Upgrading distribution networks in North America and Europe has further allowed automation-ready shell core units to find traction. Utility companies and EPC firms are investing in transformers suitable for integration with energy management systems, offering long-term supply contracts for established manufacturers.
A key emerging trend is increased adoption of solid insulated shell core transformers, which recorded the highest CAGR among insulation categories through 2024–2032. Oil-immersed cooling remains dominant in 2024 and 2025, especially for high-capacity designs in industrial segments, but dry-type units are gaining popularity in urban installations for safety and compactness. Design innovation has led to more compact medium-voltage shell core units tailored for emerging grid requirements in tight urban environments. This approach is positioning manufacturers to cater to both industrial and utility demands effectively.
Market growth has been constrained by raw material price volatility and limited manufacturing capacity in 2024 and 2025. Transformer makers have reported multi-year supply bottlenecks that could delay grid projects until at least late 2026. Initial high investment costs for shell core designs and competition from alternative core types have also limited adoption in cost-sensitive regions. Limited availability of high-grade electrical steel and insulation materials has raised per-unit costs and impacted vendor margins, adding further complexity to procurement strategies and contract negotiations.
