Abstract
The invention discloses a flexible cable for a port. The cable comprises conductors, insulation layers and an outer sheath; each conductor is formed by twisting a plurality of tinned copper conduction wires; an inflaming retarding ethylene propylene rubber insulation layer wraps each conductor; a nylon shielding layer and a tinned copper wire shielding layer respectively wrap the insulation layer to form one cable core; a wrapping belt layer wraps three stranded cable cores; inflaming retarding glass fiber ropes are arranged among the cable cores and the wrapping belt layer to be used as a filling layer; a nylon shielding layer and a tinned copper wire shielding layer are arranged outside the wrapping belt layer. The sheath layer made of a high-inflaming retarding, low smoke, no halogen and corrosion resistance neoprene rubber material wraps the tinned copper wire shielding layer. Insulation cable cores are arranged among the three cable cores. A nylon rope is arranged in the center of the cable. The flexible cable has low corrosion performance, the smoke during the burning of the cable is less, and the cable has the performances such as wear resistance, tear resistance, oil resistance, ozone resistance and high inflaming retarding.
Description
Technical field
The present invention relates to cable industry, be specifically related to a kind of harbour flexible cable.
background technology
Port construction cable is mainly harbour construction power transmission and distribution power cable, the interim distribution cable in building site and light conduits, telecommunication cable, harbour machinery cable etc.According to the natural conditions in building site, harbour, require cable used to have resistance toly to pull, the mechanical performance such as tractive, impact, require safe and reliable leakproof simultaneously.It is reported, except high voltage supply circuit with the circuit that fixing planning has been laid, the cable major part of using on building site is cabtyre cable.
Traditional harbour is single with soft cable structure, function singleness, can not meet present stage harbour environment for use, is a topic being difficult to resolve for wear-resisting in actual working environment, anti-distortion problem always.
Summary of the invention
The invention provides a kind of harbour flexible cable, both met the performance index such as fire-retardant, wear-resisting, resistance to flexion torsion, also there is protection against the tide, anticorrosion advantage.
The solution of the present invention is as follows: a kind of harbour flexible cable, comprise conductor, insulating barrier and oversheath, described conductor is by some stranded the forming of tin-coated copper seal wire, the outer wrapped inflaming retarding ethylene propylene rubber insulating barrier of described conductor, the outer wrapped nylon screen respectively of described insulating barrier and tinned copper wire screen form core, three belting layers that the stranded rear wrapped employing low smoke and zero halogen oxygen barrier band of core is made, are provided with flame retardant type glass cord as packed layer between described core and belting layer; Described belting layer is also provided with nylon screen and tinned copper wire screen outward, and described tinned copper wire screen is wrapped with the restrictive coating that the corrosion-resistant chloroprene rubber material of high flame resistance, low smoke Halogen is made; Between three described cores, be also provided with insulated wire cores, described insulated wire cores is made up of the wrapped inflaming retarding ethylene propylene rubber insulating barrier of conductor; Cable center is provided with nylon rope.
Further, described conductor is silver-plated copper conductor, is formed by 10-30 thigh silver-plated copper wire stranding.
Further, described nylon screen and tinned copper wire shielding thickness interval are 1-6mm.
Conductor of the present invention, insulation, sheath material all use the material of mechanical performance excellence in material of the same type, and material is not easy to wear, and anti-pressure and abrasion-proof performance is outstanding, and has good electric property; The screen of cable adopts nylon and two kinds of materials of tinned copper wire, both played the effect that shielding outer signals is disturbed, the mechanical property that can strengthen by nylon reinforced layer again cable, halogen gas, gas pH value of water solution and the conductivity of when cable material burning, overflowing are low, have low-corrosiveness energy; When cable fire, generate smog few, and possess the performances such as wear-resisting, anti-tear, oil resistant, resistance to ozone, high flame retardant.
brief description of the drawings
Fig. 1 is structural representation of the present invention.
embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of harbour flexible cable, comprise conductor 1, insulating barrier 2 and restrictive coating, described conductor 1 is by some stranded the forming of tin-coated copper seal wire, the outer wrapped inflaming retarding ethylene propylene rubber insulating barrier 2 of described conductor 1,4 layers of formation core of the described wrapped nylon screen 3 of the outer difference of insulating barrier 2 and tinned copper wire shielding, three belting layers 5 that the stranded rear wrapped employing low smoke and zero halogen oxygen barrier band of core is made, are provided with flame retardant type glass cord as packed layer between described core and belting layer; Described belting layer 5 is outer is also provided with nylon screen II 6 and tinned copper wire screen II 7, and described tinned copper wire screen 7 is wrapped with the restrictive coating 8 that the corrosion-resistant chloroprene rubber material of high flame resistance, low smoke Halogen is made; Between three described cores, be also provided with insulated wire cores 9, described insulated wire cores 9 is made up of the wrapped inflaming retarding ethylene propylene rubber insulating barrier of conductor; Cable center is provided with nylon rope 10.
Described conductor 1 is silver-plated copper conductor, is formed by 10-30 thigh silver-plated copper wire stranding.Between described nylon screen 3 and tinned copper wire screen 4 caliper zones, be 1-6mm.
The screen of cable of the present invention adopts nylon and two kinds of materials of tinned copper wire, both played the effect that shielding outer signals is disturbed, can strengthen by nylon reinforced layer again the mechanical property of cable, halogen gas, gas pH value of water solution and the conductivity of when cable material burning, overflowing are low, have low-corrosiveness energy; When cable fire, generate smog few, and possess the performances such as wear-resisting, anti-tear, oil resistant, resistance to ozone, high flame retardant.
Although above the specific embodiment of the present invention 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 invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
