What is the horizontal radial clearance for spans?

Horizontal radial clearance is the safe horizontal distance kept between a span and nearby obstacles so the conductor won’t strike anything when it sags or sways under wind and temperature changes. This clearance sets the envelope around the span to accommodate maximum sag while keeping the line away from poles, trees, buildings, and other objects. For standard OSP span design, 1.4 meters is the typical requirement to ensure enough room under worst‑case sag conditions. A larger distance like 3.2 meters would add unnecessary right‑of‑way and cost, while smaller values such as 2.0 or 1.0 meter may not provide sufficient clearance in adverse conditions.
