A 10 Kv 500kva Pole Mounted Distribution Transformer is a three-phase, oil-immersed, outdoor type transformer installed directly on utility poles for stepping down 10 kV medium voltage to 400V low voltage (line-to-line) for residential, commercial, and light industrial power distribution. It features compact design, full-sealed tank, low loss, low noise, and minimal maintenance, compliant with IEC 60076 and GB/T 1094 standards.
Built for durability and efficiency, 10kV 500kVA pole mounted distribution transformer adopts a compact, space-saving design that eliminates the need for dedicated substations, significantly reducing civil construction and installation costs. The fully sealed corrugated tank structure prevents oil leakage and moisture ingress, ensuring maintenance free operation and a service life of over 20 years under normal conditions.
Engineered with S11 grade low loss silicon steel core and high conductivity copper windings,10kV 500kVA pole mounted distribution transformer can achieve low no-load and load losses, which is conducive to reduce operational energy consumption and long term utility costs. Its noise level is controlled below 55 dB, making it environmentally friendly for residential areas.

10 kV 500 kVA pole mounted distribution transformer is designed for direct installation on concrete or steel poles , saving the need for ground space. Its optimized compact configuration and reduced weight simplify transportation, and on-site installation, significantly cutting civil engineering and construction costs for distribution projects. The design is engineered to withstand the mechanical stresses of pole mounting, ensuring long-term safety even under wind and vibration loads.
Equipped with S11 series low loss core technology,10 kV 500 kVA pole mounted distribution transformer delivers 10–20% lower no-load and load losses compared to conventional models. By utilizing cold rolled grain oriented silicon steel cores and precision wound copper windings, it minimizes energy waste during both full and partial load operation. This results in reduced operational costs, lower carbon emissions, and improved overall efficiency .
The fully sealed, welded tank design prevents oil leakage, moisture ingress, and contamination from dust or debris. These eliminates the need forroutinemaintenance, ensuring consistent performance and a service life of over 20 years under normal operating conditions. The corrugated storage tank also serves as an integrated cooling system, which can efficiently dissipate heat and provide a completely sealed environment for the transformer oil.
Built with high short-circuit mechanical strength, the 10 kV 500 kVA pole mounted distribution transformer is designed to withstand fault currents without deformation or failure. Its low-noise design, controlled below 55 dB, ensures minimal environmental impact in residential and urban areas. Excellent thermal stability and a wide operating temperature range (-25°C to +40°C) make it suitable for diverse outdoor conditions, including high humidity, heavy rain, and extreme temperature fluctuations.
