It is necessary to bear the external force of the machine and add the steel tape armor.
Features: In the case of open flame burning, remove the fire source, ≤ 12s automatically extinguished.
It can be laid indoors, in tunnels, and in pipelines, and can withstand certain laying traction, but the cable can not bear external force, and single-core cable is not allowed to be laid in the magnetic material pipeline.
It is necessary to withstand the action of mechanical external force and to wrap around the steel belt.
Features: In the case of open flame burning, remove the fire source, ≤ 12s automatically extinguished.
Can be laid indoors, in tunnels, cable trenches, and pipelines, flammable and severely corroded, but can not withstand mechanical external forces.
