Underwater Robot Cable
1. Application: This product is mainly used in underwater robots, underwater salvage equipment, underwater construction equipment, underwater robotic arms, underwater hydraulic cutters and other mechanical equipment operating in harsh underwater environments. It can be towed in water with the equipment. Pull and stretch to use.
2. Product description
◆ Conductor uses multi-strand finely stranded tinned copper wire
◆ Insulation: TPE or polyolefin material
◆ Number of cable cores: 2-4 cores
◆ Multi-core cabled, filled with Kevlar
◆ Inner sheath: low viscosity elastomer
◆ Outer sheath: high-strength foamed polyurethane material
◆ The rated voltage Uo/U is 300/300V
◆ Withstand voltage test voltage 1500V 50-60Hz 1min
◆ The maximum allowable working temperature of this cable is -50∽80℃
◆ Water pressure resistance: longitudinal water pressure resistance: 4.5MPa
◆ Transverse hydraulic pressure resistance: 10.0MPa
3. Characteristics of floating cable:
Corrosion resistance: The corrosion resistance of cable conductors used in water must be considered, because conductors are particularly susceptible to oxidation in the presence of water, especially in seawater.
Tensile resistance: As the link between the underwater vehicle and the control center, the floating cable needs to have tensile properties.
Anti-hydrolysis: This kind of cable works best in water, and water has a decomposition effect on polymer materials, so this kind of cable must have anti-hydrolysis characteristics
Water resistance: This type of cable also has water resistance, including longitudinal waterproofing and axial waterproofing.
Buoyancy: Zero buoyancy/positive buoyancy.
