High Voltage Switchgear Draw Out Cast Resin Dry Type Electrical Power Transformer IP54
High Voltage Switchgear Draw Out Cast ResinDry Type Electrical Power Transformer
Product Description
Components
• Preassembled substations mainly consist of:
- High voltage switchgear
- Distribution transformers
- Low voltage switchgear
- Protection devices
- Metering equipment
- Control systems
They integrate all these components within compact enclosures.
Construction
• The box bodies are made of materials like structural steel, aluminum alloys and flame retardant composites.
• They provide protection against weather, corrosion and intrusion.
• Internal components are factory assembled and tested before installation.
Applications
• Used for ring, dual power source or radial distribution systems.
• Suitable for:
- High-rise buildings
- Residential communities
- Industrial parks
- Mines and oilfields
- Temporary construction sites
Advantages
• Compact design with small footprint - around 1/10 to 1/5 of conventional substations.
• Lower investment and construction costs.
• Easy installation, operation and maintenance.
• High reliability and safety due to enclosed design.
• Mobility - Can be relocated when needed.
