Frame, and the surrounding of cross is provided with wire uniformly, described cross be arranged above drain wire, and drain wire is arranged on
Between wire and wire, the right side of described cross is provided with data line, and the lower section of cross is provided with tear rope, institute
State and be connected by sensing line between sensitive unit with data line.
Preferably, described tear rope is arranged between wire and wire.
Preferably, described data line is arranged between wire and wire.
Preferably, described wire is made up of polyethylene insulation set and solid copper conductor, and polyethylene insulation set is arranged on reality
The outside of heart copper conductor.
Preferably, fine cream it is provided with in described liner protection network.
Compared with prior art, the invention has the beneficial effects as follows: use the protection that LSZH LSOH anti-flaming material makes
Set so that surpass five class netting twines and there is low smoke, zero halogen, low smoke and low halogen characteristic, when fire occurs, rate of propagation is slow, and smoke density is low,
Visibility is high, and harmful gas burst size is little, it is simple to personnel withdraw, and the corrosivity of burning gases is little, it also avoid instrument and equipment
Infringement, low halogen, the characteristic of Halogen so that cable material is greatly improved at ageing-resistant and UV resistant and other irradiation behaviour,
Thus extend the service life of cable, being provided with sensitive unit can report to the police timely when fire occurs.
