Classification of dense bus ducts in Suzhou

Hello everyone! Welcome to this article! I am the editor of a Suzhou intensive busway manufacturer, and I am very happy to share with you what we have today: the classification of Suzhou intensive busway.

There are many types of bus ducts. The classification of Suzhou dense bus ducts is as follows:

Ordinary Suzhou dense bus duct: Ordinary Suzhou dense bus duct adopts domestic heat-shrinkable tubing, fine processing and assembly, reliable insulation performance, and a service life of up to 20 years. But it is not flame-retardant. Ordinary Suzhou dense bus ducts can be used as the power distribution trunk line for heavy-duty electromechanical equipment in ordinary multi-story civil buildings.

Flame-retardant Suzhou dense bus duct: The copper busbar is wound with 3 layers of PTFE film, and the power frequency withstand voltage can reach 3750V. After the busbars are wound, imported PayChem or domestic heat-shrinkable sleeves are used as the sheath, and flame-retardant insulating sheets are used to isolate the busbars of each phase. The oxygen index is above 32, reaching the electrical and flame-retardant performance of Suzhou dense busbars.

Fire-resistant Suzhou dense busway: equipped with special fire-resistant performance, high insulation performance and non-combustible special epoxy resin powder is sprayed on the busbar, and the accessories are fire-resistant insulation parts. Specially designed and processed in the busbar connector, plug-in box, busbar casing and other parts, it has the fire resistance performance that meets the fire resistance standard. Low-voltage power distribution trunks such as fire pumps, fire elevators, and emergency generators should use fire-resistant Suzhou dense bus ducts to ensure the supply of power in the event of a fire to facilitate fire fighting.
