Plug in bus duct conduction heat dissipation and daily maintenance

Release time:: 2022-05-21 Click count: 659

  Plug in bus duct can prevent overload and loss of fire.The insulation layer and outer skin of the cable will burn,and flame-retardant cables will also burn under flames.They only need to be separated by flames before they do not burn,and fire-resistant cables will not burn.Plug in bus ducts use both insulation and thermal insulation materials,so when laying power cables in cable trays,an additional 2 layers are allowed,taking into account heat dissipation issues.Plug in bus ducts use air conduction for heat dissipation and distribute the heat through a tightly connected steel casing.Therefore,compared to cables,the heat dissipation function of cables is generally average.

  Plug in bus ducts require almost no maintenance.Daily maintenance involves measuring the temperature rise of the casing and core bolts,as well as the temperature rise of the joints in the incoming box.If the core bolts are of grade 4.8,they need to be tightened on schedule.If high-strength bolts of grade 8.8 are used,they do not need to be stabilized on schedule.Plug in bus duct is a method of using plugs to connect the power supply of the main line to the branch line,making the connection very convenient.Plug in bus ducts in vertical shafts of high-rise buildings and residential areas require additional reserved plug interfaces to facilitate current branching.

  Factory workshops are allocated to each equipment or electrical unit,and it is also necessary to reserve plug-in interfaces.Bus ducts with plug-in units belong to plug-in bus ducts.Plug in busbar trunking belongs to the trunk system,which has the advantages of small volume,compact structure,reliable operation,high transmission current,easy tapping and feeding,convenient maintenance,low energy consumption,and good dynamic and thermal stability.It is widely used in high-rise buildings.The shell of the bus duct is generally formed by bending steel plates or using simple aluminum alloy profiles.Due to these two types of shells,there is no certain waterproof measure.

  During the fire extinguishing process or when exposed to rain,water is prone to enter the bus duct and cause a short circuit,resulting in a generally low waterproof rating of the entire product and poor product quality.The busbar trunking system is an efficient distribution device for transporting current,especially suitable for the economic and rational wiring needs of increasingly tall buildings and large-scale factories.As a traditional cable for power transmission,it can no longer meet the requirements in high current transmission systems.The parallel use of multiple cables has brought inconvenience to on-site installation and construction connections.Plug in bus ducts have emerged as a new type of distribution wire.
