Corrugated Double-Walled Protective Conduit 50 mm Kopos KD 50N blue (6 m / 360 m)

Kopos corrugated double-walled protective conduit KD 50N in blue is a flexible conduit designed for routing and protecting electrical cables in residential, commercial and industrial installations. The product is available in 6 m single lengths and 360 m bulk rolls, combining a corrugated outer profile with a smooth inner wall to simplify cable pulling and reduce abrasion. The conduit provides mechanical protection and electrical insulation where a durable, bendable solution is required for indoor and protected outdoor use.

Advantages

The double-walled construction delivers enhanced mechanical resistance from the corrugated exterior while the smooth interior reduces friction during installation, helping to speed up cable routing. The flexibility of the conduit allows for easy bending and positioning around obstacles without loss of protective properties. Blue color provides visual identification of routed circuits and helps maintain organized cable runs. The material resists common installation stresses and helps maintain insulation integrity over time.

Suitable for

• Routing power, control and communication cables in buildings
• Protected outdoor installations such as under eaves or in covered ducts
• Areas requiring flexible conduit routing around corners and obstructions
• Renovation projects and new electrical installations where mechanical protection is needed

Key specifications

• Nominal internal diameter: 50 mm
• Double-walled design: corrugated outer surface with smooth inner wall
• Color: blue
• Lengths available: 6 m individual pieces and 360 m bulk roll
• Flexible construction for bending and routing
• Suits indoor and protected outdoor environments

How to use

Measure and cut the conduit to the required length using appropriate cutting tools, ensuring clean, burr-free ends. Route the conduit along the planned path and secure it at regular intervals with suitable clips or straps designed for 50 mm conduit. Pull cables through the smooth inner wall to minimize friction; use lubricant if necessary for long or multiple cable pulls. Fit compatible glands, connectors or end fittings to maintain mechanical protection and prevent moisture ingress where required.

Usage recommendations

For best results, avoid exposing the conduit to direct sunlight for extended periods and protect it from prolonged contact with aggressive chemicals. Ensure correct sealing at transitions to other enclosures and use recommended accessories for bending radii and fastening to maintain performance and cable safety.
