Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] refer to figure 1 , The round aluminum conductor water-blocking cable 10 of the present invention adds three additional layers of structure to one end of the common core wire 11, so as to achieve the purpose of waterproofing and water-blocking. The three-layer structure is water-blocking yarn 12, single-sided insulating water-blocking tape 14, and semiconductive resistance water-binding tape 13.

[0019] Such as figure 1 As shown, the core wire 11 is covered by a multi-layer single-sided insulating water-blocking tape 14, and the water-blocking surface of the single-sided insulating water-blocking tape 14 faces the outside of the cable. Here, the purpose of the present invention can be achieved by using a single-sided insulating water-blocking tape, but the present invention is not limited to this, and double-sided in...

Abstract

The invention discloses a round aluminum conductor water resistance cable and a manufacture method of the round aluminum conductor water resistance cable. The cable structurally comprises a core wire, water resistance yarn, single-face insulating water resistance belts and a semiconducting water resistance lashing band. The core wire is wrapped by a plurality of layers of single-face insulating water resistance belts, and the water resistance yarn is arranged on the outer layer of the plurality of layers of single-face insulating water resistance belts. The semiconducting water resistance lashing band is strapped on the outmost layer of the water resistance yarn and the plurality of layers of single-face insulating water resistance belts, and the water resistance yarn, the single-face insulating water resistance belts and the plurality of layers of single-face insulating water resistance belts are jointly molded in extrusion mode to form an integrated multi-layer structure. By adopting the technical scheme, the round aluminum conductor water resistance cable can effectively prevent the cable from water seepage, enables conductors to have a water resistance function, and is simple in technology and convenient to operate.

Description

technical field [0001] The invention relates to a waterproof cable structure, in particular to a water-blocking cable with a round aluminum conductor. Background technique [0002] The safety of cables is a permanent topic in the cable industry. The safety of cables is mainly reflected in the following two points. One is the structure of the cable that is not easy to bend and break, and the other is the waterproof performance of the cable. [0003] At present, users have higher and higher requirements for the quality of high-voltage cables of 110kV and above. In addition to cables that must meet national standards and IEC standards, users have added many additional requirements, such as conductor water resistance. Once the cable is mechanically damaged by external forces, the conductor must be in all directions. Water blocking, to ensure that the cable restores power in the shortest possible time. [0004] However, the current common cables have greatly improved their bendi...
