A20 porcelain bus insulators are offered for the following voltage classes:
• 5kv
• 7.2kv
• 15kv/95kv BIL
• 15kv/110kv BIL
• 18kv/125kv BIL

Porcelain A20 bus insulators are typically used to support copper bus-bars, and are commonly used in high-voltage switching applications. Meister International supplies porcelain A20 bus insulators that have aluminum inserts to for durability and ease of installation.

The design of porcelain A20 bus insulators takes into account both the mechanical and electrical requirements of IEEE, IEC, NEMA and ANSI Standards. Our A20 porcelain bus insulators are cantilever tested and additional testing is performed to ensure our products perform in accordance with the applicable industry standards.
