Abstract

The invention discloses a flexible refractory cable with ceramic elastomer sheath, including protective jackets, the outer part of the protective jacket is provided with a polyurethane elastic extrusion cladding layer, aramid yarn is arranged on the inner wall of the polyurethane elastic extrusion cladding, one side of the aramid yarn inner wall is provided with a ceramic silicon rubber extrusioncladding layer, A loose sleeve is arranged inside the protective sleeve, a PVC insulating coating is arranged outside the loose sleeve, a metal woven net is arranged on the inner wall of the PVC insulating coating, a glass fiber protective layer is arranged on one side of the inner wall of the metal woven net, and cable wires are arranged inside the loose sleeve. The invention solves the problemsof poor abrasion resistance, poor waterproofing and fireproofing performance, insufficient softness, low service life and the like of the existing flexible refractory cable.

Description

technical field [0001] The invention relates to the technical field of special wires and cables, in particular to a flexible fire-resistant cable with a ceramic elastomer sheath. Background technique [0002] In some mobile operation applications, such as mining engineering and tunnel engineering, flexible fire-resistant cables are receiving more and more attention. Flexible fire-resistant cables require both fire-resistant properties and must have the bending resistance, twist resistance, and pressure resistance of traditional rubber cables. The characteristics of movable laying such as collision resistance require it to make breakthroughs in structure, material and manufacturing process. Most of the traditional flexible fire-resistant cables are based on rubber-sheathed cables, adding a layer between the conductor and the insulating layer. Mica is wrapped around the cladding, and the fire resistance is improved to a certain extent, but the flexibility of the cable is great...
