LIGHT-WEIGHT STRAIN CARRIER
It is designed for Grosbeak conductors, up to 636 MCM (Ø 25.15 mm), for changes of single strings of 69 to 145 kV anchorage and 110 to 145 kV suspension on live lines.
The excellent mechanical characteristics of the RITZGLAS® tube allow the strain pole diameter to be reduced to just 32 mm (1-1/4”), with consequent proportional reduction of metal parts, making it a light and practical set for easy handling and transport.
Metal tools that work on the de-energized side are used for both anchoring and suspension, providing versatility to the assembly and making it more economical and attractive in terms of cost effectiveness.

APPLICATION OF EACH TOOL
1. FLV13352-1 (cold-end yoke)
It is applied to anchor and suspension strings.
In anchor strings, it is coupled to the tower crossarm, with the help of the clevis pin and the string, fitted directly into the ball clevis extension, up to 22 mm, and shoulder, up to 38 mm.
In the suspension string it is coupled to the tower crossarm with the aid of the support (FLV13356-1.
2. FLV13356-1 (support)
It is supported and mounted to the end of the tower crossarm to support and couple the cold-end yoke (FLV13352-1) in suspension string changes.
3. FLV12192-1 (hot-end yoke)
It couples directly to the cable, eliminating the use of wire grip when replacing the anchor string.
4. FLV13780-1 (insulating strain pole)
The cold-end yoke is attached to the strain jack. The 10 pairs of hot-end pins support and couple the yoke without requiring an adjustment pole clamp when changing the insulator string in the anchor structure.
5. FLV13130-1 (insulating strain pole)
With the Strain Jack (RE401-1998) coupling at one end and the Spiral Hook (FLV13006-1, FLV13006-2, FLV13006-3) at the other end, this tool is used to support the cable in suspension string exchange.
| Catalog Reference | Insulating Length (m) | Working Length (m) | |
| Minimum | Maximum (ft) | ||
| FLV13780-1 | 3.60 | 3.80 | 8.30 |
| FLV13130-1 | 4.00 | 4.75 | 4.75 |
NOTE
Poles with different lengths can be provided upon request.
6. RE401-1998 (strain jack)
Attachable to the strain pole (FLV13780-1) by the eye yoke system and to the dead yoke (FLV13352-1) through the small trunnion (RE401-2068).
NOTE
Bolts in other lengths can be purchased on request.
7. RE401-2068 (small trunnion)
Threaded into the strain jack (RE401-1998) with the aid of the ratchet wrench (RM1948-3) to tension the conductor, transferring the string load to the strain set.
8. FLV13006-1 / FLV13006-2 / FLV13006-3 (spiral hook)
Coupled to the Strain Pole (FLV13130-1), the spiral hook secures the conductor to support it in the suspension string change. Each of the 3 hook sizes is used according to the length of the hot-end hardware of the insulator string.
9. RM1948-3 (ratchet wrench)
Although this tool is not included in the strain set, we recommend purchasing it for single trunnion application (RE401-2068).
10. FLV19286-1 (bag)
Used for storage and transporting of strain pole FLV13780-1.
11. FLV19286-2 (bag)
Used for storage and transporting of strain pole FLV13130-1.
12. ATR09962-1 (multi-purpose handbag)
Used for storage and transport of the other components of the set.
