Control cable for nuclear power station

Abstract

The invention discloses a control cable for a nuclear power station. The control cable comprises a round reinforcement insulation tube, wherein a Y-shaped insulation partition plate is arranged in the reinforcement insulation tube, eight insulation partition plates are uniformly arranged on an outer wall of the insulation reinforcement tube in a radial way, three main wire cores are arranged between the Y-shaped insulation partition plate and an inner wall of the insulation reinforcement tube, and each main wire core comprises a main conductor and a trifluoropropyl silicone rubber insulation layer and a semiconduction shielding layer which sequentially wrap the main conductor. In the control cable, the Y-shaped insulation partition plate is arranged in the reinforcement insulation tube, the eight insulation partition plates are uniformly arranged on the outer wall of the insulation reinforcement tube in a radial way, the control cable has the advantages of simple structure, good insulation effect, good extrusion-resistant and tensile effect, low cost, high shielding anti-jamming ability, high weather resistance and multi-layer insulation and shielding, and is convenient to use and stable and reliable to work, a semiconduction expansion buffer layer is high in buffer shock-resistant effect.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a control cable for nuclear power plants. Background technique [0002] At present, most of the control cables used in nuclear power plants are cables with poor anti-interference ability, insulation and shielding ability, and poor weather resistance. They have short service life, frequent failures, high replacement costs, and great risks to the safe and stable operation of nuclear power plants. Contents of the invention [0003] The object of the present invention is to provide a control cable for nuclear power plants in order to remedy the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A control cable for nuclear power plants, including a circular reinforced insulating tube, a Y-shaped insulating partition is arranged inside the reinforced insulating tube, and 8 insulating partitions are evenly arranged ...
