Abstract
The utility model relates to an anticorrosive energy-saving environment-friendly variable frequency cable for a ship, and belongs to the technical field of cables. The cable comprises three main wire cores, three neutral wire cores and a cable core consisting of a group of anisotropic filler twisted materials. A flexible copper strip lapped screen layer, a tinned copper wire woven armor layer and an extruded halogen-free low-smoke flame-retardant oil-proof sheath layer are sequentially arranged outside the cable core from inside to outside. The cable has the characteristics of corrosion resistance, high signal transmission capability, high anti-electromagnetic interference performance, nontoxicity and environment friendliness, is applied to a variable frequency motor of the ship, and also can be widely applied to offshore oil platform equipment, port running equipment and field mobile equipment.
Description
Technical field
The utility model belongs to the cable technology field, particularly a kind of boats and ships frequency-changing cable technical field of structures.
Background technology
Energy-saving of motor system is one of ten large emphasis energy conservation projects of National Development and Reform Committee's startup.The national development planning requirement, currently should promote frequency converter power-saving technology namely: the universal machine systems such as motor, blower fan, water pump, compressor adopt the variable-frequency speed-adjusting energy-saving measure, and industrial machinery adopts alternating current motor frequency conversion technique speed adjusting technique.Variable-frequency control technique is a kind of novel electric power drive speed-adjusting technology; has good speed adjusting performance at tuning range, static accuracy, dynamic quality, system effectiveness, perfect defencive function, the easy aspects such as automatic control and process control of realizing; the significant role such as significant saves energy and protection of the environment are arranged, become one of breach of technological updating of enterprises and product renewal.
At present, the many products by beautiful, day, Europe manufacturer of the market share of variable-frequency speed-adjusting energy-saving motor cable are captured.Domestic production producer is few in number, accelerates the production domesticization of product, is the demand in market, also is the demand of national economy.Special in the shipbuilding industry of China, the demand of variable-frequency motor peculiar to vessel is increasing, and to the marine variable-frequency cable more particular requirement of having deducted a percentage.
Summary of the invention
The utility model purpose is for severe rugged environments such as boats and ships operating characteristic and marine qarosols, proposes a kind of Novel corrosion-proof energy-saving environmental protection type ship frequency-changing cable.
The utility model is by three master cores, three neutral cores and one group of cable core that the stranded material of opposite sex inserts consists of, described master core and neutral core are spaced, described different in nature inserts is arranged between the gap of master core and neutral core, and cable core is outer by extremely setting gradually soft copper band lapped shielding layer, tinned copper wire braiding armour outward and extruding LSOH anti-flaming oil-resisting type restrictive coating; Every described master core is by the stranded conductor that forms of multiply tinned copper wire, and the flame retardant coating, LSOH anti-flaming environmental protection insulating barrier and the tinned copper wire phase-splitting screen that are successively set on outside the conductor form; Every described neutral core is that the stranded naked tinned copper wire of multiply forms.
The stranded material of different in nature inserts described in the utility model is comprised of the stranded steel wire strand conductor LSOH anti-flaming Insulation Material outer with being extruded in stranded steel wire strand conductor.
The special severe rugged environments such as the utility model is strong for marine salt fog corrosive properly, ultraviolet radiation is strong, the temperature difference is large in conjunction with the marine electrical motors operating characteristic, provide that a kind of antijamming capability is strong, corrosion-resistant, Halogen, low cigarette, nontoxic new product.This long product lifecycle, bending property be superior, be easy to install, and can extensively use installing and using of boats and ships, offshore oil platform exploration, harbour driving equipment, field movable equipment.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
The utility model is by three master cores 1, three neutral cores 2 and one group of cable core that the stranded material 3 of opposite sex inserts consists of, and master core 1 and neutral core 2 are spaced, and different in nature inserts 3 is arranged between the gap of master core 1 and neutral core 2.Cable core is outer by extremely setting gradually soft copper band lapped shielding layer 4, tinned copper wire braiding armour 5 outward and extruding LSOH anti-flaming oil-resisting type restrictive coating 6.
Every master core 1 is by the stranded conductor that forms 11 of multiply tinned copper wire, and the flame retardant coating 12, LSOH anti-flaming environmental protection insulating barrier 13 and the tinned copper wire phase-splitting screens 14 that are successively set on outside the conductor 11 form.
Every neutral core 2 is that the stranded naked tinned copper wire of multiply forms.
The stranded material 3 of opposite sex inserts is comprised of stranded steel wire strand conductor 31 and the LSOH anti-flaming Insulation Material 32 that are extruded in outside the stranded steel wire strand conductor 31.
