Worldwide High-voltage cables and accessories Market will grow at a CAGR of 7.2% throughout the predicted period (2022 - 2030).

High Voltage Cables for Electric Vehicles

Electric vehicles (EVs) use high voltage batteries to power their electric motors. These batteries are connected to the motor through high voltage cables. The high voltage cables used in EVs are designed to withstand high temperatures and provide reliable power transmission. These cables are typically made using XLPE insulation materials, which have excellent electrical properties and can withstand high temperatures.

High Voltage Cable Insulation Materials

High voltage cables are insulated to prevent electrical breakdown and ensure the safe and reliable operation of the cable.

Types of High Voltage Cables

There are different types of high voltage cables, each designed for specific applications. Some of the most common types include:

1. XLPE Cables: XLPE (Cross-linked Polyethylene) cables are widely used in power transmission and distribution systems. These cables have excellent electrical properties and are suitable for use in both AC and DC systems.
2. Oil-Filled Cables: Oil-filled cables are used in applications where XLPE cables cannot be used due to their limitations. These cables are filled with oil, which helps to dissipate heat and reduces the risk of electrical breakdown.
3. SF6 Gas-Insulated Cables: SF6 (Sulfur Hexafluoride) gas-insulated cables are used in high voltage applications where space is limited. These cables have high dielectric strength and can transmit large amounts of power over long distances.
4. Paper-Insulated Lead-Covered Cables: Paper-insulated lead-covered cables are used in applications where XLPE and oil-filled cables cannot be used due to their limitations. These cables are designed to withstand high temperatures and are suitable for use in high voltage DC systems.
