A30 Bus Insulators

The porcelain A30 bus insulators supplied by Eger are designed for applications that have high mechanical stresses, and are cantilever tested to guarantee that they meet industry standards. This ensures high quality, dependability, and safety, plus our high standards keep your production process running smoothly.

Eger stocks A30 porcelain bus insulators for the following voltage classes:

  • 5kv
  • 7.2kv
  • 15kv/95kv BIL
  • 15kv/110kv BIL
  • 23kv/150kv BIL
  • 34.5kv/200kv BIL

Porcelain A30 bus insulators (also referred to as bus bar insulators and bus supports) are utilized for high voltage applications where reliability and maximum “uptime” is paramount. Switchgear, power transformer, and bus-duct manufacturers use porcelain A30 bus insulators where high cantilever strength is necessary. Porcelain A30 bus insulators have a six-inch (6”) diameter to meet higher mechanical requirements. The high cantilever strength ratings meet the demands of industrial and utility customers around the world.

Porcelain A30 bus insulators are typically used to support long and short copper bus-bars. Ease of installation is key and Eger supplies porcelain A30 bus insulators with hot-dipped galvanized inserts, further reducing the amount of potential downtime. The porcelain A30 bus insulators supplied by Eger adhere to both the mechanical and electrical requirements of IEEE, IEC, NEMA and ANSI Standards. Testing is also performed in accordance with the applicable industry standards.

The glaze coating on the exterior of the porcelain A30 bus insulators supplied by Eger keeps dirt and pollutants from adhering to the insulator, making maintenance of porcelain A30 bus insulators unnecessary. The inserts are made from metals that will not oxidize or otherwise deteriorate, and are ideal for supporting copper and aluminum bus-bars.

Eger maintains an extensive stock of industry standard porcelain A30 bus insulators to help customers avoid long lead times. Due to the high quality of porcelain A30 bus insulators, production time can be lengthy, but Eger offers stocking agreements that enable your production process to run without interruptions. Typically, porcelain A30 bus insulators can be shipped within 24 hours from receipt of order.
