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
