DDP Oil Duct Strips - China Manufacturers, Suppliers, Factory
Advanced Cooling Solutions for Liquid-Filled Transformers: Optimize Thermal Performance
Introduction
Effective thermal management is the key to extending the lifespan of any power or distribution transformer. As a specialized manufacturer, we provide Liquid-Filled Transformer Cooling Solutions that focus on optimizing internal oil flow. Our precision-engineered components create the essential pathways required for efficient heat dissipation within the windings, ensuring your equipment runs cooler and lasts longer.
Core Cooling Components
1. High-Efficiency Oil Duct Strips The backbone of any liquid-cooled system. Our strips are designed to maintain consistent gap intervals between winding layers, significantly reducing hotspots.
-
Material: High-density electrical pressboard / Diamond Dotted Paper (DDP).
-
Function: Creates stable, unobstructed channels for natural or forced oil convection.
2. Precision Winding Spacers & Blocks Strategically placed to ensure mechanical stability while maximizing the surface area exposed to the cooling oil.
-
Customization: Tailored to your specific winding geometry to minimize flow resistance.
Value Proposition
-
Maximize Thermal Efficiency: Our designs are focused on reducing the "oil flow stagnancy" that causes premature insulation failure.
-
Cost-Effective Manufacturing: Buy directly from our China factory to get high-performance cooling components at a fraction of the cost of Tier-1 suppliers.
-
Durable in Hot Oil: All materials are rigorously tested for long-term compatibility with mineral and ester oils (FR3), ensuring no degradation at high operating temperatures.
-
Rapid Prototyping for Engineers: We support R&D and mid-sized production runs with fast turnarounds on custom cooling duct designs.

FAQ
Q: How do oil duct strips improve liquid-filled transformer cooling?
A: They create uniform "cooling chimneys" between winding disks. This allows the hot oil to rise and circulate more effectively to the radiators, preventing localized overheating.
Q: Can you manufacture cooling spacers for high-viscosity bio-oils (FR3)?
A: Yes. We can adjust the thickness and surface finish of our spacers to optimize flow even for thicker natural ester fluids used in modern green transformers.
