Segmentation Analysis
By Installation
- Outdoor.
- Outdoor equipment generated USD 7,316 million and 62% of 2025 revenue, with a 5.8% CAGR through 2035.
- Pole-mounted, pad-mounted, and ground-mounted equipment remains the distribution-grid backbone across utility extensions and replacement programs.
- The segment benefits from rural electrification in India, Nigeria, and Brazil, as well as resilience-oriented replacement in North America and Europe.
- Its lower growth rate relative to indoor equipment reflects the mature installed base, not weak demand.
- Outdoor orders remain the most repeatable volume source for manufacturers with utility-grade product lines.
- Indoor.
- Indoor equipment generated USD 4,484 million and 38% of 2025 revenue, with a 7.6% CAGR through 2035.
- Commercial electrical rooms, underground substations, industrial sites, and data centers favor enclosed, space-constrained installations.
- Indoor demand is closely linked to dry-type cooling because fire safety and spill avoidance can outweigh the cost advantage of oil-filled designs.
- The growth implication is a richer mix of engineered, higher-value equipment rather than a simple migration of outdoor demand indoors.
By Cooling
- Oil immersed.
- Oil-immersed equipment generated USD 7,906 million and 67% of 2025 revenue, with a 5.7% CAGR through 2035.
- Liquid insulation and cooling support high power density, field-proven operation, and cost-effective deployment in outdoor utility networks.
