(1) Equivalent ACSR Size refers to an ACSR conductor size of equal diameter.                                                                            
(2) Equivalent ASC Size refers to an ASC (i.e., CSA C61089 A1) conductor of approximate equivalent electrical resistance.                                                                                
Dimensions and weights not designated minimum or maximum are nominal values and subject to manufacturing tolerances_  In this context. weight means mass

(3) Based on a conductivity of 53.0% IACS at 20˚C for aluminum.
(4) Based on a conductor temperature of 75°C at 60 Hz and the following conditions, 32°C ambient temperature, 1.98 ft/sec (0.6 m/sec) crosswind (90° to conductor), 0.5 coefficient
of emissivity for a standard conductor and 0.9 for a E3X coated conductor, 0.5 coefficient of absorptivity for a standard conductor and 0.2 for a E3X coated conductor, 42° northern
 latitude, sea level elevation, 90° azimuth of line (East-West), clear atmosphere, and a date and time of noon on July 1 (resulting in 95.0 W/ft² of solar and sky radiated heat). 
Actual ampacity will differ based on local conditions. For specific ampacities, please contact your MVA Power sales representative.                                                                            
(5) Values for inductive reactance and capacitive reactance are expressed in terms of a 1 ft radius (30.48 cm).
