High -efficient compact cable

The utility model discloses a high -efficient compact cable, including conductor, conductor screen, insulating layer, insulation screen and polyethylene outer jacket, the inboard of polyethylene outer jacket is provided with composite aluminium -plastic tape, the composite aluminium -plastic tape inboard is provided with the semiconduction area that blocks water, the semiconduction blocks water in -band side and is provided with the copper wire shielding. The utility model discloses reduce the thermal resistance of cable, guaranteed the bending property of cable, reduced cable body weight to no longer receive the restriction of single -deck factory length and transportation, thereby need not only not reduce engineering cost increasing cable joint in the engineering application, prevented the potential safety hazard moreover, have the simple structure compactness, the current -carrying gauge height, transform with low costs, beneficial effect such as reliability height.
