Bus insulators are used by switchgear, power transformer and bus-duct manufacturers for all 5kv to 15kv/110kv BIL applications where ‘uptime’ is paramount. A20 bus insulators typically have high mechanical stresses placed on them. To guarantee industry standards are met cantilever tests are performed to ensure product integrity.
A20 bus insulators or bus bar insulators are offered for 5kv, 7.2kv, 15kv/95kv BIL and 15kv/110kv BIL voltage classes. Bus insulators are typically used to support copper bus-bars. In addition, bus insulators are commonly used in high-voltage switching applications. Meister International supplies A20 bus insulators that have aluminum inserts to make installation easy.
Maintenance of bus or bus bar insulators is really not required as the glaze coating on the exterior of the insulator keeps dirt and pollutants from adhering to the insulator. The inserts are aluminum and are ideal for supporting copper bus-bars.
The design of porcelain A20 bus insulators or bus bar insulators takes into account both the mechanical and electrical requirements of IEEE, IEC, NEMA and ANSI Standards. Testing is also performed in accordance with the applicable industry standards.
Manufacturing high-quality porcelain insulators is time and energy intensive. Meister International helps customers avoid long leadtimes by stocking industry standard porcelain A20 bus insulators. Stocking agreements are offered so that your production process can run without interruption. Typically, A20 bus insulators and bus bar insulators can be shipped within 24 hours from receipt of order.
