Common selection questions and document paths

Bushings

Compare oil and dry-core construction, mounting, maintenance and model-specific IEC 60137 test evidence before choosing a transformer bushing.

Hollow Insulators

Compare pressure, cantilever load, weight, creepage, flange interface and the model-specific tests under IEC 61462 or IEC 62155.

GIS Cylinders & Rods

Review material, mechanical duty, insulation clearance, connection drawings and qualification tests for GIS insulating tubes and rods.
