Insulation Oil Duct Barrier for Transformer

Duct Barrier for Transformer: Engineered for Cooling, Insulation, and Structural Integrity

The insulation duct barrier for transformer is made by bonding transformer board sticks onto insulating paper or single-coated diamond dotted paper, which provides duct for the flow of the cooling oil in layers and strip winding in power transformers. It is designed to create stable and reliable circulation channels for transformer oil within distribution transformer coils, ensuring efficient cooling and robust electrical performance.

Product Characteristics of Transformer Oil Duct Barrier:

• Outstanding mechanical and electrical properties

• Exceptionally low shrinkage and compressibility

• Superior compatibility with liquid dielectrics (transformer oil)

Key Features & Specifications:

Insulation Class: A (105°C)

Base Material: 100% sulfate wood pulp

Mechanical & Electrical Strength: High

Dimensional Stability: Low moisture absorption, minimal shrinkage, and stable under heat and pressure

Primary Applications of Insulation Duct Barrier:

1. Power and Distribution Transformers

Heat Dissipation: Forms precisely defined channels for insulating oil to circulate between windings, effectively removing heat and maintaining optimal operating temperatures.

Electrical Insulation: Provides essential separation between high-voltage and low-voltage windings, capable of withstanding electric field stress as part of the overall insulation system.

Mechanical Support: Helps secure windings in place, offering resistance against displacement caused by electromagnetic forces or operational vibration.

2. Reactors and Other Electrical Equipment

Also employed in reactors and similar electrical systems, where it delivers reliable cooling and insulation, often under more demanding mechanical force conditions.
