Abstract

The invention relates to a cable, in particular to a mud-resistant power cable, which comprises a cable core and a sheath arranged outside the cable core, wherein the cable core is formed by stranding insulating wire cores, and a high flame retardant filler is filled in a gap of the cable core; a wrapping tape is wrapped outside the cable core, and an inner sheath is extruded outside the wrapping tape; a shielding layer is braided outside the inner sheath, and an outer sheath is extruded outside the shielding layer; the insulating wire core is formed by a stranded copper conductor wrapped with a high-temperature resistant organic layer and then extruded with an elastomer insulating layer, and the conductor is a tinned copper wire continuously pulled and annealed by continuous cast and rolled high purity copper; and the shielding layer is a tinned round copper wire braided shielding layer, and the sheath is a halogen-free low-smoke flame-retardant polyurethane outer sheath. The product has the advantages of good corrosion resistance, electrical properties and mechanical properties, and long service life.

Description

The power cable of anti-mud

Technical field

The utility model relates to a kind of cable, is specifically related to a kind of power cable of anti-mud.

Background technology

See from the angle of using energy source; Country more and more payes attention to the exploitation of marine energy sources; The exploitation of marine energy sources is the major tasks project during " 12 " especially; Also with increasing, wherein the coastal waters is laid with the complete series cable device that is absolutely necessary to the input of relevant therewith offshore installation in country.Offshore oil exploitation will be the most important thing of marine energy sources exploitation, and the cable of used for oil platform must obligatoly install especially.The cable that oil platform top occasion is laid often will touch mud and greasy filth, and cable jacket receives the long-term corrosion of mud and greasy filth, and it is aging to quicken oversheath, reduces its machinery and physical property, reduces cable useful life; And use the not strong cable of this kind corrosion resistance for a long time, its danger is also than higher, thus the used for oil platform power cable to oversheath require high.Because cable uses and bears bigger non-homogeneous stress, adopts general conductor can't satisfy special mechanical performance and electric property requirement.But present cable can not satisfy the demands, and needs a kind of novel power cable of anti-mud.

The utility model content

The utility model technical problem to be solved provides a kind of power cable of anti-mud, and this product has good anti-corrosion, electric property and mechanical performance, long service life.

For solving the problems of the technologies described above, the utility model power cable of anti-mud comprises the outer sheath that is provided with of cable core and cable core; Said cable core forms by insulated wire cores is stranded, and the high flame retardant inserts is filled in the gap of cable core, the outer wrapped band of cable core; Band extrudes inner sheath outward, the outer woven shield of inner sheath, and screen extrudes oversheath outward; Said insulated wire cores extrudes elastic body insulated layer after by wrapped high temperature resistant organic layer on the twisted copper conductors and constitutes; Said conductor is the tinned wird that continuous casting and rolling Cu-CATH-1 Lian Lalian moves back, and said screen is zinc-plated round copper wire woven shield, and said sheath is a LSOH anti-flaming polyurethane oversheath.

The utlity model has following beneficial effect: conductor adopts continuous casting and rolling Cu-CATH-1 Lian Lalian strip tin copper cash, to obtain good pliable and tough cable conductor; High temperature resistantly organicly be with wrappedly, both can guarantee the fire resistant performance, can guarantee excellent electric property again; Insulating material adopts special elastic body material, and its performance meets the requirement of corresponding international standard; Adopt special fire-retardant packing material to fill between cable core, to reach the requirement of bunchy category-A burning test; Inner sheath adopts and can satisfy the cable-flame retardant performance demands, also and can reach the material of the requirement of the internal sheath mechanical strength of cable; Armour adopts zinc-plated round copper wire braiding structure, and the angle of weave through reasonable control braid in the production effectively raises the braid mechanical performance, and the control weaving quality guarantees that braid is smooth, do not have the silk of jumping, the particularly processing of joint; The oversheath of cable adopts LSOH anti-flaming urethane jacking, and very importantly the cable jacket material should satisfy the requirement of anti-slurry test.According to incompletely statistics, the annual demand of used for oil platform cable can reach quite a few thousand kilometers, and this kind cable also will obtain favor in occasions such as mine, land, land oil exploitations in addition.So believe this kind cable fabulous market prospects must be arranged.

Description of drawings

Fig. 1 is the structural representation of the utility model power cable of anti-mud;

Fig. 2 is the process chart that the utility model power cable of anti-mud is made;

Among the figure: 1-conductor, the high temperature resistant organic layer of 2-, 3-insulating barrier, 4-inserts, 5-band, 6-inner sheath, 7-screen, 8-sheath.

Embodiment

Wrapped high temperature resistant organic layer 2 on the tinned wird stranded conductor 1 that continuous casting and rolling Cu-CATH-1 Lian Lalian moves back extrudes elastic body insulated layer 3 and constitutes insulated wire cores outside high temperature resistant organic layer 2.Utilize stranding equipment with the stranded stranding of insulated wire cores, high flame retardant inserts 4 is filled in the gap of cable core, to guarantee the rounding of cable core.The outer wrapped band 5 of cable core, band extrudes inner sheath 6 outward, and inner sheath weaves zinc-plated round copper wire woven shield 7 outward, and screen extrudes LSOH anti-flaming polyurethane jacket 8 outward, constitutes the power cable of anti-mud.

Claims

1. the power cable of anti-mud comprises the outer sheath that is provided with of cable core and cable core, and said cable core forms by insulated wire cores is stranded; The high flame retardant inserts is filled in the gap of cable core, the outer wrapped band of cable core, and band extrudes inner sheath outward; The outer woven shield of inner sheath, screen extrudes oversheath outward, it is characterized in that; Said insulated wire cores extrudes elastic body insulated layer after by wrapped high temperature resistant organic layer on the twisted copper conductors and constitutes; Said conductor is the tinned wird that continuous casting and rolling Cu-CATH-1 Lian Lalian moves back, and said screen is zinc-plated round copper wire woven shield, and said sheath is the LSOH anti-flaming polyurethane jacket.
