Shenyang Fulin Special Transformer

The company’s main introduction describes a comprehensive range at 110 kV and below, including oil-immersed power, furnace and rectifier transformers. It separately describes distribution equipment at 35 kV and below. The homepage also carries a 132 kV oil-immersed product heading. For a project at that higher voltage, request the specific proposed design and its technical documentation rather than applying the catalogue heading to the whole company range.

For a grid or station transformer, define the voltage ratio, rating, tap arrangement and installation duty. For a furnace or rectifier transformer, describe the connected process and operating cycle as well. These special-purpose families cannot be evaluated solely by matching a kVA number to a conventional power transformer. Agree the proposed electrical duty and the relevant acceptance tests before comparing offers.

Fulin’s introduction names wind-generation and photovoltaic combined substations at 35 kV and below. It also lists epoxy-cast, impregnated and special dry-type equipment within that voltage class, together with switchgear and distribution assemblies. A renewable-energy inquiry should therefore identify whether the requirement is for the transformer itself or the complete substation package.

For the package, define the switching, protection, control and enclosure boundaries. For dry-type equipment, specify winding construction, cooling and environmental conditions. The catalogue’s cast and impregnated labels identify different manufacturing routes; they do not establish the enclosure or insulation system for every offer. Losses, impedance and winding material should be recorded for the exact proposed configuration on the quotation schedule.

Fulin’s historical account describes a technical-development function using computer-aided design and later information-management tools. It also includes dated descriptions of production and inspection equipment. These explain the company’s published development history, but equipment counts from an earlier year should not be treated as an inventory for a current factory visit.

Set the inspection agenda around the order: winding and insulation processing for the selected construction, core and assembly work, and the test facilities needed for the proposed voltage class. Ask for the current inspection plan and model-related documents. This gives a buyer a more concrete basis for a visit than a general company-size or historical quality-award statement.
