■ Intermediate tension insulator
Mounting an insulator on a bracket
●
Mount the intermediate tension insulator to
the intermediate tension insulator bracket
using nuts A and B.

13mm or less
Connection to Tro-Reel
●
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.

For steps (a), (b) and (c), please follow the center feed-in
joiner mounting procedure in Section
3. Temporarily fix the Tro-Reel unit to the hangers in order
starting from the intermediate tension insulator side.

Caution
Applying tension to the Tro-Reel unit
●
1.To take up the sag of the Tro-Reel
unit, tighten the tension bolt nus
until the coil spring is the length
indicated below.
2.Please install a center fixed
insulator in being making the
space become to 15mm ± 5mm.

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.

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.
