Problems solved by technology

The way of water intrusion is mainly to invade the cable from the cable sheath and the end of the cable, causing oxidation and corrosion of the conductor, thereby affecting the electrical performance of the cable, and even abnormal disconnection accidents; , the insulation layer will produce "water branches", which will accelerate the electrical aging of the cable, cause cable breakdown accidents, and reduce the service life of the cable

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] Such as figure 1 A combination of split conductors with built-in optical fibers in the center of a water-blocking type shown includes a central support strand 1, and the conductor structure is composed of several corrugated conductor strands 2 and a central support strand; the several corrugated conductor strands A corrugated water-blocking layer 3 is arranged outside the shaped conductor strand, and the several corrugated-shaped water-blocking layers surround the central support strand with the central support strand as the center; The hose 4; the central support strand is formed by twisting a plurality of wire bundles 5; at least one of the wire bundles has an optical fiber unit 6 directly attached to the center.

[0021] Such as figure 2 As shown, there are two optical fiber units 6 in the silk bundle 5 , and the gaps between the optical fiber units 6 are fille...

Abstract

The invention discloses a water-blocking combined segmented conductor with a built-in central optical fiber. The water-blocking combined segmented conductor comprises a central support strand block. The conductor structure is formed by assembling a plurality of corrugated conductor strand blocks and the central support strand block. Corrugated water-blocking layers are arranged out of the plurality of corrugated conductor strand blocks. The corrugated water-blocking layers surround the central support strand block by taking the central support strand block as a center. A water-blocking tape is arranged out of the plurality of corrugated water-blocking layers. The central support strand block is formed by twisting a plurality of silk thread bundles. At least one center of the silk thread bundles is directly towed with optical fiber units. According to the water-blocking combined segmented conductor, the corrugated water-blocking layers are arranged out of the corrugated conductor strand blocks, the water-blocking tape is arranged out of the corrugated water-blocking layers, so the integrated conductor is protected by the water-blocking layer, the conductor has a high water-blocking function, the conductor is not oxidized and corroded due to water immersion, the electric performance of the cable is prevented from being influenced and an abnormal cable breakage event is prevented from occurring.

Description

technical field [0001] The invention relates to the field of cable conductors, in particular to a water-blocking composite split conductor with built-in optical fibers in the center. Background technique [0002] With the rapid growth of China's economy and the further acceleration of industrialization and urbanization, the requirements for the construction of infrastructure such as urban power grids are increasing. Cities in developed regions and provincial capitals have required the use of underground power cables to transmit electric energy in urban centers. At the same time, electricity is the premise and foundation of the development of the national economy. With the rapid development of the national economy, the demand for electricity has increased sharply, the capacity of the grid has increased sharply, and the power of motors has increased. ) transmission direction development. In order to increase the carrying capacity of the cable, the method of increasing the cro...
