Its 4-layer construction comprises coaxial center conductor, low-loss coaxial dielectric & braid shield and double torque-balanced steel wire armour.

What is the minimum bending radius and operating temperature range for Netsonde CB 6000/7000 Armored?

The minimum bending radius for Netsonde CB 6000/7000 Armored is 12 × OD across its continuous operating temperature range of -40 to +80 °C, ensuring mechanical flex endurance and hydrostatic reliability in subsea winches, TMS cages and aquaculture installations.

How are the concentric layers of Netsonde CB 6000/7000 Armored arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Coaxial Center Conductor — High-conductivity stranded copper (or steel-core on CB 1900) center conductor; (02) Low-Loss Coaxial Dielectric & Braid Shield — High-density polyethylene (HDPE / PE) core insulation + braided copper outer conductor; (03) Copper Wire Braid EMC Screen — High-coverage braided copper shield for EMI/VFD protection; (04) Double Torque-Balanced Steel Wire Armour — Contra-helical high-tensile galvanized steel wire armour.

What factory test certificates are supplied with Netsonde CB 6000/7000 Armored?

Every production drum of Netsonde CB 6000/7000 Armored undergoes routine conductor DC resistance / optical OTDR continuity, AC high-voltage dielectric and dimensional testing per DNV Subsea Netsonde CB 6000/7000 Double-Armored Trawl Sonar Specification, and is delivered with an EN 10204 3.1 factory test certificate.
