PROCUREMENT DECISION CENTER

Distribution & Substation Procurement Center

Convert transformer datasheets, single-line diagrams and mixed equipment lists into a structured RFQ covering ratings, interfaces, protection, grounding, accessories and documentation.

From project question to an actionable RFQ

Define the system

Confirm voltage, application, environment and applicable standard.

Review compatibility

Match ratings, dimensions, interfaces, accessories and protection duties.

Build the supply scope

Connect the main equipment with fittings, installation materials, spares and documents.

Submit one RFQ

Upload the BOM or drawings for technical questions and quotation preparation.

System scope

Transformer specification

Confirm voltage ratio, capacity, frequency, vector group, impedance, tapping, cooling, insulation level, losses and accessories.

Primary switching

Define isolation, load switching, interruption, short-time withstand and interlocking duties.

Protection and measurement

Coordinate arresters, fuses, breakers, relays, CTs and VTs with the system fault level and protection philosophy.

Grounding system

Review soil and fault data, grounding transformer duty, neutral resistor interface, conductors, electrodes and connection hardware.

Auxiliary and installation scope

Include control power, cables, glands, lugs, cleats, support steel, labels, tools and commissioning spares.

Complete BOM review

Classify each line item, identify missing ratings and clarify what is supplied by the equipment manufacturer or site contractor.

What happens after submission?

Younxin reviews the supplied data as one system rather than isolated product names. The first response identifies missing or contradictory parameters, confirms the proposed review route and explains which drawings, datasheets, test reports, packing information or commercial details are required before a reliable quotation can be issued.
