In order to solve the problems, a large number of bus ducts which are called to have a fire-resistant effect appear in the market at present, but the fire-resistant performance of the bus ducts cannot meet the requirements, and serious potential safety hazards are brought to power transmission main lines on projects. The fire-resistant structure of the bus duct can achieve the aim of passing part of fire resistance test requirements as long as the bus duct is completely sealed by using the characteristics of a pouring material, and then a high-temperature resistant fire-resistant cotton and steel shell with the height of 10-20 cm is wrapped outside the bus duct by pouring. But adopts epoxy resin to directly cast and seal a multi-phase conductor, and then the periphery of the solidified solution is wrapped by a thick fire-resistant plate to achieve the fire-resistant casting type fire-resistant bus duct. Although the waterproof performance is good and the volume is small, the melting point of the epoxy resin material is only 145-155 ℃, even if the outer layer fireproof plate is thick, the outer layer fireproof plate cannot completely insulate heat, the physical properties (including waterproof performance, heat dissipation capacity, insulating capacity and the like) of the epoxy resin material can be lost within 90min at the high temperature of 950 ℃, the physical properties (including heat conductivity coefficient, expansion coefficient, ductility and the like) of a pouring melt and a conductor are far away, the risk of explosion and cracking easily occurs during long-time operation, and the pouring structure of the epoxy resin material is very difficult to overhaul and cannot meet the fire protection requirement. Therefore, a fire-resistant bus duct with excellent performance is designed to solve the problems.
