Buyer questions answered before quotation
Why is bundle geometry required?
Sub-conductor number, spacing and diameter control spacer-damper selection, fittings, corona performance and string arrangements.
Can 220kV fittings be selected by conductor size alone?
No. Rated mechanical load, string configuration, attachment dimensions, corona requirements and environmental loading are also required.
What should the inspection plan include?
Approved drawings, material certificates, dimensional checks, galvanizing, mechanical/electrical tests and BOM-coded packing records.
