1.The body is forging of high strength aluminum alloy and it can protect the OPGW effectively, using the bolt not to slip line and hurt the line. 2.Need to specify when ordering diameter and fiber cable models. 3.All gripping jaws are produced with new technology to increase jaw life 4.Adopt alloy steel , heat treatment strengthened. 5.For tightening or adjusting sag of ground wire, light weight. 6.It is suitable for the steel strand adjustment of the guyed tower and the ground wire tightening.

TYSK Self Gripping ClampsThe self-gripping clamps can be use to anchor and to string rope. The body is made of high strength hot forged steel in order to minimize the ratio between weight and working load.
Model	Rated load(kn)	Apply range(mm)	Weight(kg)	Remark
SKJL-2	20	Φ4-22	1.3	Steel cable; conductor
SKJL-3	30	Φ16-32	2.5	Copper wire; Aluminum steel; LGJ; Insulated overhead line

They are for holding the OPGW overhead optical ground wire, cable diameter is the same as grip size, in order to ensure clamping firmly, reduce the pressure of clamped parts cable is clamped part and protect the inside fiber of cable not to be damaged.After the accompanying fixture clamps the ground wire, the pulling force acts on the pull ring, and the sliding axis of the pull ring slides in the body wire slot, driving the connecting plate, and the movable jaw seat rotates accordingly. Due to the secure hinge connection between the other end of the movable jaw seat and the jaw, when rotating, the movable jaw is forced to press down along the pin axis, and the cable is pressed onto the fixed jaw seat. The greater the tension on the pull ring, the greater the downward pressure on the movable jaw to ensure that the ground wire is tightly clamped by the movable jaw and the fixed jaw.
