Zhongchao's Silane XLPE (Crosslinked Polyethylene) insulation compound is specifically designed for aerial insulated cables with voltage ratings up to 10kV. This one-step silane crosslinking process ensures superior performance, making it an ideal choice for demanding electrical applications, such as aerial cables. Manufactured with high-quality polyethylene resin and advanced additives, this material provides excellent physical and chemical properties, ensuring the reliability and long-term durability of your cable systems.
Our Silane XLPE insulation compound guarantees consistent extrusion performance, ensuring a uniform coating on cables. The formulation allows for easy processing with a conventional extruder, providing high efficiency in cable manufacturing.
With a tensile strength of up to 22 MPa and an elongation at break of over 600%, this compound demonstrates remarkable resistance to mechanical stress. It ensures the mechanical integrity of cables, even in harsh environmental conditions.
The compound maintains its integrity at high temperatures, with excellent hot set behavior, even under stress. This is crucial for aerial cables that experience varying thermal conditions in outdoor applications.
The Silane XLPE compound has shown minimal degradation in both tensile strength (+5%) and elongation (-6%) after ageing, ensuring long-term performance under real-world conditions.
The compound performs well even at extremely low temperatures (-76ºC), maintaining its flexibility and ensuring reliability in cold climates.
With high dielectric strength (up to 38 MV/m) and excellent volume resistivity (up to 1x10^15 Ω·cm), this insulation compound provides exceptional electrical performance, preventing breakdowns and maintaining operational efficiency in aerial cables.
The Silane XLPE insulation compound is vacuum-packed in aluminum foil bags with a net weight of 25±0.05 kg per bag, ensuring safe and efficient transportation and handling.

Typical values in the table are measured under the condition that the material is fully crosslinked, and if suficient crosslinking is not achieved, the performance of the material may be different.
it is recommended to use a conventional extruder (three-layer co-extrusion, length-diameter ratio of 20:1 to 30:1)for operation, and other equipment needs to be adjusted according to the situation.
