Commissioning Meets Order Validation
Diamond Power Infrastructure's playbook in August is textbook capex strategy: invest in capacity, wait for validation, then scale. On August 20, the company commissioned a 1,500 MT per month copper wire drawing and cable manufacturing line at its Vadodara facility. Two days later, on August 22, it landed a ₹52.86 crore Letter of Intent from Aurionpro Solutions for specialized HT and LT electrical cables destined for a hyperscale data centre campus in Hyderabad. The timing is no accident—capex expansion into copper cables finds immediate commercial traction in one of India's hottest infrastructure bets.
The copper line isn't a bet on future demand; it's already fulfilling ₹53 crore of it before the quarter ends.
Copper Cable Line Commissioned
Diamond Power successfully commissioned a new copper wire drawing and cable manufacturing facility at Vadodara with an installed capacity of 1,500 MT per month. The line marks the company's formal entry into the copper cable segment, complementing its existing aluminium product portfolio and positioning it to serve high-power-intensity applications like data centres, renewable energy, and power plants.
Read:This capex expansion addresses a structural gap in Diamond Power's product mix. Copper cables command premium pricing and higher margins in the data-centre and hyperscale segments—traditionally an underpenetrated market for the company. The timing matters: data-centre cable demand in India is accelerating (backed by AI cloud buildouts and hyperscaler capex), and this production line now unlocks that TAM.
BSE Filing₹52.86 Cr Aurionpro Data-Centre Order
Aurionpro Solutions awarded Diamond Power a Letter of Intent for the supply of approximately 130 km of HT and LT electrical cables (including a significant copper conductor component) to a hyperscale data-centre campus under construction in Hyderabad. The order is valued at ₹52.86 crore inclusive of GST, with supplies scheduled on a staggered basis aligned to the construction timeline. This represents Diamond Power's first major entry into the hyperscale data-centre segment.
Read:This order validates both the capex and the market timing. Hyperscale data centres are a new TAM for Diamond Power, and a ₹53 crore LOI from Aurionpro (an established EPC player) signals institutional confidence. Staggered execution spreads delivery risk and provides visibility into ramp; the order book now includes material high-margin copper cable work. For a mid-cap cable maker, this is a material win.
BSE FilingThe Financials Say 'Keep Watching'
Diamond Power's Q1 FY27 results (reported August 13) set the stage for this capex play. Consolidated revenue hit ₹689.9 crore, up 128.6% year-over-year from ₹301.8 crore in Q1 FY26—reflecting the company's post-NCLT restart and ramp. Consolidated net profit came in at ₹58.4 crore, up 190.7% reported (or 145.5% adjusted for one-off items), demonstrating operating leverage as the company navigates its recovery arc. Operating margins held firm at 11.16% (flat sequentially, +92 bps YoY), while net margins expanded from 6.66% YoY to 8.38%—evidence of improving operational efficiency.
The copper line capex will now face the proof-of-concept test: does the Aurionpro order (and pipeline follow-on work) generate higher unit economics than the aluminium cable business? Copper cables typically command 5–10% price premiums and may carry margin upside, but execution risk centers on ramp-up speed and customer concentration. If Aurionpro becomes a beachhead for broader hyperscale adoption, the ROI on this capex is compelling. If the order remains isolated, questions about capacity utilization and fixed-cost absorption will resurface.
Q1 FY27 YoY growth: revenue +128.6%, PAT +190.7% (reported); +145.5% adjusted for one-off depreciation items.

The copper cable story is one of catalytic capex timing: the plant was commissioned, and a major order arrived within 48 hours. That's not luck—it's validation. Whether it's the opening move in a broader hyperscale cable playbook or a one-off win depends on the next two-to-three quarters. Revenue ramp, margin profile, and customer pipeline breadth are the readouts that will matter most for DIACABS investors.

Diamond Power's copper cable entry is a textbook example of capex validation: invest, announce, receive order proof. With a 1,500 MT/month line now operational and a ₹53 crore order already in hand, the company has de-risked the capacity bet. The data-centre segment represents a multi-year TAM expansion for Indian cable makers, and DIACABS' first-mover positioning (among mid-cap cable players) in copper hyperscale cables is material. Execution risk remains—margin profile, ramp velocity, and competitive pressure will determine whether this capex is a multi-quarter ROI story or a one-cycle win. Monitorables for the next two quarters are order burn, gross margin realization, and pipeline velocity. At current levels (₹353 near 52-week highs), the stock has priced in optimism; confirmation will come via revenue and margin proof in Q2 and beyond.
