Product Description
MV Insulating End Caps / Sealing Plugs for Switchgear & Cable Compartments
Product Description
Our MV insulating end caps (insulation plugs) are essential safety components designed to seal unused cable and bushing ports in medium-voltage switchgear, ring main units (RMUs), and transformer enclosures. These high-performance caps provide reliable electrical insulation, preventing flashovers, contamination, and moisture ingress, while protecting against accidental contact with live parts.
Made from durable, high-grade insulating materials, our end caps offer excellent dielectric strength, UV resistance, and long-term stability in both indoor and outdoor environments.
Key Features
- High dielectric strength, meeting MV equipment safety standards
- Seals unused ports to prevent dust, moisture, and contamination
- Provides protection against accidental contact with live components
- Resistant to aging, UV radiation, and environmental stress
- Available in standard sizes for common switchgear port dimensions
- Custom designs available for non-standard applications
- Easy to install and remove during maintenance
Applications
- Sealing unused cable ports in MV switchgear and RMUs
- Insulating and protecting bushing ends and terminals
- Cable compartment sealing in ring main units
- End protection for instrument transformers and sensors
- Indoor and outdoor medium-voltage distribution equipment
