The reactance value of an aluminum conductor depends on its length, cross-sectional area, and frequency of the alternating current passing through it. Generally, the reactance (X_L) for an inductor can be calculated using the formula (X_L = 2\pi f L), where (f) is the frequency and (L) is the inductance. For practical applications, the reactance of aluminum conductors is typically low, making them suitable for electrical transmission. However, specific values can vary based on the conductor's design and installation conditions.
When stranded conductor is being used for earthing, It offers some reactance in addition to the resistance of the conductor. Since any kind of surge is of sudden in nature, and reactance opposes the change in flow of current (Property of Inductor), It might disturb the discharge rate of the surge. Hence the conductor is flat inorder to provide only the resistance
when ever current passing through any two parallel transmission line than due to the dieletric property of conductor some what capacitance effect will be generate between them that phenomina called as capitance reactance/////////////////// that symply we can called capitance reactance is measure of capitance The reactance of a capacitor is its resistance.
ACSR stands for aluminum conductor, steel reinforced. This type of conductor is used for transmission lines that are strung between poles or towers. The aluminum is used for its lower resistance, and the steel provides the structural strength.
The resistance of an a.c. load is called 'resistance' (R). Resistance is not affected by frequency, only by the cross-sectional area, length, and resistivity of the conductor. Having said that, because of the skin effect, which causes an a.c. current to flow closer to the surface of the conductor, the effective cross-sectional are is reduced, so the value of a.c resistance is somewhat higher than the d.c. resistance -this difference increases with frequency.The opposition to a.c due to inductive or capacitive loads is called reactance (inductive reactance or capacitive reactance), and the overall opposition to a.c. current is the vector sum of resistance and reactance, and is called impedance. That is:(impedance)2 = (resistance)2 + (reactance)2
Reactance is -1/2 pi F C so a 25 uF capacitor at 400 Hz would have a reactance of about -15.9 ohms. The negative sign indicates that capacitive reactance is leading, with current leading voltage.AnswerI would take issue with the previous answer that capacitive reactance is expressed as a negative value, or that it is 'leading'. Reactance is not a vector quantity, so it neither leads nor lags anything. In a (theoretically) purely capacitive circuit, it is the load current that leads the supply voltage. However, when using complex notation, capacitive reactance is expressed as -j 15.9 ohms, where 'j' is called an 'operator' -but even this does not mean that the reactance is 'leading', as it defines reactance in terms of a current phasor -in other words, the '-j' refers to the relative position of current to voltage, not reactance to impedance.
No, the reactance of aluminum conductors is not the same as copper conductors. Aluminum has a higher resistivity than copper, which results in different reactance values for the two materials. The reactance of a conductor depends on its material properties and dimensions.
DC Resistance = 0.1362 Ohms/km Reactance depends upon line configuration and spacing
Yes, being a metal, aluminum is a good thermal conductor.

Yes, it is.
The ability of conductor to induce voltage in itself when the current changes is called inductive reactance.
No. Aluminum is an excellent conductor.
Aluminum is a conductor of thermal energy and electrical energy.
Copper and aluminum. Most heat sinks are made of Aluminum (cheap and a good conductor of heat).
Aluminum is a conductor of electricity. It has a relatively high conductivity compared to insulators like rubber or plastic.
Water is a poor conductor of electricity compared to aluminum, which is an excellent conductor. Aluminum has metallic properties that allow it to conduct electricity efficiently, while water's conductivity is primarily due to the presence of impurities and ions dissolved in it.
