Email: sales8@hihuanghecable.com
Solid Conductor Core: Features a single, solid rod of 99.9% Pure Annealed Copper for maximum electrical stability.
High-Grade XLPE Insulation: Cross-linked Polyethylene provides superior heat resistance, allowing the core to run safely at 90°C .
Standard PVC Option: Also available with high-quality PVC insulation for standard building applications (rated at 70°C ).
Solid vs. Stranded: The solid core design is stiffer and more compact, making it ideal for permanent terminal connections.
Triple Voltage Rating: Engineered to meet 300/500V , 450/750V , and heavy-duty 0.6/1kV requirements.
Rugged Outer Sheath: Encased in a flame-retardant PVC jacket that protects against UV rays and mechanical impact.
Environmental Shield: Highly resistant to moisture, acids, and alkalis, making it suitable for damp walls or conduits.
Thermal Security: Capable of withstanding short-circuit temperatures up to 250°C without melting (XLPE version).
Space Saving: The solid core offers a smaller outer diameter compared to stranded cables of the same capacity 10.Global Certification: Fully compliant with IEC 60502-1 and UL safety standards for international projects.

PVC Insulated Nylon Sheath THHN Wire Cable
STRUCTURE
This 10-line technical breakdown explains the high-performance build of these cables:
High-Purity Conductor: Uses 99.9% soft-annealed copper for maximum conductivity and energy efficiency.
Flexible Stranded Design: Features 19 or more copper strands to allow for easier bending and installation in conduits.
Advanced PVC Insulation: A robust primary layer of flame-retardant Polyvinyl Chloride (PVC) that prevents electrical leakage.
Tough Nylon Outer Jacket: A thin, clear polyamide "skin" that provides superior abrasion resistance and protection against mechanical damage.
Easy-Pull Surface: The smooth, "slippery" nylon jacket reduces friction, allowing the wire to be pulled through pipes with 50% less effort.
Dual/Triple Rating: Fully certified as THHN, THWN, and THWN-2 , allowing one wire to serve multiple environmental needs.
90°C Thermal Limit: Engineered to handle continuous high heat up to 90°C (194°F) in both wet and dry locations (for THWN-2).
Chemical Resistance: The nylon shield is highly resistant to gasoline, oil, acids, and industrial solvents.
Standard Voltage (600V): Fully rated for standard building services, with heavy-duty versions available for 0.6/1kV systems
Global Safety Compliance: Manufactured to strictly follow UL 83 and IEC safety standards for guaranteed industrial reliability
