Extreme Environment Solutions

1.What is the difference between Waterproof Cables and Submarine Cables?

Waterproof Cables: Designed for damp, submerged, or localized high-pressure environments (e.g., ROVs, underwater cameras, pool sensors). They focus on IP68 sealing and flexibility.
Submarine Cables: Massive, heavily armored infrastructure cables used for long-distance seabed power and telecommunication transmission between landmasses.

2. How do you prevent ROV cable water leakage after repeated dynamic movement?

We implement a robust "Radial + Axial" sealing strategy:

Radial: Hot melt adhesive paired with semi-conductive water-blocking tape (≥300% expansion).
Axial: Butyl rubber sealing paste filling conductor gaps, wrapped in steel tape armor.
Dynamic Connectors: O-ring (fluororubber) + wedge seals with a precisely controlled 20-30% compression rate.

3. How do zero-buoyancy ROV cables maintain exact buoyancy (±3%)?

We use precise material and structural calculations:

Extrude low-density PE foamed sheaths (controlling nitrogen injection).
Embed hollow glass microspheres (density 0.2g/cm³) into the cable core.
Strictly calculate the buoyancy-to-mass ratio and verify via 24-hour water tank suspension tests.

4. What makes Nuclear Fusion Cables unique?

Used in tokamak devices, these highly specialized superconducting cables transmit power for massive magnetic confinement systems. They must withstand extreme neutron radiation and high temperatures without degrading.

5. How do you improve the radiation resistance of nuclear cables?

Insulation: Irradiation-crosslinked PE (XLPE) combined with a high-purity mica tape composite (radiation resistance ≥2000kGy).
Conductor: Nickel-based alloys (Inconel 600) with a 5μm nickel coating to prevent oxidation.
Jacket: PEEK material for exceptional strength retention post-radiation.
