TNNPI Oil-Immersed Step-up Transformers for Renewable Energy and Industrial Applications

As renewable energy projects, industrial facilities and power infrastructure continue to develop, reliable voltage transformation has become essential for efficient electrical power transmission and grid integration.

New Electric Power (TNNPI) focuses on customized transformer solutions, including oil-immersed step-up transformers designed for different power generation, distribution and industrial applications.

Customized Transformer Solutions for Multiple Applications

Oil-immersed step-up transformers are widely used to increase low-voltage AC power to medium or high voltage levels for transmission, collection and grid connection.

TNNPI's transformer solutions can be considered for:

  • Solar photovoltaic power plants and distributed PV systems

  • Battery energy storage systems (BESS)

  • Wind power generation and renewable energy projects

  • Industrial power stations and manufacturing facilities

  • Power generation and electrical infrastructure projects

Flexible Electrical Design and Configuration

Different projects require different transformer configurations. TNNPI can develop customized solutions according to project specifications and technical requirements.

Key design considerations include:

  • Rated capacity and voltage ratio

  • Three-phase configuration and vector group

  • Copper or aluminum winding options

  • ONAN or other applicable cooling configurations

  • Insulation level and temperature-rise requirements

  • Outdoor installation and protection requirements

Manufacturing and Quality Control

Transformer manufacturing involves electrical design review, material inspection, winding, core assembly, tank fabrication, oil processing, final assembly and applicable routine testing.

Testing requirements and inspection scope can be confirmed according to the applicable product standards and purchase specifications.
