Unit Substation
Introduction to Unit Substation
Suitable for hot and humid climates
Unit Substation is a type of outdoor substation specifically designed for harsh climatic conditions such as very hot and humid regions. These substations are installed directly on a concrete foundation without the need for a metal enclosure or room, and feature IP54 protection. The substation base is made from standard steel profiles and coated with hot-dip galvanization for full resistance against moisture and corrosion. Medium and low voltage equipment is also designed for outdoor use and is usually connected directly to the transformer.
Features and Technical Specifications of Unit Substation
- Suitable for: high temperature and high humidity regions (hot and humid climates)
- Base structure: made of welded standard steel profiles with hot-dip galvanization
- Design: fully outdoor, no enclosure required
- Equipment connection: direct connection of switchgears to the transformer
- Protection rating: IP54 against moisture, dust, and rainfall
- Installation: on a concrete foundation, no complex structure required
Applications of Unit Substation
- Industrial projects in coastal and humid regions
- Desert and high-temperature areas
- Oil, gas, petrochemical, and refinery projects
- Renewable energy installations
Advantages of Unit Substation
- High durability: suitable for harsh climatic conditions with high temperature and humidity
- Lower cost: reduced final cost due to the elimination of an enclosure
- Easy installation: mounted on a ready concrete foundation
- Low maintenance: reduced repair and operational costs
- Direct connection: direct interface between switchgears and the transformer via busduct and cable box to ensure IP54 protection
