooling method to avoid the impact of high temperature on the bus duct.Below,Guangdong Cisco General Electric will explain what to do if the temperature of the bus duct is found to be too high?

　　Low voltage transmission line conductors,cables,cables,branch dense bus ducts,bare conductors,punctured cables,etc.Due to the different heat dissipation performance of different products,the load-bearing capacity also varies per square millimeter.When the same product and wire of the same specifications pass through the same current,the heat dissipation performance will also change when the temperature rises;Due to the design of different cross-sectional areas,the temperature rise is also different.Of course,as the temperature rises and the resistance increases,the pressure increases and energy loss increases.

　　The installation of dense bus ducts with dedicated lanes must be measured on site,and the length requirements for installation are very high.The height of the plug-in switch box for dense bus ducts should also be determined according to the design.When laying fire distribution lines in the dark,they should be laid in non combustible structures,and the thickness of the protective layer should not be less than 30mm.When using transparent laying,metal pipes or metal cable trays are used to protect the fireproof coating,as metal pipes and metal trays themselves do not have fireproof performance.When insulated and sheathed cables are not made of flame-retardant materials,metal conduit and metal trunking protection may not wear out on the shaft,but the wiring must pass through board conduits and grooves to protect the upper and lower end wires from passing through the shaft floor.The gaps between pipelines and grooves should also be sealed and sealed.Therefore,the GB7251-2006 standard stipulates that the rated current limits the temperature rise to determine the current carrying capacity and strengthen the bus duct.

　　The dense bus duct is the same.Therefore,calculating the conductors of dense bus ducts based on the flow rate per square millimeter is incorrect.Structural design and heat dissipation,but different impedance,inductance,and other factors are closely related to current carrying capacity.
