Oil Filled Pad Mounted Transformer

Oil-filled pad-mounted transformers are specifically designed for residential, commercial, and industrial power distribution applications. These transformers offer a safe, efficient, and reliable solution for voltage step-down in urban and suburban areas. Encased in a tamper-resistant, weatherproof steel enclosure, they are ideal for ground-mounted installations, providing an aesthetically pleasing and secure alternative to overhead transformer systems. The oil insulation ensures optimal heat dissipation and electrical performance in varying environmental conditions.

Product Features and Specifications

These transformers are available in both single-phase and three-phase configurations, with power ratings ranging from 10 kVA to 5000 kVA. The oil-filled tank is designed to provide superior dielectric properties, preventing electrical breakdowns while also offering effective cooling through natural convection. The transformers are equipped with high-voltage bushings, load-break switches, and adjustable tap changers for voltage regulation. With their ability to withstand outdoor elements, these units offer long-term durability and low maintenance.

Transformer Structure and Design

The oil-filled pad-mounted transformer features a robust, steel enclosure designed to withstand harsh weather conditions and provide protection against unauthorized access. The interior of the transformer consists of a core made from high-grade silicon steel laminations, along with copper or aluminum windings. The insulating oil, typically mineral oil or environmentally friendly ester-based fluid, serves to cool and insulate the core and windings, ensuring efficient energy transfer. Additionally, the transformer is equipped with a conservator tank that accommodates oil expansion and contraction during temperature fluctuations.

Manufacturing and Production Process

Each oil-filled pad-mounted transformer is manufactured using advanced fabrication techniques to ensure precision and reliability. The core is carefully constructed to minimize core losses, and the windings are designed for optimal electrical conductivity and mechanical stability. The tank is welded and sealed to prevent oil leakage, and the transformer undergoes rigorous testing to ensure it meets performance standards, including dielectric strength tests and thermal tests. After assembly, the unit is filled with oil, sealed, and tested under load conditions to ensure safe operation before being shipped to the field.
