The primary purpose of a 35KV high voltage cable is to transmit electrical power efficiently over long distances without significant energy losses. These losses can occur due to factors such as resistance, capacitance, and inductance, and they can reduce the overall efficiency of the transmission system. Therefore, the 35KV high voltage cable is used to ensure that electricity is transmitted over long distances with minimal losses, which helps to reduce energy costs for consumers.

How Does a 35KV High Voltage Cable Work?

A 35KV high voltage cable has several components, including a conductor, insulation, and an outer jacket. The conductor is usually made of copper or aluminum, an excellent conductor of electricity. The insulation is made of materials that resist electrical breakdown at high voltages, such as polyethylene, ethylene propylene rubber, or cross-linked polyethylene. The outer jacket protects the cable from external physical and environmental factors.

The electrical energy is transmitted through the conductor with the help of an electric field, which is created by the potential difference between the two ends of the cable. The insulation prevents the electric field from ionizing the air around the conductor, which can lead to electrical breakdown. This allows the cable to transmit electrical power over long distances without significant energy losses.
