Control cable for anti-radiation ship

Abstract

The invention discloses a control cable for an anti-radiation ship. The control cable comprises a cable core; the cable core comprises a framework; the framework comprises a main framework with a regular triangular cross section and three auxiliary frameworks with regular triangular cross sections; grooves are formed in the middle parts of the three surfaces of the main framework in the axial direction respectively, and one auxiliary framework is arranged in each groove; the two tangent planes of each groove are clamped on the center lines of the two surfaces of the corresponding auxiliary framework respectively; the main framework and the three auxiliary frameworks are of an integrated structure; a control wire core is arranged in each of the three corners of the main framework and the three auxiliary frameworks separately; and the outer side of the cable core is sequentially coated with a cross-linked polyolefin inner sheath, a tinned copper strip braided main shielding layer and a cross-linked polyolefin outer sheath from inside to outside. The control cable is provided with the framework, wherein the framework comprises the main framework with the regular triangular cross section and the three auxiliary frameworks with regular triangular cross sections; and by virtue of the stability of the triangle, a high protection effect is achieved on the control wire core; and meanwhile, the anti-compression and tensile properties of the cable can be improved.

Description

technical field

[0001] The invention relates to the technical field of cables, in particular to a radiation-proof marine control cable. Background technique

[0002] The wires and cables used in the high-temperature environment on board have poor anti-interference ability, which may easily cause transmission signal disorder, and even cause casualties or property losses. The inner conductor of the traditional marine cable is a copper conductor, and the sheath is a single-layer PVC sheath. Most of the cables for ships and marine engineering now require the cables to be low-smoke, halogen-free, environmentally friendly, corrosion-resistant, insect-resistant, and anti-corrosion. Water characteristics, it is obvious that traditional marine control cables can no longer meet the requirements of modern ships. Contents of the invention

[0003] The object of the present invention is to provide a radiation-proof marine control cable in order to remedy the defects of the prior art. ...

Examples

Embodiment Construction

[0023] Such as figure 1 As shown, a radiation-proof marine control cable includes a cable core, and the cable core includes a skeleton, and the skeleton includes a main skeleton 1 with a regular triangle cross section and three sub skeletons 2 with a regular triangle cross section. The middle parts of the three faces of the main frame 1 are grooved in the axial direction, and a sub-frame 2 is arranged in each groove, and the two cut surfaces of the groove are respectively clamped on the centerlines of the two faces of the corresponding sub-frame 2 , the main skeleton 1 and the three sub-skeletons 2 are integrated structures; the three corners of the main skeleton 1 and the three sub-skeletons 2 are respectively provided with a control wire core, and the control wire core includes two Conductors 3, each conductor 3 is respectively coated with a cross-linked polyethylene insulating layer 4 and twisted, and the two conductors 3 after twisting are coated with a polyester film wrap...
