Novel energy-saving water-blocking cable

Abstract

The invention relates to a novel energy-saving water-blocking cable. The novel energy-saving water-blocking cable comprises a cable core formed by twisting a plurality of insulated wire cores, wherein each insulated wire core consists of a water-blocking conductor and a water-tree-resistant insulating layer extruded outside the corresponding water-blocking conductor; a water-blocking wrapping belt, a metal sheath water-blocking layer and a composite water-blocking sheath layer wraps the outside of the cable core in sequence; and the water-blocking wrapping belt is filled with water-blocking filling yarns. The novel energy-saving water-blocking cable is compact and reasonable in structure and convenient to manufacture, and is good in energy-saving effect, high in water-blocking performance, long in service life and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a novel energy-saving water-blocking cable. Background technique [0002] With the deepening of the research and understanding of insulation water absorption and water tree, people are more and more aware of the importance of waterproof performance for medium and high voltage power cables. At present, more and more users and various regional occasions have put forward waterproof requirements for cables. Therefore, water-blocking cables of various structures have emerged as the times require. [0003] At present, most of the electrical conductive materials used for power transmission are made of copper, but due to the shortage of domestic copper resources, about 70% of the copper materials need to be imported, and with the rising international copper price, the investment cost of conductive materials is increasing. The higher the value, the greater the consumption of...

Problems solved by technology

[0007] In addition, the traditional water-blocking cables generally only use water-blocking filling and water-blocking tape to achieve the purpose of water-blocking, but if this water-blocking cable is soaked in water for a long time, it will not achieve a good water-blocking effect. Moisture will enter in a short time and a breakdown short circuit will occur
