Shandong Dachi Electric Co., Ltd.

Dachi's English contact page names Shandong Dachi Electric Co., Ltd., gives the Chengwu industrial-park address and separates product-sales and after-sales contact channels. The site's footer publishes the Chinese entity's unified social credit code, 91371700720758629B. Use that identifier and the Chinese name 山东达驰电气有限公司 when matching a quotation, invoice or technical agreement to the manufacturing entity.

The catalogue covers standalone transformers and larger equipment packages. At the quotation stage, identify which equipment is supplied by this legal entity and which interfaces belong to another contractor. A transformer order and a complete substation order need different scope schedules even when the same manufacturer can discuss both.

The published English product catalogue distinguishes 10 kV and 35 kV dry-type and oil-filled routes, then lists 110 kV, 220 kV and 500 kV oil-immersed categories. It also has separate entries for a mobile substation, split-winding equipment, traction transformers and inverter/energy-storage booster packages. These headings are useful starting points for an inquiry; they are not an all-combinations rating schedule.

Dachi's company introduction describes a wider portfolio envelope up to 750 kV, while the browsed English product grid has categories through 500 kV. Keep those two levels of information separate: ask for the actual proposed design and applicable reference instead of treating a company-wide statement as a guaranteed rating for every route.

A CQC bulletin hosted under its February 2025 publication directory names 山东达驰电气有限公司 as the manufacturer. On page 40, it lists the following groups. The recorded effective date is 21 February 2025, with a stated valid-until date of 20 February 2028. This is a reading of that dated bulletin; confirm the current certificate status and coverage when reviewing an offer.

The suffix /10 and listed capacity labels identify the published model groups. Do not fill in an unlisted intermediate model or transfer a certificate from one group to another. The same page does not publish numerical no-load or load losses for these groups, so this profile does not invent a kW comparison from the NX1 designation.

For an offer using one of these names, ask for the complete current certificate and the technical schedule for the exact configuration. Match the manufacturer, model, insulation class and scope before using the document in procurement approval. A named product document is more useful than a general certification badge covering the entire factory.

Dachi's own introduction describes a technical-standardisation function, a technology centre, a test station and a pilot plant. It also names a GEORG cross-cutting line, epoxy-resin vacuum casting and plasma cutting among its production equipment. These manufacturer statements give a practical starting point for a factory discussion: core preparation and liquid-filled assembly belong to a different manufacturing route from resin-cast windings.

For dry-type equipment, ask how the selected insulation system, casting process and temperature class are connected to the proposed design. For oil-filled equipment, ask for the core and winding assembly plan, insulation drying, tank and fluid preparation, and the production tests included in the purchase specification. Request records for the offered design and delivered units, rather than infer a test result from the presence of a machine or laboratory.

The introduction's capacity, patent and customer totals are not used here as order lead times or project guarantees. Delivery needs a quotation-specific production slot, drawing-approval schedule and test plan. A factory visit can then focus on the relevant process and documents for the selected equipment.

For a standalone transformer, send the rated kVA or MVA, primary and secondary voltages, frequency, vector group, taps, impedance, winding preference and installation conditions. Request guaranteed no-load and load losses with their reference conditions. State any witnessed tests and the document package needed at delivery.

For Dachi's mobile-substation or inverter/booster routes, add the single-line diagram and a responsibility schedule. Specify who supplies switchgear, protection, converter equipment, metering, auxiliary power and controls. Identify transport dimensions, access restrictions and commissioning interfaces before comparing a packaged price with a transformer-only offer.

If certificate coverage matters to the project, put the required model and current certificate verification on the same technical-review checklist. Keep the manufacturer identity, rating schedule, drawing revision and supporting documents together so a substituted configuration can be assessed before approval.
