2x2.5mm2 + 1x2x0.5mm2 Power/Signal Underwater Cable | ROV Subsea

2x2.5mm2 power conductors + 1x2x0.5mm2 twisted signal pair underwater cable. PUR jacket, seawater resistant, for ROV power and control signal transmission.

Product introduction

2x2.5mm2 + 1x2x0.5mm2 Underwater Power/Signal Cable for ROV Systems

This hybrid underwater cable combines two 2.5mm2 power conductors with a 1 x 2 x 0.5mm2 shielded signal pair in a single PUR-jacketed cable. Designed for ROV and subsea equipment applications where both power delivery and control signal transmission must coexist in a compact, seawater-resistant cable assembly.

Frequently Asked Questions

What current can the 2.5mm2 conductors carry?

In air, 2.5mm2 conductors typically carry 16--20A. Underwater with PUR jacket and good heat dissipation, derated values of 14--18A are typical. Always apply the relevant derating factor for your specific installation conditions and depth.

Is the signal pair protected from power conductor interference?

Yes. The 0.5mm2 signal pair is individually foil and braid shielded, providing effective isolation from the power conductors. This prevents EMI/RFI coupling and ensures clean control signal transmission.
