LS-15 15kV Cold Shrinkable Termination Kit
NLS-15 / WLS-15
15kV Silicone Rubber Cold Shrink Termination Kit for Cross-linked Cable
Application Range
This series is suitable for 6/10kV and 8.7/15kV cross-linked (XLPE) power cables.
It is widely used in outdoor/indoor terminations for power distribution networks, substations, industrial facilities, and utility cable installations.
Product Features
High-performance silicone rubber
Made from liquid silicone rubber with excellent tear resistance, anti-tracking properties, corrosion resistance, and stable electrical insulation performance.
Integrated stress control & insulation
The integrated structure eliminates interlayer air gaps, optimizes electric field distribution, and reduces installation procedures.
High elasticity for stable operation
Silicone rubber’s strong elasticity compensates for cable breathing during thermal cycles, preventing installation defects.
Clear phase identification
Red, yellow, and green sealing tubes provide intuitive and accurate phase separation.
Safe and flame-free installation
No open flame or heat source required. Simple, safe, and reliable installation suitable for various on-site conditions.
