Corrugated Double-Wall Protective Conduit Kopos KD 110N, Ø110 mm, blue

Kopos KD 110N is a corrugated double-wall protective conduit with a nominal diameter of 110 mm in blue, designed to protect electrical and telecommunication cables. The product combines a rigid outer wall for mechanical resistance with a flexible inner corrugated structure that facilitates bending and routing in confined spaces. It is suitable for both underground installations and indoor applications where a robust, bendable cable protection system is required.

Advantages

The double-wall design provides enhanced mechanical protection against impacts and soil pressure while maintaining flexibility for easy installation around obstacles. The smooth inner surface reduces friction during cable pulling and helps protect cable insulation. The blue color offers clear visual identification for data and telecommunication lines or other designated circuits. The conduit is resistant to common environmental conditions encountered in buried and indoor installations.

Suitable for

• Protection of electrical power and telecommunication cables in underground ducts
• Indoor cable routing in technical rooms, cable trays, and false floors
• Applications requiring flexible routing around bends and obstacles
• Projects that need color-coded conduit for system identification

Key specifications

• Nominal inner diameter: 110 mm
• Double-wall construction: rigid outer wall with corrugated inner wall
• Color: blue
• Suitable for underground and indoor installations
• Designed for protection of electrical and telecommunication cables
• Flexible for bending and routing in confined spaces

How to use

Plan the conduit route and ensure the trench or channel meets local installation requirements for depth and separation from other services. Cut the conduit to the required length using appropriate tools, taking care to obtain clean ends. Join sections with compatible couplers or fittings designed for double-wall conduits, and seal joints where required for watertight or gas-tight installations. Pull cables through using standard cable installation techniques; the smooth inner surface reduces friction but use a pulling lubricant if long runs or multiple bends increase resistance. Backfill buried runs with suitable material and compact according to local codes, avoiding sharp stones or debris that could damage the conduit.

Usage recommendations

Verify compatibility of fittings and accessories with double-wall corrugated construction and follow local electrical and building regulations for burial depth, separation distances, and marking. Use color-coding consistently across the installation to identify system type and facilitate future maintenance.
