Some current submarine cables are not suitable for large span and lay, and its anti-pressure ability, water resistance are poor, are laid on for a long time seabed, easily be subject to seawater corrosion, after corrosion, can cause a large amount of infiltrations, cause cable failure, and easily phase mutual interference between core, not wear-resisting easily aging, useful life is short.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide one to have good waterproof effect, and resistance to compression is anti-aging, and useful life is normal, the sea electric power cable that suitable large span is laid.
The technical solution of the utility model is: a kind of sea electric power cable, comprise several cores, described core is comprised of conductor, semiconductor waterstop, insulating barrier, aluminium cover from inside to outside successively, described insulating barrier is comprised of conductor shield, XLPE insulating barrier, insulation screen, the outer wrapped one deck band of described core, the gap between described core is provided with packed layer, and described band is set with inner sheath outward, described inner sheath outer wall is set with wire armoring, and described wire armoring is set with oversheath outward;
As preferably, described conductor shield, XLPE insulating barrier, insulation screen are one-body molded;
As preferably, described aluminium cover is vertical bag embossing aluminium cover;
As preferably, described band is the twining package tape that blocks water;
As preferably, described inner sheath is high-density polyethylene layer;
As preferably, described packed layer is water blocking yarn or waterproof paste;
As preferably, described wire armoring layer thickness is 4～6mm;
As preferably, the wrapped layer of non-woven fabric of described wire armoring layer outer wall.
The beneficial effects of the utility model are: the utility model water resistance is good, and its vertical diameter, to all there being good waterproof effect, can be tackled suppressing of seabed, is difficult for burn into wear-resisting anti-aging, and long service life is specially adapted to seabed large span and lays.
