Abstract
The utility model discloses a variable frequency cable for an offshore oil platform. An insulating wire core is formed by a tinned copper conductor and a flame retardant cross-linked polyolefin insulating layer which is extruded at an outer layer of the conductor. Three insulating wire cores and three conductors are arranged alternately and are twisted to form a cable core. Flame retardant glass fiber ropes are filled at gaps of the cable core. The cable core and the glass fiber ropes are overlapped and wrapped by a wrapping layer. A tinned copper wire shielding layer is woven outside the wrapping layer. The shielding layer is wrapped by an inner lining layer. A tinned copper wire armored layer is woven outside the inner lining layer. An outermost layer of the cable is extruded by a polyolefin sheath layer. The cable has the performance indexes of low smoke, halogen-free, flame retardant and the like, and problems of oil resistance and mud resistance are solved at the same time.
Description
Technical field:
The utility model relates to a kind of frequency-changing 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 frequency-changing 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 provide a kind of frequency-changing cable for 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 frequency-changing cable for offshore oil platform, consist of insulated wire cores by tinned copper conductor with extruding in the outer field flame-proof cross-linking polyolefin insulation layer of conductor, three described insulated wire cores and three stranded formation cable cores of described conductor alternative arrangement, the cable core gap-fill has the flame retardant type glass cord;
At described cable core and the outside overlapping lapping layer that is surrounded with of glass cord, be woven with the tinned copper wire screen outside described lapping layer, inner covering is wrapped outside in described screen; Be woven with the tinned copper wire armour outside described inner covering, the outermost layer of cable is extruded with the polyolefin jacket layer.
Described lapping layer adopts the overlapping wrapped formation of one or more layers fire-retardant oxygen barrier band.
Described cross-sectional area of conductor is long-pending is 25-300mm
2
Described inner covering adopts the corrosion-resistant polyolefin of high flame resistance, low smoke Halogen to extrude formation.
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 25～300mm
2Adopt three to thoroughly do away with the edge cores and the stranded mode of three conductor alternative arrangements consists 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, lapping 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%.Be extruded with the corrosion-resistant polyolefin lining layer of high flame resistance, low smoke Halogen between screen and armour, have the effect of oil resistant, isolation and softening cable.
4, the coat layer of power cable 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, requirements that can the many corrosion of offshore oil platform equipment operational environment.
Description of drawings:
Fig. 1 is the utility model structural representation.
Number in the figure: 1 conductor, 2 insulating barriers, 3 glass cords, 4 lapping layers, 5 screens, 6 inner coverings, 7 armours, 8 restrictive coatings.
