Model of three-phase four wire cable Abstract: The model of three-phase four wire cable is an essential component in the field of electrical engineering. This article aims to provide a detailed explanation of this model from four aspects: structure, function, advantages, and applications. 1. Structure The structure of the three-phase four wire cable consists of three conductors and one neutral conductor. These conductors are insulated with high-quality materials to ensure safety and prevent any leakage or short circuits. The neutral conductor is connected to the ground for protection against overvoltages. The first conductor carries phase A current, while the second conductor carries phase B current, and the third conductor carries phase C current. These currents are usually balanced to ensure equal distribution across all phases. 2. Function The primary function of the three-phase four wire cable is to transmit electrical power efficiently and safely in industrial and commercial settings. It provides a reliable connection between power sources such as generators or transformers and various loads like motors, lighting systems, or appliances. By using a combination of multiple phases with a neutral conductor, this model allows for efficient power transmission without significant voltage drops or imbalances. It ensures that each load receives sufficient power while maintaining stability in the overall electrical system. 3. Advantages One major advantage of using a three-phase four wire cable is its ability to handle higher loads compared to single-phase cables. The balanced distribution across all phases minimizes voltage drops during transmission, resulting in more efficient energy transfer. Additionally, this model offers better fault tolerance due to its grounding system through the neutral conductor. In case there is an insulation failure or short circuit on one phase line, it reduces potential damage by providing an alternate path for fault currents through grounding instead of flowing into equipment or causing electric shocks. Furthermore, using multiple phases enables smoother operation for certain types of loads like motors that require rotating magnetic fields generated by alternating currents from different phases simultaneously. 4.Applications The versatility offered by the model makes it suitable for various applications across different industries:

1) Industrial Power Distribution

In industrial settings where heavy machinery operates continuously, the use of a three-phase four-wire cable ensures stable power supply to meet high demand requirements.

It allows seamless integration with motor-driven equipment such as conveyors, compressors, and pumps.

2) Commercial Buildings

In commercial buildings like shopping malls, office complexes, or hospitals, the installation
