Our company produces flame-resistant FRP cable pipe box adopts the flame retardant polyester, high density glass fiber as well as high strength new material. It is excellent in quality and reasonable in price, and is the updated product of iron tube trays. FRP cable pipe trays has high strength and is anti-corrosive, anti-aging, and flame-resistant and can be stretched and curved. The insulating ability is high and it is environment serviceable that won't be affected below zero *0℃ to *0℃, non-toxic, tasteless, and it is of light weight, long lifespan and easy installation. Each technical specification conforms to JT/TEMOI****8 "highway with polyester glass fiber reinforced plastic cable duct box", which issued by Ministry of Communications traffic engineering overseeing examination center. It meets glass fiber reinforced plastic cable duct box's specification of the Ministry of Railways product quality surveillance test center, and FRP cable pipe box is widely applied to railroad and highway, municipal administration construction, electric power communication bridge and tunnel. The equipment won consistent high praise from the Ministry of Railways, the Ministry of Communications Department and users.
