LS-35 35kV Cold Shrinkable Terminal Kit
Product Application:
The NLS-35 / WLS-35 Series is designed for 35 kV cross-linked (XLPE) power cable termination, providing reliable insulation, sealing and mechanical protection. It is suitable for indoor and outdoor terminations in distribution networks, substations and industrial power systems, especially where convenient installation and long-term performance are required.
Product Features:
• Manufactured from liquid silicone rubber with excellent tear resistance, tracking resistance, corrosion resistance and electrical properties
• Integrated stress control and insulation design effectively avoids interlayer air gaps and reduces installation steps
• High elasticity of silicone rubber helps eliminate defects caused by the breathing effect of cables
• Equipped with constant force springs, eliminating the need for welding of the earthing and shielding connection
• Red, yellow and green sealing tubes provide clear phase identification and easy phase separation
• Cold-shrink technology, no need for open flame heating, ensuring easy installation, safety and reliability
