GMR = Geometric Mean Radius. D s1, D s2, D s3, D s4, D s5, D s6, D s7 are individual strand GMR. r = radius of strand. Find GMR of Two Layer ACSR Calculator at CalcTown. Use our free online app GMR of Two Layer ACSR Calculator to determine all important calculations with parameters and constants.

ACSR – Aluminum Conductor Steel Reinforced is used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding for desired strength to be achieved without sacrificing ampacity. CONDUCTORS: • Aluminum alloy 1350-H119 wires, concentrically ...

2009年7月20日 · Geometric Mean Radius [GMR]: There are magnetic flux lines not only outside of the conductor, but also inside. GMR is a hypothetical radius that replaces the actual conductor with a hollow conductor of radius equal to GMR such that the self inductance of the inductor remains the same. The GMR is given by manufacturer’s tables.
