As a professional manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our reliable 250kVA Pole Mount Transformer. Engineered for durability and efficiency, this transformer is a cornerstone for stable power distribution in utility and industrial applications. We combine rigorous manufacturing processes with quality materials to deliver a product that meets the demanding requirements of global markets, supported by comprehensive documentation and assurance.

Core Features & Technical Advantages:

Robust Construction: Built with high-grade silicon steel laminations and copper/aluminum windings to ensure low losses, high efficiency, and long-term operational stability.
Optimized Thermal Management: Utilizes ONAN (Oil Natural Air Natural) cooling, effectively dissipating heat under continuous load, extending insulation life and reliability.
Pole-Mounted Design: Specifically engineered for secure installation on utility poles, saving ground space and simplifying grid expansion in rural, suburban, and industrial areas.
Customizable Specifications: Primary and secondary voltage ratings can be tailored to match specific regional grid standards (e.g., 11kV/400V, 33kV/415V).
Comprehensive Quality Assurance: Each unit undergoes stringent factory tests, including ratio, polarity, impedance, and insulation resistance tests. A detailed Mill Test Report (MTR) is provided, certifying material composition and performance data.
Warranty Protection: Supplied with a manufacturer's warranty, offering peace of mind and protection against manufacturing defects.

Key Technical Specifications:

Parameter	Specification
Rated Capacity	250 kVA
Frequency	50 Hz / 60 Hz (Optional)
Cooling Type	ONAN (Oil Natural Air Natural)
Insulation Class	Class A or higher
Vector Group	Dyn11, Yyn0, or as required
