FRP/GRP cable protection conduit
The fiberglass cable protection tube is made by winding with a microcomputer controlled machine. It is made of resin as the matrix, alkali free glass fiber and fabric as reinforcement materials, and is made of fiberglass through winding process., It has high strength, high voltage resistance, light weight, easy installation, safety and reliability, strong insulation performance, can withstand corrosion from various corrosive substances, strong resistance to parallel water leakage, and a long service life of up to 50 years. Highly favored by engineering professionals in the industry.
Advantages of fiberglass cable protection tube
① It has good electrical insulation, flame retardancy, heat resistance, no electrical corrosion, no magnetism, and can be used for a long time at 130 ℃ without deformation.
② Corrosion resistance, long service life, able to resist corrosion from various corrosive media such as acid, alkali, salt, organic solvents, etc. Its service life can reach 50 years.
③ The inner wall is smooth and does not scratch the cable. The flat end interface or rubber sealing ring socket joint is easy to install and connect, and can adapt to thermal expansion and contraction.
④ Small specific gravity, light weight, easy installation, can greatly shorten the construction period and reduce installation costs.
⑤ It has a wide range of applications and can be used in situations with high requirements such as cable crossing and river crossing. With the use of matching professional pipe pillows, it can form a pipeline layout with multiple layers, columns, and conduits.
Application of fiberglass cable protection tube
Fiberglass cable conduit is suitable for laying power and communication cables in various occasions, especially for cables crossing special environments such as traffic arteries, rivers, bridges, etc. It can fully reflect its advantages of easy construction and high strength. Fiberglass cable conduit is widely used in infrastructure construction such as power, communication, transportation, civil aviation airports, etc.
