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

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, this embodiment includes a cable core stranded by a plurality of insulated wire cores. The insulated wire core is composed of a water-blocking conductor 1 and an anti-water tree insulating layer 2 extruded outside the water-blocking conductor 1. The water-blocking conductor 1. The water-blocking aluminum alloy conductor with stranded wire structure can better replace copper conductor cables, and solve the problems of easy oxidation and poor creep resistance of electrical pure aluminum conductors. Moreover, the material cost is low and the economic performance is excellent. At the same time, the water-blocking conductor 1 also adopts the wire stranding process and the longitudinal wrapping structure of the semi-conductive resistance water belt, which has a high conductor compression coefficient and a good w...

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...
