Embodiment Construction

[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] like figure 1 A radiation-resistant composite shielded nuclear power double-core control cable is shown, which is composed of a main conductor 1 and a secondary conductor 2. The cross-sectional diameter of the main conductor 1 is larger than the cross-sectional diameter of the secondary conductor 2. The insulating layer 3, the secondary conductor 2 is covered with a secondary composite insulating layer 4, and the main composite insulating layer 3 and the secondary composite insulating layer 4 are provided with an isolation layer 5, and the isolation layer 5 is coated with tinned copper wire and aluminum Composite shielding layer 6 made of braided plast...

Abstract

The invention relates to a radiation-resistant composite shielded nuclear power twin-core control cable which comprises a main conductor and an auxiliary conductor. A main composite insulating layer is coated on the outside of the main conductor, an auxiliary composite insulating layer is coated on the outside of the auxiliary conductor, an isolation layer is arranged on the outsides of the main composite insulating layer and the auxiliary insulating layer, a composite shielding layer is coated on the outside of the isolation layer, a sheath layer is coated on the outside of the composite shielding layer, and a protective layer is coated on the sheath layer. The radiation-resistant composite shielded nuclear power twin-core control cable has the advantages that the radiation-resistant composite shielded nuclear power twin-core control cable is provided with the composite shielding layer, so that high external electromagnetic interference can be effectively shielded and cannot affect the cable, normal usage of the cable can be guaranteed, and the stability of equipment can be improved.

Description

technical field [0001] The invention relates to the field of nuclear power cables, in particular to a radiation-resistant composite shielding nuclear power double-core control cable. Background technique [0002] The operating environment of nuclear power plants requires cables for nuclear power plants to have high electrical properties, high flame retardancy and radiation resistance. Cable products for nuclear power plants are divided into power cables for nuclear power plants, control cables for nuclear power plants, instrumentation and measurement cables for nuclear power plants, and compensation cables for nuclear power plants; they are divided into K1 cables, K2 cables, and K3 cables according to the installation area. K1 and K3 cables belong to 1E cables for nuclear power plants. [0003] The shielding layer of the currently used cables is a single structure, and its shielding performance is poor. For some strong interference sources, it cannot be effectively blocked ...
