General Description
- Voltage ratings from 5kV to 46kV
- Impulse rating up to 250 BIL
- High strength
- Partial discharge free
- Flammability rating, UL 94 V0, V1
- Various mounting insert configurations available, see options tab for alternatives
- Manufactured to specific industry standards (ANSI C29.1 and ANSI C29.10)
Applications
The PII20A series insulators are designed for indoor service, for ambient temperatures
between -25°C to +75°C. Applications include:
- supports for switchgear bus
- disconnects
- dry type transformers
- other special power applications.
Construction
- Cast in high dielectric strength Bis-A Epoxy
- Zinc plated steel mounting inserts are standard, other materials available upon request.
- Insulators rated 95kV BIL and higher have inserts connected to prevent partial discharge on
unused inserts

* A11 PII20A insulators are 4.0" diameter, except CAT.NO.s PII20A38 and PII20A46 which have a 4.25" diameter flared base for additional mechanical strength.
** Mechanical Withstand values are 80-90% of ultimate values and are specified for four and five inserts configurations. Values for one, two, and three inserts configurations are lower. Working loads up to 50% of published values are considered safe for all insert options, but maximum loading will vary with the application and conditions of use. Cantilever forces were applied 2.50” above the loaded end of the insulator.
