Pre-Insulated Cable Sleeves are designed for reliable connection of low-voltage aerial bundled cables (LV-ABC), including phase conductors and neutral messenger lines.
Manufactured from high-purity aluminum and equipped with a weather-resistant insulation sheath, these sleeves provide excellent electrical continuity, mechanical strength, and long-term protection against moisture, corrosion, and environmental aging. Pre-filled contact grease and elastomeric sealing rings ensure superior waterproofing, making the sleeves suitable for outdoor distribution networks.
