◆ Buoyancy communication signal cable has excellent characteristics such as water resistance, oil resistance, cold resistance, corrosion resistance, UV resistance, abrasion resistance, flame retardancy, bending resistance, etc. It is suitable for fast moving installation. Imported high-quality materials and new improved technology are used to make the cable smaller in outer diameter and lighter in weight, which can meet the requirements of more complex working conditions
◆ Bending resistance - optimized cable pitch+special structure design+careful material selection, suitable for high frequency bending occasions
◆ Anti electronic interference - overall tinned copper wire braiding shielding density is more than 85%, effectively resisting external high-frequency electromagnetic interference
◆ Tensile - flexible wrapping material - non-woven fabric wrapping wire body+Kevlar anti drawing filling+Kevlar wire drawing weaving, which can effectively buffer the cable from bending back and forth
◆ Special flexible special sheathing material (color can be selected by the customer) is used for the cable, and the sheath will not crack if the bending life is more than 10 million times
◆ the cable has flexibility, abrasion resistance, oil resistance, acid and alkali resistance, tensile strength, excellent waterproof performance and anti-aging performance;
◆ Conductor: multi strand superfine fine twisted oxygen free copper wire, meeting VDE0295CLASS Class 6 standard
◆ Insulation: HDPE/fluoroplastic extrusion can be used, or chemical foaming technology of foam insulation can be used, and the design can be selected according to the product characteristics
◆ Twisting: different pitch twisting
◆ Shielding: tinned copper wire braided shielding, density: above 85%
◆ Tensile parts: Kevlar rope+water blocking yarn twisted filling or Kevlar wire drawing intensive knitting
◆ Filled sheath: chemical foaming technology is adopted for PUR/TPE
◆ Outer sheath: The cable surface is coated with polyurethane (PUR)/TPE/TPV, and the extrusion technology is used.
◆ Color: blue, gray, orange, yellow, etc. (can be customized)
◆ Specific gravity of wire structure:
① Zero buoyancy cable (underwater suspension cable) 0.99 ± 0.03g/MM ³， The specific gravity of the designed cable is infinitely close to that of water,
② the floating force cable is 0.88 ± 0.06G/MM ³， The specific gravity of cable structure is less than that of water, and the cable can float on the water
◆ Water pressure classification of buoyancy cable: longitudinal water pressure resistance strength: 4.5MPa 6.0MPa 10.0MPa; Horizontal water pressure resistance strength: 10.0MPa 70MPa
◆ The maximum load-bearing drag resistance is ≤ 200KG, and the waterproof submergence depth can reach 3000m, which can be produced according to the actual use needs
◆ Temperature range: - 40 ℃~+80 ℃ (water tight network cable can be customized at - 55 ℃~+105 ℃)
◆ Characteristic impedance: signal cable 100 ± 15 Ω
◆ Bending radius of buoyancy cable:
Fixed installation: 10 × Cable outer diameter (D)
Mobile installation: when the stroke is less than 10m, the bending radius is 10 × D； When the stroke is ≥ 10m, the bending radius is 15 × D
It is applied to the information collection, work instructions, on-site live detection, camera shooting and control links between unmanned cabled submersibles, underwater robot equipment, marine exploration robots, underwater ROV remote control submersibles, underwater camera, underwater construction detection, underwater search and rescue robots, pipeline detection robots and various underwater electrical equipment and shore based equipment; The signal transmission, operation command and equipment control system link from underwater to water, underwater movement and operation of submersible equipment are controlled and monitored by the operator on the surface carrier, and power and information exchange are provided to underwater equipment by this cable; It can be used in both freshwater and seawater environments.
Normally the cables are packed by drum,carton and put on the pallet and other customized packing are available as per international standard.
