PC3000-32/520 Detachable Panel Radiator

Composite Anti-Corrosion Cooling Component for Large Oil-Immersed Power Transformers

The TengQi Technology (TQT) PC3000-32/520 is a detachable panel radiator for high-voltage transformers, designed primarily for the cooling systems of 220kV and 500kV large-capacity oil-immersed power transformers. Featuring a panel-radiator structure and a composite hot-dip galvanizing plus flow-coating surface treatment, it provides a clear selection option for projects requiring both effective heat dissipation area and enhanced environmental corrosion protection.

Primary Application

220kV and 500kV Oil-Immersed Power Transformers

Suitable for coastal locations, chemical industrial zones, acid-rain-prone areas, overseas projects, and other environments with demanding external surface durability requirements.

Why High-Voltage Transformer Radiators Need Corrosion Protection

Heat generated during operation of an oil-immersed power transformer must be transferred through its cooling system. In high-capacity, high-voltage projects, radiators must be matched to thermal operating conditions while their external surfaces may be exposed long term to heat and humidity, salt spray, industrial pollutants, or acidic precipitation. Heat dissipation performance, installation conditions, and surface protection design should therefore be considered together in project technical specifications.

Coastal Salt Spray and Humidity

Hot, humid conditions and salt spray at coastal substations increase the importance of external metal surface protection.

Industrial Contaminants

Chemical and industrial zones may contain complex corrosive gases and contaminants, requiring product selection based on site environmental assessment.

Export Transport and Operating Conditions

Overseas projects require consideration of local climate, transport methods, installation conditions, and applicable technical standards.

Hot-Dip Galvanizing Plus Flow Coating: How the Composite Surface Treatment Works

The PC3000-32/520 uses a dual-protection system combining hot-dip galvanizing and flow coating. The hot-dip galvanized layer provides primary corrosion protection, while the flow-coating layer forms an additional external barrier. Together, these treatments address radiator surface protection requirements in demanding environments. Actual corrosion resistance also depends on substrate condition, coating quality, transportation, installation, and site conditions.

Layer One

Hot-Dip Galvanized Base Protection

A 60 μm hot-dip galvanized layer helps reduce the risk of corrosive media directly reaching the metal substrate, providing primary external surface protection.

Layer Two

Flow-Coated Outer Barrier

A 260 μm flow-coating layer is applied over the galvanized surface to help block moisture, salt spray, and other external corrosive media.

Combined Value

Complementary Dual-Layer Protection

The composite treatment with a total coating thickness of 320 μm provides an additional foundation for surface protection if localized coating damage occurs.

Applicable Applications and Project Use

This corrosion-resistant transformer radiator is suitable for projects requiring cooling components for large oil-immersed power transformers and having specific environmental durability requirements for external surfaces. Product selection can be verified based on thermal calculations, oil circuit design, connection dimensions, installation space, and project specifications.

Coastal Hub Substations

For salt spray and hot, humid environmental conditions, the composite anti-corrosion surface treatment can be included in the evaluation of cooling equipment for large power transformers.

Chemical Industrial Zone Substations

For areas potentially exposed to corrosive gases and industrial pollution, product suitability should be confirmed against environmental assessments and project technical specifications.

Acid-Rain-Prone Areas

In regions with stringent external corrosion protection requirements, the PC3000-32/520 can be evaluated as a component option for oil-immersed power transformer cooling systems.

Overseas Power Projects

Product selection and supply conditions can be confirmed on a project basis according to destination climate, corrosivity category, transport conditions, and local technical standards.
