Abstract

The utility model relates to a mobile medium-voltage silicone rubber special cable resistant to high and low temperature and interference. The cable comprises a plurality of flexible conductors each of which is successively wrapped with a semiconductive reinforcing wrapping tape, an inner shielding layer, a silicone rubber insulating layer, an outer shielding layer, and a copper tape shielding layer from inside to outside so as to form an insulating wire core. A PPD wrapping tape is coextruded on a plurality of insulating wire cores so as to form a cable core. The cable core is successively wrapped with a woven shielding layer and a silicone rubber outer sheath from inside to outside. A filling layer is arranged between the insulating wire cores and the PPD wrapping tape. The mobile medium-voltage silicone rubber special cable has beneficial effects of high and low temperature resistance, oil resistance, bending resistance, corrosion resistance, radiation resistance, and high flexibility, can be laid in narrow space and at low temperature, and satisfies the normal operation of a circuit under a condition of high-intensity radiation. In addition, the cable has a prolonged service life and a widened use range.

Description

Anti-high and low-temp, anti-interference mobile with in press silicon rubber special cable

Technical field

The utility model relates to a kind of special cable, relate in particular 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 is often used Equations of The Second Kind compact conductor, uses XLPE as insulating barrier, and 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 minimum 0 degree that is not less than of temperature, and this has also limited application; The midium voltage cable signal of telecommunication often can be received interference, and common cable structure is difficult to meet strongly disturbing service condition.

Utility model content

The utility model provides in order to overcome the above problems 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.

The technical solution of the utility model is: described cable comprises some flexible conductors, described flexible conductor sets gradually from the inside to the outside semiconductive outward 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, between described insulated wire cores and PPD twining package tape, is provided with filling.

Described flexible conductor crosses bundle strand by multiply soft copper conductor dbus and multiple strand forms.

Described internal shield and outer shielding layer are silicon rubber screen.

Described woven shield is zinc-plated copper free wire woven shield.

The utility model conductor adopts the 5th class or the soft level of the 6th class conductor to make, thereby has solved the fundamental issue of cable softness; Insulating barrier adopts high tear-proof silicon rubber insulation, is characterized in possessing high-low temperature resistant, the feature such as oil resistant, ageing-resistant, anticorrosion, nonpoisonous and tasteless, flexibility is strong, possesses superior electric property simultaneously; Shielding adopts zinc-plated braiding copper wire, possesses effect anti-oxidant, high shielding; Restrictive coating adopts the silicon rubber of high-low temperature resistant type high cracking resistance to make, and possesses the performances such as anti-high and low-temp, oil resistant, warp resistance, ageing-resistant, antifatigue.

The beneficial effects of the utility model are: possess the features such as anti-high and low-temp, oil resistant, resistance to bending, corrosion-resistant, radioresistance, high flexibility, can meet at narrow space lay, low temperature lay and the condition of high-level radiation under the normal operation of circuit, extended the useful life of cable and widened the scope of application.
