Abstract
The utility model discloses a power cable for an offshore oil platform. An insulating wire core is formed by a conductor and a cross-linked polyolefin insulating layer which is extruded at an outer layer of the conductor. A sectional area of the conductor is 15 square centimeters to 300 square centimeters. Three insulated wire cores are stranded to be a cable core. Ropes are filled at gaps of the cable core. The cable core and the glass fiber ropes are overlapped and wrapped by a belting layer formed by a flame retardant oxygen barrier belt. An outer layer of the belting layer is extruded by an inner lining layer and is woven with a tinned copper wire armored layer. An outermost layer of the cable is extruded by a polyolefin outer sheath. The cable has the performance indexes of low smoke, halogen-free, flame retardant and the like, and problems of moisture proof, corrosion resistance, oil resistance and mud resistance are solved.
Description
Technical field:
The utility model relates to a kind of power cable for offshore oil platform.
Background technology:
The development of China's oil platform cable is started in the eighties in last century.Under the springing up of exploitation China offshore petroleum resources upsurge, Some Domestic large-sized cable factory all once developed offshore oil platform cable.But the macrotype platform in China's marine site probing and oil recovery was all state's outer platform basically at that time, and state's outer platform General Requirements uses the platform cable of foreign country, and therefore domestic cable is served as reasons with quality dissatisfaction and kept outside of the door.
The environment of working due to cable for petroleum flat has that greasy dirt is heavy, mud is many, therefore traditional offshore oil platform with power cable how to overcome oil resistant, anti-mud problem is a technical barrier always.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to be provided for the power cable of offshore oil platform, has low cigarette, Halogen, the performance index such as fire-retardant, has solved also simultaneously that oil resistant is dirty, anti-mud problem.
The utility model technical solution problem adopts following technical scheme:
A kind of power cable for offshore oil platform consists of insulated wire cores by conductor with extruding in the outer field cross-linked polyolefin insulating barrier of described conductor, and the sectional area of described conductor is 15-300mm
2, three described insulated wire cores are stranded is cable conductor, at described cable core gap-fill, glass cord is arranged;
At described cable core and the outside overlapping belting layer that is surrounded with fire-retardant oxygen barrier band formation of glass cord, described belting layer skin is extruded with inner covering, is woven with the tinned copper wire armour, and the outermost layer of cable is extruded with the polyolefin oversheath.
Described inner covering is extruded outside described belting layer by the corrosion-resistant polyolefin of high flame resistance, low smoke Halogen and consists of.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model cable conductor adopts the 2nd kind of tinned copper conductor of stipulating in GB/T3956.Cross-sectional area of conductor is generally 15-300mm
2, adopt the three stranded modes of eradication edge core to consist of cable core, not only be easy to lay, have simultaneously good mechanical performance, more be applicable to oil platform drillng operation demand, and tinned conductor can effectively prevent oxidation, the passivation of marine dampness lower conductor.
2, insulating barrier is the flame-proof cross-linking polyolefin.This material has physics, chemical property and the high and low temperature resistance of excellent electrical insulation capability, excellence; Excellent flexibility performance and anti-wear performance; Excellent low cigarette, Halogen characteristic.
3, belting layer adopts fire-retardant oxygen barrier band overlapping wrapped, can be at starvation under ignition condition, and fire-retardant.Screen and armour adopt the tinned copper wire braiding, and it has the mechanical protection effect concurrently, and count is according to IEC 60092-350 standard code, and count is not less than 90%.
4, cable jacket adopts the corrosion-resistant polyolefin of high flame resistance, low smoke Halogen as the sheath material of cable.Low temperature resistant reaching-30 ℃ after this material modification, and possess the performances such as wear-resisting, anti-tear, oil resistant, anti-ozone, corrosion-resistant, high flame retardant, can satisfy the requirements of the many corrosion of offshore oil platform equipment operational environment.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 conductor, 2 insulating barriers, 3 glass cords, 4 belting layers, 5 inner coverings, 6 armours, 7 oversheaths.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1, the power cable that is used for offshore oil platform of the present embodiment consists of insulated wire cores by conductor 1 with extruding in the outer field cross-linked polyolefin insulating barrier 2 of conductor 1, and the sectional area of conductor is 15-300mm
2, thoroughly do away with the edge core stranded by three and be cable conductor, at the cable core gap-fill, glass cord 3 arranged, guarantee the roundness of cable.
Be surrounded with the belting layer 4 that fire-retardant oxygen barrier band consists of cable core and glass cord 3 is outside overlapping, belting layer 4 skins are extruded with inner covering 5, inner covering 5 and are extruded in described belting layer 4 is outer by the corrosion-resistant polyolefin of high flame resistance, low smoke Halogen and consist of.Be woven with tinned copper wire armour 6 in the inner covering outside, the outermost layer of cable is extruded with polyolefin oversheath 7.
