Jiangsu Tianrui Transformer

The homepage describes sealed 10 kV/0.4 kV and 20 kV/0.4 kV, 50 Hz distribution families. Its S11/S13/S20 and S11/S13 headings distinguish those two voltage routes. The separate 35 kV oil-immersed family belongs to a different voltage-class discussion. International buyers should state the required system voltage and frequency at the outset instead of assuming that a domestic catalogue configuration can be supplied unchanged.

Tianrui also publishes a high-overload 10 kV distribution category, describing short periods of heavy demand and rural holiday peaks as the application. That is a reason to discuss a measured load cycle. It is not a substitute for an agreed overload duration, starting temperature and recovery period. Include those operating conditions when requesting the proposed thermal duty.

The company introduction lists YB high/low-voltage prefabricated substations, ZGS combined transformers, charging-station transformer packages and electrical assemblies. The site separately shows switchgear assembly, sheet-metal processing and vacuum casting among its production-scene labels. These named activities help frame a factory discussion, but do not establish the scope of a particular contract.

For a complete package, separate the transformer requirements from medium-voltage switching, low-voltage distribution, protection, metering, enclosure and site interfaces. Ask which components Tianrui will supply, which are customer-supplied, and who is responsible for assembly testing. For a transformer-only order, confirm terminal arrangements and dimensional interfaces so that the unit can be integrated into the buyer’s own enclosure or substation.

The manufacturer’s contact page places the company in Taihan Industrial Park on Kunshan Road, Yitang Town, Pizhou. Its company introduction says it was established in 2016 in Xuzhou and began planning its Pizhou manufacturing site that year. For an inspection visit, request the areas relevant to the chosen construction: dry-type winding and casting differ from assembly of the complete switchgear package.

A Jiangsu public-procurement evaluation notice dated 27 January 2022 names Tianrui as the first-ranked candidate for dry-type transformers at the Longxi Bay south parcel phase-two development. This is a specific historical tender record. The evaluation notice alone does not establish delivery, commissioning or operational results; those require project acceptance records if a buyer needs a completed-project reference.
