Description

A kind of offshore oil device is used ethylene propylene rubber insulated cable

Technical field

The utility model relates to a kind of cable, and particularly a kind of offshore oil device is used ethylene propylene rubber insulated cable.

Background technology

The offshore oil device is because the space is narrow and small; Supporting cable needs particularly soft flexible, and traditional naval vessel and offshore oil device adopt crosslinked polyethylene to do insulation with cable more, but crosslinked polyethylene belongs to plastics; Material is harder; Cable is difficult to bending, causes or laying the space increases, or makes the cable curved transitions destroy cable performance.

The utility model content

The primary and foremost purpose of the utility model is, provides a kind of offshore oil device to use ethylene propylene rubber insulated cable, and is soft, is easy to bending, and insulation property and mechanical performance are good.

For solving above technical problem; The offshore oil device that the utility model provided is used ethylene propylene rubber insulated cable; Annealing tinned copper wire conductor extrudes ethylene propylene rubber insulated layer outward and constitutes insulated wire cores, the many mutually stranded formation cable cores of said insulated wire cores, and the periphery of said cable core is provided with inner covering; The periphery of said inner covering is coated with copper wire braiding armour; The periphery of said copper wire braiding armour is provided with the vertical covering of polyester belt, and the periphery of the vertical covering of said polyester belt is surrounded with fire-retardant Halogen band, and the periphery of said fire-retardant Halogen band is extruded with oil resistant mud sea water resistance rubber sheath.

With respect to prior art, the utility model has been obtained following beneficial effect: this cable adopts ethylene propylene rubber insulated layer soft, is easy to bending, and good insulation preformance; Inner covering is fixed cable core and is made the cable core rounding, and copper wire braiding armour provides mechanical protection to cable core; Copper wire braiding armour vertical covering of peripheral hardware polyester belt and fire-retardant Halogen band; Can avoid inner covering outer protective sleeve during through curing tube owing to receive high temperature pressure that fusion takes place; Be connected on insulated wire cores, armour and the rubber sheath thereby distortion is glutinous; Make distortion of the cable, rough and uneven in surface, can't peel off; Oil resistant mud sea water resistance rubber sheath forms the impermeability sheath, avoids inner armour weathering, corrosion, reduces mechanical performance.

As the preferred version of the utility model, said inner covering is the fire-retardant band lapping layer of non-hygroscopic.

As the preferred version of the utility model, the band nominal thickness of the fire-retardant band lapping layer of said non-hygroscopic is 0.22mm, and Duplication is 50% ~ 60%.

As another preferred version of the utility model, said inner covering extrudes layer for thermoplastics type's bittern-free flame-proof material.
