Strategic Focus and Technology
Diamond Power has adopted a focused strategy to strengthen its position in the EHV and MV Power Cable industry by expanding manufacturing capacities and upgrading technology. The company believes the sector is entering a multi-decade investment cycle driven by massive expansion in renewable energy generation, rapid growth in power transmission infrastructure, and increasing underground cabling in urban areas.
The CCV technology offers several advantages, including superior insulation quality, lower partial discharge levels, and enhanced electrical performance. This technology enables the production of advanced cables suitable for increasingly demanding transmission requirements and underground power infrastructure.
