Bitumen in Cable Manufacturing: Types, Applications, and Benefits
Bitumen in Cable Manufacturing plays a critical role in protecting power and communication cables through moisture sealing, thermal stability, and long-term insulation performance. Modern industrial applications rely on specialized oxidized and penetration-grade bitumen to prevent corrosion, extend cable life, and reinforce mechanical strength in harsh environments. From paper-insulated lead-covered (PILC) networks to low-voltage power distribution joints, bitumen remains essential in both legacy infrastructure maintenance and new energy projects. This article explores practical types of bitumen used in cable systems, how they are applied in joints and sheath protection, and why choosing the right grade directly impacts safety and service reliability. It also answers common technical questions from engineers, procurement teams, and maintenance professionals, offering selection guidance, field best practices, and performance considerations backed by standards.
