DEADENDS
BOLTED
QUADRANT STRAIN CLAMP
ALUMINUM
ALUMINUM
AR1/AR2

These clamps are used primarily for deadending aluminum substation cable bus.

During installation the cable will slide free under the U-bolts, or if preferred, U-bolts may be removed and cable laid in clamp grooves from the side.

These clamps are compact for greatest phase clearance.

Material: Body and Keeper—356-T6 aluminum alloy
Hardware—galvanized steel
Sockets and Clevises—ductile iron, galvanized
Cotter Pin—#302 stainless steel

NOTES:
  • (1) Sag Eye Ultimate Strength is 60% of Clamp strength without fitting.
  • (2) Rated slip strength as a % of conductor RBS varies with conductor type, size and stranding.
    Minimum slip strength rating on standard strength conductors is 40% RBS (Partial Tension).
    For many standard strength conductors, mininum slip strength of this clamp series is 60% RBS (Normal Tension).
    (Consult factory for slip strength test data on specific clamp & conductor combinations.)
  • (3) Recommended torque on u-bolts: 3/8" -- 240 in-lbs., 1/2" -- 480 in-lbs.
  • (4) Bolt and Nut may be substituted for clevis pin by adding suffix "BNK" to catalog number.
