Description

 

This Rockwill outdoor pad-mounted transformer is a fully sealed, American-style prefabricated substation that integrates a high-voltage load switch, high-voltage fuses, and the distribution transformer within a single oil-filled tank. Designed for urban and rural distribution networks, it functions as a compact power transformation and distribution point.

The transformer tank is fully sealed and equipped with oil temperature gauge, oil level gauge, pressure gauge, pressure relief valve, and drain valve for comprehensive operational monitoring. The product supports ring network and terminal connection configurations, with plug-in fuse options that can be replaced without affecting the transformer oil.

 Key Features

  • Integrated design:High-voltage load switch and fuses are housed inside the transformer oil tank for a compact footprint and reliable protection
  • Fully sealed construction: Hermetically sealed tank prevents oil leakage and moisture ingress, extending service life
  • Plug-in fuse system:Fuses can be replaced without disturbing the transformer oil, simplifying maintenance
  • Flexible configuration: Supports ring network and terminal connection modes to suit different distribution network topologies
  • Comprehensive monitoring :Equipped with oil temperature gauge, oil level gauge, pressure gauge, and pressure relief valve for real-time status indication
  • Durable enclosure : High-strength, corrosion-resistant steel enclosure suitable for harsh outdoor environments
  • Low noise : Designed for quiet operation in residential and urban areas
