Oil Type Distribution Transformer

Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of oil type distribution transformer in China. If you're going to wholesale durable oil type distribution transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.

This oil type distribution transformer is a highly practical and cost-effective power conversion solution engineered for global medium-voltage distribution networks. Built with standard industrial specifications, the unit steps down 11kV high primary voltage to 0.4kV low secondary voltage, perfectly matching conventional commercial, residential, industrial and municipal power distribution requirements worldwide. Equipped with natural oil cooling (ONAN) and a standard Dyn11 vector group configuration, this transformer delivers smoother power output, better current balance and stronger tolerance against unbalanced load operation compared with traditional transformer models.

One of the standout practical features of this 1000kVA oil immersed transformer is its flexible voltage regulation capability. It comes with a ±2×2.5% NLTC (No-Load Tap Changer) tapping range, allowing precise voltage adjustment during no-load operation. This functional design effectively solves common on-site problems such as grid voltage fluctuation and inconsistent input voltage in different regions, ensuring stable and compliant power output even in unstable power grid environments. It is an extremely user-friendly configuration for long-term outdoor and substation operation.
