NHMC series mineral fire-resistant Bus duct is a new generation of functional Bus duct developed based on XLR full resin casting Bus duct. The bus first uses high-performance mineral fire-resistant insulation materials, and then castes fire-resistant insulation resin upgraded to IP68. The outer layer is covered with Class A incombustible materials, and the whole is covered with a layer of steel shell coated with fire-resistant coating. While improving the structural strength of the product, it can also withstand a 180 minute combustion test at a temperature of up to 1100 ° C, It has four functions: waterproof, fireproof, anti-corrosion, and explosion-proof lights<
Widely used in power transmission and distribution systems in the shipbuilding, chemical, metallurgical, and coal mine lighting industries, as well as in high demand firefighting locations, to ensure continued power supply in case of fire.
The Bus duct conductor bus bar is wrapped with ceramic fire resistant composite tape, which is a kind of organic polymer material - ceramic fire resistant silicone rubber and high temperature resistant glass fiber cloth as the base material, which is rolled and compounded, and starts to harden to form a ceramic shell at a temperature above 350P ℃. In the event of a fire, the "ceramic" hard shell can play a good role in flame retardancy, fire resistance, fire prevention, and fire isolation, with a maximum temperature of up to 3000 ℃.
The outer layer of the ceramic fire resistant and fire-resistant composite tape wrapped around the busbar and the inner layer of the non combustible material are integrally filled with fire-resistant resin insulation material, which has both insulation and fire-resistant properties. When the combustion temperature reaches 600 ° C, it forms a layer of insulation with foam expansion The layer prevents the invasion of flames and heat.Monday to Sunday 6:00 - 23:00
