Description

Product characteristics and application　　

Mining PVC insulated power cables are used for fixed laying under mining well or up ground at A.C 50Hz, and the power transmission on power transmission and distribution line at rated voltage UO/U up to and include 0.6/1kV. It can also be allowed to be used in D.C systems with the nominal system voltage not be 1.5 times more than the rated voltage of cable.
The MVV cables are suitable for being laid under wells, tubes and ducts. Cables cannot bear the effect of outside force.
The MVV22 cables are suitable for being laid under wells, tubs, ducts and soil, the cable could bear mechanical outside force but could not bear larger pulling force.
