YLMX / N fire-resistant and corrosion-resistant flame-retardant bus duct
YLMX / N fire-resistant, corrosion-resistant and flame-retardant busway is a new product developed after summing up many years of busbar production experience and is an indispensable transmission and distribution equipment for fire protection systems.
This product is designed according to the requirements of JB / T10327-2002. It adopts an inner and outer two-layer shell structure. There is a heat-resistant and heat-resistant fireproof board and fireproof cotton between the shells. After heat insulation treatment, when a fire occurs, The temperature rise of the busbar inside the busway is low. In addition, the surface of the busway shell is provided with fire-resistant paint. When there is a fire source, the fire-resistant paint coated on the shell foams, closes all openings, prevents water from entering, prevents short circuit of the line, and ensures normal transmission of electrical energy.
The material of the busbar connector, the connector and the support is 9 5 porcelain, which has high temperature resistance and good insulation performance. Since 95 5 porcelain has high temperature resistance and insulation performance, the high temperature resistance can reach 1700 ° C, which is sufficient to ensure the In a fire environment, it can effectively ensure the normal and effective supply of electricity when the busway is exposed to fire.
In addition to the good electrical and service performance of general bus ducts, the bus ducts also have the characteristics of small size and strong corrosion resistance. The busway can withstand 3 hours of fire when the fire resistance temperature is 700 ~ 850 degrees, and 1.5 hours at 950 ~ 1050 degrees. It is suitable for the power transmission mains of fire fighting equipment. When a fire fire breaks out, such transmission mains will not cause fire It is short-circuited, so it has strong fire resistance. It is an ideal product for power transmission mains of fire protection equipment.
