Diamond Power Infrastructure Limited has announced the successful commissioning of its 7th MV/EHV Power Cable Production Line at its advanced manufacturing facility in Vadodara, Gujarat. The newly commissioned line employs Continuous Catenary Vulcanisation (CCV) technology, a globally recognised method for manufacturing medium and extra-high voltage XLPE power cables. The investment of ₹55 crores has been funded entirely through internal accruals, with no external debt financing involved. The company further strengthened its integrated manufacturing capabilities in the MV and EHV Power Cable segment, catering to utilities, renewable energy projects, industrial infrastructure, metro rail, smart cities, data centres, and underground power distribution networks.
Capacity Addition Details
The commissioning of this line marks a significant operational milestone, adding 150 kms per month to the company's manufacturing capabilities. Diamond Power also disclosed that three additional MV/EHV Cable Lines are under various stages of installation and commissioning, expected to become operational before 31 March 2027.
The following table outlines the key parameters of the capacity addition:
| Parameter: | Details |
|---|---|
| Existing Capacity: | 900 kms per month |
| Present Capacity Utilisation: | 60% |
| Proposed Capacity Addition: | 150 kms per month |
| Commissioning Status: | Commissioned |
| Invested Amount: | ₹55 cr |
| Mode of Financing: | Internal accrual |
Strategic Focus and CCV Technology
Diamond Power has adopted a focused strategy to emerge as a leading player in the EHV and MV Power Cable industry by significantly expanding manufacturing capacities, strengthening technology capabilities, and increasing participation in high-value infrastructure and power transmission projects. The company believes India and global power infrastructure are entering a multi-decade investment cycle driven by several structural factors:
- Massive expansion in renewable energy generation
- Rapid growth in power transmission and distribution infrastructure
- Underground cabling in urban areas and smart grid investments
- Increasing industrial electrification
- Expansion of metro rail, airports, ports, and data centres
- Green energy corridor projects and growth in transmission voltages from 132 kV to 220 kV, 400 kV and beyond
CCV technology is regarded as one of the most advanced and globally preferred technologies for manufacturing MV and EHV XLPE Power Cables. The key advantages of this technology are summarised below:
| Advantage: | Description |
|---|---|
| Superior Insulation Quality: | Uniform cross-linking ensures improved dielectric strength and operational reliability |
| Lower Partial Discharge Levels: | Minimises insulation defects, contamination, and air voids for EHV performance |
| Enhanced Electrical Performance: | Superior electrical stress handling, higher voltage endurance, improved thermal stability |
| Improved Reliability: | Uniform curing and controlled parameters reduce failure rates in critical applications |
| Higher Voltage Grade Capability: | Enables production of advanced MV and EHV cables for demanding transmission requirements |
| Better Process Control: | Advanced automation improves manufacturing efficiency, consistency, and quality assurance |
| International Standards Compliance: | Facilitates production meeting stringent domestic and international utility specifications |
Industry Outlook
The MV and EHV Power Cable industry is entering a phase of sustained long-term growth both in India and globally. Global demand for HV and EHV cables is witnessing strong growth driven by renewable energy integration, underground transmission systems, offshore wind projects, and modernisation of ageing power grids. India is expected to remain one of the fastest growing power infrastructure markets globally due to rapid urbanisation, industrialisation, electrification, and renewable energy expansion.
Key industry trends include capacity utilisation across organised cable manufacturers remaining high, utilities and infrastructure developers increasingly preferring technologically advanced and quality-compliant suppliers, higher voltage underground transmission systems gaining adoption, and significant entry barriers in EHV cable manufacturing due to technology intensity, testing infrastructure, and execution capabilities.
Management Commentary
Commenting on the development, Ms. Nivedita Pandya, Vice President, Engineering and Projects, stated that the commissioning marks another important milestone in Diamond Power's growth journey. She highlighted that the company is making significant investments in advanced technologies and capacity expansion to strengthen its position in the high-growth MV and EHV Power Cable segment. She further noted that with three additional lines under commissioning before March 2027, Diamond Power is building substantial manufacturing capabilities to cater to rapidly growing demand from utilities, renewable energy projects, industrial infrastructure, and urban power transmission networks.
