Strain Clamps-NY(For ACSR-AAC Conductors)

    Strain clamps, also known as tension clamps, are used in power transmission lines to fix and connect conductors onto the tension insulator string or the fittings on poles and towers. They sustain the tensile force generated by the conductor.

For ACSR (Aluminum Conductor Steel Reinforced) and AAC (All Aluminum Conductor) conductors, there are several types of strain clamps available:


1.Quadrant Strain Clamp - Aluminum (SD130S): This is an aluminum bolted deadend for transmission line construction with all aluminum, ACSR or aluminum alloy conductor, or for Alumoweld shield wire. It has a clamping range of 0.460"-0.940" and the ultimate body strength is 30,000 lb.


2.Strain Clamp, Snubbing (785002000): This strain clamp has a conductor range of AAC-600-900 MCM, ACSR- 556.5-795 MCM, and a diameter range of 0.870”-1.108”. The ultimate body strength of this clamp is 14,000 lbs.


3.NY-BG Hydraulic Strain Clamp: This type of strain clamp is used specifically for aluminum-clad ACSR.
