High-Quality Oil Immersed Transformer Insulation Components | Factory Direct

Introduction

As a premier China manufacturer of electrical insulation, we specialize in providing high-performance Oil Immersed Transformer Insulation Components for global power and distribution transformer OEMs. We understand that mid-sized transformer plants need a reliable partner who offers factory-direct pricing without the high overhead of local distributors. Our solutions are engineered to ensure maximum dielectric strength and thermal efficiency in liquid-filled environments.

Our Core Components

1. Oil Duct Strips & Spacers

Our precision-engineered oil duct strips (including zig-zag and corrugated types) create optimal cooling channels within transformer windings.

• Material: Electrical grade pressboard or Diamond Dotted Paper (DDP).

• Benefit: Enhanced oil circulation and heat dissipation.

2. Diamond Dotted Paper (DDP) & Film

Crucial for turn-to-turn insulation in oil-filled transformers.

• Feature: B-stage epoxy resin dots that bond during the drying process for superior mechanical stability.

3. Electrical Pressboard & Laminated Wood

Heavy-duty structural insulation for phase barriers, end rings, and support blocks.

• Compliance: Fully meets IEC 60641 and ASTM standards.

Why Choose Our Solutions?

• 20%-30% Cost Reduction: Buy directly from our production line in China and eliminate middleman markups.

• 100% Customization (OEM/ODM): We manufacture strictly according to your technical drawings—any thickness, width, or shape.
