3 X 1.5 Mm2 3 X 150 Mm2 Mineral Insulated Power Cable Micc Cable
Mineral Insulated Power Cable is used in distribution circuits in large buildings, rail transit, hospitals, shopping malls, entertainment venues, data centers and other important places
Structure of Mineral Insulated Power 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. Copper sheath: copper materials, through special machining, with favorable flexural property. used as PE wire.
4. Outer sheath: it is made of plastic materials of low-smoke non-toxicity, with favorable corrosion protection.
