Pole Mounted Transformers

Pole-mounted distribution transformers are mounted above ground on poles. These transformers are manufactured to standard designs, primarily for power distribution companies. These transformers typically service urban and rural residential and commercial loads.

Pole Mounted Transformers are oil-immersed hermetically sealed types that are designed, manufactured and tested according to IEC 60076 and its equivalent standards. The tank is designed to accommodate the expansion of oil during loading through the use of corrugated steel sheets. The Primary bushings are provided on the bolted top cover, while Secondary bushings are on sidewall enclosed by air-insulated cable box. Both Primary and Secondary bushings can also be provided on top cover as per required specification.

The windings are generally made up of copper. However, Aluminum windings can also be offered. All the standard designs have been proven by type testing including impulse, temperature rise, sound level and short circuit tests.

Pole-mounted distribution transformers share the following features: 

• Compact design, Low-noise and light in weight.
• Economic and efficient to reduce network loss and working cost.
• High reliability in operation.
• Low-temperature rise and long service life.
• High short circuit and insulating strength.
• Overload capability in compliance with IEC 60354.
• Sealed construction to prevent moisture entry.
• Extended creepage HV bushings as standard execution.
• Utec’s standard proven surface treatment.
• Flexibility in designing transformers to meet customer requirements (Optimum cost)
• Competitive short delivery time.
