Description
Technical field
The utility model patent belongs to field of cable technology, is related to a kind of low-smoke non-halogen flame-retardant A class flame-proof control cables.
Background technology
With the development of society, skyscraper is more and more, people realize safety and environmental protection also increasingly stronger, low smoke and zero halogen
Flame retardant cable uses more and more, and when general high-rise building with fire disaster, often most people are not scorched to death, and
It is to be poisoned with poison or be choked to death by smog toxic gas, therefore needs further improvement.
Utility model content
The utility model is in view of the foregoing drawbacks, and it is an object of the present invention to provide one kind, which solves cable, occurs toxic gas when fire
And the generation of a small amount of smog, the retarded combustion time, ensure that the cable work time, escapes from the fire scene and has been reserved fully to people
Time low-smoke non-halogen flame-retardant A class flame-proof control cables.
The technical solution adopted in the utility model is for this：The utility model includes some cores；
The core includes：The conductor twisted together（1）, the conductor（1）One layer of fire-resistant isinglass belt of outer cladding（2）,
The fire-resistant isinglass belt（2）One layer insulating of outer cladding（3）；
The core is externally provided with one layer of lapping layer（4）, the lapping layer（4）It is externally provided with one layer of liner layer（5）, the liner
Layer（5）It is externally provided with braiding layer（6）, the braiding layer（6）It is externally provided with oxygen barrier belt（7）, the oxygen barrier belt（7）It is externally provided with low cigarette
Halogen-free flameproof outer jacket（8）.
The lapping layer（4）Inside it is provided with four cores.
The fire-resistant isinglass belt（2）For fluorophlogopite belt.
The insulating layer（3）For crosslinked polyetylene insulated layer.
The liner layer（5）For low-smoke non-halogen flame-retardant liner layer.
The braiding layer（6）For annealed copper silk braid shielded or it is galvanized steel strip shielding.
The utility model has the advantages that：1. the deisgn product has flame-retarding characteristic, when fire occurs, cable can guarantee that
Continue conduction time, prevent the sprawling of fire, ensure the cable work time, when burning sends seldom cigarette, will not produce poisonous
Gas.
2. the product is equipped with one layer of flame retardant coating, one layer of fluorophlogopite belt is coated on conductor, fusing point reaches 1375
DEG C, it is horizontal to have reached A grades of fire resistings（950-1000℃）, ensure that occur fire it is unexpected when, cable can effectively run compared with
For a long time.
3. the insulation of the product uses crosslinked polyethylene material, outer jacket uses low-smoke halogen-free flame-retardant sheath material.
4. shielded layer uses annealed copper silk braid shielded or is shielded for galvanized steel strip.
