Abstract

The utility model relates to a novel armored submarine cable comprising three cables with the same structure, wherein each cable uses a copper wire conductor as a core; the outer surface of the copper wire conductor is sequentially coated with a conductor shielding layer, an insulating layer, an insulating shielding layer, a semiconductor cotton tape layer, a copper wire shielding layer, a copper strip covering layer, a water-blocking tape layer and a medium-density polyethylene protective layer; the outer surface of the three cables as the core is sequentially coated with a water-blocking tape layer, a medium-density polyethylene protective layer, an armored layer, a polyester tape layer and a medium-density polyethylene protective layer; and packing is arranged between the cable and the water-blocking tape layer coated on the outer surface of the cable. The novel armored submarine cable is characterized in that the armored layer is formed by twisting carbon fibers with circular cross sections. The carbon fiber is used for replacing the copper wire to be twisted to the armored layer, the production cost of the cable can be reduced, the weight of the cable is lighted, the external diameter of the cross section is reduced, and the capability of bearing the mechanical pressure of the cable is increased; in addition, the utility model has strong corrosion resistance and good fatigue resistance.

Description

Novel armoured ocean cable

Technical field

The utility model belongs to seabed transmission facility technical field, particularly relates to a kind of novel armoured ocean cable.

Background technology

At present, information conduction and electric power that submarine cable is mainly used between island or the Offshore Units are carried, be divided into seabed communication cable and sea electric power cable, along with the fast development with the marine energy production technique of improving constantly of global networking degree, the demand of submarine cable is also increasing.In the prior art; sea electric power cable all includes the wire armoring layer; be the circular stranded protective layer that forms of steel wire promptly by the cross section; this wire armoring layer can effectively increase the mechanical property of cable; thereby make cable can satisfy the instructions for use of environments such as subsea; but because the restriction of steel wire on physical property, it is big and bear the shortcoming of the ability of mechanical pressure to make this wire armoring sea electric power cable have weight, and the production cost height of cable, the cross section external diameter is big and transportation is inconvenient.

Summary of the invention

The utility model provides the carbon fiber armoured ocean cable that a kind of production cost is low, the cross section external diameter is little, conveniently transport for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of novel armoured ocean cable; comprise the cable that three root architectures are identical; described every cable all is core with the copper conductors; outer surface in copper conductors is coated with conductor shield successively; insulating barrier; insulation screen; semiconductor cloth belt; the copper wire screen; the copper strips lapping layer; water blocking tape layer and medium density polyethylene protective layer; with three cables is that core is coated with water blocking tape layer successively at its outer surface; the medium density polyethylene protective layer; armour; polyester belt and medium density polyethylene protective layer; cable and be coated between the water blocking tape layer on the cable outer surface and be provided with filler, it is characterized in that: described armour is circular stranded the forming of carbon fiber wire by the cross section.

Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be that the circular stranded armour that forms of carbon fiber wire replaces in the known technology by the cross section promptly be the circular stranded armour that forms of steel wire with the cross section, because comparing with steel alloy, carbon fibre material has advantages such as in light weight, that tensile strength is high, corrosion resistance is strong and fatigue durability is good, so have that the production cost of power cable of carbon fiber stranded layer is low, in light weight, a cross section external diameter and to bear the ability of mechanical pressure strong.
