Spacers

Spacers

Precision-machined insulation components used to maintain uniform gaps between conductors and winding layers, ensuring proper oil circulation, electrical clearance, and mechanical stability within the transformer. Manufactured from UB-HD-3.1 and laminated board according to customer specifications, spacers offer excellent mechanical strength, dimensional accuracy, low moisture content, and consistent dielectric performance.

Strips

Strips

High-strength insulating strips manufactured from premium transformerboard, used for winding support, duct formation, and structural reinforcement. Precision-machined from premium cellulose-based insulation materials, strips provide high compressive strength, excellent dimensional stability, superior oil compatibility, and dependable electrical insulation characteristics.

Washers

Washers

Insulating washer rings designed to provide electrical insulation and mechanical support at fastening and clamping points. They help distribute pressure evenly while maintaining insulation integrity within the transformer assembly. Engineered for durability and insulation integrity, washers feature excellent dielectric properties, high mechanical strength, low shrinkage, and precise dimensional tolerances, ensuring consistent performance throughout the transformer's service life.
