Description
ISAR-S load-break disconnector switches are designed for low-load breaking overhead MV
electrical lines.
Equipped with an air-break technology system combined with an isolating switch in series,
this device provides visible opening and great safety in operation.
ISAR-S switches are suitable for overhead distribution networks up to 36 kV, and especially
those requiring a high level of insulation:
• No maintenance required.
• Easy pole top mounting.
• Line works can be carried in safe conditions thanks to the visible opening and high level
of insulation.
• A manual control mechanism is available with a rod assembly and padlockable lever.
• Whip breaking system.
• The ISAR-S switch control mechanisms are equipped with a tumbler spring system which
directly operates the mobile shaft.
The operating speed is not dependant on the operator.
• Height of the pole from 9 to 11 m.
• Synthetic Insulators designed with a central part in epoxy resin. The flexible skirts in over
molded silicone provide an important creepage distance and a good protection against
vandalism.
