FRP Cable Casing Pipe is resin as basic body, continuous glass fiber and its fabric as reinforced material. They are manufactured by winding process which is controlled by computer.
The FRP cable casing pipe is suitable for the laying of the cable be used for electric power and communication at various occasions. Especially the cable which passes the traffic arteries, river, bridge, etc special environment, it can represent the easy construction, high strength, etc advantages adequately. The FRP cable casing pipe is widely used for electric power, communication, traffic, infrastructure establishment of civil aviation airport, etc.
◎ high strength, buried directly under the lane, no need concrete block protection layer, can speed up the construction progress
◎ toughness, resistance to external stress and the damage caused by foundation settlement
◎ electric insulation, fire-retardant, heat resistance, and can be long-term use of 130 degree heat without deformation
◎ corrosion resistance(acid, alkali, salt and organic solvents and other corrosive media), long life, up to 50 years life
◎ smooth wall , do not scratch the cable. Socket rubber ring joints, easy installation and connection, and adapt to expansion and contraction
◎ proportion of small, light weight, one person can carry, two persons can install, can greatly reduce construction period, lower installation costs, and avoid long exposure to road excavation, and other traffic issues
◎No corrosion, non-magnetic
◎ wide range of applications: FRP cable protection pipe for laying cables underground for protection, and also high demand applications while going through the bridge and crossing the river .Tube pillow by supporting the professional portfolio can be composed of multi-row multi-column multi-conduit pipe way.
