1.2. Storage and transport
The operating mechanisms can be transported to the place of storage and installation by any means of trans-
port, provided that they are protected against moisture
During transport, the operating mechanisms should be secured against shifting and colliding with each other
or with vehicle parts. An additional protection for longer transport is a bag with moisture absorbing substance.
It should be removed from the operating mechanism before energizing the heater.
It is forbidden to store the operating mechanisms on their backs in a stacked manner. The operating mecha-
nisms should be positioned vertically as shown in the drawing in section 1.1. This is the only acceptable drive
storage system.
2. DESCRIPTION
NSO80 motor operating mechanisms are intended for maneuvering HV outdoor disconnectors and earthing
switches which angular displacement is up to 192° and both closing and opening operations anti-torque is up
to 800 Nm. The operating mechanisms are compatible with disconnectors and earthing switches produced
by ZWAR, operating at 110, 220 and 400 kV voltage (e.g. ONIII110..., ONI220, ONS..., UNIII110...). They replace
manual or pneumatic operating mechanisms as an upgrade of existing HV disconnectors.
CAUTION!
When storing the operating
mechanisms, protect against moisture
until the heater will be energized.
