Product Overview
The single phase pole-mounted distribution transformer is designed for outdoor power distribution systems and is typically installed on utility poles. It is used to step down medium-voltage distribution line power to a lower voltage suitable for residential, commercial, and small industrial users.
With a compact pole-mounted structure, reliable insulation design, and natural cooling performance, this transformer is widely used in rural areas, suburban communities, remote power supply networks, and overhead distribution lines.
DHDL provides customized pole-mounted transformer solutions according to project voltage level, rated capacity, installation environment, protection requirements, and applicable grid standards.
