Transformer Procurement Checklist

PRACTICAL GUIDE

Project context

Technical and commercial checks for power-transformer procurement. For projects in Afghanistan, early definition of operating conditions, site access, utilities, local skills and maintenance capability helps prevent avoidable procurement changes.

Planning and specification

Buyers should confirm vector group, impedance, losses, cooling class, tap range, accessories, testing and transport limitations. Requirements should be recorded in a clear datasheet and linked to applicable standards, inspection stages, documentation, delivery conditions and acceptance criteria.

Typical equipment and supply scope

Transformers, bushings, radiators, fans, conservators, OLTC spares, protection devices and oil-test kits. The final package should also consider commissioning materials, recommended spares, special tools, training, warranty support and export packing suitable for the complete transport route.

Procurement approach

Comparable bids require one consistent technical scope. Supplier deviations should be listed separately, while drawings, certificates, test reports, country of origin, delivery schedule and after-sales support are evaluated before award.
