Performances
Electrical Performance: High insulation strength and low dielectric loss after oil immersion; compatible with transformer oil without impurity precipitation, low water absorption and low partial discharge tendency.
Mechanical Performance: The integrated structure resists compression and short-circuit impact to prevent oil duct collapse and deformation. The flexible base paper fits winding of all coil types with no delamination or glue separation.
Thermal & Processing Performance: Stable long-term thermal aging performance matching the full service life of transformers; easy drying and degassing for vacuum oil impregnation, convenient to cut and process.
Technical Specifications
The product can be manufactured in various forms to suit different winding configurations, such as rectangular strips, T-strips, and dovetail strips.
Applications
Core Applications: Inside oil-immersed power transformers and distribution transformers, used to support winding coils and construct cooling oil ducts.
Specific Installation Positions:
- Between winding layers – forms axial or radial oil ducts to ensure heat dissipation.
- Between coils and the core, or outside the coils – tightens the coils to enhance short-circuit withstand capability.
