The low melting point tin bismuth alloy is made into small particle containers, superfine dry powder is filled in the small particle containers, and the low melting point tin bismuth alloy particles containing the superfine dry powder are embedded into the optical cable sheath to form the intelligent fire-extinguishing optical cable. When fire occurs around the optical cable, the temperature rises to reach
138
Above the temperature, the particle container is broken, and the superfine dry powder agent is sprayed out and suspended in the air to form aerosol for extinguishing fire.
As an improvement of the invention, the framework grooves are arranged in a columnar structure, and the cross sections of the framework grooves are in a quadrangle star shape.
As an improvement of the invention, the subunit outer diameter is
1.0-1.5mm
。
Compared with the prior art, the invention has the following advantages:
1
) The technical scheme can customize the length of each floor subunit according to the height of the floor, reduces the waste of optical cables, saves resources, is economic and environment-friendly, and has different subunit lengths, wherein the short subunit is used for a low floor, and the long subunit is used for a high floor;
2
) According to the technical scheme, the subunits are produced by adopting a low-friction material, and the low-friction framework groove is used as a reinforcing piece, so that the subunits can be conveniently drawn out after wiring;
3
) This optical cable has intelligent fire extinguishing function, in case take place the condition of a fire, this scheme can intelligent fire extinguishing, in time eliminates conflagration hidden danger, avoids the loss further to enlarge, and this technical scheme cost is lower, the large-scale popularization and application of being convenient for.
