配置

高性价比：铜导体 + PVC 绝缘的组合成本低于 XLPE 绝缘或低烟无卤电缆，适合预算有限、对环保无特殊要求的项目；
耐温稳定：90°C 工作温度比常规 70°C PVC 电缆更适配高温场景，减少因温度过高导致的绝缘失效风险；
布线灵活：单芯结构 + 多股绞合导体，弯曲性好，可在狭窄空间（如墙内穿管、设备内部间隙）轻松敷设；
维护便捷：绝缘层颜色可选（如红色、黄色、绿色、蓝色、黑色），便于电路识别（火线、零线区分），后期检修时可快速定位故障回路。

SAA认证

产品标准：AS/NZS 5000.1

铜丝+PVC 绝缘层

电气性能
- 电压等级：0.6/1kV（低压配电标准等级），可长期承受 600V 对地电压、1000V 线间电压，绝缘介损因数（20°C 时）≤0.08，电气绝缘可靠性高。
- 载流量：基于 “环境温度 40°C、自由空气敷设” 条件，不同截面载流量如下（参考值）：
  - 1.5mm²：约 24A（可带载 5.3kW 单相负载）；
  - 10mm²：约 65A（可带载 14.3kW 单相负载或 37kW 三相负载）；
  - 70mm²：约 185A（可带载 40.7kW 单相负载或 110kW 三相负载）；
  - 240mm²：约 330A（可带载 72.6kW 单相负载或 198kW 三相负载）；
- 短路耐受：短路时（1 秒内）可承受 20-100kA 短路电流（随截面增大而提升），绝缘层在短路高温下不易燃烧或熔化。
耐温与环境适应性
- 长期工作温度：-15°C 至 + 90°C（低温下 PVC 绝缘不脆裂，高温下不软化）；
- 耐化学性：耐受普通酸碱（如弱盐酸、弱氢氧化钠溶液）、油污（如机械油）的泼溅，不适用于强腐蚀环境（如化工厂浓酸碱区域）；
- 阻燃性：基础型 PVC 绝缘具备 “自熄性”（离开火源后 30 秒内熄灭），部分升级款可达到 GB/T 18380.1-2002 阻燃 B 级标准，适合人员密集场所。
机械性能
- 柔性：多股绞合导体使电缆弯曲半径较小（固定敷设时≥4 倍电缆外径，移动敷设时≥6 倍电缆外径），可在电缆桥架转角、墙内穿管等场景灵活布线；
- 耐磨性：绝缘层表面硬度≥邵氏 D65，可抵御常规敷设时的摩擦（如与穿线管内壁接触），不易破损。
