Product Description
Product introduction
Conductor | • Solid copper |
Insulation | • Mineral (MgO) insulation material |
Sheath | • Copper Sheath |
Characteristics of BTTZ
1.Heat resistance: The cable can endure flame at 950-1000℃ 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 1300℃)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 1083℃)which prevents the insulation from being loose or
burned under fire conditions and thus maintain the circuit integrity.
