Abstract
The invention discloses a waterproof rubber jacketed flexible cable special for a water fountain. The waterproof rubber jacketed flexible cable comprises a cable core formed by twisting a plurality of cores, a water-blocking filled layer filled among the cores and outside the cable core, and a water-blocking reinforced layer and a waterproof outer sheath which are sequentially extruded outside the cable core, wherein the core consists of a central flexible copper conductor, an isolation strip wrapped outside the flexible copper conductor and an insulating layer extruded outside the isolation strip. The waterproof rubber jacketed flexible cable is mainly applied to underwater power transmission of 750V and below and suitable for complex underwater environments, has high waterproofness, high bending properties and relatively stronger tensile strength, and can resist acid and alkali corrosion, prevent biting and bear mechanical impact.
Description
?
Technical field
The present invention relates to a kind of cable, specifically is a kind of water scenery fountain special-purpose water-proof rubber sleeve flexible cable.
Background technology
The common JHS type water-proof cable of the general employing of existing water scenery fountain private cable, such cable has water-proof function, is suitable for electric energy transmitting usefulness under water.Its structure is: extrude one deck insulation and form core outside conductor, some cores twine and form cable core, and the outer wrapped waterstop of cable core extrudes oversheath again.Though this JHS type water-proof cable has water-proof function; but consider cable immersion for a long time under bigger hydraulic pressure; and through regular meeting run into as animal bite, uncertain environmental factor such as acid and alkali corrosion, mechanical collision and influence normal use; make cable can't keep good electrical insulation properties and bending property; and regular move certainly will make cable be worn, thereby influence the fail safe and the useful life of cable use.So how to improve the performance of cable, particularly waterproof, anticorrosion, anti-performance such as bite is the primary at present problem that solves of such cable.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can effectively solve as animal bite, the water-proof cable of uncertain potential risk such as acid and alkali corrosion, mechanical collision.
A kind of water scenery fountain special-purpose water-proof rubber sleeve flexible cable of the present invention, it comprises by the stranded cable core that forms of some cores, fills the packed layer that blocks water between each core and outside the cable core, extrudes block water reinforced layer and waterproof oversheath outside cable core successively.
Described core is by the soft copper conductor of centre, is coated on the outer isolation strip of soft copper conductor and is extruded in the insulating barrier composition isolation strip outside.
The present invention mainly is applicable to 750V and following electric energy transmitting usefulness under water, has favorable waterproof property and bending property, and the environment that is fit to underwater complex uses, energy acid-alkali-corrosive-resisting, anti-biting, and have stronger tensile strength, can stand mechanical collision.
Description of drawings
Fig. 1 is a generalized section of the present invention.
Embodiment
Structure of the present invention adopts the 5th kind of soft copper conductor 1 of regulation among standard GB/T3956-2008 " conductor of cable ", wrapped isolation strip 2 outside soft copper conductor 1 as shown in Figure 1 on its conductor structure; Extruded insulation layer 3 outside the isolation strip.The insulating material of this insulating barrier 3 adopts IE4 type Insulation Material; The packed layer 4 that blocks water is adopted in the cable core gap during stranding, blocks water to fill to adopt the intumescent material water-proof material; The reinforced layer 5, waterproof oversheath 6 that block water adopts SE3 rubbers material to extrude.Effects such as waterproof oversheath, the reinforced layer and block water and fill the water resistance improved cable of blocking water, this structure also played and anti-ly bitten, corrosion-resistant, wear-resistant.
The present invention has substituted the single sheath structure of traditional cable, be to carry out stranding after the rubber insulation core machines, between cable core, add fillings that block water, and then wrapped polyester belt or nonwoven fabrics be wrapped in the outer formation of the cable core reinforced layer that blocks water, closely extrude rubber waterproof oversheath at last.
Preparation technology of the present invention:
What 1, conductor adopted is the 5th class conductor that meets among standard GB/T3956-2008, improves the crooking ability of cable;
2, wrapped one deck isolation strip on conductor, isolation strip are polyester belt or nonwoven fabrics or PP band;
3, extrude IE4 type insulation rubber outside the isolation strip as insulating barrier, form core.
4, some cores twine stranded formation cable core, and the filling that blocks water is set between cable core, guarantee that the waterproof of cable conductor and electric property are stable;
5, extrude SE3 type rubber block water reinforced layer and waterproof oversheath, when outer jacket breakage occurred water intrusion is arranged, the reinforced layer that blocks water can further prevent the excessive intrusion of moisture, guarantees the safe in utilization and useful life of cable.
Above-mentioned these execution modes only are used to illustrate the present invention, but do not limit the scope of the invention, and after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
