ZGS series pad-mounted transformer offers a low-cost, highly reliable, and intelligent urban power distribution solution.
• 3-phase pad-mounted transformers combine transformers, switchgear, fuses, tap-changers, low-voltage distribution equipment, and other auxiliary equipment to meet various user requirements, including energy metering, reactive power compensation, and low-voltage branching.
• Rated AC frequency is 50Hz/60Hz, and the maximum operating voltage is up to 38.5kV. Other capacities include 150kVA, 200kVA, 250kVA, 300kVA, 315kVA, 400kVA, 500kVA, 630kVA, 750kVA, 800kVA, 1000kVA, 1500kVA, and 2500kVA.
• Pad-mounted transformers are widely applicable in industrial parks, urban residential areas, commercial centers, high-rise buildings, and other locations.
• Products are primarily exported to North America, East Asia, Southeast Asia, the Middle East, and other countries and regions. OEM/ODM services are also available.
• Implementation standards: ANSI C57, IEC60067, GB 1094, GB17467-2010, GB/T 14048.1, GB 4208
