Abstract
The invention relates to a movable medium-voltage silicone rubber special cable resistant to high and low temperature and interference. The cable comprises a plurality of flexible conductors, a semiconductive reinforcing wrapping tape, an inner shielding layer, a silicone rubber insulating layer, an outer shielding layer and a copper tape shielding layer are sequentially arranged outside each flexible conductor from inside to outside to form an insulating wire core, a PPD wrapping tape is extruded and wrapped by a plurality of insulating wire cores together to form a cable core, a woven shielding layer and a silicone rubber outer sheath are successively arranged outside the cable core from inside to outside, and a filler is arranged between each insulating wire core and the PPD wrapping tape. The movable medium-voltage silicone rubber special cable has the benefits that the cable has the characteristics of high and low temperature resistance, oil resistance, bending resistance, corrosion resistance, radiation resistance, high flexibility and the like, and can ensure the normal operation of a circuit under the conditions of laying in narrow space and at low temperature and high-intensity radiation; the service life of the cable is prolonged, and the range of application is expanded.
Description
Technical field
The present invention relates to a kind of special cable, particularly relate to a kind of anti-high and low-temp, anti-interference mobile with in press silicon rubber special cable.
Background technology
At present, midium voltage cable often uses Equations of The Second Kind compact conductor, and use XLPE as insulating barrier, its minimum bending radius can only reach 15 times of the outside diameter of cable, and product is not suitable for mobile laying, and can not meet the requirement of less bending radius; At present, the temperature resistant grade of conventional midium voltage cable concentrates on subzero more than 40 degree mostly, lays that temperature is minimum is not less than 0 degree, which also limits application; The midium voltage cable signal of telecommunication often can receive interference, and common cable structure is difficult to meet strongly disturbing service condition.
Summary of the invention
In order to overcome the above problems, the present invention provides that a kind of compact conformation, high-low temperature resistant, oil resistant are ageing-resistant, the anti-high and low-temp of long service life, anti-interference mobile with in press silicon rubber special cable.
Technical scheme of the present invention is: described cable comprises some flexible conductors, described flexible conductor sets gradually semiconductive outward from the inside to the outside and strengthens twining package tape, internal shield, silicone rubber insulation layer, outer shielding layer and copper strip shielding layer formation insulated wire cores, described some insulated wire cores jointly extrude PPD twining package tape and form cable core, described cable core sets gradually woven shield and silicon rubber oversheath outward from the inside to the outside, is provided with filling between described insulated wire cores and PPD twining package tape.
Described flexible conductor is consisted of bundle strand and multiple strand multiply soft copper conductor.
Described internal shield and outer shielding layer are silicon rubber screen.
Described woven shield is zinc-plated copper free wire woven shield.
Conductor of the present invention adopts the 5th class or the soft level conductor of the 6th class to make, thus solves the fundamental issue of cable softness; Insulating barrier adopts high tear silicon rubber insulation, is characterized in possessing the features such as high-low temperature resistant, oil resistant, ageing-resistant, anticorrosion, nonpoisonous and tasteless, flexibility strong, possesses superior electric property simultaneously; Shielding adopts zinc-plated braiding copper wire, possesses the effect of anti-oxidant, high shielding; Restrictive coating adopts the silicon rubber of high-low temperature resistant type height cracking resistance to make, and possesses the performances such as anti-high and low-temp, oil resistant, warp resistance, ageing-resistant, antifatigue.
The invention has the beneficial effects as follows: possess anti-high and low-temp, oil resistant, resist bending, corrosion-resistant, the feature such as radioresistance, high flexibility, can meet lay at narrow space, low temperature lay and high-level radiation condition under the normal operation of circuit, extend the useful life of cable and widened the scope of application.
