11kV/0.4kV, 1000kVA, Dyn11 connection, fully sealed and maintenance-free, compliant with IEC 60076 / ANSI standards.
The 11kV 1000kVA compact substation is a factory-prefabricated, integrated outdoor packaged power distribution unit. It integrates high-voltage switchgear, a distribution transformer, low-voltage distribution panels, and protection and control systems into one or more enclosed housings. Featuring a compact structure, small footprint, fast installation, reliable operation, and maintenance-free performance, this 1000 kva compact substation is widely used in urban power grids, industrial parks, residential communities, commercial buildings, new energy power stations, and infrastructure projects. As a complete 11kv compact substation, it delivers the performance of a conventional indoor substation in a fully sealed, weather-resistant enclosure—eliminating the need for a dedicated building. The growing demand for rapid deployment and minimal site preparation has made compact substations a preferred solution for both utility-scale and distributed power distribution networks.
• Compact size, with only one-tenth of the footprint of a conventional substation
• Leak-proof oil design and maintenance-free operation
• Zero-maintenance design
• 3-year warranty
Product Features
The corrugated tank and fully sealed design of the 1000 kva compact substation effectively isolate air and moisture, slowing insulation oil aging and enabling truly long-term maintenance-free operation while reducing O&M costs.
A high-quality step-lap core and robust structural design effectively reduce hysteresis loss and noise, ensuring quiet and reliable performance across all compact substations applications.
The enclosure uses a C4/C5 high-grade anti-corrosion powder coating, making it suitable for harsh outdoor environments with strong protection and long-term open-air operation — a key advantage for 11kv compact substation deployments.
Vacuum oil filling completely removes internal bubbles, improves insulation strength, reduces partial discharge, and extends service life.
