Special cable for underwater camera sonar

For applications such as ocean sonar detection, choosingunderwaterCamera sonar dedicated cableAt this time, the reliability of its sealing technology should be given special attention. ‌Traditional water blocking paste filled transverse sealIt performs well in static or mild environments, but there are risks in dynamic and high-pressure complex marine environments. ‌Adopting longitudinal sealing assistance or new composite sealing technologyThe cable can effectively resist moisture intrusion through multiple barriers, significantly improving its waterproof reliability and overall lifespan during long-term service, making it a more suitable choice for harsh underwater detection environments.

Special cable for underwater camera sonarIt is the core component of deep-sea exploration systems, responsible for the key tasks of sonar signal transmission, equipment power supply, and data return.

Dynamic sealing and pressure resistant structure

‌Horizontal and vertical sealing technologyUsing flexible sealant and multi-layer sheath, it can still prevent longitudinal penetration of seawater under a pressure of 10 megapascals, ensuring the integrity of the cable in kilometers of water depth.

‌Innovation in Sheath MaterialsAdding repellents to resist biological attachment, combined with antioxidants to delay corrosion, significantly extends the service life of cables in salt spray environments.

Signal transmission optimization

‌Double layer shielding designAluminum foil and tin plated copper mesh weaving layer suppress electromagnetic interference, ensuring "zero loss" transmission of sonar data from deep sea to surface.

‌Conductor twisting processMulti strand ultra-fine oxygen free copper wire enhances flexibility, supports repeated bending without breaking, and adapts to the maneuvering needs of AUVs (autonomous underwater vehicles).

Buoyancy and fatigue resistance performance

‌Positive buoyancy structureClosed cell foam material makes the cable float as a whole, avoiding the risk of "overhanging" in deep-sea operations and reducing water flow resistance.

‌Lateral pressure resistant designOptimize the sheath formula to enhance its resistance to mechanical impact and maintain stability under ocean currents.

The decisive role of sealing performance‌
