Intermediate tension insulator
Applies tension to a straight line of more than 100m or to an endless line, and absorbs expansion and contraction in the Tro-Reel unit due to temperature fluctuation.
●
Mounting an insulator on a bracket
Mount the intermediate tension insulator to
the intermediate tension insulator bracket
using nuts A and B.
●
Connection to Tro-Reel
<60A and 150A and 200A>
1. Loosen the intermediate tensioninsulator nuts. Set the distance
between the intermediate tension
insulator and the intermediate
tension insulator bracket to 150mm.
2. Connect the intermediate tension
insulator A and the Tro-Reel unit with
a center feed-in joiner.
(b)
(a)
(c)
For steps (a), (b) and (c), please follow the center feed-in
joiner mounting procedure in Section
8
.
3. Temporarily fix the Tro-Reel unit to the hangers in order
starting from the intermediate tension insulator side.
Terminal screws must be securely tightened.
Failure to do so may cause fire.

Set the gap to 15mm ± 5mm regardless of ambient temperature.
●
If using intermediate tension insulator, a center fixed insulator is also necessary.
Failure to do so may cause poor collector arm contact or separation from wires.
Notes
●
When using hangers with insulators, be
sure to mount two fo them.
Failure to do so may cause damage due to
falling of equipment.
●
Be sure to use a file of φ5 size.
Otherwise, falling may occur.
●
In the case of a porcelain insulator hanger
with it, Please contact Pansonic Electric
Works Co.,Ltd.
●
Mount the cover by all means.
Failure to do so may cause electric shock.

Center fixed insulator
This part is to be used in horizontal curves, and should be attached at the joint between straight and curved sections to apply tension in the straight section.
1.Mount center fixed insulators to
hangers (shown above).
2.Attach the insulator to the Tro-Reel
unit. Drill a
φ
5mm hole. Insert a
knock pin and fit on the cover.
