Abstract
The utility model discloses a fire -retardant fire -resistant shielded cable of infiltration formula, including sinle silk, asbestos layer, dress liquid layer, sinle silk transposition together, sinle silk outside cladding has around the covering, has a shielding layer around the covering outside, there is an asbestos layer in the shielding layer outside, there is a dress liquid layer in the asbestos layer outside, the dress liquid layer has the oversheath outward, the dress liquid layer comprises main part membrane and blister cavities, the blister cavities inlays in the main part membrane, and the blister cavities outer end is located the outside of main part membrane, and blister cavities the inner is located the inboard of main part membrane. The utility model discloses a dress liquid layer that will be equipped with fire prevention oil sets up in the asbestos layer outside for cable high temperature and when having catch fire dangerous, fire prevention oil can soak into the asbestos layer makes the cable be difficult for catching fire, the epimembranal distribution of main part has a plurality of through -holes for the oily infiltration asbestos layer that can be smooth of fire prevention, blister cavities outer end wall thickness is greater than the inner wall thickness of blister cavities makes most of blister cavitiess to break in blister cavities the inner, has made things convenient for the oily moist asbestos layer of fire prevention.
Description
[technical field]
This utility model relates to the technical field of the technical field of cable, particularly flame resistant cable.
[background technology]
Cable needs to ensure the integrity of insulation in running, if insulation sustains damage, is then susceptible to
The situation such as puncture, cause the phenomenon such as short circuit, electric leakage.Send out because of a variety of causes inside Exterior cable or cable
When life is caught fire, if can not put out a fire timely, then easily cause insulation impaired, bring adverse influence.Existing
Cable-flame retardant fire resistance not ideal enough.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of infiltration type flame-retardant
Shielded cable, it is possible to make cable have preferable flame-retardant performance.
For achieving the above object, the utility model proposes a kind of infiltration type flame-retardant shielded cable, including
Core, asbestos layer, dress liquid layer, described core twists together, and is coated with lapping layer outside core, wrapped
There is screen layer outside Ceng, outside screen layer, have asbestos layer, have dress liquid layer outside asbestos layer, outside having outside dress liquid layer
Sheath, described dress liquid layer is made up of body membrane and blister cavities, and described blister cavities is embedded in body membrane, position, blister cavities outer end
In the outside of body membrane, blister cavities the inner is positioned at the inner side of body membrane.
As preferably, some through hole being distributed in described body membrane, blister cavities outer end wall thickness is more than blister cavities inner end wall
Thick.
As preferably, described core by the stranded conductor being sequentially distributed from inside to outside, Muscovitum belt, fire-retardant absolutely
Edge layer forms.
As preferably, described blister cavities, built with F R Oil, is evenly distributed with hole in asbestos layer.
The beneficial effects of the utility model: this utility model is arranged on stone by will be equipped with the dress liquid layer of F R Oil
Outside cotton layer so that cable temperature too high and have catch fire dangerous time, F R Oil can infiltrate asbestos layer so that
Cable is difficult to catch fire；Some through hole is distributed so that F R Oil can infiltrate asbestos layer smoothly in body membrane；
Blister cavities outer end wall thickness makes most of blister cavities can rupture in blister cavities the inner more than blister cavities the inner wall thickness, facilitates anti-
Kerosene infiltration asbestos layer.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the structural representation of this utility model a kind of infiltration type flame-retardant shielded cable；
Fig. 2 is the dress liquid layer schematic diagram of this utility model a kind of infiltration type flame-retardant shielded cable.
In figure: 1-core, 2-lapping layer, 3-asbestos layer, 4-dress liquid layer, 5-oversheath, 11-stranded conductor,
12-Muscovitum belt, 13-flame retardant insulation, 20-screen layer, 40-through hole, 41-body membrane, 42-blister cavities.
[detailed description of the invention]
Refering to Fig. 1 and Fig. 2, this utility model one infiltration type flame-retardant shielded cable, including core 1,
Asbestos layer 3, dress liquid layer 4, described core 1 twists together, and is coated with lapping layer 2 outside core 1, around
There is screen layer 20 outside covering 2, outside screen layer 20, have asbestos layer 3, outside asbestos layer 3, have dress liquid layer 4,
Oversheath 5, described dress liquid layer 4 is had to be made up of body membrane 41 and blister cavities 42 outside dress liquid layer 4, described blister cavities
42 are embedded in body membrane 41, and blister cavities 42 outer end is positioned at the outside of body membrane 41, and blister cavities 42 the inner is positioned at master
The inner side of body film 41, is distributed some through holes 40 in described body membrane 41, blister cavities 42 outer end wall thickness is more than capsule
The inner wall thickness in chamber 42, described core 1 by the stranded conductor 11 being sequentially distributed from inside to outside, Muscovitum belt 12,
Flame retardant insulation 13 forms, and described blister cavities 42, built with F R Oil, is evenly distributed with hole in asbestos layer 3.
Utility model works process:
This utility model one infiltration type flame-retardant shielded cable in the course of the work, when cable is because of various former
Thus temperature is too high when having fire hazard, blister cavities 42 can rupture, owing to blister cavities 42 outer end wall thickness is more than blister cavities
42 inner wall thickness make most of blister cavities 42 can rupture in blister cavities 42 the inner, and F R Oil can overflow and infiltrate stone
Cotton layer 3, the F R Oil that minority is overflowed because blister cavities 42 outer end ruptures by the through hole 40 in body membrane 41 with
Asbestos layer 3 contacts, and infiltrates asbestos layer 3, and the asbestos layer 3 after infiltration not only has good fire resistance, also
Make outside air and the air insulated within asbestos layer 3 so that core 1 is nonflammable, have well
Fire resistance.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any to this
Scheme after utility model simple transformation belongs to protection domain of the present utility model.
