Title:
ULTRA-HIGH FREQUENCY DIGITAL COMMUNICATION CABLE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/140129
Kind Code:
A1
Abstract:
An ultra-high frequency digital communication cable, comprising a cable core, a total shielding layer (6), an outer protection layer (7) and branch shielding layers (4) on twisted pair wire groups (3), wherein overlapping sides of the branch shielding layers (4) are clamped between two adjacent insulated single wires to form a branch shielding overlapping wire (8); the branch shielding overlapping wires (8) corresponding to two adjacent pairs of twisted pair wire groups (3) are arranged in a staggered manner; and the length for overlapping, outward-stretching sides of the branch shielding layers (4) to extend outwards from the branch shielding overlapping wires (8) is L1, L1 being 10%-15% of the width of a clad foil band of the branch shielding layers (4). The preparation method comprises the following steps: (1), drawing a copper conductor (1); (2), extruding an insulation layer; (3), twisting twisted pair wire groups (3); (4), cladding branch shielding layers (4); (5), twisting same into a cable; (6), weaving a total shielding layer (6); and (7), extruding an outer protection layer (7) into a finished cable. The communication cable not only has a good shielding effect and can effectively prevent intrusion and leakage of an electromagnetic wave, but also has a firm cable structure and stable transmission performance, and is particularly applicable to transmitting an ultra-high frequency band digital signal.
