The J801 Overhead Cable Fixing Device (Top Fixation) feature a fully insulated structure engineered with UV-resistant, high-strength composite insulating materials, delivering acid rain resistance, salt mist corrosion resistance, and superior aging performance. Its non-abrasive clamping interface secures conductors without compromising the outer jacket or insulation layer, effectively eliminating safety hazards caused by corrosion-induced strand breakage in manual binding methods and operational insulation wear-induced leakage currents. With versatile compatibility for conductors across distribution networks, this solution enables tool-free installation while maintaining 100% dielectric integrity at up to 35kV systems.
