Abstract
The invention discloses an offshore buoyant cable with a protection structure, which mainly comprises a cable body, wherein the outer side of the cable body is provided with an auxiliary conductor layer; and a protection layer made of a TPU (thermoplastic polyurethane) material with the minimum average thickness of 5.0mm is extruded and wrapped on the outer layer of the auxiliary conductor layer. The protection layer has the characteristics of corrosion resistance, mould prevention, oil resistance, moisture resistance and the like, and can protect the offshore buoyant cable to operate normally in a severe environment with a large temperature variation range; and additionally, in cable connection for the material, the connection modes of cold, hot and the like can be adopted for the sheath connection, the reparation of the cable is very convenient compared with rubber, and the cable can be ensured to operate stably for a long time.
Description
Technical field
The invention belongs to the power cable field, be specifically related to a kind of floating marine cable.
Background technology
The floating marine cable uses in the big environment of adverse circumstances and range of temperature; Need possess performances such as corrosion-resistant, anti-mould, oil resistant and humidity, the floating marine cable is at sea in the running; Often receive the impact of seawater; Also might suffer in the sea the damage of biological or other floating things, so the parts that cable directly bears this adverse circumstances are the outermost oversheaths of cable, and oversheath is the necessary condition that the protection cable is realized above-mentioned functions.
And the weak point that exists in the prior art is: poor-performings such as the rotproofness of cable, anti-mould, oil resistant, humidity; Oversheath does not reach certain thickness yet; Can't satisfy higher mechanical strength and toughness; So can not bear marine adverse circumstances, can not protect cable normally to move for a long time, thereby make the useful life of cable can not be permanent.
Summary of the invention
The purpose of this invention is to provide a kind of have thickness, mechanical strength height and flexibility be good, can bear marine adverse circumstances, and can make cable normally move, make the floating marine cable of cable long service life for a long time.
A kind of floating marine cable with protection structure of the present invention comprises cable body, outside cable body, is provided with and teaches the body layer, and described auxilliary conductor layer extrudes one deck cable covering outward.
Described auxilliary conductor layer 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.
It is polyurethane (TPU) material of 5.0mm that described cable covering adopts minimum average thickness.
After adopting technique scheme, the present invention has following beneficial effect:
The invention discloses a kind of floating marine cable with protection structure; Described cable covering adopts polyurethane (TPU) material; Can protect the floating marine cable in the big environment of adverse circumstances, range of temperature, can normally move, and have characteristics such as rotproofness, anti-mould, oil resistant, humidity.And as the jacket material of floating marine cable, mechanical strength that it is excellent and flexibility are that other material is incomparable.In addition, sheath can adopt connected modes such as hot and cold continuously when cable was made connection, and the reparation of cable is more very convenient than also with rubber phase, and can guarantee that cable can operation steady in a long-term.
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 protection structure of the present invention comprises the floating core chain splicing 1 of cable center, coats floating element 2 around the floating core chain splicing 1; 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; Outside auxilliary conductor layer 6, extrude protective layer 9 at last.
It is that polyurethane (TPU) material of 5.0mm is as cable covering that the present invention adopts minimum average thickness; Contrast between our the performance polyvinyl chloride (PVC), polyethylene (PE), chlorosulfonated polyethylene (CSM) and various elastomeric materials; Selected at aspects such as density, corrosion-resistant, anti-mould, oil resistant and humidities all very balanced at last; And as sheath material, the polyurethane (TPU) that excellent mechanical performance and flexibility are arranged is as floating marine cable protection layer material.This material can adopt connected modes such as hot and cold when sheath connects, the reparation of cable is more very convenient than also with rubber phase, and can guarantee that cable can operation steady in a long-term.Table 1 is the performance comparison of cable insulation material performance commonly used and TPU.
