Cable Sealing Performance Features
-
Constant Radial Pressure: Active compression ensures tight seals during thermal expansion and contraction cycles.
-
Hydrophobic Surface: Premium silicone shrink wrap rejects water accumulation and reduces surface discharge risks.
-
High Dielectric Strength: Superior breakdown voltage properties safeguard 8.7/15kV cable terminations and splices.
