1277 MCM 1350-H19 54 Str 6201-T81 7 Str Bunting ACAR Aluminum Conductor Aluminum Reinforced

1277 MCM 1350-H19 54 Str 6201-T81 7 Str Bunting ACAR Aluminum Conductor Aluminum Reinforced

Application:

ACAR concentric-lay-stranded conductors in single and multi-layer conductor designs to optimize the strength and the current carrying capacity for transmission and distribution projects for which AAC conductors do not provide the required strength and AAAC or ACSR conductors are either not required or suitable

Also Known As:

1277 MCM ACAR Aluminum Cable, Aluminum Reinforced Cable, 1277 MCM Stranded Lay Cable, 1277 MCM ACAR Cable, Aluminum Bare Concentric Cable, 1277 MCM ACAR Stranded Conductors.

Features:

The high strength to weight ratio provided by the 6201-T81alloy makes ACAR conductors a preferred choice for transmission and distribution projects where:
• conductor with more strength than AAC is required
• conductor with high current capability is preferred over ACSR or AAAC
• conductor with lower weight than ACSR is desired
• conductor with higher corrosion resistance than ACSR is essential.

Construction:

• ACAR is a concentric-lay stranded conductor made from round aluminum 1350-H19 (extra hard) wires and round aluminum 6201-T81 wires. ACAR conductors are available in single and multi-layer constructions. These choices provide the necessary strength and the current carrying capacity for given applications. For equal weight, ACAR conductors offer higher strength and ampacity than ACSR conductors.
• Typically, 1350-H19 wires are stranded around a core of 6201- T81 wires. However, in some designs 1350-H19 and 6201-T81 wires are stranded in the same layer.
• ACAR conductors are manufactured in accordance with the ASTM specifications B230, B398 and B524.
