Product Description

Shengbhua Jiaolian Fireproof High-Voltage Grids Copper Sheath Copper core Electric Wire

The BTTZ Heavy Duty Copper Core Mineral Insulated Fireproof Cable, engineered for unparalleled reliability in extreme conditions, features a copper core with magnesium oxide insulation and a seamless copper sheath, delivering exceptional electrical performance with a voltage rating of 0.6/1kV

 Designed for critical applications such as nuclear power plants, metallurgy, chemical processing, mines, and kilns, its core advantages include superior fire resistance (withstanding temperatures up to 1000°C), robust mechanical strength, and high insulation integrity to prevent short circuits and ensure long-term safety in hazardous environments. Certified to meet CE, RoHS, and international fire safety standards (e.g., IEC 60754).

The cable functions as a dependable power transmission solution with low smoke emission and halogen-free properties, minimizing environmental impact. While standard BTTZ construction utilizes copper core with magnesium oxide insulation and copper sheath, customizable options include copper core polyethylene insulated polyvinyl chloride sheathed variants for specific flexibility or cost-efficiency needs.

 This versatile structure ensures durability against oxidation and mechanical stress, making it ideal for installations where reliability and compliance are paramount
