The fire resistance of cable, it is ensured that using for cable is safe.
The utility model provides following technical scheme：
A kind of fire resisting cable, including conductor and metal-back, the metal-back also include conductor chamber, and the conductor chamber is located at institute
State in metal-back, the conductor is located at the conductor intracavitary.
It is preferred that, the conductor chamber includes the first conductor chamber and the second conductor chamber, and the middle part of the metal-back is provided with transversal
Face is the first circular conductor chamber, and the first conductor chamber is divided into 4 the second conductor chambers with the gap uniformity of the metal-back,
The conductor is located at the first conductor chamber and the second conductor intracavitary.Conductor is located at different conductor chambers by this structure, is made
Conductor is separated with metal, the fire safety of cable is improved.
It is preferred that, the conductor is with being filled with the first mica layer in the gap of the first conductor chamber；Mica layer has excellent
Good resistance to elevated temperatures and flame resistance energy, and with good toughness.
It is preferred that, the conductor is with being filled with the second mica layer in the gap of the second conductor chamber；Mica layer has excellent
Good resistance to elevated temperatures and flame resistance energy, and with good toughness, it is easy to the bending of cable.
It is preferred that, the conductor periphery is provided with insulating barrier, and the periphery of the insulating barrier scribbles ceramic coating；The insulating barrier
Conductor can be isolated, ceramic coating has high temperature resistant, the fire protecting performance of cable can be improved.
It is preferred that, the metal-back periphery is provided with overcoat, and the 3rd cloud is provided between the overcoat and the metal-back
Mother layer.Metal-back can be isolated from the outside by overcoat, improve safety in utilization, and mica layer has excellent resistance to elevated temperatures and resistance to
Combustibility, and with good toughness, it is easy to the bending of cable.
It is preferred that, the metal-back uses corrugated metal pipe, and the metal-back is formed in one, and corrugated metal pipe is beneficial to
The bending and radiating of cable, are integrally formed life-span and the toughness that can be improved using metal tube
It is preferred that, the overcoat and the insulating barrier use halogen PVC fire proofings, and this structure can further improve
The fire resistance of cable.
Compared with traditional fire resisting cable, this is separated conductor by the first conductor chamber and the second conductor chamber using new,
Ensure that the conductor protective refractory at each position is independent, so as to improve the fire safety of cable.
