Project Overview

The Taiwan Yung Tai Energy Storage Transformer Radiator Project supports transformer applications associated with energy storage systems, photovoltaic power stations and electromechanical engineering works in Taiwan, China. The project required radiator equipment compatible with high ambient temperatures, load fluctuations, harmonic influence and outdoor installation conditions.

Jiangsu Tengqi Electric Power Technology Co., Ltd. supplied 132 sets of PC1200-12/520 fin-type radiators for nine 4,500 kVA, 22.8 kV/0.69 kV transformers. TengQi Technology provided the radiator supply and manufacturing support around the transformer thermal-management requirement, with custom interface integration and a C3 corrosion-protection configuration developed for the project conditions.

Project Configuration

Application Requirements

Energy storage systems adjust power output in response to grid-frequency conditions and predefined operating profiles. In this application, the transformer supporting the storage system needs to accommodate changing electrical loads, harmonic effects and variations in ambient temperature, while also fitting the installation interfaces and sectional operating arrangement at site.

The radiator supply was therefore organized around several project-specific requirements:

• Interface compatibility with the 22.8 kV/0.69 kV transformer configuration;
• Structural coordination for load-impact and harmonic operating conditions;
• Consideration of radiator stability and durability in high-temperature outdoor environments;
• Surface protection for a C3 medium-corrosivity environment; and
• Consistency of product specification, coating configuration and installation interfaces across the batch supply.

Fin-Type Radiator Configuration

The project uses PC1200-12/520 fin-type radiators with custom interface structures to support integration with the transformer arrangement and the site’s sectional operating conditions. As part of the transformer cooling system, fin-type radiators increase the available heat-transfer area and assist the transformer in releasing heat generated during operation to the surrounding environment.

C3 Corrosion Protection Design

For outdoor installation, the radiator configuration adopts protection intended for a C3 medium-corrosivity environment. This type of application requires attention to the possible effects of rainwater, condensation, temperature differences and light industrial pollution on steel radiator surfaces, weld areas and edges.

The specified surface-protection system combines a 75 μm hot-dip galvanized layer with Taiwan-area #41 coating. The total dry-film thickness is configured at 195 μm according to the project documentation. The galvanized layer provides a protective foundation for the steel substrate, while the external coating adds environmental isolation and surface protection.

Actual corrosion-protection performance is also influenced by surface preparation, coating process control, transportation and installation handling, site conditions and subsequent maintenance.

Implementation Focus

Custom Interface Integration

Custom radiator interfaces were applied to accommodate the project’s installation and sectional operation requirements. Final interface dimensions, connection methods and installation details remain subject to the approved project design documents and mutually confirmed technical information.

Batch Manufacturing Consistency

The 132 radiators were organized under a unified model and project-specific technical configuration. TengQi Technology supports project coordination through its capabilities in fin-type radiator design, automated manufacturing, coating and quality verification, helping maintain alignment across product dimensions, surface protection and batch supply requirements.

Project Status and Relevance

According to the available project information, the equipment has been installed and is awaiting energization arrangements by the customer. Operating performance related to frequency detection, automatic power regulation and rapid charge-discharge response belongs to the overall energy storage system and should be evaluated against actual commissioning records, operating data and customer acceptance results after energization.

This project demonstrates an application approach for transformer fin-type radiator supply in energy storage, photovoltaic and related electromechanical engineering environments: matching radiator structure and interfaces to transformer conditions, applying project-specified C3 corrosion protection, and coordinating batch manufacturing around defined technical requirements. As a professional manufacturer of transformer radiators and thermal management solutions, TengQi Technology supports customers with product selection, design coordination, customized manufacturing and quality-verification services for oil-immersed transformer cooling applications.
