Fire resistant busbar
DCB-FR mineral refractory busduct, with excellent fire resistance and waterproof performance, is especially suitable for the emergency power supply circuit of low-voltage power distribution system. When the production and domestic power is cut off in case of fire, it can still reliably guarantee the power.
DCB-FR mineral refractory busduct, as the overall solution of low voltage busduct, well meets the power distribution requirements of commercial and civil buildings.
Dingsheng DCB-FR mineral refractory busduct has the advantages of small volume, compact structure, reliable operation, large transmission current, easy to tap and feed, convenient maintenance, low energy consumption, good dynamic and thermal stability, which has been widely used in all walks of life. At the same time, due to the use of new technology and new process, it greatly reduces the contact resistance and resistance at both ends of the bus duct and at the junction of the branch port Temperature rise, so as to improve the safety and reliability of the busduct, make the whole system more perfect.

2、 Product standard
Product design standard: gb7251.1, gb7251.6
Fire resistance standard: GA / T 537-2005, IEC 60331-21:1999
All resins and fillers are from German, and some important raw materials are also imported from German. Refractory resin and mineral casting molding, as well as the dual protection of the copper shell after fire treatment, cast the mineral refractory bus duct. Bright red is used as the standard color of the product, which is easy to identify in the fire environment and meets the relevant design specifications.
