2. Type: HDGYG-(3×6.0+1×2.5+2×1B1) /300
3. Cable design
1. Cable d'alimentació
1.1 Conductor: use stranded copper wire, 4 wires (3 wires of 6.0mm2, 1 wire of 2.5mm2).
1.2 Insulation: made of compound insulation, special high temperature resistant material, heat resistance≥120℃.
2. Cabling: refer to the figure.
3. Sheath: polyethylene, nominal outer diameter :18.0mm.
4. Reinforced layer: reinforce by steel wire double-layer reverse stranding with high strength.
5. Cable nominal outer diameter: 25.0mm.
• Main applications
This cable is used for power supply and signal transmission of underwater equipment in the ocean, can be dragged, can be winded for unwinded repeatedly.
• Working condition
1. Working ambient temperature: -20℃~+80℃;
2. The minimum allowable bending radius for installation is 10 times of the cable outer diameter;
