Applications
TP Conductor bare aluminum construction, is designed for use in overhead applications subject to Aeolian vibration and galloping due to wind and ice. TP Conductor can be strung to the maximum allowable tension limits without the need for additional vibration protection.

Construction
TP Conductor is composed of two identical bare conductors twisted together with a left-hand lay. This gives the cable a rectangular spiral shape. This spiral shape disrupts the forces created by steady cross winds which cause cable vibration, by presenting a continuously changing projected cable diameter to the wind. This spiral shape, together with less torsional stiffness and varying bending stiffness also reduces or eliminates cable galloping due to combined ice and wind loads.

The component conducts of TP can be conductor types AAC, AAAC, ACAR, ACSR, AAC/TW or ACSR/TW meeting the requirements of the appropriate ASTM standards.

Specifications
TP Conductor meets or exceeds the following ASTM specifications for the sub-conductor of each assembly :

B-911/B-911M For Twisted Pair Conductor.
B-231 Aluminum Conductor, Concentric-Lay Stranded.
B-232 Aluminum Conductor, Concentric-Lay Stranded, Coated Steel Reinforced (ACSR).
B-399 Concentric-Lay Stranded 6201-T81 Aluminum Alloy Conductors.
B-524 Concentric-Lay Stranded Aluminum Conductors, Aluminum Alloy Reinforced (ACAR, 1350/6201)
B-779 Shaped Wire Compact Concentric-Lay Stranded Aluminum Conductors, Steel Reinforced (ACSR/TW.)

Ampacity calculated assuming: conductor temperature of 75^oC, ambient temperature of 25^oC, emissivity 0.5, wind 2ft/sec...in sun.
