Abstract
The utility model discloses an environment-friendly type watertight-type fireproof four-core marine cable, which is characterized in that a conductor is formed by twisting a plurality of tinned annealed copper wires, wherein a silicon rubber insulating layer is extruded on the conductor and combined with a double-layer lapping mica tape to form an insulating wire core, the four insulating wire cores are twisted together with water-blocking type filling ropes into a cable to form a cable core, and a water-blocking wrapping tape layer formed by lapping, an extruded thermoplastic TPV (thermoplastic vulcanizate) elastomer inner sheath layer, a weaved metal wire armour layer, and an extruded thermoplastic TPV elastomer outer sheath layer are sequentially arranged on the outer layer of the cable core; and hydrophobic ointments are filled in a gap between the conductor and the silicon rubber insulating layer, a gap between the silicon rubber insulating layer and the double-layer lapping mica tape, and a gap between the respective adjacent layers of the double-layer lapping mica tape, the water-blocking wrapping tape layer, the inner sheath layer, the weaved metal wire armour layer and the outer sheath layer respectively. The environment-friendly type watertight-type fireproof four-core marine cable disclosed by the utility model can meet requirements on the longitudinal waterproof performance, the moisture-resistant performance, the fire-resistant performance and the environment-friendly performance of marine cables.
Description
Technical field
The utility model relates to a kind of power cable, relates in particular to a kind of environment-friendly type naval vessel watertight type fireproof cable, belongs to technical field of electric wires and cables.
Background technology
Cable is directly connected to fail safe, reliability, advance and the fight capability of boats and ships as nerve and the blood vessel on naval vessel.Modern ships accumulative total is laid all size cable and is reached more than tens of kilometers, spreads all over full ship.The naval vessel is Modern Ships with the longitudinally water blocking cable, especially one of important auxiliary products of submarine.The longitudinally water blocking characteristic of cable can guarantee when boats and ships generation Local Accidents brings disaster to cable, stop seawater from construction of cable internal leak to other cabins or and then enter instrument and equipment, guarantee that watertight bulkhead reaches safely whole ship unsinkability.Work as simultaneously the cable local damage, only need local the reparation, can not cause whole cable to scrap even involve the electric equipment of precision owing to the intrusion corrosion of seawater.Stipulated naval vessels Cable choosing rule among the ministerial level standard C BPZ 221-1998 that China Shipbuilding Industry Corporation promulgates " naval vessels Cable choosing rule ".This standard requires with selection clear to be arranged to the watertight type cable: for the fixing cable by pressure hull, bulkhead in cabling and the ship of submarine outboard, below the surface ship damage line and the cable that passes watertight bulkhead all should adopt and meet the longitudinal sealing cable that water pressure resistance requires.Cable in the prior art is difficult to meet the demands.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, provides a kind of environment-friendly type naval vessel with the watertight type quad of preventing fires, in the hope of satisfying the requirement of cable for ship on vertical waterproof, humidity, fire-resistant and environmental-protecting performance.
The utility model technical solution problem adopts following technical scheme:
The utility model environment-friendly type naval vessel with the design feature of watertight type fire prevention quad is: conductor adopts many stranded the forming of tin annealed copper wire, extrude silicone rubber insulation layer and double-deck wrapped mica tape formation insulated wire cores at described conductor, thoroughly do away with the edge cores and the common twisted synthesizing cable of waterproofing type gasket for packing consists of cable core by four, the skin of described cable core set gradually wrapped formation the belting layer that blocks water, extrude thermoplasticity TPV elastomer inner restrictive coating, knit wire armour and extrude thermoplasticity TPV elastomer external sheath layer; Between described conductor and the silicone rubber insulation layer, between silicone rubber insulation layer and the double-deck wrapped mica tape, and be filled with respectively the hydrophobic oil paste in the slit between each adjacent layer of the wrapped mica belt of described bilayer, the belting layer that blocks water, inner restrictive coating, knit wire armour and external sheath layer.
The utility model environment-friendly type naval vessel also is with the design feature of watertight type fire prevention quad: described silicone rubber insulation layer, inner restrictive coating and external sheath layer be the environment-friendly type raw material that meets the RoSH instruction be material.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, insulating barrier has adopted the silastic material of excellent electrical properties, Good Heat-resistance in the utility model, and material is easy to get, and its normal phase working temperature reaches 180 ℃, improves ampacity and the resistance to elevated temperatures of cable.In the situation of fire, the silicon dioxide that generates after the silicon rubber burning also is insulator, has improved the fireproofing of cable performance;
2, in the utility model between the structure sheaf slit fill with the hydrophobic oil paste, played the effect of good vertical waterproof.
3, the utility model external sheath layer adopts TPV elastomer material, the advantage such as have the intensity height, percentage elongation is large, and oil resistance is excellent, easy to process, it has excellent resistance to elevated temperatures simultaneously, the long-term work temperature can reach 105 ℃, and heat aging performance is excellent, and the life-span is long.
4, silicone rubber insulation layer, inner restrictive coating and external sheath layer are take the environment-friendly type raw material that meets the RoSH instruction as material in the utility model, and its environmental-protecting performance is excellent.
