Gooseneck Transformer Radiator
Key Advantages:
Flexible Installation in Limited Space: The curved header design avoids interference with transformer accessories and reduces the need to redesign the tank.
Customized for Accurate Assembly: Center distances, gooseneck height, panel width, flanges and mounting interfaces are manufactured according to approved drawings.
Lower Leakage and Rework Risk: Every radiator is air-pressure tested at 150 kPa for 20 minutes before delivery.
Production starts from 8 days, depending on drawings and quantity.
Nantong Zhihe Electric Co., Ltd. is a leading manufacturer of transformer radiators.Zhihe focuses on the product itself and has built a professional, stable, and experienced technical R&D team to ensure quick and efficient solutions for customers.
Gooseneck transformer radiators consist of two sets of radiator fins of different lengths connected by curved oil collection pipes.Compared to conventional radiators, gooseneck transformer radiators are highly adaptable. When installation space is limited or to avoid special devices on the casing, gooseneck transformer radiators cleverly solve these problems.
Advantages of Gooseneck Transformer Radiators
Avoid Costly Tank Redesign
The curved header design helps bypass valves, pipes and other tank-mounted accessories in space-constrained layouts.
Accurate Drawing-Based Fit
Long and short center distances, offset height, flanges and mounting interfaces are manufactured according to approved drawings.
Lower Leakage and Installation Risk
Every radiator is tested at 150 kPa for 20 minutes, helping reduce leakage, assembly rework and project delays.
Why Choose Our Gooseneck Transformer Radiator?
Anti-Air Lock & Superior Heat Dissipation: The arched gooseneck header design optimizes natural thermo-siphon oil flow and prevents gas bubbles from accumulating, maximizing thermal efficiency.
Flexible Layout Solutions: Engineered for complex tank designs where traditional straight-header transformer radiator types cannot fit due to clearance or accessory limitations.
C3–C5 Anti-Corrosion Protection: Premium coating systems compliant with ISO 12944 (C3, C4, C5) or Hot-Dip Galvanizing (HDG) engineered for urban, industrial, coastal, and high-salinity outdoor environments.
100% Pneumatic & Hydraulic Leak Tested: Every transformer radiator undergoes underwater pressure testing at 150KPa for 20 minutes before dispatch to ensure zero leakage.
