The Light-duty Strain Carrier for cold end and suspension insulator strings has been designed for conductors up to 636 MCM (Diam. 25.15 mm - 1") GROSBEAK, for replacement of single deadened insulator strings of 69 kV through 145 kV energized systems and suspension strings of 110 kV through 145 kV energized systems.
The excellent mechanical characteristics of the Ritzglas® Insulating poles allows for the reduction of the diameter of the strain poles to only 32 mm (1-1/4”), offering thus a proportional reduction of the hardware dimensions, providing for a lighter and more practical equipment, making transportation and handling much easier.
The metallic tools used at the cold-end are used either on deadened or suspension works, offering versatility to the set and making the equipment more economical and attractive, from a cost-benefit perspective.

APPLICATION OF EACH TOOL
1. Cold-end yoke FLV13352-1
This tool is used on deadened and suspension strings.
On deadened strings, it is attached to the tower structure through clevispin and hook-chain assembly, coupled directly to the ball-link extension, with of up to diam. 22 mm (0.9") and rabbet with of up to diam. 38 mm (1.5").
On suspension strings, it is attached to the tower structure using the attachment support (FLV13356-1).
2. Attachment Support FLV13356-1
Attached to the end of the tower structure, it serves as a support and attachment of the cold-end yoke (FLV13352-1) when changing suspension insulator strings.
3. Hot-end Yoke FLV12192-1
Attached directly to the conductor, needing no wire grip for straining when replacing a cold end insulator string.
4. Insulating Strain Pole FLV13780-1
Cold-end clevis for attachment to the strain jack and 10 (ten) pairs of hotend stainless steel pins are used for support and attachment of the hot end yoke, without the need to use adjustable pole clamps when replacing insulators on cold end structures.
5. Insulating Strain Pole FLV13130-1
Used to support the conductor with the strain jack (RE401-1998) attached to one end and a spiral hook (FLV13006-1, FLV13006-2, FLV13006-3) to the other end, when changing suspension insulator strings.

6. Strain jack RE401-1998
To be attached to strain pole (FLV13780-1), through eye-clevis assembly and to cold-end yoke (FLV13352-1), through small trunnions (RE401-2068).
NOTE
Strain jacks with different lengths are available upon request.
7. Small Trunnion RE401-2068
To be attached to strain jack (RE401-1998) using a ratchet wrench (RM1948-3), in order to strain the conductor, transferring load from the string to the strain carrier.
8. Spiral Hooks FLV13006-1 / FLV13006-2 / FLV13006-3
Attached to strain pole (FLV13130-1), it grips the conductor to support it when changing suspension insulator strings. Different lengths available depending on the length of the hot-end hardware of the insulator string.
9. Ratchet Wrench RM1948-3
Despite this tool not being included in the strain carrier set, it is recommended for application on the small trunnion (RE401-2068).
10. Canvas Bag FLV19286-1
Used for transport and conditioning of the strain poles FLV13780-1.
11. Canvas Bag FLV19286-2
Used for transport and conditioning of the strain poles FLV13130-1.
12. Multi-purpose Handbag ATR09962-1
For conditioning and transport of distribution carrier component.
