Black PUR jacket shielded 7-core underwater cable for ROV power and control. Individually shielded conductors for reliable multi-channel ROV control and power in a single cable.
The shielded 7-core black PUR underwater cable provides seven independently insulated and shielded conductors for multi-channel ROV power distribution and control signal transmission. The black PUR jacket gives this cable a clean, professional appearance and excellent resistance to UV, oil, and abrasion in topside and splash-zone sections of the tether system. With seven cores, the cable typically carries thruster power (1-2 cores), electronics power (1-2 cores), RS-485 control (2 cores), and a spare core.

Seven cores is a common standard for small to medium observation ROVs: 2 cores for main DC power (+ and -), 2 cores for RS-485 control bus (A and B), 2 cores for lighting power (+ and -), 1 spare core for future expansion or sensor. This allocation provides the essential functions of power, communication, and lighting in a compact cable.
For power-supply cables, the shield is typically earthed at the topside end only (single-point earthing) to avoid ground loops. For signal cables, earthing practice depends on the signal type -- RS-485 uses single-point earthing. Consult your ROV system integrator for the recommended earthing configuration.
