ACSR conductors -Volume of conductor required for various systems of transmission-Choice of transmission voltage, conductor size -Kelvin's law. Mechanical Characteristics of transmission lines – configuration-Types of Towers. Calculation of sag and tension- supports at equal and unequal heights -effect of wind and ice- sag template ACSR conductors are recognized for their record of economy, dependability and favorable strength/weight ratio. ACSR conductors combine the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel. In line design, this can provide higher tensions, less sag and longer span lengths than obtainable

Coefficients for new conductors are also calculated using known coefficients originating from third parties, such as The Aluminum Association and ALCOA, and standard or conventional stress-strain-creep (S-S-C) charts. This feature makes it faster and simpler to analyze new conductors. Stress-Strain Properties

Triplex wire is constructed with two aluminum conductors that are designed to handle a maximum of 600 volts. It also features a black extruded cross-linked polyethylene insulation, which can protect the cable from temperatures as high as 90°C.

It is critical that utility personnel apply the appropriate tension to overhead conductors. Too little tension and the sag of the line can be excessive. Too much tension and the conductor can snap in cold weather. Once initially set, the tension of the conductor is determined by creep and by line temperature.

- Tradingview resolution inputACSR cable is especially suitable for line design due to its steel core strand, which increases the strength of the cable without sacrificing its ampacity, yet affects the ACSR wire price. The aluminum alloy conductor in ACSR wire prevents overheating and allows for extra flexibility of the electrical wire.
