TENSION WEDGE CLAMP

Tension fittings include tension clamps of various kinds, which are used to fix the wires and cables to the tension-tension pendants corner supports.
Clamps the load of tension wires (cables) in normal mode when exposed to wind and ice.

Clamps, seeing loads of tension wires and cables must provide strength sealing wires (cables) is not less than 90% of the theoretical strength of the wires (cables) on the break. And also to ensure a reliable electrical connection. Relative resistance electrical contact to the terminals where the wire (rope) is cut, should not exceed one.

Depending on the design and method of mounting tension clamps are divided into wedge, bolt, wedge, compressible, fang.

Flaps wedge NKK-1-1B is designed for attachment of steel-aluminum wire sizes from 10 to 50 mm² wire rope section from 25 to 86 mm² to the tension-tension pendants corner supports. Clips NKK-1-1B equipped with a supply of wedges, which number should be indicated, depending on wire size and diameter of the rope used on the line. Terminal is connected to the ears U1-7-16 and U1K-7-16.

Clamp NKK-2-1

Number wedge	Mark wire GOST 839-80	Diameter of the rope, mm		Failure load, kN, not less	Weight, кg
		to GOST 3063-80	to GOST 3071-74
2	-	11,0	13,5 15,5	120	3,10

Flaps wedge koushny NKK-2-1 is designed for attaching wire rope diameter from 11.0 to 15.5 mm for tension-tension pendants corner supports. Clip NKK-2-1 is equipped with a supply of wedges, which number should be indicated, depending on the wire size and diameter of the rope used on the line. Mounting clamp wedge type does not require cutting the wires.
