Abstract
The utility model discloses an offshore oil platform non-halogen low-smoke flame-retardant oil-resistant meter cable, which comprises a cable core and an outer sheath; the inside of the cable core isprovided with a plurality of double-wire twisted-pair groups which are covered with polyester tape layer; a cable core belting layer, a flame-retardant layer, an inner protective layer are in turn arranged between the cable core and the outer sheath; a double-wire twisted-pair group shield layer and a lead wire are arranged outside the polyester tape layer of the double-wire twisted-pair group; the cable core shield layer and another lead wire are arranged between the flame-retardant layer and the inner protective layer at the outside the cable core; and an armoring layer is arranged between the inner protective layer and the outer sheath. The offshore oil platform non-halogen low-smoke flame-retardant oil-resistant meter cable has good flexibility, and good shielding performance, good flame-retardant performance, good fire resistance performance, and good oil-retardant performance; and can ensure the normal use of the cable in the harsh operating environment at the offshore oil platform without easy damage.
Description
Technical field
The utility model relates to a kind of instrument cable, especially the instrument cable used of offshore oil platform.
Background technology
The operating environment of offshore oil platform is abominable, and cable very easily is subjected to the corrosion of oils and saliferous aqueous vapor, requires cable that good oil resistant decay resistance is arranged; The space is limited on the oil platform, and cable laying is subjected to certain restriction, and instrument cable lays with other cable, is subjected to the interference of electromagnetic field easily, requires the flexibility of cable good, and has good shielding properties; The oil platform cost is high, and is densely populated, requires cable to have characteristics such as fire-retardant, fire-resistant, in case breaking out of fire, cable can normally stably be worked, and is convenient to personnel's evacuation and rescue.The existing instrument cable that is used for offshore oil platform is difficult to adapt to these requirements, in use damages easily.
Summary of the invention
In order to overcome the deficiency of the instrument cable that existing offshore oil platform uses, the utility model provides a kind of offshore oil platform LSOH anti-flaming oil resistant instrument cable, can adapt to the abominable operating environment of offshore oil platform, and is not fragile.
A kind of offshore oil platform LSOH anti-flaming oil resistant instrument cable that the utility model provides comprises cable core and oversheath, the two-conductor line pair twist group that has several outsourcing polyester belts in the cable core, between cable core and oversheath, set gradually cable core belting layer, flame-retardant layer, sheath, polyester belt peripheral hardware in two-conductor line pair twist group has two-conductor line pair twist set of shield layer and drainage thread, be provided with cable core screen and drainage thread between flame-retardant layer outside cable core and the sheath, between sheath and oversheath, be provided with armour.
The conductor of every lead of the present utility model can be made through synnema with after twisting again with the oxygen-free copper monofilament, and the insulating barrier of lead can be made with insulating material of polyethylene; The outer screen of the polyester belt of two-conductor line pair twist group can be made (aluminium is towards interior) with the single face aluminium-plastic tape; The cable core belting layer can be made with polyester belt; Flame-retardant layer can be made with glass tape; The cable core screen can be made (aluminium is towards interior) with the single face aluminium-plastic tape; Sheath can be made with the halogen-free and low-smoke flame-retardant polyolefin material; Armour can form with the finer wire braiding; Oversheath is made with LSOH anti-flaming oil resistant cross-linking radiation polyolefin jacket material.
The beneficial effects of the utility model are: the cable flexibility is good, has good shielding, fire-retardant, fire-resistant, oil resistance, can guarantee the normal use of cable at sea in the abominable operating environment of oil platform, and is not fragile.
