Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Dry Type Transformers. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This 220 kVA industrial isolation transformer is configured for three-phase step-down conversion from 380 V primary voltage to 70 V secondary voltage. It is presented for vacuum sintering and furnace power or heating systems that require a low-voltage, high-current supply.
The listed construction is a rectangular, core-type dry transformer with multi-winding architecture. Copper or aluminum winding options are available, and the stated insulation-class options for this configuration are H and F. The product listing reports working efficiency of at least 96%.
Vacuum impregnation is used to form the winding insulation layer. Available accessories include a temperature controller, cooling fans, and an enclosure case.
The specified operating environment includes ambient temperatures from -25°C to 55°C, relative humidity up to 95%, and installation altitude not exceeding 1,000 m without derating.
The installation location should not expose the transformer insulation to harmful chemical deposits, excessive dust, explosive media, or erosive media.
The incoming waveform should be approxima ss, enclosure protection, winding material, vector group, and accessory selection may depend on the approved order specification. Listed vector-group choices include Yd11, Dy11, Yy6, Yd5, and Dy1. The buyer should not assume that every option applies simultaneously.
Before procurement, confirm the required continuous and peak load profile, furnace duty cycle, primary and secondary tolerances, frequency, preferred winding conductor, vector group, impedance, temperature-rise limit, insulation class, enclosure rating, cooling arrangement, and accessory package.
Also request an approved technical drawing showing terminal arrangement, installation clearances, overall dimensions, weight, and mounting details. Confirm the exact standards and certification documents applicable to the ordered configuration, as well as routine and any project-specific test requirements.
Delivery schedule, packaging, inspection scope, and warranty terms should be recorded in the purchase contract.
