Product Description

Our full series of pole mounted distribution transformers are oil-immersed overhead power conversion units manufactured per global ANSI, IEEE and IEC standards, covering single-phase conventional, CSP self-protected and three-phase square models to fit worldwide grid requirements. With capacities ranging from 5kVA to 500kVA, these robust cylindrical & square tanks feature weather-resistant anti-corrosion coatings, standardized terminal layouts and heavy-duty pole mounting brackets for reliable outdoor overhead operation. Backed by over a decade of cross-continental export experience, we deliver tailored voltage schemes, full test certification support and cost-effective bulk supply solutions for power contractors, utility wholesalers and rural electrification projects globally.

Core Product Features

Conventional Single-Phase Cylindrical Pole Mounted Transformer

This ANSI/IEEE standard oil-filled transformer features a simple cylindrical tank with external mounting brackets for lightning arresters and fuses. It supports customizable voltage combinations from 5kVA to 167kVA for overhead residential power delivery. We have long-term export experience supplying bulk units to North America, Australia, Latin America and Southeast Asia rural grid contractors.

CSP Completely Self-Protected Single-Phase Pole Transformer

Integrated with internal primary fuses, secondary breakers and surge arresters, this all-in-one design eliminates extra external protective hardware. It cuts on-site installation time and delivers full overload, short-circuit and lightning damage protection. We specialize in North American market shipments with 10+ years of utility-grade supply experience for US and Canadian suburban distribution networks.

Three-Phase Square Pole Mounted Distribution Transformer

Compact square oil immersed unit engineered for 50Hz power grids with complete heat dissipation radiators and pole mounting lugs. Optimized for large-scale rural electrification and village overhead power supply projects. Our factory has stable export records serving power distributors across Southeast Asia, East Africa and Central Africa national grid renovation programs.
