Armored power cables are widely used in power transmission and distribution. They feature a metal armor surrounding the insulation for additional protection and electromagnetic shielding. Below are some common armored power cable types and their applications:
1. XLPE Armored Cable:
Application: XLPE (cross-linked polyethylene) armored cables are commonly used in medium- and high-voltage power transmission and distribution systems. They are widely used in underground installations, indoor and outdoor installations, and in cable trenches. These cables offer high dielectric strength and electrical performance, making them suitable for power networks requiring high reliability.
2. PVC Armored Cable:
Application: PVC (polyvinyl chloride) armored cables are commonly used in low-voltage power transmission and distribution systems, such as those in residential, commercial, and industrial applications. They are suitable for indoor installations and perform well in dry environments. These cables are relatively low-cost and suitable for applications with limited financial resources.
3. Aluminum Armored Cable:
Application: Aluminum armored cables feature an aluminum metal armor and are commonly used for medium-voltage power transmission. They are suitable for a variety of applications, including underground cable trenches, cable tunnels, and overhead lines. Aluminum-armored cables are generally lighter and less expensive than copper-armored cables, but the electrical conductivity of the aluminum material must be considered.
4. High-Temperature Armored Cables:
Application: High-temperature armored cables are designed for use in high-temperature environments, such as industrial applications like power plants, metallurgy, and refineries. They offer excellent heat resistance and insulation properties, enabling stable operation in extreme temperature conditions.
5. Flame-Retardant Armored Cables:
Application: Flame-retardant armored cables are typically used in applications requiring fire resistance and low smoke and toxicity, such as subways, airports, hospitals, and large commercial buildings. They reduce the generation of hazardous gases and smoke in fire situations, improving evacuation safety.
6. Oil-Immersed Armored Cables:
Application: Oil-Immersed Armored Cables are typically used in substations and transformers. They are used in oil-filled equipment to transmit power and protect transformers.
