Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] figure 1 In the above, the exterior of the conductor 2 is wrapped with an inner layer insulation 3 made of cross-linked polyethylene insulation material and an outer layer insulation 4 of low-smoke halogen-free polyolefin insulation material. Each conductor 2 is placed in the filling body 6 , and the outer wall of the filling body 6 is wrapped with an inner wrapping overall shield 7 , an outer braided overall shield 8 , an inner sheath 9 and an outer sheath 10 . Every two-core conductor 2 is a group, and its exterior is wrapped with the inner layer wrapping sub-shield 1 and the outer braided sub-shield 5 in turn.

[0026] Among them, the inner wrapping overall shield 7 and the inner wrapping sub-shield 1 are made of aluminum-plastic composite tape, and the outer braided sub-shield 5 and the outer braided overall shield 8 are braided with copper ...

Abstract

The invention discloses a computer cable for a nuclear power station, which solves the problems of poor shielding performance and low wear-resistant degree of the computer cable for the nuclear power station in prior art and has the advantages of simple structure, convenient usage and effective enhancement of the ante-interference ability of the cable. The structure of the computer cable for the nuclear power station is that: the invention is provided with a plurality groups of conductors; outer walls of every group of conductors are covered with an insulating layer and are arranged in a backfill body; the outer wall of the backfill body is provided with a cable double-layer sheath and a heterogeneous cable double-layer shield; at the same time, every two cores of conductors forms one group, the outside of which is provided with a heterogeneous conductor double-layer shielding layer.

Description

technical field [0001] The invention relates to a cable, in particular to a computer cable for a nuclear power plant. Background technique [0002] At present, the cables used in nuclear power plants are mostly single-layer shielding and single-layer sheath due to cost considerations, which results in low anti-interference and wear resistance of the cables, especially for nuclear power plant computer cables. problems, and the existing single-layer shielding and single-layer sheathing structure can no longer meet the requirements. Contents of the invention [0003] The purpose of the present invention is to solve the problems of poor shielding ability and low wear resistance of current nuclear power plant computer cables, and to provide a nuclear power plant computer cable with the advantages of simple structure, convenient use, and effective improvement of cable anti-interference ability. . [0004] To achieve the above object, the present invention adopts the following ...
