BSM10 series cast-type fire-resistant bus duct is a new product independently developed on the basis of our company's BSM7 cast-type fire-resistant bus duct with completely independent intellectual property rights. BSM10 series cast-type fire-resistant bus duct no longer relies on fire-resistant insulation layer to achieve fire resistance. The product does not burn under flame state. According to the standard experimental conditions of BG/T537-2005, the integrity of the product is not destroyed in 60 minutes. The existing cast-type fire-resistant bus duct in the industry achieves fire resistance by adding a heat-insulating fire-resistant layer to the cast bus duct, but the addition of the heat-insulating fire-resistant layer greatly reduces the heat dissipation performance of the product. The conductor needs to be increased by more than two times on the basis of the original cast bus duct, which greatly increases the cost, wastes resources and increases the cost of users. The advent of BSM10 solves this problem. The product is not only waterproof, acid-resistant, alkali-resistant, and explosion-proof, but also achieves fire resistance. Because the fire sprinkler will automatically start under fire state, the highest protection level of densely insulated fire-resistant bus duct is IP65, which may damage the conductive function of the product due to water collection exceeding the performance limit of the product. BSM10 cast-in-place fire-resistant bus duct has the highest protection level of IP68 and is a bus duct product that truly meets the requirements of fire resistance. Its launch has played a leading role in the development of the industry.
