Compared to the common ordinary bus ducts, dense bus ducts have multiple classifications. Let's take a detailed look at the advantages of each different dense bus duct and how to choose it in practical applications.

01 Ordinary dense bus duct

Adopting domestic methodsHeat shrink tubing, finely processed and assembled, with reliable insulation performance and a lifespan of up to 20 years. But it is not flame retardant, and this bus duct can be used as a distribution main for high load electromechanical equipment in ordinary multi story civil buildings.

02 Flame retardant dense bus duct

The copper busbar is wrapped with 3 layers of polytetrafluoroethylene film, and the power frequency withstand voltage can reach 3750V. After winding the busbar, imported PayChem or domestically produced ones are usedAs a protective sheath, heat shrinkable tubing is used to isolate the busbars between each phase using flame-retardant insulation sheets, with an oxygen index of 32 or above, achieving the electrical and flame-retardant performance of the busbar trunking.

03 Fire resistant dense bus duct

A special epoxy resin powder with high insulation performance and non flammability is sprayed on the busbar, and the accessories are fire-resistant insulation components. 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.

At present, dense bus ducts are widely used in the power supply and distribution of some enterprises, mining enterprises, and high-rise buildings. At the same time, in the power transformation of some old factory areas, dense bus ducts will also be re selected. Therefore, dense bus ducts play a very important role in the safe use of electricity in our modern life.
