Product Construction:
Complete Conductor:
The TransPowr™ ACCC/TW is a marriage of General
Cable’s TransPowr ACSS/TW technology and CTC
Cable Corporation’s pultruded composite technology.
Together these two technologies create the
transmission and distribution conductor of the future.
TransPowr ACCC/TW is a Trapezoidal Aluminum
Conductor Composite Core Concentric-Lay-Stranded
conductor. The aluminum strands are trapezoidal in
shape allowing for a more compact placement of the
aluminum strand wires. TransPowr ACCC/TW
conductors are designed to maintain the same overall diameter as a conventional round wire ACSR or ACSS conductor. The compact
trapezoidal conductors, coupled with a smaller composite core, result in a TW conductor that has approximately 28% more aluminum
cross-sectional area than ACSR or ACSS conductors. The greater aluminum content, combined with the capability to work at high operating
temperatures, can double the current carrying capacity of an existing transmission line.
The central strength member component of the TransPowr ACCC/TW conductor is a proprietary high-strength carbon and glass fiber
composite core patented by CTC Cable Corporation, around which are stranded two, three or four layers of annealed 1350 aluminum alloy
wires. The annealed aluminum strand wires of the TransPowr ACCC/TW conductors are manufactured in accordance with the requirements of
the latest issue of ASTM B857/ASTM B609 specification.
The TransPowr ACCC/TW conductor is designed to match the overall diameter of an existing concentric round ACSR or ACSS conductor.
Because the TransPowr ACCC/TW conductor is so new, there is as yet no unique code word names assigned to these conductors. Consequently,
the TransPowr ACCC/TW conductor has adopted the code word name of the original ACSR or ACSS conductor with the same matching
overall diameter.
Performance
The TransPowr ACCC/TW conductor is superior to existing bare overhead conductors such as concentric round ACSR and ACSS in a number
of key performance areas — capacity, sag, line losses and support structures. These performance advantages, that quickly and cost-effectively
increase the ampacity of existing transmission and distribution lines, proactively address the problems plaguing the utility market, offering
significant benefits to electric utility companies and ultimately to their industrial, commercial and residential customers.
Features and Benefits
In comparison to conventional concentric round ACSR conductors, and in some aspects to ACSS conductors, TransPowr ACCC/TW conductors
additionally have some very important key features and benefits. For example: a) Compared to ACSR, the TransPowr ACCC/TW conductor can
be operated continuously at high temperatures—175°C without damage, and at 200°C for short-term durations; b) Compared to ACSR, ACSS and
any other steel-cored conductors, the TransPowr ACCC/TW composite core material has a very low thermal expansion coefficient. At
elevated temperatures, the composite core material determines the sag characteristics of the conductor; c) The TransPowr ACCC/TW
conductor is not affected by long-term creep of the aluminum; d) The overall mass (weight) of the TransPowr ACCC/TW conductor, even with
the increased aluminum content, can be lighter than the original ASCR or ACSS conductor it is replacing; e) The annealed aluminum strand
wires in the TransPowr ACCC/TW conductor have self-damping properties which may eliminate the need for dampers and other antivibration
devices; and f) TransPowr ACCC/TW’s composite core material will not rust or corrode like existing zinc or zinc-5% aluminum
mischmetal coated steel materials.
Applications:
TransPowr ACCC/TW conductors have been specifically designed for overhead power distribution and transmission lines.
