1. Calculation method and influencing factors of current carrying capacity of high-voltage cables. The calculation method of current carrying capacity of high-voltage cables is mainly based on factors such as conductor cross-section, resistivity, temperature coefficient, etc. The influencing factors include cable material, length, working environment temperature, etc. Calculation method Yushu Qiao: Based on conductor cross-section: The current carrying capacity of a cable is directly proportional to the conductor cross-section, that is, the larger the conductor cross-section, the greater the current carrying capacity. The calculation formula is Q=K × It, where Q is the current carrying capacity, K is the cross-sectional area coefficient of the conductor, and It is the cross-sectional area of the conductor. Consider resistivity: The resistivity of a cable directly affects its current carrying capacity, and the smaller the resistivity, the greater the current carrying capacity. The resistivity is affected by factors such as cable material and temperature. Combined with the key temperature coefficient calculation: The current carrying capacity of the cable varies with temperature, and the temperature coefficient is generally used to correct the calculated value. At higher temperatures, the current carrying capacity of the cable will decrease. Influencing factors: Cable materials: Cables made of different materials have different electrical and thermal properties, which affect their current carrying capacity. Cable length: The length of a cable can affect its resistance and heat dissipation performance, thereby affecting its current carrying capacity. Longer cables may experience a decrease in current carrying capacity due to increased resistance and difficulty in heat dissipation. Working environment temperature: The temperature of the environment in which the cable is located has a significant impact on its current carrying capacity. In high temperature environments, the current carrying capacity of cables may decrease. Other factors such as cable installation and laying methods can also affect the current carrying capacity. For example, good heat dissipation conditions and appropriate laying tension can increase the current carrying capacity of hand silver.

2.10KV, How much load can a 300 square meter high-voltage cable withstand? How to calculate?

1. The load calculation of high-voltage cables needs to consider the cross-sectional area and rated current of the cable. For a 300 square millimeter high-voltage cable, the working current it can withstand is approximately 450 amperes. To calculate the load that a 300 square millimeter cable can withstand at 10 kilovolts (10KV), we can use the power formula: P=√ 3 × U × I, where P is the load power (in kilovolt amperes (KVA)), U is the rated voltage of the cable (in kilovolts (KV)), and I is the rated current of the cable (in amperes (A)). The rated voltage of the cable should match the system voltage and operating conditions of the cable being used. A 10kV rated cable should be selected for a voltage environment of 10KV. The rated voltage of the cable is generally represented by U0/U (Um): U0 is the rated power frequency voltage between the conductor and the ground or between the metal and the hand shield, that is, the phase voltage; U is the rated power frequency voltage between conductors, that is, the line voltage; Um is the maximum system voltage that the equipment ca
