Metal Sheath Inorganic Insulation Mineral Cable


---Flexible Fire Proof Cable


 


 


1. Structure sketch for flexible fire proof cable


1) Cable conductor: It is made up of stranded copper wires, with favorable flexural property.


2) Insulation layer: It adopts high-temperature resistant inorganic insulating materials.


3) Inorganic stuffing: It adopts special stuffing material - inorganic insulating materials


4) metal armour: It is made of mental materials of extruded aluminium tube with favorable corrosion protection.


5) LSHF outer sheath layer
