Abstract
The utility model relates to a power cable field specifically is a high performance fire resisting cable, characterized by: it includes three insulation core, and every insulation core includes fan -shaped stranded conductor, and fan -shaped stranded conductor wraps up outward in proper order has first insulation layer, second insulating layer, and three insulation core hank wraps up outward with the cable core that forms in proper order has band, copper sheath and oversheath, is equipped with the filler between the three insulation core. This cable is at the mica tape crowded package pottery vitrification plastic insulation in insulating outside, therefore receives moisture to influence little, damp proof insulation to make good use of, can effectively prevent the mica tape installation of cable lay with the use in the moisture absorption and have better refractiveness.
Description
Technical field
This utility model is related to power cable field, specifically a kind of high-performance flame-resistant cable.
Background technology
With social progress and expanding economy, energy industry has obtained sending out at a high speed as the basic industry of economic development
Exhibition, the demand of last decade cable is substantially increased.Because the insulating barrier of cable and sheath are typically by flammable plastics or rubber material
Material is made, therefore being continuously increased with cable usage amount, particularly in the place that cable laying is intensive, easily because of cable fault
Cause fire.As in executive information systems, often cluster laying is in cable passage, once there is fire, fiery for cable
Flame will prolong combustion along cable and spread to other positions and other floors, so that the intensity of a fire is expanded, thus causing heavy economic lossess, sternly
Threaten orthobiosiss and the life security of people again.For another example, in power plant, communication system, large industrial enterprise, cable is general
In cable duct, once fire occurs, flame will spread in cable duct cluster laying, its burning extent up to thousands of rice, no
But burn cable, and cause large-area power-cuts, plant downtime, causes huge economic losses.The burning of therefore electric wire is
One of main inducing of electrical fire, has caused the great attention of many social sectors such as fire-fighting.As airport, harbour,
The emergency power supplies of system such as ferrum, nuclear power station, mine, petroleum chemical enterprise, the control of skyscraper, supervision, guiding and warning, fire-fighting electricity
Source, communication system power supply etc., usually require that and still can maintain circuit normal work for a period of time under burning condition, need for this
Fire-resisting cable to be used.
Content of the invention
The purpose of this utility model patent is, provides a kind of high-performance flame-resistant cable, solves impact fire-resisting cable long-term
The stable technical problem using.
In order to achieve the above object, this utility model is realized in：
A kind of high-performance flame-resistant cable, it includes three insulated wire cores, and each insulated wire cores includes fan-shaped stranded conductor, fan
Be enclosed with the first insulating barrier, the second insulating barrier outside shape stranded conductor successively, three insulated wire cores twist and cable core outside successively
It is enclosed with band, copper sheath and oversheath, between three insulated wire cores, be provided with implant.
Described high-performance flame-resistant cable, insulated wire cores include the conductor wire core that the 2nd class copper conductor is made；First insulating barrier
For wrapped inorganic mineral synthetic mica tape；Second insulating barrier is to extrude ceramic plastics；Implant is glass cord；Band is
Glass fiber tape, copper sheath are vertical pack arrangement and are welded with argon arc welding, surface has embossing；Oversheath gathers for low-smoke non-halogen flame-retardant
Alkene sheath.
Due to the easy moisture absorption of mica tape, thus existing fire-resisting cable is often because of the moisture absorption or used during mounting and installation
The moisture absorption after copper sheath accidental damage in journey and affect insulate electrical property, even result in cable cisco unity malfunction.This cable is in cloud
Ceramic plastic insulation is extruded, its advantage is as follows outside master tape insulation：
（1）Ceramic plastic insulation performance is good, and affected by moisture is little, and breakdown strength is higher than mica tape, thus can reduce
Cable insulation thickness, and the electric property of compound inslation is better than pure Muscovitum tape insulation；
（2）Ceramic plastics damp proof insulation acts on, and can effectively prevent mica tape from inhaling during cable installation and use
Tide；
（3）Mica tape fragility is big, extrudes ceramic plastic insulation and mica tape in cabling process can be avoided to crush；
（4）Ceramic plastics magnetize more than 500 DEG C, and refractory temperature reaches 1000 DEG C, thus cable has preferably
Fire resistance.
Brief description
Fig. 1 is the structure sectional view one of this cable.
Fig. 2 is the structure sectional view two of this cable.
Specific embodiment
Further illustrate this utility model below by way of specific embodiment.
As shown in figure 1, a kind of high-performance flame-resistant cable, it includes three insulated wire cores, and each insulated wire cores includes sector
Stranded conductor 1, fan-shaped stranded conductor 1 is outer to be enclosed with the first insulating barrier 2, the second insulating barrier 3 successively, three insulated wire cores twist and and
It is enclosed with band 4, copper sheath 5 and oversheath 6 successively outside the cable core becoming, between three insulated wire cores, be provided with implant.
Described high-performance flame-resistant cable, insulated wire cores include the core that the 2nd class copper conductor is made；First insulating barrier 2 is
Wrapped inorganic mineral synthetic mica tape；Second insulating barrier 3 is to extrude ceramic plastics；Implant is glass cord；Band 4 is
Glass fiber tape, copper sheath 5 are vertical pack arrangement and are welded with argon arc welding, surface has embossing；Oversheath 6 is low-smoke non-halogen flame-retardant
Polyolefin jacket.
As shown in Fig. 2 above-mentioned high-performance flame-resistant cable also has single conductor wire core form, specifically in single conductor wire
The first insulating barrier, the second insulating barrier, band, copper sheath and oversheath is wrapped up successively outside core.
