Diamond Power Infrastructure Limited will add a new Catenary Continuous Vulcanisation (CCV) line for cables up to 132 kV at its Vadodara plant. The company announced the expansion on October 22, 2026, citing growing demand for high-voltage and extra-high-voltage underground cables from state utilities and renewable energy parks.
The project requires an investment of ₹25 crore, including floor extension costs. Diamond Power stated that the entire expenditure will be funded through internal accruals. The machinery is scheduled for delivery by August 2027, with commissioning targeted for December 31, 2027.
Capacity and Investment Details
The new line will enhance the company's existing EHV cable capacity. Currently, Diamond Power operates six CCV lines with an estimated capacity of ~2,000 km per annum. The addition of this seventh line aims to address specific customer requests for larger volumes on shorter timelines.
| Particulars | Details |
|---|---|
| Existing capacity | 6 CCV lines; EHV cable capacity ~2,000 km p.a. |
| Existing utilisation | 60% |
| Proposed addition | One CCV line, up to 132 kV p.a. |
| Investment required | ₹25 crore |
| Mode of financing | Internal accruals |
| Commissioning target | December 31, 2027 |
Strategic Rationale
The expansion is designed to meet the rising demand for HV/EHV underground cables. Kavish Shah, Vice President at Diamond Power Infrastructure, noted that the new line strengthens the company's position as a leading manufacturer of MV and EHV cables. The facility will leverage existing in-house resources, including aluminium rod mills, compounding units, and NABL-accredited high-voltage test laboratories rated up to 765 kV.
What the Numbers Show
The decision to invest in additional capacity despite current utilisation standing at 60% suggests confidence in near-term order inflows rather than immediate volume pressure. The company explicitly links this capital expenditure to an "EHV order book" that is growing steadily, indicating that the expansion is demand-led rather than speculative. Funding the project entirely through internal accruals avoids diluting equity or increasing debt, preserving balance sheet flexibility during the construction phase.
