Abstract
The utility model relates to a metal composite strip radial water-resisting submarine cable which comprises a coating layer, a steel wire armor layer in the coating layer and an inner padding layer, wherein an optical cable unit and a plurality of conductor units are arranged in the inner padding layer; filling strips are arranged in gaps among the optical cable unit and the conductor units and the steel wire armor layer, conductor shielding layers are arranged outside conductors in the conductor units; insulating layers, insulating and shielding layers and water-resisting strips are sequentially arranged outside the shielding layers; copper-plastic or aluminum-plastic composite strips are coated on the water-resisting strips; and high density polyethylene sheathes are arranged outside the copper-plastic or aluminum-plastic composite strips. The copper-plastic or aluminum-plastic composite strips and the high density polyethylene sheathes are synchronously extruded. The production process of water-proof layers of the metal composite strip radial water-resisting submarine cable only needs to connect one set of composite strip longitudinal wrapping and welding equipment with an ordinary plastic extrusion device in series for completion, thereby realizing simple production process and small equipment investment; and the overall thickness of the water-proof layer of the cable is greatly reduced, the unit weight of the cable is reduced by about 35% and the outer diameter of the cable is obviously reduced, thereby facilitating laying; and the comprehensive cost of the cable is reduced by about 30% and the economic benefits are obvious.
Description
Technical field
The utility model relates to a kind of submarine cable, is specifically related to a kind of employing copper and moulds the mode of (or plastic-aluminum) composite belt longitudinal bag and high density polyethylene (HDPE) sheath and reach radially the metal compound belt of the block-water effect submarine cable that radially blocks water.
Background technology
At present submarine cable is general adopts crosslinked polyetylene insulatedly, and electric pressure is generally 1 ~ 35kV, but crosslinked polyetylene insulatedly is easy to form the water tree in a humid environment under the effect of high-voltage field, causes puncturing, and influences the useful life and the power supply safety of cable.Traditional submarine cable adopts the outer mode of extruding the seamless lead pipe of one deck continuously of insulation to reach the purpose that radially blocks water, and adopt lead extrusion technology can effectively reach the requirement that cable radially blocks water, but there is significant disadvantages in it:
The one, factory must have large-scale plumbous extrusion equipment, have heavy metal pollution in its production process, and equipment investment is big; The 2nd, because plumbous proportion is very high, so final products weight is very heavy, gives to lay and makes troubles; The 3rd, because cable heavily soaks at seawater for a long time, plumbous corrosion meeting has a negative impact to environment.
Summary of the invention
It is good that the technical problems to be solved in the utility model provides a kind of block-water effect, and product weight is light, the metal compound belt that can the not produce lead contamination submarine cable that radially blocks water.
The purpose of this utility model is achieved in that a kind of metal compound belt submarine cable that radially blocks water, comprise serving, in the serving is wire armoring layer and inner cushion layer, be provided with optical cable unit and Duo Gen conductor element in the inner cushion layer, be provided with packing in the gap between optical cable unit and conductor element and the wire armoring layer, conductor in the conductor element is outward a conductor shield, screen is provided with insulating barrier, insulation screen and waterstop outward successively, waterstop is coated with that copper is moulded or aluminium-plastic tape, and copper is moulded or aluminium-plastic tape is the high density polyethylene (HDPE) sheath outward.Copper is moulded or aluminium-plastic tape and high density polyethylene (HDPE) sheath are extruded synchronously.
The metal compound belt that the utility model the provides submarine cable that radially blocks water adopts copper to mould or the mode of aluminum plastic composite belt longitudinal bag+high density polyethylene (HDPE) sheath reaches the effect that radially blocks water.Copper is moulded or aluminium-plastic tape is that copper or aluminium and one deck play the compound and compound material of layer of the macromolecular material of adhesive effect.Utilize the high compactness of metal to play radially good waterproof effect; the high density polyethylene (HDPE) sheath that utilization is extruded is synchronously moulded by copper or aluminium-plastic tape is protected; the high temperature that when extruding the high density polyethylene (HDPE) sheath synchronously, produces can make copper mould or the fusing of the adhesive layer of aluminium-plastic tape and with high density polyethylene (HDPE) sheath close adhesion, finally reach the effect that good longitudinal sealing blocks water.
The utility model radially blocks water, and copper that the radially watertight composition of submarine cable adopts is moulded or plastic-aluminum combined tape thickness is generally 0.25mm, copper or aluminium thickness are 0.15mm, the high molecular bonding layer thickness is 0.10mm, therefore adopt the weight of the cable of this waterproof construction to be generally about 67% of the plumbous cover of same specification waterproof construction cable weight, the price of cable also can reduce about 30%.
Compare with the traditional structure submarine cable, this novel submarine cable that radially blocks water has following advantage:
The production process of 1 watertight composition only needs a cover composite belt longitudinal bag welding equipment to connect and can finish with the common plastics extrusion equipment, and production technology is simple, and equipment investment is little;
The watertight composition general thickness of 2 cables reduces significantly, and it is about about 35% that the cable substance descends, and the external diameter of cable obviously reduces, and is convenient to lay;
3 compare with lead, and environment damage is obviously reduced;
It is about 30% that 4 cable comprehensive costs reduce, and economic benefit is obvious.
