Bay-o-net Fuse Holder
Vertical and horizontal mounting are avaliable.Details
It is designed for use in pad mounted or subsurface distribution transformers filled with Envirotemp FR3 fluid, transformer oil or approved equivalent. The assemblies combine the ease of hotstick operation with the safety of deadfront construction.
- 8.3 - 23 KV : 150 kV BIL.
- 38 KV : 200 kV BIL
Used to avoid re-energize faulted transformers.Details
Used in series with a Bay-O-Net type fuse or MagneX Interrupter. Isolation links are not fuses and do not have an interrupting rating. During a transformer failure, the isolation link will melt so that the opened primary circuit of a faulted transformer cannot be re-energized by the line crew.
ELSP Current-limiting Backup Fuse
Used in series with low current primary protection devices.Details
The ELSP fuse is designed for use in transformer oil, Envirotemp FR3 fluid, or an approved equivalent. The fuses highly efficient current limiting section minimizes the effects of high fault current stresses on equipment and the distribution system.
- 8.3 To 23 KV : 30 To 330 A
- 15.5 KV : 30 To 300A
They are designed conform to IEEE Standard 386, and IEEE Standard C62.11.Details
The M.O.V.E. Surge Arrester combines metal (zinc) oxide varistor technology in a pre molded rubber elbow to provide overvoltage system protection in an insulated, fully shielded, submersible, deadfront device.
- 15 KV Class : 3 To 18 kV
- 25 KV Class : 9 To 21 kV
- 35 KV Class : 18 To 30 kV
Meets all the requirements of ANSI/IEEE Standard 386.Details
Bushing Insert threads into a universal bushing well to provide the same function as an integral loadbreak bushing. Using bushing inserts makes field installation and replacement possible and efficient.
line crews need not be exposed to high-voltage conductors and hot transformer fluids.Details
Externally operated series multiple switch is used to change connection of de-energized transformer windings between series and parallel to provide different common transformer voltage ratios.
It fully meets the requirements of IEEE Standard 386.Details
Rotatable Feedthru Insert is used to provide dual bushings from a single apparatus bushing well. It makes converting radial-feed transformers to feedthru transformers and adding in-line arrester protection both easy and practical.
ELX Full Range Fuses
It is ideal for installations where flame discharge and loud operation are undesirable.Details
