EFO outdoor disconnectors are mechanical switches that,used in MV distribution systems for opening and closing of outdoor lines without current.They are producing according to IEC 60129 and IEC 62271-102 with ISO 9001 quality assurance system. EFO M.V outdoor disconnectors have TSE certificates. Technical and Constructional Features:

- Type tests performed acc. to IEC 60129 and IEC 62271-102 - Frame , shafts and hand drive mechanism are hot deep galvanized.

- Porcelain insulators are C type and creepage distance 20 mm/kV

- Fix and moving terminals are made of electrolytic copper and silver plated so power lost minimized.

- Disconnectors are delivered in wooden case with hand drive mechanism.

- There are corrosion resistive materials used between frame and shafts.

- There are double springs where fixed and moving terminals in touch so that contact resistances

are minimized.

- There are mechanical lock system on earthing types. - Earthing types have outgoing side earthing of discconector.
