BTGZ,YTGRZ,YTTW,BTGZ fexible mineral insulated freproof cable is diferent from other common cables in use of high power e-beam(B ray) from high-pow-er electron accelerator for cross-link treatment of inorganic compound with special formulations,which enable the cable to withstand the operating temperature up to 125°C.The fre-resistance of BTGZ,YTGRZ has been greatly improved without the sacrifc of fexibility,which enables the cable under 1,000V to with stand the fame of 950°C for 3 hours and to resist the sprinkle and mechanical crash.
Fire Retardant Properties: These cables are treated with fire retardant materials, reducing the spread of flames and limiting smoke generation.
Corrugated Design: The corrugated structure can enhance flexibility and durability, making the cable easier to install in tight spaces while providing additional protection against physical damage.
Copper Conductors: Copper is known for its high conductivity, making these cables suitable for various applications requiring efficient power transmission.
Temperature Resistance: They can withstand high temperatures without degrading, ensuring safety and reliability.
Commercial and Industrial: Used in buildings, factories, and processing plants where fire safety is crucial.
Transportation: Ideal for railways and other transport systems to ensure passenger safety.
Power Distribution: Suitable for applications where fire safety and efficient power transmission are both critical.
