01The Story新闻事实

IndexBox projects sustained global growth in the THHN solar cable market through 2035, led by utility-scale photovoltaic expansion and higher-voltage systems. The market index is forecast to rise from 100 in 2025 to 185 by 2035, while copper-price volatility, specialized polymer supply and certification requirements remain key constraints.IndexBox预计，受公用事业级光伏扩张和更高电压系统推动，全球THHN太阳能电缆市场将持续增长至2035年。市场指数预计将从2025年的100升至2035年的185，而铜价波动、特种聚合物供应和认证要求仍是主要限制因素。

  • Utility-scale solar farms account for an estimated 55% of THHN solar cable demand, the largest end-use segment.公用事业级太阳能电站预计占THHN太阳能电缆需求的55%，是最大的终端应用领域。
  • Commercial and industrial solar installations account for an estimated 20% of demand.商业和工业太阳能装机预计占需求的20%。
  • The shift toward 1500V DC and higher systems increases cable lengths and insulation requirements.向1500伏直流及更高电压系统转变，将增加电缆长度和绝缘要求。
  • The market index is projected to reach 185 in 2035, with 2025 set as the base year at 100.以2025年为100的基准，市场指数预计将在2035年达到185。
  • Copper is the dominant variable cost, while UL and IEC certification requirements shape competition and market entry.铜是主要的可变成本，而UL和IEC认证要求影响竞争格局和市场进入。

Solar capacity growth supports long-term cable demand, but profitability remains exposed to copper costs, supply constraints and certification requirements.太阳能装机增长支撑电缆需求的长期扩张，但盈利能力仍容易受到铜成本、供应限制和认证要求的影响。

023 Dimensions维度分析

Cause因果关系

Utility-scale solar is the main demand engine公用事业级太阳能是主要需求引擎

Large solar farms require extensive DC-side wiring, and higher-voltage designs increase cable requirements per megawatt. The sector is expected to remain the dominant demand source through 2035.大型太阳能电站需要大量直流侧布线，而更高电压设计会提高每兆瓦的电缆需求。预计到2035年，该领域仍将是主要需求来源。

Utility-scale solar share公用事业级太阳能占比

Estimated share预计占比55 %

Estimated share预计占比20 %

  • Utility-scale projects typically range from 50 MW to several gigawatts and connect large numbers of panels to inverters and combiners.公用事业级项目通常规模从50兆瓦到数吉瓦不等，需要将大量组件连接至逆变器和汇流箱。
  • Solar-plus-storage projects may require additional cabling.太阳能加储能项目可能需要额外布线。
Consequence影响推演

Higher voltage raises cable intensity更高电压提高电缆使用强度

The adoption of 1500V DC systems and above is linked to longer cable runs and more robust insulation. This increases cable consumption per megawatt while adding performance and safety requirements.采用1500伏直流及更高电压系统，与更长的电缆线路和更坚固的绝缘层相关。这会提高每兆瓦的电缆消耗，同时增加性能和安全要求。
