Description

A kind of umbilical cable

Technical field

The utility model relates to a kind of power and control composite cable, relates in particular to a kind of umbilical cable, belongs to technical field of electric wires and cables.

Background technology

Along with people's deepens continuously more and more advanced with engineering to understanding naturally; Coastal waters and deep water exploitation, oil exploration and fields such as exploitation, space probation are flourish; The appearance in these novel fields needs the umbilical cable of special purpose to connect line for its equipment.Umbilical cable is exactly often to be designed to one to transmission electric wires such as power, data, detections.Because the environment in the use field of umbilical cable is very severe, harshness often; Simultaneously the cable that uses is also had performance index requirements such as volume is as far as possible little, weight is light as far as possible, intensity is high as far as possible, flexibility is as well as possible, function is powerful as far as possible, the general category cable can't obtain these requirements.But do not aim at the umbilical cable that adapts to this requirement in the prior art.

Summary of the invention

The utility model is for avoiding above-mentioned existing in prior technology weak point; The umbilical cable that provide that a kind of volume is little, in light weight, intensity is high, flexibility good, powerful collection power, signal, observing and controlling is transmitted as one, special in adapting to abominable, harsh environment for use.

The utility model technical solution problem adopts following technical scheme:

The design feature of the utility model umbilical cable be power line core conductor, ground wire core conductor and control line core conductor respectively by many stranded formation of tinned copper wire, on power line core conductor and ground wire core conductor, extrude the insulating barrier that forms by the ethylene-propylene rubber compound separately to constitute power insulated wire cores and ground insulated wire cores respectively; On the control line core conductor, extrude the insulating barrier that forms with perfluoroethylene-propylene F46 and constitute the control insulated wire cores; To be spaced stranded stranding formation cable core in three power insulated wire cores and three ground insulated wire cores; Outside cable core; What set gradually from inside to outside is total screen of constituting of the belting layer through the wrapped formation of double-layer overlapping, the inner restrictive coating that extrudes formation, braiding, the external sheath layer that extrudes formation; Between total screen and external sheath layer, respectively control insulated wire cores, between each adjacent control insulated wire cores, be placed with gasket for packing along the even setting of circumference.

The design feature of the utility model umbilical cable also is:

Said master core conductor, ground wire core conductor and control line core conductor are the 5th type or the 6th type of tin-coated copper conductor.

Said ground wire core conductor area of section is not less than the sixth of power line core conductor area of section.

Said three power insulated wire cores and three ground insulated wire cores symmetry and be spaced the formation cable core.

Said total screen adopts bare copper wire or tinned copper wire braiding to form.

Said gasket for packing is consistent with control insulated wire cores external diameter.

Said external sheath layer adopts haloflex, neoprene rubber or chlorosulfonated polyethylene material to extrude formation.

Compared with present technology, the utility model beneficial effect is embodied in:

1, the utlity model has better flexibility, be convenient to flexibly, frequent moving, tinned copper wire can effectively prevent conductor oxidized increase that causes resistance in the utilization process, causes contact wave or heating and causes fire to take place;

2, the utility model cable ground wire core conductor area is not less than the master core sixth, and it is half that the gross area is not less than the main cross section, increased the cable loop ampacity, guarantees the fail safe of cable;

3, three master cores of the utility model and three ground core symmetries are spaced, and have improved Electro Magnetic Compatibility, than the better electrical property of quad;

4, the total screen of the utility model adopts bare copper wire or tinned copper wire braiding, has improved bending, the softness of cable, prevents electromagnetism mutual interference mutually between power line and the control line on the other hand;

5, the utility model gasket for packing is consistent with control insulated wire cores external diameter, makes the construction of cable more stable;

6, the utility model external sheath layer adopts haloflex or materials such as neoprene rubber, chlorosulfonated polyethylene to extrude formation, and its type material has higher mechanical properties and fire resistance, satisfies the rugged environment requirement.
