Lanzhou Mande Xi busbar manufacturing hotline, Gansu fire Busway proposed laying constituted by a fireproof paint coating, the coated foam expanded rapidly in case of fire, the formation of 50mm thick barrier to prevent heat spread inward, Lanzhou fire Busway make in the initial fire 840 ℃ high temperature can continue to supply up to half an hour, to protect senior or super high-rise buildings, shopping malls fire safety smooth power supply system, you can use the elevator emergency evacuation, Gansu fire Busway fire pump is started In order to eliminate disasters, to protect people's lives and reduce property loss for a time. At the same time, pull the structure due to the use of stick after the disaster also had only replacement in fire Lanzhou fire Busway, instead replaced. Gansu fire Busway wound from a homogeneous bond mica-based material made of conductive copper insulating tape, mica insulation pads, adapter, shield, insulated bolts, Lanzhou fire Busway metal shell and cover consisting of , characterized in busbar protective metal casing, the outer wall surface is a layer of foam in a fire rapidly expands to form a uniform coating of the barrier layer. Gansu fire busbar has a complete series, commodity production, small size, large capacity, design and construction cycle is short, easy assembly and disassembly, not burn, safe and reliable, long service life. Lanzhou fire busbar product is suitable for AC 50Hz, rated voltage 380V, rated current of 250A-4000A three-phase four-wire, three-phase five-wire power supply system project. Gansu fire busbar is to provide fire-fighting equipment to the power usage, they are generally not as another use. Lanzhou fire busbar is its heat resistance, heat insulation are relatively good, but not long-term use at full capacity, mainly because of its heat resistance is not very good. Gansu fire busbar refractory period of 60 minutes, 90 minutes, 120 minutes, 180 minutes species, when the temperature reaches 920 ~ 1050 ℃ high temperature will burn, full load operation up to 8 hours. Lanzhou fire busbar by a shell coated with fire retardant paint, bus and stand by the fire-resistant insulation material wrapped refractory mica components. The holder with a plurality of grooves, recesses built into the bus and fixed. At one end there Gansu fire busbar busbar connection box, there are buses in the busbar tap box. Lanzhou fire busbar with excellent insulation properties, can be used continuously in a normal environment, but also in the fire environment continuously for more than one hour, suitable for high-rise buildings and vital facilities in place fire-resistant cable from the transmission and distribution role.
