1000kVA Transformer | Dry Type, Oil-Immersed & Pad-Mounted Types
A 1000kVA transformer is essential for medium-scale power distribution systems, providing efficient and stable voltage conversion.
With advanced design and reliable insulation, it ensures long-term safety and performance across diverse applications.
As a professional transformer manufacturer, ZTelec Group supplies dry-type, oil-immersed, and pad-mounted (American box-type) transformers customized for global clients.
1. Classification of 1000kVA Transformers
1.1 Dry-Type Transformer
The dry-type 1000kVA transformer uses air for cooling and epoxy resin for insulation, ideal for indoor or fire-risk environments.
It’s known for excellent mechanical strength, moisture resistance, and low maintenance.
- Cooling method: AN (Air Natural) / AF (Air Forced)
- High insulation strength, low noise
- Eco-friendly and fire-resistant
- Maintenance-free and easy to install
Applications: Commercial buildings, hospitals, schools, tunnels, and data centers.

1.2 Oil-Immersed Transformer
The oil-immersed 1000kVA transformer uses insulating oil for both cooling and insulation.
It provides superior heat dissipation, high efficiency, and long service life, suitable for outdoor or heavy-load operation.
- Cooling method: ONAN / ONAF
- Excellent overload and thermal performance
- Stable operation with low noise
- Durable and easy to maintain
Applications: Power plants, substations, factories, and renewable energy systems.

1.3 Pad-Mounted (American Box-Type) Transformer
The pad-mounted transformer is an integrated distribution unit combining transformer, switch, and protection devices inside a sealed metal enclosure.
It’s compact, safe, and aesthetically suited for urban and residential distribution networks.
- Compact design and easy ground installation
- Fully sealed and safe for outdoor environments
- Ideal for underground power systems
Applications: Residential areas, shopping centers, commercial complexes, and industrial zones.
