FRP cable protection tube, a new type of composite tube, the resin matrix and glass fiber composite materials made to enhance the bonding with the unsaturated resin molding and modern cable construction projects supporting high-quality cable protection catheter products. Compression and strong, light weight, smooth wall, the friction coefficient is small and easily in the wear of the cable, does not damage the cable. The move, transport than metal pipe and cement pipe easy and convenient. Construction and installation is simple, to save trouble and effort. Corrosion resistance, insulation, non-magnetic, acid, alkali, flame retardant, antistatic. Looked good elastic modulus, and completely resolved metal pipe perishable, non-twist elastic characteristics, but also to overcome the plastic tube and easy to aging, poor impact strength deficiencies. Water resistance in wet or water long-term use is not degenerate. Because of the specific properties of glass fiber reinforced plastic, the glass pipe the useful life of more than 50 years. Facilitate the construction and efficiency, especially in the repair of a specific project, is the most ideal protection devices in the power cable engineering, communications cable, municipal engineering and road laying underground cables, the cable across the river bridge using the most appropriate light. Urban power grid construction and renovation project. (2) Urban Services Improvement Project. (3) civil aviation airport construction projects. (4) industrial parks, residential projects. (5) Transportation road and bridge construction.
