Outdoor Tyoe IP4X Compact Substation Transformer for Real Estate and Buildings
Product Description
• Compact substations are available in different capacities ranging from a few kVA to several MVA. The rating depends on the transformer size and switchgear specifications.
• Major equipment within a compact substation include:
- Medium voltage switchgear for incoming and outgoing feeders
- Distribution transformer for voltage transformation
- Low voltage switchgear for distribution to consumers
- Protection relays and control panels
- HV and LV cable terminations
- Auxiliary systems like lighting, space heaters, ventilation etc.
• Depending on the design, compact substations may have either indoor or outdoor switchgear. Outdoor units are more common due to lesser space requirements.
• Oil immersed transformers within compact substations are mounted on wheel-mounted steel frames for easy movement and maintenance access.
• Dry type transformers are either cast coil or vacuum pressure impregnated type. They are more efficient, eco-friendly and require lesser maintenance.
• Compact substations offer benefits like scalable and flexible capacity, ease of installation and commissioning, robust design for withstanding harsh environments, and plug-and-play capability.
• They find wide usage as distributed power sources for commercial buildings, industrial complexes, utility networks and urban infrastructure projects.
• Advanced compact substations use remote monitoring systems for real-time performance tracking and efficient operation.

Material
1.The cabinet door adopts a double beveled edge process, which increases the structural strength of the same material by 50%.
2.The installation holes are all made using a multi-layer stamping and stretching process, which reduces the sliding wire situation by more than 80%.
3.The inlet and outlet holes adopt a composite structure of knockdown holes and square holes, which can be flexibly selected during on-site installation.
4.The box adopts a double folding process, which increases the structural strength of the same material by 50%.
5.The control circuit adopts a composite design of debugging mode and fire protection mode, greatly reducing the burning of fan and water pump equipment designed for fire protection during debugging.
