In Article " Conductor Ampacity Calculation . For equipment 600 volts and under, the conductor size at the termination must be based on ampacities from Table 310.15(B)(16) because the selection of conductors based on a tables other than Table 310.15(B)(16), can result in overheated terminations at the equipment. .

If the ambient temperature differs from the ampacity tables' stated ambient temperatures (typically 30°C or 40°C) in NEC 2014 Article 310, a correction factor may need to be applied. NEC 2014 Table 310.15(B)(2)(A) Ambient Temperature Correction Factors Based on 30°C (86°F) is one of the tables where adjustment factors can be found.
The sag characteristics and the strength-to-weight ratio of the AAAC conductor cable is better than both AAC and ACSR. ACSR-ASTM-B Aluminium Conductor Steel Reinforced ACSR are available in a range of steel contents ranging from 6% to 40% for additional strength.
ACSR (Aluminium Conductor Steel Reinforced ) Aluminium Conductor Steel Reinforced (ACSR) is concentrically stranded conductor with one or more layers of hard drawn 1350-H19 aluminium wire on galvanized steel wire core. The core can be single wire or stranded depending on the size. Steel core wire is available in Class A, B or Class C .
For example, a 10 AWG 3C 600 V cable with XHHW singles would have an ampacity of 35 amps if using the 75°C column in NEC 2014 Table 310.15(B)(16) Allowable Ampacities of Insulated Conductors Rated Up to and Including 2000 Volts, 60°C through 90°C, Not More Than Three Current-Carrying Conductors in Raceway, Cable.

Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.The outer strands are high-purity aluminium, chosen for its good conductivity, low weight and low cost.The center strand is steel for additional strength to help support the weight of the conductor. . Steel is higher strength than aluminium which .
Nov 13, 2015· • Ambient temperature — Ampacity increases about 1% for each 1°C decrease in ambient temperature. • Wind speed — Even a small wind helps cool conductors significantly. With no wind, ampacities are significantly lower than with a 2-ft/ sec crosswind. Table 2.13 through Table 2.15 show ampacities of all-aluminum, ACSR, and copper .
5.1 The ACSR conductor shall be suitable for being installed directly in air supported on suspension insulator strings or anchored through tension insulator strings at the power cross arms of single circuit, double circuit or multi circuit transmission line towers.
ACSR – Aluminum Conductor Steel Reinforced Product Description Bare EC grade hard-drawn aluminum conductors stranded around an inner core of galvanized steel wire(s).
ACSR combines the light weight and good conductivity of 1350-H19 aluminum with the high tensile strength and ruggedness of steel. ACSR provides higher tension, less sag and longer span lengths than AAC and AAAC overhead conductors. Standard ACSR designs are manufactured with regular-strength Class A galvanized steel (/GA2).
The number of conductors is simply the service amperage divided by the desired wire size's ampacity rounded up if there is a remainder. Example: 1000A service, using 300kcmil conductors at 75 deg .
ACSR (aluminum conductor steel-reinforced) has a long service record because of its economy, dependability, and strength to weight ratio. The combined light weight and high conductivity of aluminum with strength of the steel core enables higher tensions, less sag, and longer spans than any alternative. .
