Abstract

The utility model discloses a double-shielded anti-interference power cable, which is composed of power wire cores, a shielded wire core, a copper tape wrapping layer, a wrapping tape layer and an outer sheath, wherein the power wire core is formed by coating an insulating shielded layer, a lining layer, a conductor shielding layer and a silicon rubber insulating layer on a silver-plated copper wire stranded conductor from the inside out; the shielded wire core is formed by coating a copper wire braided wrapping layer and a fluororubber insulating layer on the silver-plated copper wire stranded conductor from the outside in; the two power wire cores and the shielded wire core are extruded by a glass fiber braiding layer into a cable core; gaps of the cable core are filled with flame retardant filling ropes, and the cable core is externally provided with the copper tape wrapping layer, the wrapping tape layer and the outer sheath; the copper tape wrapping layer and the wrapping tape layer are provided with a molding flame retardant filling strip therebetween; and the wrapping tape layer and the outer sheath are provided with a copper-clad steel armor layer. The double-shielded anti-interference power cable is simple in structural design, stable in performance, capable of meeting performance requirements of a variable frequency power cable, and good in shielding performance and high in structural strength.

Description

The anti-interference power cable of a kind of double shield
Technical field
The utility model relates to cable, relates 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.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide the anti-interference power cable of a kind of double shield.
Scheme of the present utility model 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; 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.
The beneficial effects of the utility model: the utility model structural design is simple, stable performance, can meet the performance requirement of frequency-conversion power cable, advantages of good shielding performance, structural strength is high.
