OIP or RIP Transformer Bushing: What Should Buyers Check?
Compare oil and dry-core construction, mounting, maintenance and model-specific IEC 60137 test evidence before choosing a transformer bushing.
Engineering knowledge
Compare construction, interfaces, materials and application requirements.
Compare oil and dry-core construction, mounting, maintenance and model-specific IEC 60137 test evidence before choosing a transformer bushing.
Check oil and gas interfaces, sealing, wall penetration, insulation level and the applicable test plan against equipment drawings.
Compare pressure, cantilever load, weight, creepage, flange interface and the model-specific tests under IEC 61462 or IEC 62155.
Review material, mechanical duty, insulation clearance, connection drawings and qualification tests for GIS insulating tubes and rods.
Define test voltage, waveform, specimen capacitance, measurement background, space and safety interfaces before requesting a test-system design.
Choose enclosure construction from geometry, material and batch needs, then agree weld, dimensional, pressure and leak-test acceptance.
Review pollution severity, hydrophobicity, tracking resistance and creepage; confirm material and test evidence for the specified insulator.
Identify voltage duty, field grading, moisture control, external insulation and altitude corrections in the project specification.
