Components for curved section installation
When installing the Tro-Reel on curved
sections, tension must not be applied to
curved sections. Therefore, for installation
on curved sections, the line must have
some straight sections where center fixed
insulators, end tension insulators, or
intermediate tension insulators can be
installed for tension application.
Notes
Please follow the instructions below to prevent poor
collector arm contact and separation from wires:
Be sure to attach center fixed insulators at the
●
joint between the curved section and the straight
section to maintain tension in the straight section.
Hangers should be positioned at an interval of
●
0.5m or less for curved sections and 4m or less
for straight sections.but the place where the
vibration is intense,and outdoor use, Hngers
should be positioned at interval of 2m or less for
straight sections.
If using hangers with insulator, be sure to use
●
twoof them in places where center fixed insulators
are mounted.
Do not position joints in curved sections.
●
Power must be supplied to the Tro-Reel unit in
●
straight sections.

For brackets adjacent to center fixed insulators,
use a
- shape bracket 75mm×40mm×5mm
or larger. Failure to do so may cause poor
collector arm contact or separation from wires.
