IEC Standard Step Down 10KV 11KV 400V Pole Top Distribution Electrical Service Transformer Single Phase Pole Mounted Transformer

Product Description

📋 Product Description

A pole-mounted (pole-top) transformer is a key distribution asset mounted on electrical poles, stepping down high-voltage grid power to customer-suitable levels. Manufactured in compliance with IEC 60076, ANSI, IEEE, CSA, and NEMA standards, it’s reliable for urban/rural residential areas, light commercial loads, railway electrification, and remote area electrification—ideal for global markets including Africa, Southeast Asia, and North America.

Designed for durability and ease of use, it features lifting lugs for hassle-free installation, high/low-voltage insulators (porcelain/fiberglass reinforced polyester) for safety, a self-venting resealing cover to prevent corrosion, and a step-lap joint wound core for efficiency and low noise. We offer flexible customizations: 5KVA–1000KVA capacity, up to 35KV voltage, copper/aluminum windings, mineral/biodegradable oil, and OEM options, plus matching accessories like mounting brackets and fuses.

As your one-stop partner, we provide 7-day fast delivery for standard models, custom order progress updates, a 5-year warranty, and 24/7 technical support—simplifying procurement and ensuring seamless grid integration worldwide.
