Abstract
The utility model discloses an offshore low-smoke zero-halogen slurry-resistant power cable in cable field. The power cable comprises a triphase wire harness arranged in the center of the power cable; the triphase wire harness is formed by twisting three phase lines into a bunch; each phase line comprises a core wire conductor and an insulating layer at the external of the core wire conductor; a halogen-free winding package belt is wound and packed at the external of the triphase wire harness; a crosslinking polyolefin inner sheath is arranged at the circumference of the halogen-free winding package belt; a polyester belt is arranged at the external of the crosslinking polyolefin inner sheath; a tin plated copper braid layer is arranged at the external of the polyester belt; and a fatlute resistant polyolefin external sheath is arranged at the external of the tin plated copper braid layer. The power cable has the advantages of high strength, corrosion resistance, and good shielding property, and can be used as a power cable in development and utilization in offshore energy field; and the power cable can meet the design requirements of Norway NEK: 2004 standard.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of power cable.
Background technology
Along with development of technology, the development and use of marine energy sources become one of important channel of energy sources gradually, in the oil exploitation in coastal waters, need a large amount of electrification cables, as the power cable that use at the sea, need its have than general cable better insulate, fire resistance, simultaneously, also need it to have the salt tolerant corrosion, the erosion of oil resistant and mud is difficult for aging characteristics; In addition, also need it to have higher-strength, the energy tension; Common cable of the prior art can not satisfy this high request.
The utility model content
The purpose of this utility model provides a kind of coastal waters with the low smoke and zero halogen power cable of anti-mud, make its have high strength, corrosion-resistant, shield.
The purpose of this utility model is achieved in that the coastal waters low smoke and zero halogen power cable of anti-mud, comprise the three-phase wire harness that the center is provided with, the three-phase wire harness is by three stranded bunchys of phase line, each root phase line comprises cored wire conductor and the outer insulating barrier of cored wire conductor, outside the three-phase wire harness, be surrounded with the Halogen twining package tape, Halogen twining package tape periphery is provided with the cross-linked polyolefin inner sheath, the cross-linked polyolefin inner sheath is provided with polyester belt outward, polyester belt is provided with tincopper fuse wire braided armor outward, and tincopper fuse wire braided armor is provided with the polyolefin oversheath of oil resistant mud outward.
In this cable, adopt cross-linked polyolefin inner sheath and polyolefin oversheath, double shielding can be provided, be provided with polyester belt between the two, when the cable bending, between cross-linked polyolefin inner sheath and the polyolefin oversheath slide relative can be arranged, avoid producing bigger internal stress; Simultaneously, both all have good physical and chemical performance, make that cable not only has elasticity, it has the effect of oil resistant, salt tolerant, anti-mud simultaneously, and cable is aging slow, long service life; Tincopper fuse wire braided armor has the effect that strengthens the cable resistance to tension, also makes it can bear certain mechanical pressure, simultaneously, also has good shielding action; This cable has high strength, corrosion-resistant, shielding advantage well, can be used in the development and use of coastal waters energy field, uses as power cable; It can meet the designing requirement of Norway NEK:2004 standard.
For further strengthening the fire resistance of cable, be provided with fire-resistant isinglass belt between described cored wire conductor and the insulating barrier.Fire-resistant isinglass belt has good fire resistance properties, can improve the fire resistance rating of cable.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 polyolefin oversheath, 2 tincopper fuse wire braided armors, 3 polyester belts, 4 cross-linked polyolefin inner sheaths, 5 Halogen twining package tapes, 6 insulating barriers, 7 fire-resistant isinglass belts, 8 cored wire conductors.
Embodiment
As figure, be the coastal waters low smoke and zero halogen power cable of anti-mud, comprise the three-phase wire harness that the center is provided with, the three-phase wire harness is by three stranded bunchys of phase line, each root phase line comprises cored wire conductor 8 and the outer insulating barrier 6 of cored wire conductor, for strengthening fire resistance, can between cored wire conductor 8 and insulating barrier 6, fire-resistant isinglass belt 7 be set; Cored wire conductor 8 is made of the multiply tinned copper wire, has the ability of anti-repeatedly bending, and insulating barrier 6 can be made by cross-linked ethylene/second third insulating material; Outside the three-phase wire harness, be surrounded with Halogen twining package tape 5, Halogen twining package tape 5 peripheries are provided with cross-linked polyolefin inner sheath 4, the cross-linked polyolefin inner sheath 4 outer polyester belts 3 that are provided with, the polyester belt 3 outer tincopper fuse wire braided armors 2 that are provided with, the tincopper fuse wire braided armor 2 outer polyolefin oversheaths 1 that are provided with oil resistant mud.
