Ceramic Insulation Sealing Plugs for MV Cable Joints & Terminations | Moisture-Proof End Closures

Our ceramic insulation sealing plugs are heavy-duty end closures designed for medium-voltage cable joints, separable connectors and cable termination enclosures. Combining high-grade ceramic insulation with precision-fit sealing geometry, these plugs provide reliable electrical insulation while preventing moisture and contamination ingress into cable compartments.

Compared to polymer-only plugs, our ceramic sealing solutions offer superior heat resistance, longer service life and better performance under fault current conditions — ideal for underground cable networks and outdoor cable boxes.

Key Features
  • Dual function: electrical insulation + environmental sealing
  • High-temperature ceramic body for fault current resistance
  • Precision dimensional tolerance for leak-tight fit
  • Resistant to oil, UV, ozone and chemical corrosion
  • Suitable for indoor and outdoor cable installations
  • Available in standard cable bore sizes (630A, 1250A, 2500A class)
  • Compatible with cold-shrink and heat-shrink cable accessories
Applications
  • MV cable joint and termination enclosures
  • Separable connector systems (elbow connectors)
  • Ring main unit cable compartment sealing
  • Pad-mounted transformer cable entry points
  • Underground distribution network cable boxes
