Abstract
The invention provides a special high-frequency and energy-saving communication flexible cable for a ship, and relates to the technical field of production of cables. The special high-frequency and energy-saving communication flexible cable for the ship comprises six strands of insulating conductors which are twisted with each other; a lapping layer, an polyolefin inner bushing layer, a tinned copper wire braiding armor layer and a polyolefin outer bushing layer are sequentially arranged outside the twisted insulating conductors; fillers are placed between the insulating conductors and the lapping layer; each strand of insulating conductors comprises a tinned copper wire conductive core wire; and a crosslinked polyethylene insulating layer is wrapped outside each tinned copper wire conductive core wire. The special high-frequency and energy-saving communication flexible cable for the ship is low in smoke, halogen free, flame retarded, corrosion resistant, and interference resistant, and is applicable to telecommunication equipment, electrical instruments, and signal transmission and control systems of various information processing devices in the ship and overwater floating buildings.
Description
Technical field
The present invention relates to the cable manufacture technology field.
Background technology
Because the environment more complicated of marine and ship's navigation, safe class is had relatively high expectations when laying installation, and to useful life of cable, anti-electromagnetic interference capability, the low smoke and zero halogen performance, anti-flammabilitys etc. all have higher requirements.At present telecommunication cable commonly used can not be satisfied the demand, and its water proofing property, corrosion resistance, anti-interference, high temperature resistant and oil resistance is relatively poor, and be subjected to external force to affect easy damage, thereby affect useful life and effect, and maintenance difficult.
Summary of the invention
The object of the invention is to provide a kind of strong anti-interference performance, high temperature resistant, oil resistant, the good marine high-frequency energy-saving special flexible communication cable of performance such as anticorrosion.
The present invention includes six strands of mutual stranded insulated electric conductors, outside described stranded insulated electric conductor, set gradually jacket layer in lapping layer, the polyolefin, tinned copper wire braiding armour and polyolefin jacket layer; Between described insulated electric conductor and lapping layer, inserts is set; Described per share insulated electric conductor comprises respectively the tin-coated copper conductor wire core, at the crosslinked polyetylene insulated layer of described tin-coated copper conductor wire core outer wrapping.
The present invention is insulation resistance constant 〉=3670M Ω .km in the time of 20 ℃, and the insulation resistance constant is 3.67M Ω .km under the working temperature.The minimum 300M Ω .km of seawater corrosion resistance insulation resistance (20 ℃), shielding insulation resistance, individually shielded line is to reaching the minimum 1M Ω of insulation resistance between the bulk shielding. Km, the minimum 0.25M Ω of the insulation resistance between any shielding and the armouring. km.The present invention by automatic takeup, has controlled the tightness degree of stranded core at cabling process effectively.The present invention has good low cigarette, Halogen, fire-retardant, corrosion resistant, the function such as anti-interference, is applicable to telecommunication apparatus in naval vessel and the Overwater floating building, signal transmission and the control system of electrical instrumentation and various information processors.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is provided with six strands of mutual stranded insulated electric conductors, sets gradually jacket layer 4 in lapping layer 3, the polyolefin, tinned copper wire braiding armour 5 and polyolefin jacket layer 6 outside stranded insulated electric conductor; Inserts 7 is set between insulated electric conductor and lapping layer; Per share insulated electric conductor comprises respectively tin-coated copper conductor wire core 1, at the crosslinked polyetylene insulated layer 2 of tin-coated copper conductor wire core outer wrapping.
