Title:
COMPOSITE FIRE-RESISTANT CABLE
Document Type and Number:
WIPO Patent Application WO/2021/031329
Kind Code:
A1
Abstract:
The present utility model relates to the field of anchoring structural components, and in particular relates to a composite fire-resistant cable. The composite fire-resistant cable comprises a cable body, and further comprises a first fire-resistant layer wrapped on an outer surface of the cable body, and a sleeve disposed around the outside of the first fire-resistant layer, wherein a gap is provided between an inner surface of the sleeve and an outer surface of the first fire-resistant layer. A second fire-resistant layer is wrapped on an outer surface of the sleeve. The cable of the present utility model has a two-layer protection system serving fire-resistance and thermal insulation functions, and a thermal insulation technique of fireproofing cladding is used in between the two fire-resistant layers, thus significantly improving the high temperature resistance, and extending the fire resistance time of the cable.
