NOTE: Sag eye ultimate strength is 60% of clamp strength without fitting. Rated slip strength as a percentage of conductor RBS varies with conductor type, size and stranding. Minimum slip strength rating on standard strength conductors is 40% RBS (partial tension). For most standard strength conductors, minimum slip strength of this clamp series is 60% RBS (normal tension). Consult factory for slip strength test data on specific clamp and conductor combinations. Recommended torque on U-bolts: 1” — 480 in-lb, 5/8 ” — 720 in-lb. Bolt and nut may be substituted for clevis pin by adding suffix “BNK” to catalog number. For corona-free applications on EHV lines, add suffix “CRF” to catalog number. Example SD130NCRF.
