FAQ — Your Questions Answered
Q1: What does “zero buoyancy” mean in this cable?
Zero buoyancy means the cable’s overall density closely matches that of water, preventing it from floating up or sinking excessively, which reduces tension and drag on underwater systems.
Q2: Can this cable be tailored to specific lengths?
Yes. We offer custom lengths to match deployment distances and system layouts exactly.
Q3: Is the cable suitable for saltwater environments?
Absolutely — materials and jacketing are selected to resist salt corrosion and moisture penetration over long deployments.
Q4: What core configurations are available?
You can choose from 2, 4, 6 or 8 core versions to accommodate different power and communication needs.
Q5: How do I choose the right outer jacket?
PUR is typically chosen for excellent abrasion resistance, while TPE offers greater flexibility in cold environments. Contact us for help selecting the best solution for your application.
