Cylinders, Supports & Lead Insulation
Transformer Insulation Cylinders
Also known as: Pressboard Cylinders
Transformer insulation cylinders provide electrical separation, mechanical support and structural reinforcement around winding assemblies. Diameter, wall thickness, height, material, joints and dimensional tolerances are confirmed according to the transformer design.
Dimensions, materials, tolerances and testing requirements are confirmed according to customer drawings and order specifications.
