Product Description
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
