What is the purpose of granular desiccants in cable insulation?

• A. To enhance conductivity
• B. To remove water
• C. To provide insulation
• D. To increase flexibility

Answer: (B)

Granular desiccants are materials specifically designed to absorb moisture from their surroundings. In the context of cable insulation, their primary purpose is to remove water, which is crucial for maintaining the integrity and performance of the insulation material. Excess moisture can lead to various issues such as deterioration of the insulation, increased risk of electrical faults, and reduced lifespan of the cable. By incorporating granular desiccants within the insulation, the overall reliability of the cable is enhanced, preventing water-related failures. This effectively ensures that the electrical properties of the cable remain stable and functional over time.
