Typical Design
Key Features
- Hybrid Cable Design: Superior signal strength with excellent resistance to water pressure and mechanical compression while maintaining high quality connectivity and dynamic strength
- Buoyancy Optimization: Custom density calculations for fresh or salt water, warm or cold water environments
- Comprehensive Water Sealing: Multiple waterproofing options to prevent water entry and longitudinal water transport
- Advanced ROV Cable Engineering:
- Fiber optic, CAT or coaxial cable for high-speed data transmission
- Triple extruded conductor with low to medium voltage and high current capacity
- Thin wall design with lightweight, waterproof materials for compact size, high reliability and long service life
- Aramid braid and rope for superior torsional and tensile strength, minimizing strain and stress
- Screened and armored construction optimized for required performance
Performance Characteristics
Special flexible sheath material (customer-selectable colors) provides exceptional bending life exceeding 6 million cycles without sheath breakage. Cable features excellent flexibility, wear resistance, oil resistance, acid and alkali resistance, tensile strength, waterproof properties, and anti-aging performance. Designed with specific gravity infinitely close to water for optimal floating capability.
