Not sure what the proper bushing replacements are for your in-service bushings? Hubbell | PCORE® Electric can provide a custom cross-reference guide to help!
Repairing a bushing is less expensive than purchasing a new bushing and you are able to maintain all of the original dimensions.
A typical bushing repair is a regasket of the bushing or a recore and regasket of the bushing. When a bushing leaks; however, tests well, a regasket will be performed in which the sealing components are replaced. When a bushing tests poor, a recore and regasket will be performed. During the recore of a bushing the bushing core will be replaced with a new PCORE® POC type core. Repaired bushings ship with the same warranty as a new bushing.
Save time and money spent lowering the oil level in the transformer, when replacing higher current bushings, by specifying the PCORE® Electric Company, Inc. Quick-Link bushing.
In 1999, PCORE launched the first Quick-Link bushings that allowed electric utilities to save costs by significantly reducing transformer outage time. The design was further expanded to 115kV and 138kV in 2017. PCORE’s Paper-Resin-Capacitor (PRC) and Paper-Oil-Capacitor (POC) Quick-Link bushings have the following benefits:
The PCORE® SET-Terminal is designed for use with field dielectric test equipment for more accurate, faster, and safer field power factor measurement of apparatus insulation at a substantial savings.
PCORE Electric launched the SET-Terminal in 2011 as an addition to their test terminal line. The SET-Terminal provided improvements from the traditional porcelain test terminal that has been used by utilities since the 1950’s.
Benefits of the SET-Terminal include:
- A faster testing process.
- Safer testing for test technicians.
- Less expensive testing because of less labor hours and equipment down time.
