I. Oil-immersed Transformer

Suitable for: Outdoor, harsh environments, limited budgets, and areas with low fire safety requirements.

Recommended Application Scenarios: Rural power grids, township and suburban power distribution; streetlights, new rural construction; industrial parks, factory power supply; mines, oil fields, field construction; coastal areas, high salt spray, rainy, and humid regions; ordinary outdoor pole-mounted and platform transformers; projects that are cost-sensitive and prioritize cost-effectiveness.

Key Features: Durable, inexpensive, and has good heat dissipation, but requires maintenance and carries risks of oil leakage and fire. II. Dry-type Epoxy Cast Transformer

Suitable for: High fire protection requirements, densely populated areas, indoor/underground locations, and places with strict environmental regulations.

Recommended application scenarios: Urban residential areas, city centers, densely populated commercial areas; shopping malls, supermarkets, office buildings, high-rise buildings; hospitals, schools, train stations, airports, subways; basements, high-rise building power distribution rooms; data centers, computer rooms, laboratories; stadiums, theaters, parks, scenic spots; projects with high fire protection, explosion protection, and environmental protection requirements; places where oil leakage and pollution are not allowed.

Key features: Fireproof and explosion-proof, oil-free and pollution-free, maintenance-free, high safety level, but more expensive.

III. Super Simple Comparison

Oil-immersed → Outdoor, rural areas, suburbs, poor environment, cost-effective.

Dry-type → Urban areas, densely populated areas, indoors, basements, strict fire protection requirements.
