3 pairs 22AWG + 1 pair 18AWG shielded twisted pair underwater cable. PUR jacket, mixed-gauge for combining low and high-power signal channels in ROV subsea systems.
This mixed-gauge underwater signal cable combines 3 x 22AWG shielded twisted pairs for low-power signal channels with 1 x 18AWG shielded twisted pair for higher-current or lower-impedance signal needs. Enclosed in a PUR jacket, it is designed for ROV and subsea systems where different signal types -- sensor data, control commands, and power signals -- must share a single cable run.
| Parameter | Specification |
|---|---|
| Light Signal Pairs | 3 x 2 x 22AWG (individually shielded) |
| Heavy Signal Pair | 1 x 2 x 18AWG (shielded) |
| Jacket Material | Polyurethane (PUR) |
| Voltage Rating | 300V RMS |
| Temperature Range | -30°C to +80°C |
| Depth Rating | Up to 4,000 m |
| Overall Shield | Foil + braid |

This configuration is ideal when most signal channels are low-power (22AWG is sufficient for RS-485, 4--20mA, or low-voltage analogue), while one channel requires higher current capacity or lower resistance -- for example, a solenoid valve pilot signal or a motor brake release pair. Combining them in one cable reduces the total number of cable runs needed.
The overall braid/foil shield is a separate layer from the individual pair shields. Individual pair shields are typically connected at one end only (single-end grounding) to avoid ground loops, while the overall shield is grounded at the control unit end for maximum EMI rejection.
