Abstract

The utility model discloses a low-voltage reel flexible cable for a harbor. The low-voltage reel flexible cable comprises three main conductors and three auxiliary conductors, wherein each conductor is wrapped in an insulating layer; after wrapped in the insulating layers, the conductors in different sizes are uniformly arranged in a stagger manner and are intertwisted to form a bundle; the bundle of cable core 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; the belting layer is wrapped in a shielding layer, wherein the shielding layer is of a mixed braiding structure of nylon and tin-coated copper wires, and the braiding density is no less than 90%; and the shielding layer is wrapped in a high-flame-retardation low-smoke halogen-free corrosion-resisting chloroprene rubber sheath layer. The low-voltage reel flexible cable of the utility model can meet required fire retardant, wear resistant, bending and torsion resistant and other performance indexes of harbor low-voltage reel cables, and at the same time solves moistureproof and anticorrosion problems.

Description

A kind of harbour low pressure reel flexible cable

Technical field

The utility model relates to cable industry, is specifically related to a kind of harbour low pressure reel flexible 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 single, function singleness of port cable structure 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 with low pressure reel flexible cable, has both satisfied harbour low pressure reel cable and has had the performance index such as fire-retardant, wear-resisting, anti-flexion torsion, has also solved moistureproof, Anticorrosion Problems.

Scheme of the present utility model is as follows: a kind of harbour low pressure reel flexible cable, comprise three leading bodies and three auxiliary-conductors, the described conductor outside is enclosed with respectively insulating barrier, the even staggered stranded bunchy of big or small core behind the wrap insulate layer, 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, described belting layer outer wrapping screen, described screen adopts nylon and tinned copper wire mixed weaving structure, count is not less than 90%, and the described screen outside is enclosed with the corrosion-resistant chloroprene rubber sheath layer of high flame resistance, low smoke Halogen.

Described insulating layer material is inflaming retarding ethylene propylene rubber.

Described belting layer adopts low smoke and zero halogen oxygen barrier band.

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 soft, that mechanical performance is excellent, secondly material is not easy to wear, and the anti-pressure and abrasion-proof performance is outstanding, and has good electric property; The mixed weaving layer of cable adopts nylon and tinned copper wire mixed weaving, both played the effect that the shielding outer signals is disturbed, can strengthen by the nylon reinforced layer again the mechanical property of cable, 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 comprises that with low pressure reel flexible cable it is 1.5～25mm that three leading bodies 1, cross-sectional area of conductor amass ²Three auxiliary-conductors 2, insulating barrier 3, three leading bodies 1 and three auxiliary-conductor 2 outsides are enclosed with respectively insulating barrier 3, wrap insulate layer 3 rear big or small core are staggered stranded bunchy evenly, 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, described belting layer outer wrapping screen 6, described screen 6 adopts nylon and tinned copper wire mixed weaving structure, count is not less than 90%, and described screen 6 outsides are enclosed with the corrosion-resistant chloroprene rubber sheath layer 7 of high flame resistance, low smoke Halogen.

Described insulating barrier 3 materials are inflaming retarding ethylene propylene rubber.

Described belting layer 4 adopts low smoke and zero halogen oxygen barrier band.

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.
