Abstract
The invention discloses a double-shielding and anti-interference power cable. The double-shielding and anti-interference power cable is composed of power wire cores, a shielding cable core, a copper strap lapped covering layer, a lapper covering strap layer and an outer sheath, wherein a silver-plated copper wire stranded conductor is sequentially wrapped in an insulating shielding layer, a lining layer, a conductor shielding layer and a silicon rubber insulating layer in an extruding mode from interior to exterior to form each power wire core; a silver-plated copper wire stranded conductor is sequentially wrapped in a copper wire woven lapped covering layer and a fluororubber insulating layer in an extruding mode from exterior to interior to form the shielding cable core; the two power wire cores and the shielding cable core are wrapped in a glass fiver woven layer in an extruding mode to form a cable core, the gap of the cable core is filled with a flame-retardant filling rope, and the copper strap lapped covering layer, the lapped covering strap layer and the outer sheath are arranged outside the cable core; forming flame-retardant filling bars are arranged between the copper strap lapped covering layer and the lapped covering strap layer; a copper-clad steel armored layer is arranged between the lapped covering strap layer and the outer sheath. The double-shielding and anti-interference power cable is simple in structural design, stable in performance, capable of meeting the performance requirement of a variable frequency power cable, good in shielding performance and high in structural strength.
Description
Technical field
The present invention relates to cable, relate in particular to the anti-interference power cable of a kind of double shield.
Background technology
Along with recent two decades carrys out the progress of power electronic technology, frequency conversion system has been widely used in various industrial occasions, find in actual use, in general electrical system, be not considered to the cable of weak link, but run at frequency conversion system the problem seldom occurring in the ordinary course of things, as electric shield weak effect, electromagnetic interference is serious etc., makes frequency converter cisco unity malfunction.Therefore, although variable-frequency control technique has obtained using widely in industrial aspect such as oil, metallurgy, generating, railway, mines, but answer in contrast for connecting the service cable of variable-frequency motor and variable frequency power supply, in actual installation, be but to adopt general common power cable, impact has restricted the normal use of frequency converter.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide the anti-interference power cable of a kind of double shield.
The solution of the present invention is as follows: the anti-interference power cable of a kind of double shield, it is made up of power core, shielding core, copper strips lapping layer, wrapped belt and oversheath, and described power core is to be coated on from inside to outside on silver-gilt copper wire stranded conductor and to be formed by insulation screen, pad underlayer, conductor shield and silicone rubber insulation layer; Described shielding core is to be formed on being coated on outside to inside silver-gilt copper wire stranded conductor by proof copper-wire braided lapping layer and fluorubber insulating barrier; Described two power cores are extruded into cable core with a shielding core by fiberglass braided layer; Described cable core gap-fill has fire-retardant gasket for packing, and cable core is provided with copper strips lapping layer, wrapped belt and oversheath outward; Between described copper strips lapping layer and wrapped belt, be provided with moulding flame retardant filler strip; Between described wrapped belt and oversheath, be provided with copper covered steel armour.
In described pad underlayer, be provided with a ground core.
Described oversheath adopts flame-proof polyvinyl chloride material.
Beneficial effect of the present invention: structural design of the present invention is simple, stable performance, can meet the performance requirement of frequency-conversion power cable, advantages of good shielding performance, structural strength is high.
