It is that European & American Market requirement must (more stringent property be tested: UL44PRI oil resistant tries by UL/CSA market access mechanism
Test, CT fire retardancy test etc.), it is therefore desirable to develop a kind of wind-power electricity generation 2000V with UL/CSA double authentication and following fire-retardant
Cold-resistant fixing lays single-core power cables.
Utility model content
In the purpose of this utility model is to provide a kind of wisdom energy wind-power tower, cold-resistant the fixing of high fire-retardance lays single electricity
Power cable.
Realizing the technical scheme of this utility model purpose, to be that high fire-retardance is cold-resistant in wisdom energy wind-power tower fixing lay list
Core power cable, is followed successively by core, the first flexible high-resistance combustion twining package tape, copper strips, the second flexible high-resistance combustion twining package tape from the inside to the outside
With PVC oversheath；Described core includes a conductor and crosslinked polyetylene insulated；Described conductor is twisted again by seven strands of one-level conductors
One, per share one-level conductor is by seven wire strandings, and each wire is stranded by multifilament.
A diameter of 0.511mm of described every monofilament.
A diameter of 2.85mm of the wire after described monofilament left-hand is stranded.
A diameter of 8.1mm of the one-level conductor after described seven wire dextrad are stranded.
A diameter of 23.2mm of the conductor after described seven strands of one-level conductor left-hands are stranded.
Described crosslinked polyetylene insulated thinnest point thickness is 2.74mm；The thickness of the first flexible high-resistance combustion twining package tape is
0.08mm, lapping direction is left-hand；The thickness of described copper strips is 0.12mm, and lapping direction is dextrad；Described second flexible high-resistance
