Overview
Watertight 2-core twisted pair cable is a cable product that combines multiple high-performance materials. It usually consists of an internal conductor, an intermediate insulation layer, and an external protective layer. Among them, Kevlar fiber and thermoplastic polyurethane are two key materials that each contribute unique properties, making this cable perform well in various application scenarios.
Product Details
2-core double shielded watertight cableThrough polyurethane（PUR or polyvinyl chloride (PVC) sheath achieves IP68 protection level, and some models integrate waterproof adhesive filling, which can work for a long time without leakage at a depth of 100 meters underwater.
Application scenarios:Underwater equipment connectionSuitable for dynamic working environments such as submersible motors, underwater robots, sonar towing arrays, etc，Industrial control signal transmissionUsed in corrosive environments such as ship communication, ocean exploration platforms, and salt lake water extraction equipment，High interference environmentIn situations where dual shielding is required, such as mine automation systems and metallurgical workshops.
Typical structural composition
The 2-core double shielded waterproof cable is designed specifically for underwater or high humidity environments, and its multi-layer composite structure ensures waterproofing, anti-interference, and mechanical stability:
Conductor layer：Waterproof 2-core twisted pair cableUsing multi strand precision twisted oxygen free copper wire or tin plated copper wire, providing high conductivity and flexibility, supporting frequent bending and dragging movements.
insulating layerPolyvinyl chloride (PVC) or polyurethane (PUR) materials wrap conductors to enhance electrical insulation and chemical corrosion resistance, adapting to complex underwater environments.
Double shielding layer：
Inner layer shieldingWrap with aluminum foil or copper tape to achieve near end electromagnetic interference (EMI) resistance and prevent signal crosstalk.
Outer shieldingTin plated copper wire woven mesh (density>80%) provides remote anti-interference ability to ensure signal transmission stability.
AquicludeSealing with waterproof adhesive or foam waterproof tape can delay moisture penetration even if the sheath is damaged, ensuring equipment reliability.
sheath layerPolyurethane (PUR) or polyvinyl chloride (PVC) materials have high wear resistance, oil resistance, and impact resistance to resist physical damage during towing.
Selection and customization suggestions
Parameter focusWhen selecting, it is necessary to consider the rated voltage (such as 300/500V), temperature range (-30 ℃ to+70 ℃), and minimum bending radius (usually 4 times the outer diameter of the cable).
Customization optionsArmor layers (such as steel strips or wires) can be added as needed to enhance load-bearing capacity, or the color of the sheath can be adjusted (such as black or orange).
Certification and Standards: ReferenceWaterproof 2-core twisted pair cableCable specifications (such as static water immersion testing) ensure that products pass strict waterproof assessments and meet industry safety requirements.
