Product Description

Product Description

1.Core Construction & Material Excellence
BTTZ Cable (Heavy Duty Copper Core Copper Sheath Magnesium Oxide Mineral Insulated Cable) features an all-inorganic structure:
   Conductor: High-purity copper core ensures superior conductivity.
   Insulation: Compressed magnesium oxide (MgO) powder provides exceptional dielectric strength and thermal stability 
   Sheath: Seamless copper tubing offers robust mechanical protection and acts as an integrated grounding path, eliminating the need for a separate ground wire .

2. Unmatched Fire Performance & Safety

Designed for critical fire scenarios:
   Continuous operation at 250°C and short-term survival (30 minutes) at extreme temperatures up to 1,000°C .
   Fireproof, explosion-proof, and non-combustible, ensuring circuit integrity during fires (tested up to 180 minutes) .
   Zero toxic smoke or halogen emissions, enhancing evacuation safety.

3. Superior Electrical & Mechanical Properties
   High current-carrying capacity and minimal signal attenuation due to low impedance .
   Crush-resistant and corrosion-proof copper sheath, suitable for harsh environments .
   Extended service life (>50 years) with inorganic materials immune to aging .

4. Key Applications
Ideal for life-safety systems in:
   Building fire protection circuits (alarms, smoke extraction, emergency lighting) .
   High-rise vertical risers, power distribution in commercial complexes, and industrial plants .
   Hazardous locations (petrochemical plants, tunnels) requiring explosion-proof certification.

5. Competitive Advantages
   Space-efficient: Compact outer diameter reduces installation space vs. conventional cables .
   Self-grounding: Copper sheath simplifies grounding compliance .
   Compliance: Meets GB/T 13033 (China) and IEC 60702 standards (note: IEC requires ≥99.9% copper purity vs. GB's ≥99.5%) .
   Low maintenance: Immune to moisture, rodents, and UV degradation.
Note: Requires careful handling (bending radius ≥6× cable diameter) due to rigid construction .
