21 conductors 20AWG subsea polyurethane cable. High conductor count for complex ROV umbilicals requiring many independent signal and control channels.
With 21 x 20AWG conductors in a single PUR-jacketed cable, this high-core-count subsea cable addresses the most complex ROV and subsea system requirements -- providing up to 21 independent signal and power channels for multi-thruster ROVs, manipulator arms, sonar systems, sensor suites, and navigation instruments, all in a single drag-minimising cable assembly.

For complex 21-core umbilical specifications and custom design: sales@rovcable.com -- Shanghai Kabel Intelligence Technology Co., Ltd.
We apply a 21-colour/number identification scheme: cores are colour-coded in groups of 5--7 (using tracer stripes on the insulation) and numbered with sequential print, making identification unambiguous even in large-diameter multi-core cables.
A 21 x 20AWG PUR cable typically has an OD of 20--28 mm depending on shielding and jacket thickness. We optimise the OD for minimum drag while maintaining mechanical protection. Confirm the OD during the design review when ordering.
