Self-Gripping Clamps
The self-gripping clamps can be used to anchor and to string conductors (aluminum ACSR…) and steel rope. The body is made of high strength heat forged steel in order to minimize the ratio between weight and working load. The galvanization treatment on the surface protects from oxidation. Condux Tesmec clamps can be provided with machined body clamps or with interchangeable jaws as per the following tables. The most important characteristic of the clamp with interchangeable jaws is the ability to use the same clamp for working on conductors ropes or OPGW of different diameters by only changing the jaws. This feature helps reduce operating costs. New Condux Tesmec clamps can accept a large range of rope and conductor diameters by using a small number of interchangeable or machined jaws.
Special clamp models without jaws are available also for use on conductors.
Special jaws are available upon request.
Warning: it is strictly forbidden to use jaws of different manufacturer.

Conductor
Wire pulling clamps
- Constructed of high strength heat forged steel galvanized for toughness strength and corrosion resistance
- Clamps feature a full range of interchangeable aluminum liners to be inserted between the upper and lower jaws of the clamp
- Suitable for conductor sizes ranging from .276 to 1.811 inches (7 to 46mm)
- Jaws and liner inserts are round to provide maximum contact and gripping power
- Recommended for use on bare aluminum ACSR AAC ACSS and copper conductors as well as a range of cables
- Locking loop handles allow the jaws to be held in an open position for easy placement on wire or cable
