Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] exist figure 1 As shown in , the fire-resistant and flame-retardant wire and cable threading anti-damage technology of the present invention includes the processes of wire drawing, annealing, stranding, insulation extrusion, and finished product packaging in sequence, and silicone oil is added in the insulation extrusion process.

[0013] Silicone oil is added in the production process to lubricate the sheath layer of fire-resistant and flame-retardant wire and cable, reduce the friction and adhesion of fire-resistant and flame-retardant wire and cable when passing through the pipe, and achieve the purpose of protecting the sheath layer from being damaged during the pipe-threading process. The silicone oil contains the following substances by weight percentage, EVA: 36%; PE: 3%; aluminum hydroxide: 55%; organic silicone: 2%, antioxidant 1010: 0.5...

Abstract

The invention relates to a damage-prevention threading technology for flame-retardant type wires and cables, which sequentially comprises the steps of drawing, annealing, stranding, insulated extrusion molding and finished product packaging. Silicone oil is added in the insulated extrusion molding process. The damage-prevention threading technology for the flame-retardant type wires and cables has the advantages of overcoming the defect of skin damage caused by increased wire frictional force of a wire body in the perforating and threading processed of the traditional flame-retardant type wires and cables, reducing the potential safety hazards caused in the perforating and threading process and solving the problem just by adding the silicone oil in the production process.

Description

technical field [0001] The invention relates to a cable, in particular to a fire-resistant and flame-retardant wire and cable threading anti-damage technology. Background technique [0002] At present, with the development of society, the fire protection of high-rise buildings is getting higher and higher. More and more construction projects have put forward new requirements for the combustion performance of the wires and cables used. Various types of flame-retardant wires and cables appear in the threading During the process, due to problems such as cross-linking and irradiation of the outer skin, it is not as easy as ordinary PVC wires to be threaded through the pipe, so the fire-resistant and flame-retardant wires and cables appear in the process of threading the pipe. Hidden danger. Contents of the invention [0003] In order to overcome the existing fire-resistant and flame-retardant wire and cable threading process due to the increase in wire body friction caused by...
