Description
Technical field
This utility model relates to power cable technical field, particularly relates to a kind of fire resistant communication cable.
Background technology
Along with the development of society, cable is visible everywhere in the life of people, can be divided into power cable, communication cable and control cable etc. by its purposes. Rise especially as digital information industry, the important bridge that communication cable transmits as data, reliability and safety that its data are transmitted by people are increasingly paid attention to, when carrying out comprehensive wiring, wiring personnel especially to consider the cable sudden anti-shot ability in carrying out data transmission process, wherein, " fire prevention " is the important sudden anti-shot ability that cable needs to possess.
But, existing cable is mainly made up of following 4 parts:
1. conductor wire core: make with high conductivity material (copper or aluminum). According to laying the requirement to cable softness of the use condition, every core is likely to be formed by solid conductor or multiple conducting wires are stranded.
2. insulating barrier: the insulant as cable should have high insulation resistance, high breakdown field strength, low dielectric loss and low dielectric constant. Insulant conventional in cable has oil-paper, polrvinyl chloride, polyethylene, crosslinked polyethylene, rubber etc. Cable is often classified with insulant, for instance oil-impregnated paper insulation cable, polyvinyl chloride cable, twisted polyethylene cable etc.
3. sealing sheath: protection insulated wire cores is from the damage of machinery, moisture, moisture, chemical substance, light etc. For the insulation of moisture-sensitive, it is generally adopted lead or aluminium extrusion sealing sheath.
4. cover layer is protected: in order to protect sealing sheath from mechanical damage. Being generally adopted galvanized steel strip, steel wire or copper strips, copper wire etc. and surround sheath outer (title armored cable) as armor, armor plays electric field shielding simultaneously and prevents the effect of external electromagnetic wave interference. In order to avoid steel band, steel wire are by the corrosion of surrounding media, it are typically in outside them pitch or hold macerated jute layer or extruded polyethylene, pvc sheath.
