Product descriptions from the supplier
Description

Description:

This is a single-phase oil-immersed pad-mounted transformer certified by UL, specially designed for outdoor installation. It complies with UL 1561 (Dry-Type Transformer) or UL 1562 (Oil-Immersed Transformer) standards, suitable for capacity ranges of 15-500kVA, with voltage classes covering 7.2kV-34.5kV (high-voltage side) and 120-600V (low-voltage side). Its features include:

 

  • Structural Form: Adopts Pad-Mounted (box-type floor-mounted) design with a fully sealed structure, reaching IP65/66 protection rating, and can be directly placed on concrete foundations.
  • Insulation Medium: Uses mineral oil or high-flash-point silicone oil as insulation and cooling media, with fire and explosion protection performance (complying with UL 1203 explosion-proof standards).
  • Voltage Adaptation: The high-voltage side supports multiple voltage classes such as 7.2kV, 12.47kV, 13.8kV, 25kV, 34.5kV, etc., while the low-voltage side outputs 120V/240V (single-phase three-wire) or 208V/480V/600V (three-phase four-wire).

Core Functions:

  • Voltage Conversion: Steps down medium voltage (e.g., 7.2kV) to low voltage (e.g., 240V) to meet the power demand of residential, commercial, or small industrial loads.
  • Safety Isolation: Isolates the high and low voltage sides through an oil-immersed insulation design to improve safety.
  • Overload Protection: Equipped with a temperature controller and pressure relief valve, which automatically cuts off power when the oil temperature exceeds the set value (e.g., 80°C) or internal pressure is abnormal.
  • Environmental Adaptation: Withstands harsh environments such as high temperature, humidity, and dust, suitable for long-term outdoor operation.

Typical Application Scenarios:

  • Residential Power Distribution: Provides single-phase 240V power for individual villas and residential areas, supporting high-power devices such as air conditioners and water heaters.
  • Commercial Facilities: Supplies 120V/240V power for convenience stores, small shopping malls, gas stations, etc., meeting the needs of lighting and cash register systems.
  • Small Industrial Loads: Provides power for farms and small processing plants, such as driving water pumps and small motors.
  • Renewable Energy Access: Serves as a step-up or step-down device in photovoltaic and wind power projects, adapting to distributed power generation scenarios.
