Waterproof yarn insulation material for cables

The long-term reliability of cables is directly related to system safety in fields such as power transmission, communication networks, and rail transit. Cable Using waterproof yarn insulation material with unique Expansion blocking water,Mechanism and Insulation protection  Performance has become the core material for resisting moisture erosion and ensuring cable life.   1. Innovate the water blocking mechanism to completely isolate water hazards. Traditional cables are prone to short circuits, aging, and even breakdown due to moisture infiltration. Water blocking yarn  reconstructs the protection system through the following methods:

-Intelligent expansion and water resistance : Embedded yarn ,Highly absorbent resin  (SAP), rapidly expands by 300% -800% upon contact with water, tightly fills the gaps in the cable core, and forms a physical Vertical barrier Completely block the longitudinal/radial migration of water molecules.  

Double protection design,Combined with waterproof powder/waterproof tape, construct a “point line surface” three-dimensional protective net, suitable for submarine cables, underground direct burial, etcHigh humidity environment .

2. Strengthen insulation performance to ensure electrical safety

In addition to its core function of water blocking, the material itself has excellent electrical properties:

 High insulation strength Volume resistivity>10 ¹⁴Ω· cm, dielectric strength ≥ 25 kV/mm, effectively isolating current leakage between conductors.    Temperature adaptability Temperature resistance range -40 ℃ to 90 ℃, combined with cable insulation layer (such as XLPE) to resist thermal cycling stress and avoid caused by temperature difference condensation.  

3. Lightweight and compatibility, optimizing cable design

Space savingThe diameter of the yarn like structure is only 0.3-1.0mm, replacing traditional heavy metal sheaths, reducing cable weight by more than 30%, and improving laying efficiency.    Full material compatibility : Compared to polyethylene (PE), polyvinyl chloride (PVC), etc. Insulation material Seamless integration, without interfering with the original electrical performance and mechanical strength.

4. Strict certification, adapted to key scenarios and certified according to standards such as IEC 60502 and GB/T 12706, meeting:

High voltage power cables (35kV and above) require water resistance

 Submarine optical cable Anti penetration corrosion protection

Rail Transit Cable Moisture proof and anti condensation design

Data center,Waterproof insulation  Redundant backup

Summary: Waterproof yarn insulation material for cables is Expansion resistance As the core concept, through Highly absorbent resin Intelligent response and! Vertical barrier Technology has redefined the moisture-proof standards for cables. It is not only for  Insulation material, Injecting innovative power into the system, providing high reliability and lightweight protection solutions for key fields such as energy and communication, becoming an indispensable safety cornerstone in modern cable design.
