Abstract
The utility model discloses a low-voltage suspender cable for a harbor. The low-voltage suspender cable comprises six main conductors, wherein each conductor is wrapped in an insulating layer; wrapped in the insulating layers, the main conductors are then intertwisted and bundled, wherein in the intertwisting and bundling process, steel cores are added for strengthening; a cable core after bundling is wrapped in a belting layer, wherein flame-retardant fiber glass ropes as a filling layer are arranged between the belting layer and the insulating layers; an inner lining layer and an armored layer are wrapped around the belting layer, wherein the armored layer is formed by braiding galvanizing steel wires, and the braiding density is no less than 90%; and a high-flame-retardation low-smoke halogen-free corrosion-resisting polyolefin sheath layer is wrapped around the armored layer. The low-voltage suspender cable of the utility model can meet required fire retardant, wear resistant, bending and torsion resistant and other performance indexes of harbor suspender cables, and at the same time solves moistureproof and anticorrosion problems.
Description
Technical field
The utility model relates to cable industry, is specifically related to a kind of harbour low pressure hoist cable.
Background technology
The port construction cable mainly is harbour construction with power transmission and distribution power cable, the interim distribution cable in building site and light conduits, telecommunication cable, harbour machinery with cable etc.According to the natural conditions in building site, harbour, require used cable to have anti-ly to pull, the mechanical performance such as tractive, impact, require simultaneously safe and reliable leakproof.It is reported that except the high voltage supply circuit with the circuit that fixing planning has been laid, the cable major part of using on the building site is cabtyre cable.
Traditional port cable structure is single, and function singleness can not satisfy present stage harbour environment for use, is a topic that is difficult to resolve for wear-resisting in the actual working environment, anti-distortion problem always.
The utility model content
The utility model provides a kind of harbour low pressure hoist cable, satisfies harbour hoisting device cable and has the performance index such as fire-retardant, wear-resisting, anti-flexion torsion, and this cable has also solved moistureproof, Anticorrosion Problems.
Scheme of the present utility model is as follows: a kind of harbour low pressure hoist cable, include six roots of sensation leading body, the conductor outside is enclosed with respectively insulating barrier, stranded bunchy behind the wrap insulate layer, adding steel core in the stranded bunchy process strengthens, the cable core outside is enclosed with belting layer behind the bunchy, be provided with the flame retardant type glass cord between described belting layer and the insulating barrier as packed layer, the described belting layer outside is enclosed with inner covering, armour, described armour adopts the zinc-coated wire braiding, count is not less than 90%, and the described armour outside is enclosed with the corrosion-resistant polyolefin jacket layer of high flame resistance, low smoke Halogen.
Described insulating layer material is the flame-proof cross-linking polyolefin.
Described belting layer adopts the overlapping wrapped formation of one or more layers fire-retardant oxygen barrier band.
Described inner covering adopts the corrosion-resistant polyolefin of high flame resistance, low smoke Halogen to extrude formation.
Conductor of the present utility model, insulation, sheath material all use the material of mechanical performance excellence in the material of the same type, material has at first been given prominence to the characteristics of the excellence of good mechanical property, secondly material is not easy to wear, and the anti-pressure and abrasion-proof performance is outstanding, and has good electric property; The steel core of cable is strengthened the mechanical property that the further reinforced layer of structure is strengthened cable, and halogen gas, gas pH value of water solution and the conductivity of overflowing during the cable material burning are low, have the low-corrosiveness energy; It is few to generate smog during cable fire, and possesses the performances such as wear-resisting, anti-tear, oil resistant, anti-ozone, high flame retardant.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of harbour low pressure hoist cable comprises that it is 10～120mm that six roots of sensation leading body 1, cross-sectional area of conductor amass
2 Insulating barrier 2, conductor 1 outside is enclosed with respectively insulating barrier 2, wrap insulate layer 2 rear stranded bunchy, stranded process is added steel core 3 and is strengthened, the cable core outside is enclosed with belting layer 4 behind the bunchy, be provided with the flame retardant type glass cord between described belting layer and the insulating barrier as packed layer 5, belting layer 4 outsides are enclosed with inner covering 6, armour 7, armour 7 adopts the tinned copper wire braiding, count is not less than 90%, armour 7 outsides are enclosed with the corrosion-resistant polyolefin jacket layer 8 of high flame resistance, low smoke Halogen, insulating barrier 2 materials are the flame-proof cross-linking polyolefin, and belting layer 3 adopts the overlapping wrapped formation of one or more layers band, and inner covering 6 adopts the corrosion-resistant polyolefine material of high flame resistance, low smoke Halogen to extrude formation.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
