Import 11kv Transformer Bushing Din 42531 — Buy in wholesale FOB from Supplier in China

Hunan Sun Electirc manufactures this DIN 42531-compliant transformer bushing for medium-voltage power distribution systems. The bushing is rated for 12.5kV and 250A, designed for both indoor (10Ni-250A) and outdoor (10Nf-250A) transformer installations. It meets the EN50180 standard alongside DIN 42531, which specifies dimensions, electrical clearances, and mechanical tolerances for porcelain or composite insulators in this voltage class.

The manufacturer's range extends from 12.5kV to 36kV, with outdoor variants available at 24kV (20NF-250A) and 36kV (30NF-250A), all at 250A continuous current. Typical insulation materials for this bushing class include high-grade porcelain or cycloaliphatic epoxy resin, with creepage distances suited to pollution degree III or IV environments per IEC 60137. The DIN 42531 flange mounting pattern is standardised across European and many Asian transformer OEMs, simplifying replacement and retrofit work.

Buyers for this product include transformer manufacturers, electrical utilities, and industrial maintenance teams sourcing replacement bushings for oil-filled or dry-type transformers. Orders can be placed for single indoor or outdoor types, and the supplier lists a full programme from low-voltage DIN 42539 bushings (1kV, 250A to 3150A) through to the medium-voltage units shown here. Confirm minimum order quantities, packaging (typically wooden crates with foam inserts), and lead times directly with Hunan Sun Electirc, as these are not specified in the listing.

Hunan Sun Electirc is based in Liling City, Hunan Province, China (postal code 412200). The company describes itself as a manufacturer of transformer bushings for both outdoor and indoor applications, with a product programme that spans low-voltage DIN 42539 bushings from 1kV/250A up to 1kV/3150A, and medium-voltage bushings compliant with EN 50180 and DIN 42531 from 12.5kV to 36kV. The listing does not provide information on factory size, workforce, export history, or specific client references.

The supplier's trust tier is classified as 'harbor' on the platform, and the recorded response rate is 0.00 with no average response time data available. This means buyers should expect to allow extra time for initial contact and should request documentation such as type-test certificates, material datasheets, and factory audit reports before committing to an order. No third-party certifications (ISO, IEC type-test, etc.) are claimed in the listing, so these should be verified directly.
