Unsaturated Resin Fiberglass Cable Protection Tube Is Used In Those Fields

Jun 28, 2020

 FRP cable protection tube is a new type of composite material tube, which is composed of FRP unsaturated resin as the matrix and glass fiber as the reinforcing material, and is bonded with FRP unsaturated resin High-quality cable protection conduit products that are shaped and can be matched with modern cable engineering construction. Strong pressure resistance, light weight, smooth inner wall, small friction coefficient, easy to wear the cable without damaging the cable. It is easier and more convenient to move and transport than metal steel pipes and cement pipes. The construction and installation are simple, saving both labor and effort. Strong corrosion resistance, insulation, non-magnetic, acid, alkali, flame retardant, antistatic. It is expected that the elastic modulus is good, which completely solves the characteristics of metal pipes that are easy to rot and have no twisting elasticity. It also overcomes the deficiencies of plastic pipes that are easy to age and have poor impact resistance. Good water resistance, can be used for a long time in wet or water without deterioration. Due to the specific properties of FRP, the service life of the FRP tube is more than 50 years. The construction is convenient, and the efficiency is particularly prominent when rushing to repair specific projects. It is the most ideal protection device for laying cables in power cable engineering, communication cable municipal engineering, and roads. It is the most suitable and portable to use cables for crossing rivers and bridges.

    Scope of application: FRP cable protection pipes can meet various specific requirements of users, and can be applied to a variety of site areas such as muddy soft soil engineering areas, collapsible loess areas, lakes and Haidian areas, and areas with high depth chemically corrosive media. Adopt the matching special pipe pillow combination, which can form a multi-layer multi-row multi-pipe pipe exhausting method. When the cable crosses the bridge, crosses the river and other special environments, it acts as a protection tube.

Typical application areas:

   (1) Urban power grid construction and renovation projects.

   (2) Urban municipal reconstruction project.

   (3) Construction of civil aviation airport project.

   (4) Construction of industrial parks and communities.

   (5) Construction of traffic roads and bridges.

Product features

  ◎High strength, used for direct burial under the traffic lane, without adding protective layer of suspected soil, can accelerate the construction progress of the project.

  ◎Good toughness, can resist the damage caused by external pressure and foundation settlement.

  ◎Electrical insulation, flame retardant, heat resistance is good, can be used at 130 degrees high temperature for a long time without deformation.

  ◎Corrosion resistance, long service life, can resist the corrosion of various corrosive media such as acid, alkali, salt and organic solvents, and its service life can reach 50 years.

  ◎The inner wall is smooth and does not scratch the cable. The rubber sealing ring socket connector is convenient for installation and connection, and adapts to thermal expansion and contraction.

  ◎Small proportion, light weight, one person can lift, two people can implement installation, can greatly shorten the construction cycle, reduce installation costs, while avoiding the long exposure of road excavation, affecting the urban traffic order and other issues.

  ◎ No electric corrosion, non-magnetic. Unlike magnetic materials such as steel pipes, eddy currents cause cables to heat and damage.

  ◎Wide range of application: FRP cable protection tube is suitable for use as a protection tube when the cable is buried in the ground, and it is also used in high-demand occasions such as cable crossing and river crossing. Adopt the matching professional tube pillow combination, which can form a multi-layer multi-row multi-pipe tube exhaust method.
