Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of 11kv dry type transformer in China. If you're going to wholesale durable 11kv dry type transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
11kv dry-type transformers are widely used in medium voltage power distribution systems. 11kv transformers are usually used for urban power distribution, and 33kv are used for industrial high voltage. 11kV dry type transformers rely on fully sealed cast resin construction with zero oil inside. This key design choice makes them the go-to pick for any indoor space with strict fire safety codes, including high-rise commercial towers, underground city substations, server data centers and enclosed public building power rooms.

From Our Factory to Your Site
As a direct transformer manufacturer, we control the full production chain. Our facility runs under ISO 9001 and ISO 14001 management systems. Each finished 11kV dry transformer undergoes routine testing - insulation resistance, winding resistance, no-load loss, load loss, and impulse voltage testing - before it leaves the floor. We also maintain type-test records for our standard series, and we can arrange witnessed testing at third-party laboratories for project-specific requirements.
Lead times vary by rating and customization level. Standard catalog units typically ship within 24–26 weeks from drawing approval. For tender projects or large infrastructure contracts, we assign dedicated project engineers who track production milestones and coordinate logistics to your site.
