Abstract
The utility model discloses an armored metallic shielding variable-frequency power cable equipped with an inner steel tape. The armored metallic shielding variable-frequency power cable comprises main conductors and neutral conductors. The surfaces of main conductors and the surfaces of the neutral conductors are successively wrapped in XLPE insulating layers, asbestos filling layers, and metallic shielding layers. The three main conductors are arranged centrally symmetrically. The neutral conductors are placed between every two main conductors. The main conductors and the neutral conductors are twisted in a compound manner to form a cable core. The outer side of the cable core is successively wrapped in a cabling wrapping tape, an inner sheath, a copper wire shielding layer, a copper tape shielding layer, an isolating sleeve, a steel tape armoring layer, and a flame-retardant polyvinyl chloride outer sheath. The armored metallic shielding variable-frequency power cable uses a crosslinked polyethylene insulating layer and applies the asbestos filling layers, the isolating sleeve, and the steel tape armoring layer so as to achieve characteristics of a good insulating and shielding effect, low production cost, and a good isolating effect.
Description
Technical field
