Core structural characteristics
- The conductor is made of stranded high-purity oxygen-free copper wire. Three main core wires carry the main power, and one auxiliary core wire adapts to the three-phase four-wire distribution system, ensuring stable and efficient current transmission.
- The core is wrapped with a high-temperature resistant insulation layer, and the exterior is covered with a metal armor layer and a red fire-resistant outer sheath. The dual protection can withstand flame burning, mechanical impact, and moisture corrosion.
- Both the insulation layer and the sheath are made of fire-resistant and flame-retardant materials, ensuring normal power supply for a period of time in case of a fire, thereby providing support for personnel evacuation and emergency operation of equipment.
performance advantage
- Having undergone rigorous fire resistance testing, it maintains circuit integrity under specified flame temperatures and durations, meeting fire protection standards for critical settings such as high-rise buildings and rail transit.
- The metal armor structure significantly enhances the cable's resistance to compression and stretching, ensuring stable operation even under complex conditions such as direct burial and tray laying.
- The low resistance characteristic of high-purity copper core effectively reduces transmission loss, enhances power utilization efficiency, and is suitable for medium and low voltage power distribution systems.
Applicable scenarios
It is particularly suitable for fields with strict requirements for power supply safety and fire resistance, such as high-rise building power distribution, underground rail transit, hospital emergency power supply, and data center backup power supply. It can also be used for laying main lines in factory workshops and commercial complexes.
