Embodiment Construction

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like figure 1 Shown: a wiring wire with a flame-retardant protective outer layer, comprising: a conductor 1, an insulating layer 2 wrapped on the outside of the conductor 1 and surrounded by a plurality of protruding teeth 8 evenly distributed along the circumference, the flame-retardant protective outer layer 2 The flame retardant protective outer layer includes: a fireproof coating 3 coated on the insulating layer 2, and an outer protective layer 4 coated on the fireproof coating 3.

[0021] The insulating layer 2 is a 105°C radiation cross-linked halogen-free low-smoke flame-retardant polyolefin insulating layer 2; the fire-retardant coating 3 is made of a cable fire-retardant coating, and the outer sheath 4 is a halogen-free flame-retardant nylon sheath.

[0022] The conductor 1 is a flexible conductor formed by twisting a single wire or multiple strands of w...

Abstract

The invention relates to a wiring wire with a flame-retardant protective outer layer. The flame retardant protective outer layer includes: a fire retardant coating coated on the insulating layer, and an outer sheath coated on the outside of the fire retardant coating. It relates to a flame retardant and protective outer layer manufacturing device for the above-mentioned cloth wire with a flame retardant protective outer layer, comprising: a controller, an outer sheath coating device arranged in sequence from front to back, a heating and drying device, a fireproof coating Layer dip coating device. The cloth wire with the flame-retardant protective outer layer has good flame-retardant and fire-proof performance, and is not easy to cause insulation damage during installation and construction.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wiring wire with a flame retardant protective outer layer and a device for making the flame retardant protective outer layer. Background technique [0002] The structure of the cloth wire can be understood from an insulated wire cloth disclosed by the utility model of application number: 202022187588.X; the traditional wire cloth has a simple structure, only an insulating layer outside the conductor, and there is no protection outside the insulating layer, and there is a relatively low flame retardant and fire resistance performance. It is easy to burn in the event of a fire, and it cannot effectively suppress and block the flame. It is easy to cause insulation damage during the installation and construction process, which increases the safety hazard. Therefore, it is not easy to design a flame retardant and fireproof performance during the installation and construction process. ...
