Abstract
The invention discloses an offshore floating cable with high current-carrying capacity. A floating element is arranged in the center of the cable, a main conductor is externally stranded with the floating element, an inner jacket encapsulates the main conductor, an auxiliary conductor layer is arranged on the outer side of the inner jacket, and a protection layer is extruded on the auxiliary conductor layer. The floating element useing a foaming type rubber plastic material has the following characteristics of low density, light weight, flexibility, easiness in bending and good processability. The floating element is arranged in the center of the cable, so as to prevent the current-carrying capacity of the cable from being reduced due to large whole heat resistance resulted from large heat resistance which is brought by arranging the floating element on the outer layer of the cable, thus the technology is easy to process, the material is easy to obtain, and the price is low, so as to save the manufacture cost.
Description
?
Technical field
The invention belongs to the power cable field, be specifically related to a kind of floating marine cable of high current-carrying capacity.
Background technology
At present, the position of the floating element of floating marine cable in cable is if become the normal cable design to consider; Conductor should be at the center; Though conductor structure is therefore more stable,, certainly will cause overall thermal resistance to become big because the floating element thermal resistance is bigger; Cause current-carrying capacity of cable to reduce, be unfavorable for very much the current delivery of cable.Floating element is that can the decision cable swim in the key element of the water surface, it select the floating functional parameter that not only determines cable for use, and farthest determined the manufacturing process of cable.Floating element is selected special material and hollow metal spare for use always at present, and not only cost is very high, processes also pretty troublesome.
Summary of the invention
The purpose of this invention is to provide that a kind of floatability is good, low price, be prone to the floating marine cable of the high current-carrying capacity of processing.
The floating marine cable of a kind of high current-carrying capacity according to the invention, the center of cable is provided with floating element, stranded leading body outside floating element, the inner sheath that on leading body, coats, the inner sheath outside is provided with auxilliary conductor layer, and auxilliary conductor layer extrudes protective layer outward.
Said floating element 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 and form.
Said floating element adopts the expansion type rubber-plastics material.
Beneficial effect of the present invention is:
The present invention is placed on the center of cable with floating element, and floating element is provided with conductor outward, has so just avoided floating element to be positioned at skin, the problem that the current-carrying capacity of cable that causes greatly because of its thermal resistance reduces.Floating element adopts the expansion type rubber-plastics material, and its rubber-plastics material is in normal cable manufacture of materials process, to add blowing agent, makes to occur bubble in the floating element, makes it weight saving, increases its floatability.This processes is easy, and material also is easy to obtain, low price, thus save manufacturing cost.
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 with floating structure of the present invention comprises the floating core chain splicing 1 of cable center, coats 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 auxilliary conductor layer 6 on the inner sheath 5; Auxilliary conductor layer 6 is made up of several conductors 7 and the insulating barrier 8 that is coated on the conductor 7; The auxilliary conductor layer 6 outer protective layers 9 that extrude.
The invention provides a kind of version and implementation method of floating marine cable floating element; The above only is a preferred implementation method of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
