• 72.5 kV
• 145 kV
• 245 kV

Ratings Checklist

• Confirm the operational voltage level.
• Consider peak demand load evaluation.
• Ensure compatibility with existing equipment.

Insulation Medium

Types of Insulation Used

Various insulation mediums are available for high voltage switchgear, and the choice will significantly impact performance and maintenance. Common types include:

• Air Insulated Switchgear (AIS): Traditional, less expensive, suitable for most applications.
• Gas Insulated Switchgear (GIS): Compact, higher reliability, excellent for space-limited environments but generally more expensive.

Considerations for Insulation Medium

• Evaluate space requirements.
• Assess environmental impacts (e.g., pollution).
• Determine long-term maintenance needs.

Standard Compliance and Certifications

Importance of Compliance

Ensure that the high voltage switchgear adheres to relevant standards and certifications, such as:

• IEC standards (International Electrotechnical Commission)
• ANSI standards (American National Standards Institute)
• Local regulatory requirements

Compliance guarantees that the switchgear not only performs as required but is also safe and efficient.
