Efficiency Oil Immersed Hermetically Sealed Three Phase Pole Mounted Distribution Transformer

The S9 series transformers are basic oil-immersed three-phase transformers with a rated capacity of 30KVA to 2500KVA, suitable for power systems operating at 6KV to 11KV. The design can be customized according to customer needs. S9 transformers offer low manufacturing costs, good stability, and high efficiency, making it an indispensable part of the power transmission process. They are widely used in transmission lines and substations and can be adapted for various applications requiring transformer adjustments.

Tianya offers high-performance pole mounted distribution transformers, available in both single-phase and three-phase configurations. These transformers are designed to shorten low-voltage distribution lines, reduce line losses, and enhance power supply quality. Featuring a high-efficiency, energy-saving core structure, they are compact in size, require minimal infrastructure investment, and significantly cut low-voltage line losses by over 60%.

Built with a fully sealed structure, the transformers deliver strong overload capacity, high operational reliability, and easy maintenance. They are ideal for rural power grids, remote mountainous areas, dispersed villages, agricultural applications, and general lighting and power use. Additionally, they support energy-saving upgrades in railway and urban power systems.

Engineered with advanced technology and made from premium materials and components, our pole mounted distribution transformers ensure long service life and dependable performance.

· Oil Tank: Corrugated oil tanks with a fully sealed structure, where corrugated panels provide heat dissipation and expansion functions, automatically adjusting with temperature, load size, and oil level changes. This design ensures complete isolation of transformer oil from air and eliminates maintenance needs throughout the transformer's life.

· Excellent Safety performance: the pressure release valve is installed on the fully sealed transformer, which expands the application range of the pressure release valve, and increases the safety protection of the transformer.

· Tap-changer: it is adopting double-sealed vertical switch, which improves the sealing performance of the switch.

· Fastening: select the new type of lock nut to ensure that the transformer body is tight and not loose during transportation.
