Aluminum Trunnion Suspension Clamp
The Trunnion suspension clamp is a heavy-duty overhead line fitting designed to support and suspend conductors from transmission and distribution line structures while allowing limited conductor movement under mechanical loading. Its trunnion-mounted design minimizes stress concentrations, reduces conductor wear, and accommodates angular displacement caused by wind, temperature variations, and line vibration. Manufactured from high-strength, corrosion-resistant materials, the clamp provides reliable mechanical performance and long-term durability in demanding outdoor environments.
