200A, 15kV Rotatable Feedthru Insert
The CEE STT-15/200 rotatable feedthru insert is used to provide dualbushings from a single apparatus bushing well. In order to add in-line arresterprotection to the high-voltage circuit for pad-mounted transformers, the rotatable feedthru insert must be used. It also makes the conversion from radial-feedtransformers to feedthru transformers more easily and practically. The rotatable feedthru inserts aremolded using high quality peroxide-cured EPDM insulation. Combing with a comparably and submersible connection insert, a fully shielded and submersibleconnection for deadbreak operation is achievable. Its built-intorque-limiting ratchet prevents operators from accidentally breaking bushingwell studs during installation.
