75 kVA Single Phase Pad Mounted Transformer

The ZGDL-H-75/14.4/0.24(0.12) is a 75 kVA single-phase pad-mounted transformer model crafted by Daelim Transformer. These transformers are commonly integrated into power distribution systems, facilitating the conversion of high-voltage power from transmission lines into lower voltages suitable for various applications, including residential, commercial, and industrial settings. They are instrumental in supplying power for lighting, electrical appliances, machinery, and various facilities in a wide array of locations, such as homes, offices, factories, retail outlets, hotels, and healthcare facilities. These transformers are typically mounted above ground on specially designed pads or platforms, hence the name "pad-mounted."

The 75 kVA single-phase pad-mounted transformer employs the ONAN cooling method and uses mineral oil as the insulating liquid, characterized by a fire point equal to or less than 300°C. Polarity is additive for the 75 kVA transformer, and the core is effectively grounded. These 75 kVA transformers feature two internally connected high-voltage bushing wells, identified as H1A and H1B, fitted with removable bolts. These wells can be connected to the distribution system via deadbreak elbows, designed for dead-front operation, and strictly adhere to the dimensional and electrical requirements outlined in IEEE 386. Each high-voltage bushing well is thoughtfully furnished with a protective cap. The low-voltage bushings are equipped with three stud-type bushings with copper plating and 7-hole terminals. Every unit 75 kVA transformer is equipped with two 2-position oil-immersed load-break switches, specially designed to operate within a temperature range spanning from -40°C to 120°C, employing a hot-stick mechanism.

During the 75 kVA transformer assembly process, Daelim Transformer workers conduct more than three rounds of testing, including tests for current, voltage, transformation ratio, leakage, and other parameters, on each transformer. This rigorous testing is performed to ensure the electrical and mechanical integrity of the transformer. Subsequently, each assembled transformer undergoes the routine tests mentioned earlier. After successfully completing these final routine tests, Daelim Transformer promptly generates a comprehensive professional test report, which is then submitted to the buyer for review. The report documents energy efficiency and test results, including those specified in Items (c), (d), and (e), as per CAN/CSA-C802.1 standards. It is signed by a professional engineer or another authorized individual. Only when the transformer's performance and safety indicators meet or exceed the required standards will it be ready for shipment to the buyer.
