The cross arm brace purpose on overhead distribution lines is straightforward but non-negotiable — it stops the cross arm from twisting, bending, or shearing off the pole under combined wind, wire tension, and equipment weight. Without proper bracing, a single storm or ice event can trigger a cascade failure across multiple spans. At RaxPower, we…
Assuming composite crossarms are immune to lightning is a mistake that creates catastrophic failures in extreme weather. Effective crossarm lightning protection requires a precise understanding of surge current behavior. At RaxPower, our field data confirms that installing metal rods at the highest point provides a low-resistance path, safely diverting current away from the structural core…
Cross arms break before the pole does. That’s not a theory — it’s a pattern we’ve seen across thousands of installations, and more often than not, it traces back to improper brace mounting. Cross arm brace installation isn’t just about bolting steel to wood or composite. A brace mounted off-center, with washers not seated straight,…
A cross plate anchor is a heavy-duty subsurface anchoring assembly fabricated from two corrugated structural carbon steel plates welded in a cross formation — designed specifically for high-tension utility pole line guying and transmission tower guy anchoring. Forged from high-yield structural steel conforming to ASTM A36 or ASTM A572 Grade 50, the cross-ribbed plate design…
