Holding Strength.* Two models of AR Clamps have been tested for holding strength.
Alligator grip clamps slipped at a tensile
load of 1000 lbs. Nutcracker grip clamp slipped
at a tensile load of 1200 lbs.
and RIV Testing* AR Clamps and Spacer Dampers have been tested for
RIV measurements and corona photographs. RIV and Corona tests
AR Clamps are free of corona ad RIV well above 345kV.
Strength Testing.* AR Lightweight Spacer Dampers have been tested for
2200 lbs. in a series of tests including torque.
Insulator Rod Testing.* Insulator
rods used in the AR Spacer Twister have been tested for compressive strength to establish column-buckling behavior. The tensile test
of the 5/8” rod revealed an ultimate load of 35,000 lbs. The rods behave as an elastic column under compression load.
Galloping and Vibration Performance Testing.* AR Twister have been
tested to qualify for performance in controlling Aeolian vibration and galloping on energized high voltage transmission lines. Testing
also included corona and RIV.
Dynamic & Mechanical Testing.* AR Clamps,
Twister and Spacer Damper have been test for mechanical characteristics and tensile strength.
