UV-resistant jackets are commonly used in outdoor power cables to enhance durability and longevity.
4. Temperature Rating:
Outdoor power cables are rated for a specific temperature range to ensure safe operation in outdoor environments. The temperature rating of the cable determines its ability to withstand high or low temperatures without compromising performance. It is essential to select outdoor power cables with temperature ratings suitable for the ambient conditions of the installation site.
5. Flexibility and Durability:
Outdoor power cables are designed to be flexible and durable to withstand bending, twisting, and rough handling in outdoor applications. Flexible cables are easier to install and maneuver in tight spaces, while durable cables can resist mechanical stress and maintain electrical integrity under harsh conditions. The flexibility and durability of outdoor power cables contribute to their overall reliability and longevity.
Applications of Outdoor Power Cables:
Outdoor power cables are used in a wide range of applications across various industries and settings. Some common applications of outdoor power cables include:
