Product Description

pole-mounted distribution transformers are mounted above ground on poles. These transformers typically service urban and rural residential and commercial loads. Others are light industrial and commercial lighting applications.
ANSI pole-mounted transformers are available in a continuously self-protected (CSP) version from continuous overload and network protection from transformer faults.

Product scope

• Single-phase up to 167 kVA
• Three-phase up to 315 kVA
• Primary voltage up to 36 kV
• Secondary voltages up to 480 V
• Cooling type: ONAN
• Available fluids: mineral oil and ester fluids

What is a Distribution Transformer?

A distribution transformer, typically located near consumer load points, is a step-down transformer used in power systems. It decreases the high voltage to a safer, user-friendly level. Common voltage ratings range from 11 kV to 110 V. These transformers are designed for peak efficiency at 60-70% load utilization.

What is a Power Transformer?

A power transformer is mainly used to transmit high electric power at high voltage levels through power lines to the distribution centers. They generally have high MVA ratings. Power transformers are mainly used for increasing low voltage levels to high voltage levels for transmission, maximizing efficiency at or close to full loads.
