Diamond Power Infrastructure Secures ₹76.06 Crore Order for 66 kV EHV Underground Cables
Diamond Power Infrastructure Limited (DICABS) has secured a significant order worth approximately ₹76.06 crore, including GST, for the supply of 66 kV Extra High Voltage (EHV) underground power cables for a transmission project in Gujarat.
The company received the Letter of Acceptance (LoA) on September 3, 2026, from a domestic private-sector EPC contractor involved in power transmission projects.
The order is expected to strengthen Diamond Power’s position in the high-voltage power cable segment and adds to its growing exposure to India’s transmission and grid infrastructure expansion.
₹76.06 Crore Order for 293 Km of Cable
The order has a value of ₹76.06 crore including GST, while the value excluding GST is approximately ₹64.46 crore.
The contract covers approximately 2,92,985 metres, or 293 km, of underground power cable.
The specified product is:
- 38/66 kV (E)
- 1 core
- 630 sq. mm aluminium conductor
- XLPE insulated
- Copper wire screened
- Aluminium corrugated sheathed
- HDPE outer sheathed
- Underground power cable
The cables will be supplied on an FOR site basis for a 66 kV transmission project in Gujarat.
Deliveries to Start After Manufacturing Clearance
Diamond Power said deliveries will begin after manufacturing clearance.
The scheduled delivery rate is approximately 50 km per month, although the company intends to advance the schedule in line with project requirements.
At that rate, the approximately 293-km requirement represents several months of planned deliveries, providing near-term execution visibility.
The order is on a variable-price basis, meaning final realisation will be determined according to the applicable price-variation formula.
Why the Order Matters for Diamond Power
The latest contract is important because it is for 66 kV EHV underground cables, a technically demanding segment of the power-cable industry.
Diamond Power said its EHV manufacturing capabilities include technologies such as triple-extrusion CCV lines and corrugated metallic sheathing, along with the required testing capabilities.
The company is also expanding its medium-voltage and EHV manufacturing capacity as part of its ongoing capital expenditure programme.
India’s Transmission Expansion Creates Demand
India’s ongoing investment in electricity transmission and grid infrastructure is creating demand for high-voltage cables.
Underground cabling is particularly relevant in urban and industrial load centres, where conventional overhead transmission infrastructure can face land, right-of-way and other constraints.
Transmission requirements are also increasing as renewable-energy projects expand and electricity needs to be transported from generation centres to major consumption areas.
This creates a longer-term opportunity for manufacturers of high-voltage and EHV cables.
Growing Exposure to EHV and Infrastructure Projects
Diamond Power manufactures a range of power transmission products under the DICABS brand.
Its portfolio includes:
- LV, MV, HV and EHV power cables
- Control and instrumentation cables
- Fire-resistant and flame-retardant cables
- Solar DC cables
- EV charging cables
- Conductors
The company serves customers across sectors including power, infrastructure, oil and gas, renewable energy, real estate and data centres.
The latest order adds to its exposure to transmission infrastructure and reinforces the company’s focus on the EHV segment.
Investor Takeaway
For investors, the key positives from the announcement are the ₹76.06 crore order value, 293 km cable requirement and exposure to the EHV segment.
The order also provides an indication of continuing demand for high-voltage underground transmission infrastructure in Gujarat.
However, investors should also monitor execution, order inflows, capacity utilisation, working-capital requirements and the company’s ability to maintain margins as it scales up its EHV business.
The variable-price nature of the contract is another factor investors should keep in mind when assessing the final revenue and profitability contribution.
