CDCX/N fire retardant rot bus duct is summarized the bus duct production experience for many years, to develop new products, fire protection system is essential for transmission and distribution equipment, the product is designed according to JB/T10327-2002, it adopts two layers inside and outside shell structure, between shell with high temperature resistance, good heat insulation, fire prevention board, fire cotton, after heat treatment, make a fire, bus duct internal bus temperature is low. Busway shell surface additionally equipped with fire retardant coatings, when in case of fire, foam fire retardant coating applied to the shell, all his closed, the water could not enter, prevent the short circuit of circuit, ensure the normal transmission power.
Bus duct connector and plug of support materials for high temperature resistance, good insulation performance, 95 porcelain, because the 95 porcelain has high temperature resistant performance and insulation performance, high temperature resistant up to 1700 ℃, enough to ensure bus duct in fire environment, can effectively guarantee the bus duct under fire, effective normal power supply.
The bus duct besides general bus duct of good electrical properties and operational performance, also has the characteristics of small volume, strong corrosion resistance. The bus duct refractory temperature of 700 ~ 850 degrees can fire under 3 hours, 950 ~ 1050 degrees can withstand the 1.5 hours, adapted to the electricity transmission lines of fire equipment, fire in fire fire, the conveying lines won't short circuit caused by the fire, so they have strong ability of fireproof, fire fighting equipment is electricity transmission lines is the ideal product.
