Cable protection measures

      With the rapid development of power cables laid underground engineering requirements for higher cable protection proposed cable protection sleeve is the use of polyethylene PE pipe through sand blasting and high quality pre-treatment, or dip coating, heat curing produced by technology. It is to protect an electrical wire and cable insulation tubes most commonly used. Because it has good insulation properties, high chemical stability, no rust, no aging, can be adapted to harsh environments and is widely be applied.
     Use cable protection sleeve protects the cable can achieve the following advantages:
     1, good corrosion resistance, long life, with the use of saline land in the wet.
     2, flame retardant, heat resistance, long-term use without deformation at 130 degree heat, fire does not burn.
     3, high strength, high rigidity. Buried under the carriageway with no need to add a protective layer of concrete, can roll faster cable construction progress.
     4, cable protection sleeve, whether pipe or pipe fittings have a certain flexibility, can withstand the weight of external and infrastructure damage caused by subsidence.
     5, has good resistance to external signal interference.
     6, smooth wall, do not scratch the cables. Design uses a socket type connection, easy installation and connection. Plus rubber ring seal joints adapt both thermal expansion and contraction, but also to prevent sediment from entering.
