Embodiment Construction

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

[0020] Such as figure 1 Shown: a kind of electrical wiring with a flame-retardant protective outer layer, including: a conductor 1, an insulating layer 2 wrapped around the outer conductor 1 and provided with a plurality of protruding teeth 8 evenly distributed along the circumference, and a flame-retardant protective outer layer layer; the flame-retardant protective outer layer includes: a fire-resistant coating 3 coated on the outside of the insulating layer 2, and an outer protective layer 4 coated on the outside of the fire-resistant 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 material of the fireproof coating 3 is cable fireproof coating, and the outer sheath 4 is a halogen-free flame-retardant nylon sheath layer.

[0022] The conductor 1 is a single wire or...

Abstract

The invention relates to a cotton covered wire with a flame-retardant protective outer layer. The cotton covered wire comprises a conductor, an insulating layer and the flame-retardant protective outer layer, wherein the insulating layer wraps the conductor, and twenty to thirty convex teeth distributed along the circumference are arranged in the outer side of the insulating layer in a surrounding manner; and the flame-retardant protective outer layer comprises a fireproof coating coated outside the insulating layer and an outer protective layer coated outside the fireproof coating. A related flame-retardant protective outer layer manufacturing device for the cotton covered wire with the flame-retardant protective outer layer comprises a controller, and an outer protective layer coating device, a heating and drying device and a fireproof coating dip-coating device which are sequentially arranged from front to back. The cotton covered wire with the flame-retardant protective outer layer is high in flame-retardant and fireproof performance, and insulation damage is not prone to being caused in the installation and construction process.

Description

technical field [0001] The invention relates to the technical field of electric cables, in particular to a wire distribution 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 wiring can be obtained from a kind of insulated wiring disclosed in the utility model with the application number: 202022187588.X; the traditional wiring structure is simple, there is only an insulating layer outside the conductor, and there is no protection outside the insulating layer. Poor, it is easy to burn in the event of a fire, it cannot effectively suppress and block the flame, it is easy to cause insulation damage during the installation and construction process, and increase the safety hazard; The electrical wiring with flame-retardant protective outer layer and the manufacturing device of flame-retardant protective outer layer that cause insulation damage have become problems to...
