Description
Technical field
The utility model is related to cable machinery fields, and in particular to a kind of fireproof environmental cable.
Background technology
As electronics technology product and its intelligentized development are universal, people are right to the needs of fast transfer of data, information
Computer, word processor, fax, the dependence of sensor and communication equipment significantly rapidly increase, and new technology makes
The equipment of this respect is online and networking is possibly realized, and results in the comprehensive development of communication system, these systems are in specific area
Use increase, such as skyscraper, ship, aircraft, train, drilling platforms and mine.In order to connect these electronic components, need
A large amount of electric wire and cable is used in these structures and field.Common cable is especially under certain emergency cases at present,
Such as under the high-temperature condition of fire generation, just it is easy to make existing cable bad, cable fire-proof heat resistance is insufficient, in practical hair
When calamity of lighting a fire energization can not be ensured once burned.
Invention content
The utility model proposes a kind of fire resistant flexible environment-friendly cables, have preferable fireproofing and heat resistant, simple in structure, at
This is relatively low, environmental protection.
Technical solution used by the utility model is as follows：
A kind of fire resistant flexible environment-friendly cable, including cable core, the cable core are twisted by more hot-face insulation cores,
In, the hot-face insulation core includes copper conductor, flame retardant coating and insulating layer from inside to outside, and the cable core is externally provided with shielded layer,
Around cable core be equipped with a plurality of flame-retardant strip, the gap of cable core, flame-retardant strip and shielded layer be equipped with filling, by shielded layer outward according to
It is secondary to be equipped with the first alkali-free glass fiber band, double-layer ceramic fire guard, the second alkali-free glass fiber band and protective layer.
Further, the flame-retardant strip is low smoke and zero halogen adhesive tape.
Further, described to be filled with alkali-free glass wool.
Further, the shielded layer uses tinned copper wire braid over braid.
Further, the fire resisting layer material is calcining muscovite.
It is of the utility model to have the beneficial effect that：
This cable is equipped with flame-retardant strip around cable core, improves fire resistance, and fill using alkali-free glass wool, more favorably
It radiates in cable, and there is the good feature of environmental protection.Using double-layer ceramic fire guard, better heat-insulated oxygen-impermeable work can be played
With, it is ensured that cable normal operation is extruded in outside double-layer ceramic fire guard with two layers of alkali-free glass fiber band, in cable by fire
When, prevent the ceramic body hardened embrittlement under external impacts from falling off, to protect the safe to use of the cable.To sum up institute
It states, this construction of cable is simple, and processing easy to produce, cost is relatively low, has preferable fireproofing and heat resistant and the feature of environmental protection.
Description of the drawings
Fig. 1 show the structural schematic diagram of the utility model.
Wherein, 1- cable cores, 101- copper conductors, 102- flame retardant coatings, 103- insulating layers, 2- flame-retardant strips, 3- fillings, 4- shieldings
Layer, 5- the first alkali-free glass fiber bands, 6- double-layer ceramic fire guards, 7- the second alkali-free glass fiber bands, 8- protective layers.
Specific implementation mode
A kind of fire resistant flexible environment-friendly cable, including cable core 1, the cable core 1 are twisted by more hot-face insulation cores,
In, the hot-face insulation core includes copper conductor 101, flame retardant coating 102 and insulating layer 103 from inside to outside, and the cable core 1 is externally provided with
Shielded layer 4 is equipped with a plurality of flame-retardant strip 2 around cable core 1, and filling is equipped in cable core 1, flame-retardant strip 2 and the gap of shielded layer 4
3, by shielded layer 4 outward successively be equipped with the first alkali-free glass fiber band 5, double-layer ceramic fire guard 6, the second alkali-free glass fiber band 7, and
Protective layer 8.
Further, 102 material of the flame retardant coating is calcining muscovite, and mica content is high, and volume resistivity is larger, tool
Standby certain insulation performance, fire resistance is very reliable, good environmental protection.
Further, the flame-retardant strip 2 is low smoke and zero halogen adhesive tape, and content of halogen is lower, does not generate a large amount of dense smokes after burning,
Good environmental protection.
Further, the filling 3 is alkali-free glass wool, is filled using alkali-free glass wool, while fire resistance improves
It is more advantageous to cable heat dissipation.
Further, the shielded layer 4 uses tinned copper wire braid over braid.
Using double-layer ceramic fire guard 6, can play the role of preferably it is heat-insulated oxygen-impermeable, when cable is by fire,
The fire guard hardens into ceramic body, to which the inside and outside matter and energy of isolation transmits, it is ensured that cable normal use.With the first alkali-free glass
Fibre ribbons 5 and the second alkali-free glass fiber band 7 are extruded in outside double-layer ceramic fire guard 6, when cable is by fire, are prevented firmly
The embrittlement under external impacts of the ceramic body of change falls off, to protect the safe to use of the cable.
