Did you know2025
[single-source] In August 2024, Nexans (France, #1 global ACSR market share) announced a strategic collaboration with ZTT (Jiangsu Zhongtian Technology, China) to co-develop and manufacture high-capacity ACSR cables for HV and EHV grids. ZTT holds over 50% of the Chinese domestic submarine cable market and is the backbone supplier for China's "Belt and Road" undersea cable infrastructure projects. The partnership embeds Chinese cable manufacturing deeply into European and North American grid supply chains — a dual-use entanglement that CISA has flagged in grid security advisories, given ZTT's proximity to PLA-linked infrastructure contracts.
