Abstract
The invention discloses a fire-resistant high-flame retardant optical cable. The fire-resistant high-flame retardant optical cable comprises a cable core, a water blocking tape, thermal insulation tapes, a polyolefin sheath and a polyolefin protective layer, wherein the cable core is composed of a central reinforcer and loose sleeves; the plurality of loose sleeves, with the central reinforcer adopted as a center, are stranded on the central reinforcer in an enclosing manner; optical fibers are arranged in each loose sleeve; a plurality of water blocking yarns are arranged at the exterior of the central reinforcer; the water blocking tape, the polyolefin sheath and the polyolefin protective layer coat the cable core from inside to outside sequentially; one thermal insulation tape is arranged between the water blocking tape and the polyolefin sheath; and one thermal insulation tape or one steel wire armoring layer is arranged between the polyolefin sheath and the polyolefin protective layer. When being burnt in fire, the optical cable will not generate toxic gases and smoke, and at the same time, ceramifiable polyolefin and the mica thermal insulation tapes can prevent outside high temperature from being transferred to the cable core, so that normal communication will not be affected by the high temperature, and ceramifiable mica can be ceramified when temperature reaches above 500 DEG C, and the ceramified optical cable can withstand temperature abrupt drop in fire extinguishment, and has good impact resistance and can ensure normal communication.
Description
Technical field
The present invention relates to a kind of fire-resistant high fire-retardance optical cable.
Background technology
Along with social development, 4G speeds up the construction, cloud computing etc., information carring capacity is increasing, the capacity of the data center of information processing is the most increasing, information data center needs substantial amounts of transmission and the cable of equipment room interconnection, and manufacture the insulation of these cables and sheath material is mainly rubber and high molecule plastic polymer, they majorities are easily to burn and prolong combustion, frequent generation due to electrical fire accident, toxic gas and dense smoke can be produced during the burning of these cables, the life security of grave danger people, the fire-retardant problem of cable the most gradually causes the attention of countries in the world.
Summary of the invention
It is an object of the invention to provide a kind of fire-resistant high fire-retardance optical cable.
The technical solution used in the present invention is:
A kind of fire-resistant high fire-retardance optical cable, it is characterized in that: include by center reinforcement, the cable core of Loose tube composition and waterstop, heat insulating belt, polyolefin jacket, polyolefin sheath, described some Loose tube centered by the reinforcement of center on the reinforcement of Jiao Yu center, in described Loose tube, optical fiber is set, some water blocking yarns are set outside the reinforcement of described center, described waterstop, polyolefin jacket, polyolefin sheath is coated on cable core the most successively, described waterstop with, heat insulating belt is set between polyolefin jacket, heat insulating belt or steel wire armor layer are set between described polyolefin jacket and polyolefin sheath.
The material of described Loose tube is low-smoke halogen-free polyolefin.
The material of described heat insulating belt is can porcelain Muscovitum.
