Abstract
The invention discloses a corrosion resistant frequency converter cable which comprises three main wire core elements and three ground wire core elements. Corrosion resistant packing layers are arranged outside the main wire core elements and the ground wire core elements and in the clearance between the main wire core elements and the ground wire core elements, and an inner shielding layer, a waterproof taped layer, an outer shielding layer and a corrosion resistant outer protective sleeve layer are arranged outside the corrosion resistant packing layers in sequence. Through the adoption of the mode, the corrosion resistant frequency converter cable has good corrosion resistant performance, is suitable for being used in severe environment, and further has good anti-disturbance performance.
Description
Technical field
The present invention relates to the cable technology field, particularly relate to a kind of corrosion-resistant converter cable.
