@sunj.zhejiang: Same Mechanical Lug. Why Is One Hole Centered and the Other Eccentric? Same Mechanical Lug. Different bore position. Why? It is not just an appearance change. The bore centerline moves relative to the lug body. That can change the bore wall distribution, the conductor entry position, and the bolt-to-conductor relationship. So do not choose a Shear Bolt Lug by bore diameter alone. Do not rely only on nominal cross-section either. Check three things: 1. Conductor structure 2. Actual outer diameter 3. Center-hole or eccentric-hole design Match the actual conductor—not just the number on the cable.#SUNJ #MechanicalLugs #ShearBoltLug #CenterHole #EccentricHole #CableLug #CableAccessories #ConductorSelection #ElectricalEngineering #CableInstallation #PowerCable #B2BManufacturing
