Built Around Your Project, Not Just a Standard Model

Every project has its own voltage, grid standard, site condition, and installation plan. That’s why our substation transformer solutions are built around real project needs, with flexible options in voltage, insulation, phase configuration, loss target, and material selection. Whether you need an oil immersed transformer or oil filled transformer, we help you get a solution that fits the job from the start.

Transformer FAQs

In today’s tight transformer market, what is your typical lead time?

Lead time depends on rating, voltage class, IEC/ANSI requirements, and customization level. Typically, standard distribution and mid-size units are 12–20 weeks. If stock units are available, we can deliver in 2–6 weeks through a rapid retrofit program. Once we receive your key parameters, we’ll issue a practical delivery milestone plan (design → production → FAT → shipment).

We offer two mechanisms: a short quotation validity (market-linked) and project price/material locking for budget control on major orders. At contract stage, we clarify the cost structure and critical material strategy to reduce budget risk from commodity volatility.

Yes. We support both IEC 60076 and ANSI/IEEE C57 systems. To reduce acceptance risk, we confirm temperature rise, insulation/BIL, losses/efficiency, short-circuit withstand, noise, and test scope in the technical agreement, and provide a compliance matrix before FAT.

We perform FAT per IEC/IEEE standards, typically including ratio, winding resistance, insulation tests, applied/induced voltage tests, no-load/load losses, and impedance. Temperature rise, impulse, partial discharge, and noise tests are available upon request. We also offer remote FAT witnessing via live video, allowing you to view the procedure and readings in real time and align key points with our engineers.

We provide a verifiable “trust pack”: factory videos and key equipment list, production/testing process overview, reference projects (redacted if needed), management system certificates, and optional third-party audits (e.g., SGS/TÜV) upon request. We also support remote video factory audits and remote FAT witnessing to ensure transparent, traceable quality.

We apply export-grade packing and lashing plans and can install shock/tilt indicators to track abnormal impacts during transit. Oil-immersed and dry-type units use different moisture-proof and reinforcement methods (e.g., nitrogen/filled-oil options, vacuum moisture-proof packing—project-dependent). We also provide packing and lashing photo records for receiving inspection.
