Description
Technical field
The utility model is related to electricity, the essential electronic element that metal wire or metal tape make, espespecially a kind of low smoke and zero halogen
Cable.
Background technology
Cable is to be placed in the insulated conductor constituted in sealing sheath by the conducting wire center of one or more mutually insulated, outside it
Protection coating can be added, for transmitting, distributing electric energy or transmission electric signal, it is mainly cable dimension with the difference of common wiring
Larger, structure is more complicated.
Cable is mainly made up of following 4 part, 1. conducting wire center：Use high conductivity material（Copper or aluminium）It is made, according to deposited
If requirement of the use condition to cable softness, the every line heart may be formed by solid conductor or multiple conducting wires are stranded, 2. absolutely
Edge layer：Insulating materials as cable should have an insulaion resistance high, breakdown field strength high, low dielectric loss and low
Dielectric constant, in cable commonly use insulating materials have oil-paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber etc., electricity
Cable is often classified with insulating materials, such as oil-impregnated paper insulation cable, polyvinyl chloride cable, twisted polyethylene cable etc., 3. sealing shield
Set：Protect protection insulated wire heart from the damage of machinery, moisture, moisture, chemical substance, light etc., for the insulation of moisture-sensitive, typically adopt
With lead or aluminium extrusion sealing sheath, coating is 4. protected：It is used to protect sealing sheath from mechanical damage, typically using galvanized steel
Band, steel wire or copper strips, copper wire etc. are surrounded outside sheath as armor（Claim armored cable）, armor is while playing electric field shielding and preventing
The only effect of external electromagnetic wave interference, in order to avoid steel band, steel wire are corroded by surrounding media, is typically coated with drip outside them
Blue or green or wrapping macerated jute layer or extruded polyethylene, polyvinyl chloride set.
Due to using PVC existing common cable insulating barrier and oversheath, causing to cause smoke big when fire, combustion more
Burn generation sour gas and titanic peril is caused to rescue, while the oversheath resistance to mechanical degraded performance of common cable, easy stabbing
Prick.
The content of the invention
The utility model provides a kind of low-smoke halogen-free cable regarding to the issue above, and the product structure reasonable standard passes through
Use polypropylene, oversheath to use crosslinked polyethylene and Graphene insulating barrier, reduce the smoke amount of cable fire, it is to avoid cause
Secondary hazards, graphene layer has the mechanical property of super brother, good thermal conductivity, high resistance to weather, thorn resistance energy.
To solve the above problems, the utility model provides a kind of low-smoke halogen-free cable, including body, cable core, conductor,
Separation layer, internal shield, polypropylene layer, packed layer, graphene layer, it is characterised in that：Body interior is provided with some cables core,
Packed layer is provided between adjacent cable core, cable core is internally provided with conductor, and conductor outside surfaces are provided with separation layer, separation layer
Outer surface is provided with internal shield, and internal shield outer surface is provided with polypropylene layer, and twining package tape is provided with outside packed layer, wrapped
