Abstract

The utility model discloses a power cable applied to the seabed. The power cable applied to the seabed comprises the main conductors, the subordinate line core conductors and the control line core conductors, and the insulating shielding layers are wrapped on the outsides of the main conductors, the subordinate line core conductors and the control line core conductors respectively. The four control line core conductors are distributed on the outside of one subordinate line core conductor, and a lapping layer, a water-blocking filling rope and a semiconductor water-blocking belt are wrapped on the outsides of the four control line core conductors and the subordinate line core conductor orderly, so that a control line core is formed. Every two of the four control line cores are arranged tangentially, the main conductors are arranged between every two control line cores and among the four control line cores, and a lapping layer, an asbestos filling rope, an inner sheath, a steel wire braided and armored layer, a composite moisture-blocking and water-blocking layer, a steel belt armored layer and an outer sheath are wrapped on the outsides of the four control line cores and the main conductors orderly. The power cable applied to the seabed of the utility model is simple in structure, reasonable and novel in design, long in use time and stable and reliable in performance, can block water and moisture effectively, is corrosion resistant, and is not easy to damage.

Description

A kind of power cable that is applied to seabed

Technical field

The utility model relates to cable technology field, relates in particular to a kind of power cable that is applied to seabed.

Background technology

Sea electric power cable in seabed work, is subject to the impact of sea beat, seawater corrosion due to for a long time for a long time, easily causes power cable to be corroded, and easily fracture, and impact normal operation, also wastes resource, needs to improve.

Utility model content

The utility model object is exactly in order to make up the defect of prior art, and a kind of power cable that is applied to seabed is provided.

The utility model is achieved through the following technical solutions:

A kind of power cable that is applied to seabed, include leading body, subordinate line core conductor and control line core conductor, described leading body, subordinate line core conductor and control line core conductor outside are surrounded by insulation screen, described subordinate line core conductor outside is evenly equipped with four control line core conductors and is surrounded by successively belting layer, gasket for packing and the semiconductor waterstop formation of blocking water controlled core, four are controlled to core tangent placement between two and control between core and between four control cores and be respectively equipped with leading body at every two, outside is coated with lapping layer successively, asbestos gasket for packing, inner sheath, steel wire woven armored layer, compound gear tide watertight layer, steel-tape armouring layer and oversheath.

The utility model has the advantages that: the utility model is simple in structure, novelty reasonable in design, the gear tide that can effectively block water, and corrosion-resistant, not fragile, service time is long, stable and reliable for performance.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.
