三、产品核心特点

III. Core Product Features

经济可靠：铝合金导体在满足同等导电能力下，相比铜缆显著降低材料成本，且重量更轻，便于运输和安装。
机械性能强：双钢带铠装结构有效抵抗外部压力、冲击和啮齿动物啃咬，特别适合直埋、穿管等有机械防护要求的场合。
安全阻燃：具备C类成束阻燃性能，配合低烟无卤护套材料，能在火灾发生时延缓火焰蔓延，并减少有毒烟雾的产生，提升公共场所安全性。
连接稳定：导体经过特殊退火和表面处理，抗氧化能力强，配合专用连接器，可有效解决接头处的接触电阻和电化学腐蚀问题。
Cost-Effective and Reliable: Compared to copper cables with equivalent conductivity, the aluminum alloy conductor significantly reduces material costs, is lighter in weight, and facilitates transportation and installation.
Strong Mechanical Performance: The double steel tape armor structure effectively resists external pressure, impact, and rodent bites, making it particularly suitable for applications requiring mechanical protection, such as direct burial and conduit installation.
Safe and Flame Retardant: Possesses Class C flame retardancy (bunched cable test), combined with low-smoke zero-halogen sheath material, it can delay flame spread and reduce the generation of toxic smoke during a fire, enhancing safety in public spaces.
Stable Connection: The conductor undergoes special annealing and surface treatment, providing strong oxidation resistance. When used with dedicated connectors, it effectively addresses issues of contact resistance and electrochemical corrosion at joints.
