Single-core middle-voltage radial water-blocking cable

Abstract

The invention discloses a single-core middle-voltage radial water-blocking cable in the cable field, which comprises a water-blocking conductor. The periphery of the conductor is wrapped with a conductor shielding layer; the periphery of the conductor shielding layer is extruded with an XLPE insulated layer; the periphery of the XLPE insulated layer is wrapped with an insulated shielding layer; the periphery of the insulated shielding layer is wrapped with an inner semi-conductive water-blocking belt; the periphery of the inner semi-conductive water-blocking belt is wrapped with a metal shielding layer; the periphery of the metal shielding layer is wrapped with an outer semi-conductive water-blocking belt; the periphery of the outer semi-conductive water-blocking belt is vertically wrapped with an aluminum-plastic composite tape; and the periphery of the vertically-wrapped aluminum-plastic composite tape is extruded with an outer sheath. The single-core middle-voltage radial water-blocking cable has good water-blocking performance, and can be used in submarine data signal transmission.

Description

technical field [0001] The invention relates to a cable, in particular to a waterproof cable. Background technique [0002] The rapid development of power-related industries has led to a substantial increase in the demand for long-distance communication cables, but the environment for laying long-distance communication cables is complex. Whether it is laid in soil or water or erected in the air, there is sufficient moisture in the surrounding environment. Moisture infiltration into the cable after long-term use will greatly increase the communication loss of the cable, reduce the efficiency of the cable, and even cause problems such as communication failures. In order to improve the waterproof performance of the cable, it is necessary to add the necessary waterproof treatment to the structural design of the cable. measure. Contents of the invention [0003] The purpose of the present invention is to provide a single-core medium-voltage radial water-blocking cable, which i...
