Performance Requirements for Undersea Telecommunications

Vulcanized tubing plays a critical role in the performance and reliability of undersea telecommunications systems, where cables are exposed to harsh environmental conditions and demanding operational requirements. As of 2025, the performance requirements for these materials have become increasingly stringent, reflecting both advances in cable technology and the growing importance of global data connectivity.

Undersea telecommunications cables must endure high hydrostatic pressures, extreme temperature variations, and potential mechanical impacts along the seabed. Vulcanized tubing—typically composed of cross-linked elastomers such as ethylene propylene rubber (EPR) or silicone—serves as protective insulation and jacketing to prevent water ingress, electrical faults, and corrosion. Major manufacturers such as www.prysmiangroup.com and www.nexans.com specify that their undersea cable products utilize vulcanized tubing rated for pressure resistance exceeding 8000 psi, and for operational lifespans of 25 years or more.

Key performance metrics for vulcanized tubing in this context include:

• Waterproofing: Tubing must exhibit extremely low water permeability to ensure no ingress over decades, verified via accelerated aging and pressure vessel testing (www.nexans.com).
• Electrical Insulation: Dielectric strength remains a primary requirement, with tubing needing to withstand breakdown voltages above 20 kV/mm, as documented by www.prysmiangroup.com.
• Mechanical Durability: Resistance to abrasion, impact, and cyclic flexing is essential, especially during laying and recovery operations. www.nkt.com highlights enhanced mechanical testing protocols for their vulcanized tubing assemblies.
• Chemical Resistance: Protection against marine biofouling, saltwater, and hydrocarbon exposure is vital for long-term reliability.
