Overview
The Strain Clamps are designed to secure conductors and ground wires with insulators or link fittings to tower arms and substation structures. It is mainly used in applications involving distribution or transmission lines. U bolts, nuts, and washers are required to fix the conductors to the body. The additional special liners or armor tape provides protection for the conductor from subsequent damages.
