AUXILIARY STRAIN CARRIER
The Auxiliary Strain Carrier is a lightweight, portable tool designed for quick replacement of damaged insulators in de-energized suspension strings,
especially when the number of damaged insulators does not justify the removal and lowering of the entire string for ground replacement.
SAFETY PROCEDURE
When changing insulators in the de-energized suspension chains, handling the Auxiliary Strain Carrier requires special attention about its installation in the network, in order to avoid accidents
1. This tool is only used in de-energized networks.
2. Prior to the installation of the auxiliary strain pole, the electrician will first need to install a complete strain set (yoke + strain pole) and suitable for the insulator string in order to relieve the mechanical strain of the string and allow insulator decoupling.
3. After that, the nut and the auxiliary strain pole will be mounted on the insulator directly above the one to be replaced (changing one insulator at a time).
4. When coupling, make sure that the insulator cap is resting only on the upper base of the yoke when using model FLV11537-1, or on the upper
base of the nutswhen using models FLV30577.
| FLV11537-1
It has two Yokes made of cast aluminum alloy, in addition to two trunnions and two tensioning screws.

Approx. Weight: 8.15 kg (17.95 lb)
| FLV30577-3 | FLV30577-4
It has two Yokes that are coupled to the insulator cap with the help of shoes manufactured according to the insulator model (purchased separately), made of cast aluminum alloy, in addition to two trunnions and two tensioning screws.
Rated Work Capacity: 600 daN (1322 lb)
Approx. Weight: 10.40 kg (22,92 lb) 10.20 kg (22.48 lb)
NOTE
Removable shoes (purchased separately) are changed to fit different types of insulators. When the models available in this catalog do not meet the insulator specifications, the insulator drawing must be made available for evaluation by our engineering department for the development of the appropriate shoes.
