Tension wedge clamp, type HK-1-1
Tension wedge clamp, type НК -1-1 is intended for fixing of aluminum and copper conductors of a cross-section 16 to 95 mm² to tension insulator strings of the angle-tension towers. Parts of the clamp, type НК -1-1 are made of the following material: body – steel; wedges No. 1, 2, 3 – aluminum; wedges No. 1A, 2A, 3A – brass; seal for copper conductor – soft copper. Copper seals are not supplied with the clamps. Installation of the wedge clamps do not require cutting of wire/conductor. Depending on the wire/conductor make, the clamp is supplied with a wedge of appropriate gage. Tension wedge clamp, type НК -1-1 is connected with socket tongues, type У1-7-16 and У1K-7-16. Tension wedge clamp, type НК -1-1 meet the requirements of TU U 31.2-30255335-002:2006.
