The Wire Connection Strain Clamp Bolts
Wire Connection Strain Clamp Bolt is a fundamental member of overhead power transmission and distribution networks. Its primary role is to securely attach conductors or shield wires to suspension or strain insulator strings or support structures like poles and towers, specifically to counter the mechanical tension (strain) of the line.
Making these bolts is a test of precision engineering. Typically constructed of high-strength steel alloys, the bolts are severely machined to precision thread specifications and dimensional tolerances. The head is typically specially shaped (e.g., hex, square, or winged) to facilitate tightening with special hot-stick tools in the live-line crew's hands. Aids to long life, the bolts receive a heavy protective coating, commonly hot-dip galvanizing, to facilitate their resistance to severe environmental corrosion. Strict quality control, including tensile strength testing and measurement checking, ensures that each bolt meets strict industry standards for safety and reliability.
The Wire Connection Strain Clamp Bolt is practical by performing important functions:
1. Mechanical Anchoring: It translates the entire tensile load of the conductor or ground wire through the clamp body to the supporting structure or hardware.
2. Vibration Damping: The right torque and installation allow the whole clamps assembly to be subjected to fatigue caused by wind-generated conductor vibration.
3. Electrical Continuity: In some installations, it creates a firm electrical contact between the clamp body and the conductor.
4. Security: Its construct does not loosen due to vibration or thermal cycling, ensuring a fail-safe connection that is vital for grid stability.
Essentially, this simple bolt is the reliability and essential safety anchor, holding conductors tightly in suspension and electrically connected under constant mechanical tension and harsh weather conditions for decades. Correct choice and proper torque application are paramount to its operation.
