SemiCon
Semiconductive Strand-Fill Sealant
A semiconductive strand-fill compound designed to fill the interstitial voids within stranded medium- and high-voltage cable conductors, preventing longitudinal water migration while maintaining electrical continuity across the conductor cross-section. This compound is a drop-in alternative to conventional polyisobutylene (PIB)-based strand fillers, compatible with standard twin-screw compounding and side-feed or in-line application equipment — no specialized tooling required.
Applications
- Medium-voltage (5–35 kV) shielded power cable
- High-voltage and extra-high-voltage transmission cable
- Compact and standard concentric stranded copper and aluminum conductors
