BSM10 series casting fireproof busway is the new product developed by our company on the basis of BSM7 casting fireproof busway and has completely independent intellectual property. BSM10 series casting fireproof busway does not need the help of fireproof thermal insulating layer to achieve the fire performance any more. The product does not burn with the presence of fire. The integrity of the product will not be damaged within 60 minutes under the standard experiment condition of BG/T537-2005. The existing casting fireproof busway of the industry achieves the fire resistance by adding thermal insulation refractory layer outside the casting busway. But the presence of thermal insulation refractory layer decreases heat dispersion of the product greatly. The conductors need to increase by two times on the basis of original casting bus. As a result, the cost of conduct is increased significantly. This not only wastes resources but also increases the user’s cost. The emergence of BSM10 resolves the difficult problem. The product is not only resistant to water, acid corrosion, alkali corrosion, explosion but also reaches the fire performance. As the fire sprinkler will start automatically under the fire condition, the highest protection level of intensive insulated fireproof bus is IP65. The product conductivity may be damaged due to that the water collected exceeds the product limit. The protection level of BSM10 casting fireproof busway teaches the highest level IP68. It is a type of fireproof busway product satisfying fire control in real meaning. Its emergence plays a role in guiding the development of the Industry.
