The dense busbar trunking is finely processed and assembled using heat shrink tubing,with reliable insulation performance and a lifespan of up to 20 years.Dense busbar trunking can be used as the main distribution line for high load electromechanical equipment in ordinary multi story civil buildings.Special epoxy resin powder with high insulation performance and non flammability is sprayed onto the busbar,and the accessories are fire-resistant insulation components.Low voltage distribution main lines such as fire pumps,fire elevators,and emergency generators should use fire-resistant dense bus ducts to ensure power supply in case of fire and facilitate the elimination of the fire.

　　Specially designed and processed parts such as busbar connectors,plug-in boxes,and busbar trunking shells have fire resistance performance that meets fire resistance standards.The dense busbar trunking adopts intelligent monitoring devices throughout the entire process to fully grasp the system operation status and ensure the safe operation of the power supply system.The bus duct comes with a built-in measurement and control cable duct,making installation convenient.Fully enclosed structure,good sealing of the shell,with a protection level of IP65,can adapt to any harsh installation site.The shell also serves as a grounding PE wire,with good grounding effect and safe use.The busbar has a low temperature rise,low energy consumption,and strong current carrying capacity,which can greatly reduce investment costs.

　　What are the impacts on the service life of dense bus ducts in the power system?With the increasing demand for electricity in the power industry,the installation of bus duct electrical equipment can provide a guarantee for the power industry.Temperature is a key factor affecting the lifespan of dense bus ducts.If the temperature in the workplace of the bus duct is too high,the insulation layer is prone to aging.Once the insulation is completely damaged,the performance of the bus duct will be affected and safety will not be guaranteed.Continuing to use it at this time is unreliable.

　　The temperature rise at the connection of the bus duct must be below 60℃,so it is necessary to control the ambient temperature as much as possible within this range.Humidity can also affect the service life of equipment,especially metal busbar trunking electrical equipment.Metal is prone to rusting when exposed to moisture.If it works in a high humidity environment for a long time,once it corrodes and rusts,the performance of dense bus ducts will also be affected,and in severe cases,it may cause safety accidents.There are many key points to the use of dense bus ducts,and improper operation can also damage the lifespan of the bus ducts and their accessories.
