General Description
- Voltage ratings from 2.5kV to 8.7kV
- Current rating 7500A
- Flammability rating, UL 94 V0, V1
- Designed and tested to meet applicable CSA, IEC, IEEE standards

Applications
The PWRT series bushings are designed for indoor service, for ambient temperatures between –5°C and +75°C. Applications include:
- Bushing for liquid filled transformers
- wall or throat mounting
- For enclosed applications that are not exposed to sunlight
- Air to air designs available for above oil installations

Construction
- Cast in high dielectric strength Bis-A epoxy
- Positive oil seal
- Tin plated electrolytic copper conductors are standard. See options tab for alternatives.
- Multiple flat bar conductors for maximum contact surface
- Four to eight mounting holes with counter-bored weld recesses

Plating

Tin plated conductors are standard for transformer bushings. Available alternatives are silver or non-plated conductors.

Accessories: Gaskets

1/8”, 3/16” or 1/4" thick nitrile gaskets are available upon request
