Product Description

WANGYUAN Top ceramic pre-twisted wire are specifically engineered for overhead transmission and distribution power systems. The strand bodies are manufactured from high-strength hot-dip galvanized steel wire or electrical aluminum alloy wire with UV-resistant polymer through precision twisting process, with uniform pitch, smooth surface and excellent tensile strength, high temperature resistance and anti-fatigue performance. Featuring an innovative helical self-gripping structure, these products evenly disperse the clamping force along the ceramic insulator, effectively avoiding stress concentration and strand damage caused by traditional point-clamping fittings. All products are manufactured in strict accordance with IEC 61284 and relevant international power standards, maintaining stable performance in harsh outdoor environments such as high temperature, high humidity and coastal salt spray.

Advantages

Uniform & Reliable Grip Performance

Helical wrapping structure distributes clamping force evenly over long contact length, no damage to ceramic insulator, stable tensile load capacity, no slipping under long-term operation.

Excellent Anti-fatigue & Protection Performance

High-strength twisted structure with wear-resistant polymer surface effectively absorbs line vibration, reduces breeze vibration damage, protects insulator surface from wear, significantly extends cable service life.

Superior Weather & Corrosion Resistance

UV-resistant polymer-reinforced hot-dip galvanized steel or aluminum alloy material, stronger rust and corrosion resistance with high temperature endurance, suitable for long-term outdoor operation in coastal, industrial and plateau environments.

Efficient & Convenient Installation

Lightweight preformed structure, no special tools required, manual wrapping installation, fast on-site assembly, effectively reduces construction period and labor cost.
