Abstract
This utility model relates to a kind of electric wire, particularly relates to a kind of fire safe type drag chain cable.A kind of fire safe type drag chain cable, including copper conductor (1), insulating barrier (3) and oversheath (6), the outer wrapped stratus master tape (2) of described single copper conductor, mica tape outsourcing insulation, the first glass tape (4) composition single cable is wrapped again outside insulating barrier, outer wrapped second glass tape (5) after many cable twist, then bag oversheath.Described insulating barrier and oversheath use flame-proof PVC.Described copper conductor is flexible structure.Drag chain cable of the present utility model has good fire protecting performance, can keep one period of effective conduction time, thus reduce the loss of personnel and property under fire hazard environment.
Description
Technical field
This utility model relates to a kind of electric wire, particularly relates to a kind of fire safe type drag chain cable.
Background technology
Existing common drag chain cable simply extrudes one layer of PVC insulating barrier, then by stranded for many single lines on copper conductor
The most additional sheath.Owing to common drag chain cable does not has flame-retardant layer, its fire protecting performance is poor, if running into fire, cable holds very much
Easily it is burned, causes cable dead electricity, thus cause casualties and property loss.Even if some drag chain cables have employed fire-retardant
PVC insulating barrier and oversheath, but its fire resistance can not reach relevant fire protection requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of fire safe type drag chain cable, and this drag chain cable has good fire line
Can, one period of effective conduction time can be kept under fire hazard environment.
In order to realize above-mentioned technical purpose, this utility model adopts the following technical scheme that
A kind of fire safe type drag chain cable, including copper conductor, insulating barrier and oversheath, outer wrapped one layer of described single copper conductor
Mica tape, mica tape outsourcing insulation, wrap again outside insulating barrier first glass tape composition single cable, after many cable twist outside
Wrapped second glass tape, then bag oversheath.
Described insulating barrier and oversheath use flame-proof PVC.
This utility model fire safe type drag chain cable have employed Mica tape on single copper conductor, exhausted at single copper conductor
The outer wrapped heat insulation glass tape of edge layer, outer wrapped heat insulation glass tape again after single cable is stranded so that cable fire-retardant
Performance has been improved, and adds insulating barrier and the PVC of oversheath employing high fire-retardance so that the fire resistance of drag chain cable has had
One step improves, and therefore, this drag chain cable has good fire protecting performance, when can keep one section of effective energising under fire hazard environment
Between, thus reduce the loss of personnel and property.
This utility model fire safe type drag chain cable is applicable on the equipment of electrical equipment or needs movement use.
Accompanying drawing explanation
Fig. 1 is this utility model fire safe type drag chain cable structural representation.
In figure: 1 copper conductor, 2 mica tapes, 3 insulating barriers, 4 first glass tapes, 5 second glass tapes, 6 oversheaths.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
See Fig. 1, a kind of fire safe type drag chain cable, including copper conductor 1, mica tape 2, insulating barrier the 3, first glass tape 4,
2nd 1 glass tape 5 and oversheath 6, the described single outer wrapped stratus master tape 2 of copper conductor 1, extrude environmental protection outside mica tape 2
Flame-proof PVC (polrvinyl chloride) insulating barrier 3, wraps the first heat insulation glass tape 4 again outside insulating barrier 3 and forms single cable, many lines
Outer wrapped second glass tape 5 after cable is stranded, then extrude oversheath 6, oversheath 6 uses the flame-proof PVC of environmental protection.This copper conductor 1
For flexible structure.Owing to have employed 2, two layers of heat insulation glass tape 4,5 of mica tape of one layer of fire protection flame retarding, and flame-proof PVC
Insulating barrier 3 and oversheath 6, therefore, this drag chain cable has good fire protecting performance, can keep one section effectively under fire hazard environment
Conduction time, thus reduce the loss of personnel and property.
These are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model,
Therefore, all any modification, equivalent substitution and improvement etc. made within spirit of the present utility model and principle, should be included in
Within protection domain of the present utility model.
Claims (2)
