Abstract
The invention discloses a marine fire-resistant frequency-variable cable which comprises main line core conductors and grounding lines, wherein each main line core conductor is composed through tight pressing and wrapping of two mutually twisted silver-plated copper conductors and one aluminum-plastic filling rod; the main line core conductors and the grounding lines are coated by an insulating protective layer; the three main line core conductors and three grounding lines which are distributed uniformly on the outer sides of the conductors are pressed and wrapped to form a cable core; and a control line core is disposed at the center of the cable core, and outside of the cable core is successively equipped with an inner liner layer, a shielding layer, an armor layer, a waterproof layer, a sheath layer and a fireproof protective layer. The cable disclosed by the invention mainly has the advantages that the cable is resistant to water, wear, moisture, oil, fire and high temperature; the cable can be used at temperatures between -40 DEG C and 200 DEG C; the cable has good shielding performance and smaller signal distortion; and the cable can be installed at a time.
Description
Technical field
The present invention relates to cable, particularly relate to a kind of fire resistance frequency-changing cable peculiar to vessel.
Background technology
At present, along with the increase of Shipping demand, shipping industry has obtained large development；The development of shipping industry brings many development opportunities to equally cable for ship industry；Among these, the frequency-changing cable that other frequency conversion equipments such as boats and ships up-conversion motor use is owing to needing higher capacity of resisting disturbance, longer service life, therefore conventional cable is prevented fires at high temperature, shielding insulation performance, the aspects such as ageing-resistant, oil resistant still have certain defect, distorted signals is many, and shielding properties is not enough.
Summary of the invention
For meeting above-mentioned requirements, it is an object of the present invention to provide a kind of fire resistance frequency-changing cable peculiar to vessel.
The solution of the present invention is as follows: a kind of fire resistance frequency-changing cable peculiar to vessel; including master core conductor and earth lead; described master core conductor is closely extruded formed by two mutual stranded silver-plated copper conductor and a plastic-aluminum filler rod; described master core conductor and earth lead are wrapped with insulating protective layer, and described three master core conductors three piece earth leads equally distributed with outside it extrude into cable core；Described cable core center is provided with a control conductor, is disposed with inner liner, screen layer, armor, water blocking layer, restrictive coating and refractory protection outside described cable core.
As preferably, described inner liner is that two-sided synthetic mica tape is constituted.
As preferably, described armor forms for annealing copper wire or tinned copper wire braiding.
As preferably, described oversheath is made up of the wrinkle composite steel-plastic belt moisture-proof layer and black polyethylene sheath indulging bag overlap joint.
Beneficial effects of the present invention: relative to prior art, its current-carrying capacity of cable making same cross section when the made cable of the present invention normally works is bigger, reduce frequency-changing cable electromagnetic wave equipment to external world and the interference of system simultaneously, the dividing structure equally and can effectively reduce the impact of higher hamonic wave of three earth conductors, weaken frequency conversion motor noise, realize energy-conservation to a greater extent, improve efficiency, cable uses inner liner, screen layer, armor, water blocking layer, restrictive coating and refractory protection, which enhance waterproof, wear-resisting, moisture-proof, oil resistant, the performances such as fire-proof high-temperature resistant, can be-40～200 DEG C of uses, life-span is up to more than 10 years, and advantages of good shielding performance, distorted signals is little, can disposably install, the advantages such as stable equipment operation.

Wherein: 1, earth lead；2, insulating protective layer；3, silver-plated copper conductor；4, plastic-aluminum filler rod；5, control conductor；6, inner liner；7, screen layer；8, armor；9. water blocking layer；10, restrictive coating；11, refractory protection.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings；
As shown in Figure 1; a kind of fire resistance frequency-changing cable peculiar to vessel; including master core conductor and earth lead 1; described master core conductor is closely extruded formed by two mutual stranded silver-plated copper conductor 3 and a plastic-aluminum filler rod 4; described master core conductor and earth lead 1 are wrapped with insulating protective layer 2, and described three master core conductors three piece earth leads 1 equally distributed with outside it extrude into cable core；Described cable core center is provided with a control conductor 5, is disposed with inner liner 6, screen layer 7, armor 8, water blocking layer 9, restrictive coating 10 and refractory protection 11 outside described cable core.
Described inner liner 6 is that two-sided synthetic mica tape is constituted.
Described armor 8 forms for annealing copper wire or tinned copper wire braiding.
Described oversheath 10 is made up of wrinkle composite steel-plastic belt moisture-proof layer and the black polyethylene sheath of vertical bag overlap joint.
Although the detailed description of the invention to the present invention gives detailed description and explanation above; but it should be noted that; we can carry out various equivalence according to the conception of the present invention to above-mentioned embodiment and change and amendment; function produced by it still without departing from description contained spiritual time, all should be within protection scope of the present invention.
