Complete Table of Three phase Cable Power Comparison 220V Abstract: The power comparison of three-phase cables is an essential aspect in the field of electrical engineering. This article aims to provide a comprehensive table comparing the power capabilities of different types of three-phase cables operating at 220V. The table will be divided into four aspects, each with detailed explanations and analysis. 1. Cable Type Comparison Three-phase cable systems are commonly used for transmitting electrical power efficiently and safely. In this section, we will compare the power capabilities of various cable types commonly used in three-phase systems.

1.1 Copper Cables

Copper cables are widely utilized due to their excellent conductivity properties. They have low resistance, which results in minimal energy loss during transmission. Copper cables can handle high-power loads efficiently and are suitable for long-distance applications.

Copper cables offer advantages such as high durability, flexibility, and resistance to corrosion.

They can carry heavy currents without significant voltage drops.

However, copper is relatively expensive compared to other materials.

1.2 Aluminum Cables

Aluminum cables are another popular choice for three-phase systems due to their cost-effectiveness and lightweight nature. While aluminum has higher resistivity than copper, it remains a viable option for medium-power applications.

The main advantage of aluminum cables is their lower cost compared to copper.

They also have good thermal conductivity properties.

However, aluminum has a higher coefficient of expansion than copper and may require additional precautions during installation.

1.3 Steel-Cored Aluminum Cables

Steel-cored aluminum (ACSR) cables combine the benefits of both steel and aluminum conductors. These composite conductors provide enhanced mechanical strength while maintaining acceptable electrical performance.

The steel core provides increased tensile strength without sacrificing conductivity efficiency.

This type of cable is commonly used in overhead transmission lines where both mechanical robustness and electrical performance are crucial factors.

2、Voltage Drop Comparison Voltage drop refers to the reduction in voltage that occurs when current flows through a conductor due to its inherent resistance or impedance characteristics.

2、 Voltage Drop Calculation Methodology

The voltage drop calculation method varies depending on factors such as cable length, load current magnitude, conductor material properties (resistivity), ambient temperature conditions (affecting resistivity), etc. A) Copper Cables: Copper has lower resistivity compared to other materials like aluminum or steel-cored conductors; hence it exhibits lower voltage drop characteristics under similar conditions. B) Aluminum Cables: Aluminum has higher resistivity than copper; therefore it tends to exhibit slightly higher voltage drops under identical conditions. C) Steel-Cored Aluminum Cables: Steel-cored aluminum (ACSR) conductors possess intermediate values between pure copper and pure aluminum regarding resistivity; thus they exhibit moderate levels of voltage drop based on similar parameters mentioned above.
