Model number:MI cable copper conductor mineral insulation fireproof cable BTLY
| Conductor || • copper |
| Insulation || • Mineral (MgO) insulation material |
| Sheath || • Copper Sheath |
Characteristics of BTLY
1.Heat resistance: The cable can endure flame at 950-1000ºC for 3 hour so as to maintain the circuit integrity.
2.Conductor consists of stranded multiple copper wires, featuring small impedance, large ampacity and flexibility.
3.Insulation consists of heat resistant (above 1300ºC)inorganic mineral insulating tapes wound around the conductor, featuring even insulation thickness,high AC voltage withstand,high resistance to electrical and heat aging and long service life.
4.Metal sheath is a corrugated copper sheath (resistant to 1083ºC)which prevents the insulation from being loose or burned under fire conditions and thus maintain the circuit integrity.
Standard fire flexible wiring according to the following:
