Joint Protectors & OPGW Counterweight & Running Board
Joint Protectors
When conductor midspan joints are compressed during the process of pulling conductors over the towers they need to be covered with an enclosure which prevents them from bending while travelling through the Pulley Blocks.
Designed to protect mid-span joints while being pulled over Pulley-Blocks during stringing.
Please specify on the order:
- Mid-span joint
- Conductor diameter
- Max. compression sleeve OD
- Length after compression
| Part No. | OD (mm) | Min pulley grove width (mm) | Max CS ⌀ | CS length after compression max (mm) | TL* (mm) | BL (kN) | Weight (Kg) |

OD - outside diameter | CS - compression sleeve | O.D. CS - outside diameter of compression sleeve | TL - total length including rubber insert
* total length of joint protectors can be made up to order.
OPGW Counterweight
This device has the function to prevent rotation of OPGW during the stringing process. The new and very flexible design prevents problems when pulling over angled towers. We recommend using two counterweights to avoid rotation while one is on a pulley block. Delivery includes clamp unit and counterweight (approx. length 3 m), to avoid twisting.
Customization options available upon request.
Please specify when ordering:
- Rope Ø
- Groove Ø of pulley block
