MPP power cable sheathing is made of special materials of a new type of pipe,Website:://.chinaextruders.net, it meets the requirements of modern urban development, for buried in the 2-18M range of applications under conditions of trenchless pipe laying technique. The tube has not pollute the environment, does not affect the traffic, the formation of structural damage is small, safe and reliable construction, short cycle, without transport and stacking miscellaneous soil, low cost, and high social and economic benefits. I plant development and production of MPP power cable sheathing is the only one using trenchless technology for pipeline construction, both to ensure the reliability of the network, reducing the failure rate of the network, but also to make content available in the market environment has been greatly improved .Features: High tensile and flexural strength, rigidity, good toughness, high temperature resistant, corrosion resistance, light weight, easy construction, easy connection.Performance: Tensile strength ≥24 Mpa, flexural strength ≥27 Mpa, flexural modulus ≥930 Mpa Vicat heat (1Kg, 500C / h) 0C ≥126, coefficient of friction <0.35 ≤1% recovery longitudinal roundness <3.5 % test flat (flattening to 1/2).
