Product Details

The tension clamp NLL-1 is suitable for the overhead lines of 10kv and below. It is used to fix the aluminum stranded wire or the steel core aluminum stranded wire on the tension rod. When used for the overhead insulated aluminum wire, it is used in conjunction with the insulating cover to provide insulation protection. The wedge-shaped strain clamp has the advantages of very small hysteresis loss, light weight, convenient installation, etc., which meets the requirements of energy saving and consumption reduction in the transformation of the national grid. The main body of the product is made of aluminum alloy, and the bolts and nuts are made of hot-dip galvanized material.
