Fluoroplastic anti-internal damage cable

Abstract

The invention belongs to the cable field and relates to a fluoroplastic anti-internal damage cable. The cable comprises a plurality of cable cores; each cable core comprises a conductor; the exteriorof each conductor is provided with a fluoroplastic insulating layer through extrusion; the fluoroplastic insulating layers are wrapped with a tin foil shielding layer; the tin foil shielding layer iswrapped with a metal armoring layer; the cross section of the metal armoring layer is of a square structure for facilitating blocking internal damage in all directions; the cross section of the tin foil shielding layer is of a net structure with high capacity to resist mechanical forces; the metal armoring layer is wrapped with a copper wire braided layer; the copper wire braid braided layer is wrapped with a water blocking tape layer; and the exterior of the water blocking tape layer is provided with a cross-linked polyethylene sheath through extrusion. According to the fluoroplastic anti-internal damage cable of the invention, the metal armoring layer and the tin foil shielding layer are combined with each other, and therefore, the interior of the cable can be effectively and stably protected from being damaged. The cable cores of the cable of the present invention are distributed regularly, so that the cable cores can be timely connected when being damaged in the future, and therefore, costs and losses can be reduced.

Description

technical field [0001] The invention relates to the field of cables, in particular to a fluoroplastic anti-internal damage cable. Background technique [0002] In the use of cables, the inner layer of the cable is often disordered due to the trampling of the construction personnel, and the cable cores are overlapped with each other, which is very easy to cause internal damage and cause the cable to be scrapped. Therefore, it is very important to maintain the internal stability of the cable. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a fluoroplastic anti-internal damage cable. [0004] A fluoroplastic anti-internal damage cable, including several cable cores, the cable cores include conductors, and the exterior of the conductors is extruded with a fluoroplastic insulating layer, and the exterior of the fluoroplastic insulating layer is wrapped with tin foil Shielding layer, the outer of the tin foil shielding lay...
