Description
Technical field
The present invention relates to technical field of electric wires and cables, be specifically related to a kind of isolated form fire retardant cable working technology.
Background technology
In prior art, cotton covered wire typically uses polrvinyl chloride as insulation.This cotton covered wire is owing to its construction features is with exhausted
Edge Flame Retardancy can limit, and bunchy fire resistance can only pass through GB/T18380B class, it is impossible to passes through GB31247B1Level.At fire
When calamity occurs, the cotton covered wire that bunchy lays once burns, and prolongs combustion distance, and burning produces amount of heat and cigarette, can aggravate fire
Harm, it is difficult to strive for the longer time for escape and rescue.And low-smoke halogen-free polyolefin insulating cotton covered wire due to use low cigarette without
Halogen polyolefin, as insulation, solves the problem that smoke-producing amount when catching fire is the biggest, but flame retardant effect still can only pass through GB/
T18380B class, it is impossible to pass through GB31247B1Level.Low-smoke halogen-free polyolefin material with the addition of a large amount of magnesium hydroxide, hydrogen-oxygen simultaneously
Changing aluminum fire retardant, macromolecular chain binding strength is deteriorated, and between macromolecular chain, gap becomes big, and the mechanical performance of material is substantially reduced (draws
Stretch intensity and only have 10MPa), water penetration is greatly increased, and about reduces by two numbers than PVC electric wire insulation resistance after electric wire immersion
Magnitude.And existing electric wire heat dispersion is poor, is not easy to fix when many electric wires are put together.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of isolated form fire retardant cable working technology.
A kind of isolated form fire retardant cable working technology that the present invention proposes, comprises the following steps:
A), by conductor wire drawing and anneal；

Preferably, described isolated form fire retardant cable working technology is further comprising the steps of:
D), by multiple regions of Ceramic silicon rubber outer layer along its circumference skiving, multiple diversion division is formed.
Preferably, step D) in, diversion division skiving to the distance between itself and conductor is equal between bar-shaped trough and conductor
Distance.
Preferably, described isolated form fire retardant cable working technology is further comprising the steps of:
E), heat discoloration coating will be coated on the outer wall of Ceramic silicon rubber correspondence diversion division.
The present invention is at the fire-retardant sealing coat of insulating barrier outer cladding, and Ceramic silicon rubber of once catching fire at high temperature can be formed does not fires
Shelly porcelain body, stop flame invasion and attack cable insulation, there is good flame resistance, dielectric strength is high, water resistance is good, burning heat production
The features such as smoke-producing amount is little, can meet important events fire-resistant wire needs.The present invention achieves cable by the way of simple and fast
Processing, and cable waterproof fireproof performance can be effectively improved.
Accompanying drawing explanation
The structural representation of a kind of isolated form produced cable of fire retardant cable working technology that Fig. 1 proposes by the present invention.
Detailed description of the invention
A kind of isolated form fire retardant cable working technology that the present invention proposes, comprises the following steps:
