Abstract
The invention discloses an aluminum alloy cable special for a frequency converter. The aluminum alloy cable mainly comprises a steel wire rope, three groups of aluminum alloy cable cores, two groups of aluminum cable cores, an insulating shielding layer, a non-metal taped covering, a galvanized copper strip armor layer and a sheath. The aluminum alloy cable cores and the aluminum cable cores are wrapped in the insulating shielding layer in an extruded mode, wherein the aluminum alloy cable cores are composed of aluminum alloy conductors and shielding sheath layers, and the aluminum cable cores are composed of aluminum conductors and insulating layers. The insulating shielding layer is coated with a non-metal wrapping layer, and the non-metal wrapping layer is coated with the galvanized copper strip armor layer. The aluminum alloy cable can be widely applied to power transmission between frequency converters and motors of frequency conversion control and transmission systems in industries like steel, metallurgy, electric power, chemical industry and papermaking and has the advantages of being strong in anti-electromagnetic interference and tearing resistance and resistant to high temperature.
