H3: 2. Stable 75Ω Coaxial Video Transmission Structure

The core coaxial unit strictly controls impedance ±2Ω, double-layer copper shielding design, low signal attenuation, no image ripple, clearly transmit analog CCTV, HD 1080P, 3G-SDI digital video signals, guarantee real-time high-definition image return of underwater cameras at 50–3000m working depth.

H3: 3. Integrated Tensile & Water Blocking Construction

Internal full water-blocking tape + water-blocking yarn block longitudinal seawater penetration; embedded high-strength Kevlar aramid braided tensile layer, bear large pulling force during cable retraction, avoid core breaking under dynamic dragging. For ultra-deep sea projects, we support customized steel wire armored structure for anti-extrusion protection.

H3: 4. Customizable Composite Cable Layout

As a professional China underwater PUR coaxial camera cable factory, we support free matching of:
  • Single/multiple 75Ω coaxial video cores

  • 2–12 core power supply conductors

  • RS485 / control signal twisted pairs

  • Zero-density buoyant filling (optional neutrally buoyant cable for light ROV)

    Custom outer diameter, length, connector assembly (subsea waterproof camera connector) according to client project parameters.

H2: FAQ 

H3:Q1 What depth can PUR underwater coaxial camera cable support?

A: Standard series covers 50m, 100m, 500m shallow & medium water; reinforced Kevlar/steel armored version customized up to 3000m deep sea working depth.

H3: Q2 What is the difference between PUR sheath and TPU underwater cable?

A: Ether-based PUR has better hydrolysis resistance in long-term saltwater immersion, stronger wear resistance and low-temperature flexibility, more suitable for long-term dynamic underwater dragging camera systems; TPU fits short-term static shallow water monitoring.

H3: Q3 Can you make neutrally buoyant PUR coaxial camera cable?

A: Yes, we can add low-density filling material inside the cable to adjust overall density close to seawater, produce zero buoyancy underwater camera composite cable for small light ROV to reduce underwater drag resistance.
