Neutrally buoyant underwater cable ROV umbilical cable kevlar reinforced cable

Neutral buoyancy cable

With the development of marine resources, the more the use of the underwater robot, the complex movement of the underwater robot requires the use of a flexible or three-dimensional flexible cable, and requires that these cables have similar service life as those used in the linear drag chain system. the core, strand, shield and sheath material must be capable of withstanding the compressive forces produced upon bending and the change in the radial pressure produced by the torsional motion. The underwater robot cable uses the high wear-resisting property and the PU sheath material, and can effectively protect the twist-optimized twisted-in element from being damaged.

Neutral buoyancy cables are mostly used for underwater vehicle or underwater equipment control signal lines. Conventional (sea) hydroelectricity cables will sink in the (sea) water because the density is greater than the underwater density, and the floating cable density for buoys will have a certain buoyancy if the density of the floating cable is small, This seriously affects the operating accuracy of underwater equipment. The zero-buoyancy cable, however, can be kept at the same density in water, neither sinking nor rising. Reduce the impact on equipment operation.

Product characteristics 

The water-tight network cable can be used in deep water, especially in deep water, with longitudinal water-tight characteristics, and the sea water does not penetrate into the deep-water electric cable for ships inside the cable

1.Stable signal transmission, strong conductor toughness: multiple fine twisted oxygen free copper wire as a conductor to ensure the flexibility of the line body
2. Excellent anti-jamming ability: 1. Aluminum foil shield 2. Tin plated copper mesh braided to effectively resist external low frequency and high frequency electromagnetic interference
3. Excellent bending resistance: optimized cable pitch special structure design meticulous material selection, suitable for high-frequency bending situation continuous core
4. Excellent tensile strength: kafla fiber filling can increase tensile strength according to customer requirements. Flexible wrap material-non-woven wrapped wire body with anti-tension filler, bending motion of cable back and forth is an effective buffering effect
5. Good temperature tolerance: 1. The PVC special underwater network wire is -15 ℃ ~ 70 ℃, and the underwater special network wire is -40 ℃ ~ 70 ℃.
6. Good wear resistance: special production technology and high quality outer sheath materials, wear-resistant, oil-resistant, anti-aging-special flexible special sheath materials (color can be selected by the customer) bending life of more than 5 million sheathing does not break.

Cable structure:

1.Conductor: High-flexibility (90.9%) oxygen-free copper wire (or changed to tinned copper conductor)
2.Insulation: foamed thermoplastic elastomer/ TPE/ TPV material as the insulation material of the cable;

4.Core color: black digital distinction, or color line core color discrimination
5.Shielding: aluminum foil wrapped in Mala, braided shield with high-flexible tin-plated copper mesh
6.Shielding structure: split screen (single layer or double layer) main screen (single layer or double layer); total screen (single layer or double layer)
7.Winding: flexible nonwoven / polyester tape wrapped
8.Tensile fill: Kafla center or gap filling, as well as Kafla tensile fabric layer (customized as required); 

9.Outer sheath: high flexible foamed polyurethane material, wear resistance, tensile resistance, waterproof, oil resistance, cold resistance, corrosion resistance
