Abstract
The utility model discloses an aluminum-alloy cable special for a frequency converter, and the cable mainly comprises a steel cord, aluminum-alloy cable cores, aluminum cable cores, an insulating shielding layer, a non-metal wrapping layer, a galvanized copper-tape armor layer, and a sheath. The interior of the insulating shielding layer is provided with three groups of aluminum-alloy cable cores and two groups of aluminum cable cores in an extruding and wrapping manner. Each aluminum-alloy cable core consists of an aluminum-alloy conductor and a shielding sheath. Each aluminum cable core consists of an aluminum conductor and an insulating layer. The exterior of the insulating shielding layer is wrapped by the non-metal wrapping layer which is wrapped by the galvanized copper-tape armor layer. The cable provided by the utility model can be widely used for the power transmission between frequency converters and motors in frequency-converting control transmission systems in steel industry, metallurgy industry, electric power industry, chemical industry, papermaking industry, and the like. The cable is strong in resistance to electromagnetic interferences, is strong in resistance to tearing and pulling, and is resistant to high temperature.
