Strain clamp is used to fix conductor and ground wire through insulators or link fitting to tower arms or substation structures. In according to the clamp construction and mounting way, the clamps include two types as compression type and bolt type.
NLL series bolt type aluminium alloy strain clamp is used to AAC and ACSR, the conductor may be wound by aluminium tape or performed armour rods for protecting.
