Why Are Bolt-type Tension Clamps Suitable For Spans ≤100 Meters?

From a structural mechanics perspective, for spans ≤ 100 meters, the conductor tension, tower spacing, and sag amplitude parameters of bolted type strain clamp are within the range covered by the design verification.

From the perspective of line installation and operation conditions, when the span exceeds 100 meters, factors such as conductor sag, wind load, and ice load all increase significantly. For dead end strain clamp, with common specifications and materials, its friction, bolt preload, and clamp strength may deviate from the original design expectations. Conversely, when the span of bolted dead end clamp is controlled within 100 meters, the tension, sag curve, and tower arrangement within the system are easier to construct according to standards, thus maintaining the clamp's intended function.
