Description

The oil platform of anti-mud cable

Technical field

The utility model relates to a kind of cable, the particularly a kind of oil platform of anti-mud cable.

Background technology

Continuous development along with modern industry; The development and use of petroleum-based energy development is very fast, from land, coastal waters, off-lying sea oil platform quantity constantly increase, in oil exploitation; Need a large amount of cables that use; Since the special operation environment on the oil platform, solar radiation, high low temperature, mud-corrosion, salt fog and the corrosion of soda acid oil, anti-fire specific (special) requirements on the platform and pernicious gas toxicity etc.

As the cable that uses on the oil platform, need better insulation, LSOH anti-flaming, fire resistance, also need high-low temperature resistant, oil resistant, salt spray resistance and mud-corrosion resistant simultaneously, be difficult for aging characteristics, also need have higher mechanical strength.

Existing oil platform cable is 201020235006.4 like the patent No. of the applying date: 2010.06.24, and patent name is the oil platform cable; Though this structural cable has the fire prevention early warning; But do not have fire-resistant function, also do not have the mud-corrosion resistant performance, environment for use is limited; The particular surroundings that is unfavorable for mud-corrosion is used, and meets the need of market so should further promote its various performances to the oil platform cable.

The utility model content

The utility model technical problem to be solved provides the oil platform of the anti-mud cable that a kind of cable performance is adapted to oil platform more.

In order to solve above-mentioned technical problem, the technical scheme of the utility model is:

A kind of oil platform of anti-mud cable; Its ecto-entad is followed successively by the outer jacket of anti-mud, high flame retardant band, steel wire reinforced layer, oxygen barrier layer, copper wire woven shield and semiconductive waterstop; In said semiconductive waterstop, be provided with master core, core and control or keep watch on core; Said master core, control or supervision core are positioned at around the ground core, and said oxygen barrier layer material is a halogen-free and low-smoke flame-retardant polyolefin oxygen barrier material, and said outer jacket is a LSOH anti-flaming cross-linking radiation oversheath.

Said master core is made up of master core conductor, fire-resistant isinglass belt, insulating barrier and insulation screen from inside to outside successively, and in order to increase the fire resistance of cable, it is safer that cable is used, and the fire-resistant isinglass belt between said conductor and the insulating barrier is two layers.

Said ground core is made up of ground wire core conductor and wrapped semi-conductive tape in ground wire core conductor outside.

The utility model has increased by two layers of fire-resistant isinglass belt between conductor and insulating barrier, increased the fire resistance of cable, and it is safer that cable is used; Oxygen barrier layer adopts and extrudes halogen-free and low-smoke flame-retardant polyolefin oxygen barrier material; Improved the cable-flame retardant grade; Outer jacket has adopted the 105 ℃ of oil resistant LSOH anti-flaming of anti-mud cross-linking radiation protective cover materials; Strengthen the anti-environment capacity of cable, the various performances of cable are significantly improved, can satisfy special place user demands such as oil platform, harbour, naval vessel more broadly.

The utility model cable has advantages such as LSOH anti-flaming, fire-resistant, high strength, oil resistant, mud-corrosion resistant, shield effectiveness are good, possesses electric power, control and keeps watch on the one transfer function, is suitable for land and offshore oil platform lays use.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Accompanying drawing is the structural representation of the utility model.

Embodiment

Shown in accompanying drawing, the utility model oil platform of anti-mud cable is combined by power cable, control or monitoring cable, the master core of power cable, core form with control or the stranded stranding of monitoring cable.Master core adopts 3, control or monitoring cable, core adopt 1, concrete structure is:

Three master cores of power cable (insulated wire cores) are made up of master core conductor 1, fire-resistant isinglass belt 2, insulating barrier 3 and insulation screen 4 respectively; Fire-resistant isinglass belt 2 is wrapped in the outside of master core conductor 1, and the skin of fire-resistant isinglass belt 2 is extruded insulation layer 3 and insulation screen 4 successively.Master core conductor 1 adopts zinc-plated annealed copper skein silk system to form; Fire-resistant isinglass belt 2 adopts two plies wrapped, Duplication 50%, and insulating barrier 3 adopts double-layer coextrusion with insulation screen 4; High voltage withstanding second third electro-insulating rubber is adopted in insulation, can improve the electric property of cable.
