二、产品核心特点

II. Core Product Features

轻量化与经济性：采用铝合金导体，相比同规格铜缆（YJV22）重量减轻约 40%，大幅降低运输、搬运及支架成本，工程造价更具优势。
双重安全防护：ZC阻燃特性可在火灾条件下抑制火焰蔓延；22钢带铠装结构提供强大的抗压、抗冲击能力，适合直埋、电缆沟及有机械外力风险的场所。
电气性能稳定：交联聚乙烯（XLPE）绝缘配合 1.8/3kV 中压设计，介电强度高，长期允许工作温度达 90℃，载流量大。
抗蠕变可靠：铝合金导体经过特殊合金化及退火处理，解决了纯铝导体易蠕变、连接处松动的历史难题，连接可靠性接近铜导体。
Lightweight & Cost-Effective: Utilizing an aluminum alloy conductor, it reduces weight by approximately 40% compared to equivalent copper cables (YJV22), significantly lowering transportation, handling, and support costs, thus offering greater economic advantages in project budgeting.
Dual Safety Protection: The ZC flame retardancy suppresses flame spread under fire conditions; the 22 steel tape armor structure provides robust crush and impact resistance, making it suitable for direct burial, cable trenches, and locations with risks of mechanical external forces.
Stable Electrical Performance: XLPE insulation combined with the 1.8/3kV medium-voltage design ensures high dielectric strength, a long-term allowable operating temperature of 90℃, and high current-carrying capacity.
Anti-Creep Reliability: The aluminum alloy conductor undergoes special alloying and annealing treatments, solving the historical issues of creep and loose connections associated with pure aluminum conductors, achieving connection reliability close to that of copper conductors.
