The oil-immersed four-position load switch is designed specifically for ring-type American box transformers and ring main cabinets, meeting all the requirements of IEEE, IEC, and GB standards. Can be used in grounded or ungrounded systems.

When installing an oil immersed four position load switch, being close to the transformer core can minimize the capacitance of the internal connecting cables, thereby significantly reducing ferromagnetic resonance in the circuit. There are two types of switches available: side-mounted and top-mounted, which can be used for ordinary American-style box transformers or buried transformers.

Dry the transformer before use.
