The utility model has the advantages of large intensity, slurry-proof, fire-resistant, and good shielding property.
Description
Technical field
The utility model relates to a kind of cable, the special cable that particularly a kind of drilling platforms is used.
Background technology
In the prior art, drilling platforms can produce a lot of mud in operation process, this mud is the compound that contains multiple components, can influence the use of cable, make that cable is aging easily, the burn into expansion, reduce its structural strength, in addition, the fire resistance of the cable that uses on drilling platforms requires height, and cable of the prior art has been difficult to reach requirement on combination property.
The utility model content
The purpose of this utility model provides a kind of drilling platforms with anti-mud fire-resisting cable, makes its intensity big, ability mud, and anti-flammability, shielding are good.
The purpose of this utility model is achieved in that a kind of drilling platforms is with preventing the mud fire-resisting cable, comprise heat curing-type polyolefin oversheath, be provided with the metal armouring layer in the oversheath, be provided with thermoplastics type's polyolefin inner sheath in the armour, be provided with total screen in the inner sheath, be provided with some screen units in total screen, between total screen and the screen unit and be provided with separator between the screen unit; Each screen unit comprises and is arranged at outer field sub-shield, be provided with at least one core cable in the sub-shield, each core cable wrap is drawn together and is arranged at the insulating barrier that outer field Halogen ethylene-propylene rubber is made, and is provided with mica tape in the insulating barrier, is provided with the soft conductor wire core of tin-coated copper in the mica tape.
The utility model adopts two-layer shielding, simultaneously, the metal armouring layer also plays certain shielding action, adopts separator can avoid the interference to cable of interference between the screen unit and external electromagnetic field between each screen, make its signal transmission more reliable, shield effectiveness is good; Separator can adopt the Halogen packing material, can make screen unit and inner sheath isolated by refractory material, the good flame resistance of cable; The metal armouring layer has been strengthened the intensity of cable greatly, and the setting of heat curing-type polyolefin oversheath makes the etch of its anti-mud; Therefore, the utility model intensity is big, ability mud, and anti-flammability, shielding are good; Can be applicable on the oil drilling platform.
As further improvement of the utility model, described total screen and sub-shield inboard are provided with leaky line.Because may occur between the screen being interrupted, the setting of revealing line can make the screen of interruption be connected as a single entity, and makes along the screen on the cable length direction to have identical electromotive force, has further reduced the interference of external electromagnetic field to cable.
