Core Features

1. Excellent resistance to electrical erosion and tracking. In high-voltage electric fields and humid, contaminated environments, the sheath surface is less prone to leakage tracking and electrical erosion ablation. It can withstand the coupling potential of high-voltage lines and prevent arc burning and cracking on the sheath surface, suitable for pole-mounted installation alongside 110kV and 220kV high-voltage transmission lines. Ordinary HDPE sheaths cannot meet the working conditions of high-voltage electric fields.

2. Strong UV aging resistance and weatherability. Formulated with special carbon black and anti-aging systems, its mechanical and electrical properties degrade slowly under long-term outdoor exposure, wind, rain, snow and ice, meeting the service life requirement of over 20 years for ADSS optical cables.

3. Good low-temperature toughness. It is not susceptible to brittle cracking at low temperatures, maintaining outstanding impact resistance and environmental stress cracking resistance even at -40℃, suitable for regions with alternating high and low temperatures and ice-snow loads.

4. Extremely low water absorption and great chemical stability. Barely absorbs water; resistant to weak acids, salt spray and atmospheric pollutants, maintaining long-term stability in polluted coastal and industrial areas.

5. Superior electrical insulation performance. High volume resistivity and excellent dielectric strength with stable insulation. As a non-metallic material, it is immune to electromagnetic interference.

6. Good extrusion processability. Being thermoplastic, it enables smooth extrusion molding and yields dense sheath surfaces, compatible with high-speed sheath extrusion production lines for optical cables.
