Features and construction
The sealed cylindrical steel tank carries two high-voltage porcelain bushings on the cover and low-voltage terminals on the side, with mounting brackets for direct attachment to a distribution pole. The oil-filled hermetic design protects the windings from moisture and provides efficient cooling, giving dependable single-phase distribution with minimal maintenance.
Typical applications
Overhead distribution lines for residential neighborhoods, rural electrification, farms, streets and light-commercial loads where single-phase pole-mounted step-down is required.
Customisation options
Capacity, HV/LV voltage, winding material, bushing type and mounting hardware can be customized to local grid standards (e.g. ANSI/IEC).

Frequently asked questions
What is the rated capacity of the Single-Phase 25kVA & 50kVA Pole-Mounted Distribution Transformer?
The standard configuration is rated 25 kVA & 50 kVA at 50 / 60 Hz. Other ratings in the same family can be built to order — tell us the load and we will confirm the nearest standard rating.
What voltage ratio is available?
The standard unit is 13.2 kV (or custom) input to 120-240 / 240-480 / 347 / 600 V (or custom) output. Voltage ratio, tapping range and vector group can be adjusted to your network; 50 Hz and 60 Hz designs are available.
Which standards and certifications apply?
The product is designed to IEC / GB. MARS operates an ISO 9001 / 14001 / 45001 certified factory and holds CE (ECM), UDEM, EAC and CQC approvals; every unit is routine-tested before dispatch and type or witnessed tests can be arranged.
Can this product be customised?
Capacity, HV/LV voltage, winding material, bushing type and mounting hardware can be customized to local grid standards (e.g. ANSI/IEC).
What is the lead time and how is it shipped?
Packed in wooden case. Typical lead time is 25–45 days after drawing approval for distribution equipment and 60–90 days for power transformers and containerised systems. Shipment is by sea from Shanghai on EXW, FOB, CIF or DAP terms with a full document pack.
