Product Overview
- Urban Core Distribution Network Branches: Urban core areas have high load density (a single branch covers 2000-5000 households) and high requirements for power supply reliability (power outage tolerance time < 5 minutes). The low loss and intelligent cooling system of this transformer can cope with peak loads (120% rated load). Condition-based maintenance monitors the equipment status in real time through sensors and only performs maintenance when abnormalities occur, reducing operation and maintenance costs by 40% while avoiding unnecessary power outages affecting residents' lives.
- Large Commercial Complexes: Large commercial complexes have large daily load fluctuations (low in the morning and high in the evening, with a difference of up to 60%) and require 24-hour continuous power supply. The low-loss characteristic of transposed conductors adapts to load fluctuations, intelligent oil level monitoring can prevent oil leakage risks, and condition-based maintenance does not require frequent shutdown inspections, ensuring continuous power supply for shopping malls, hotels and other places and improving user experience.
