Rope lay constructions using multiple “rope” strands, each “rope” strand is composed of multiple fine wires. Individual strands are made of soft drawn tinned copper wire.
Extra fexible stranded copper cables are also available in bare copper, (exchange “T” in the part number with the letter “B” ) terminated piece parts.
Approvals: individual strands Type R QQ-W-343
individual strands Type S ASTM-B-33 QQ-W-343
federal spec QQ-B-575 applies as indicated
Applications: grounding straps, vibration resistant un-insulated electrical connections, shunts.
For standard put ups in bulk quantity, 100 ft, 500 ft, 1,000 ft, please consult with sales department.
Ampacities shown are for bare conductors in free air with an ambient temperature of 85 degrees F.
