Abstract
The invention discloses a marine floating cable with auxiliary conductor structures. The marine floating cable mainly comprises a cable body and a protective layer extruded on the outermost layer of the cable body, wherein the auxiliary conductors formed by a plurality of conductors and insulating layers coated outside the conductors are arranged on the outer side of the cable body. The auxiliary conductors of the marine floating cable disclosed by the invention are formed by multiple insulating conductors, and as the number of the auxiliary conductors is small, the increase of the insulating layers can contribute to the entire floating force of the cable and the reliability of the cable can be guaranteed; and the insulating conductors adopt thermoplastic vulcanizate (TPV) obtained by taking ethylene-propylene-diene monomer (EPDM) and polypropylene (PP) as base materials and vulcanizing the EPDM and the PP as an insulating material of the marine floating cable, and the TPV has the characteristics of flexibility, low density, good processing performance and recoverability, and is easy to bend.
Description
?
Technical field
The invention belongs to the power cable field, be specifically related to a kind of floating marine cable and teach body.
Background technology
At present, the proportion of the shared whole cable material therefor of floating marine whole cable structural requirement nonmetallic materials increases, and could improve the floatability of cable.And also do not have a kind of floating marine cable that under the prerequisite of the primary structure that does not influence whole cable, increases the proportion of nonmetallic materials in the prior art.
The range of choice of nonmetallic materials is more wide in range.But with regard to buoyant cable, the selection of insulating material has more characteristics: the one, must be soft, and be easy to bending; The 2nd, density is little, guarantees buoyancy; The 3rd, have good processing properties.And the deficiency that exists in the prior art is: through to cable industry commonly used nonmetallic materials like flexible PVC (PVC); Crosslinked polyethylene (XLPE); High density polyethylene (HDPE) (HDPE), ethylene propylene diene rubber material properties such as (EPDM) are analyzed, and think and all can not satisfy above three requirements simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of can the solution at the floating marine cable that does not change the problem that the proportion that increases nonmetallic materials under the integrally-built prerequisite and cable nonmetallic materials commonly used can not meet the demands.
A kind of floating marine cable of teaching body structure that has of the present invention, it mainly comprises cable body and be extruded in outermost protective layer, it is characterized in that: the cable body outside is provided with the guidance body.
Described guidance body is by several conductors and be coated on the outer insulating barrier of conductor and constitute.
Described cable body by the floating core chain splicing that is positioned at cable center, be coated on plunger core group around the floating core chain splicing, be arranged on the outer sealant of plunger core group, be stranded in the leading body on the sealant and the inner sheath that is coated on the leading body is formed.
The insulating material that said guidance body adopts is to be base-material and the thermoplastic rubber's material (TPV) that makes its sulfuration with EPDM and polypropylene (PP).
Beneficial effect of the present invention is:
The composition that the present invention relates to is taught and is coated one deck insulating material on each the root monofilament on the body, increases insulating barrier and contribute for whole cable buoyancy to some extent, and guarantee factor such as its reliability, and can not influence the overall structure of cable.And insulating material adopts a kind of to be base-material and the thermoplastic rubber material (TPV) that makes its sulfuration with EPDM and polypropylene (PP), to have three kinds of performances simultaneously: the one, and softness is easy to bending; The 2nd, density is little, guarantees buoyancy; The 3rd, have good processing properties, and recyclable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; A kind of floating marine cable of teaching body structure that has of the present invention comprises the floating core chain splicing 1 of cable center coating floating element 2 around it; The floating element 2 outer sealants 3 that are provided with; Leading body 4 is stranded on the sealant 3, on leading body 4, coats inner sheath 5, twines on the inner sheath 5 and teaches body 6; Teach body 6 to form by several conductors 7 and the insulating barrier 8 that is coated on the conductor 7; Teach the body 6 outer protective layers 9 that extrude.
The composition that the present invention relates to is taught and is coated one deck insulating material on each the root monofilament on the body, is feasible, increases insulating barrier and contribute for whole cable buoyancy to some extent, and guarantee factor such as its reliability, and also can not influence the overall structure of cable.It is base-material and the thermoplastic rubber material (TPV) that makes its sulfuration with EPDM and polypropylene (PP) that insulating material adopts a kind of.It has following performance simultaneously: the one, and soft, be easy to bending; The 2nd, density should be little, guarantees buoyancy; The 3rd, have good processing properties, and recyclable.As: table 1 is the performance comparison of cable insulation material performance commonly used and TPV.
