Corrugated PVC conduit TTPLAST RKSSP 23/18-50 FI18/23 750N with pilot wire 50 m

Corrugated PVC conduit TTPLAST RKSSP 23/18-50 FI18/23 750N with pilot wire 50 m is a flexible protective pipe designed for electrical installations. Constructed from corrugated PVC, the conduit provides mechanical protection and moisture resistance for power, control and communication cables. Supplied as a 50 m length with an integrated pilot (signal) wire, it supports routing of cables in both underground and surface applications for residential and commercial projects.

Advantages

The TTPLAST RKSSP corrugated conduit combines flexibility with a defined compressive strength rating of 750 N, allowing easier installation through bends and around obstacles while offering reliable protection against crushing and external mechanical loads. The integrated pilot wire simplifies the process of locating or pulling conductors later and reduces the need for an additional locating tape or separate tracer. The PVC material ensures resistance to moisture and many common construction site conditions, and the corrugated profile improves bending performance compared with rigid conduits.

Suitable for

• Routing power, control or communication cables underground in residential and commercial sites
• Surface installations where flexible protection around bends and through walls is required
• Applications that benefit from a pilot/tracer wire for cable detection or pulling
• Areas where moderate compressive load protection (up to 750 N) is needed

When it may not be suitable

This conduit is not intended for direct exposure to high temperatures, open flame or chemical environments that attack PVC. It is designed for moderate mechanical loads up to the specified 750 N rating; situations that require structural protection against heavy vehicle traffic or very high compressive forces will need more robust, engineered solutions such as concrete-encased ducts or metallic conduits rated for those conditions. For installations requiring fire-resistant or halogen-free materials, alternative products should be considered.

Key specifications

• Material: Corrugated PVC (polyvinyl chloride)
• Nominal conduit outer/inner profile: FI18/23 (corrugated dimensions)
• Compressive strength: 750 N
• Included accessory: integrated pilot (signal) wire
• Length: 50 m
• Flexibility: corrugated profile for improved bending radius
• Environmental resistance: moisture-resistant suitable for underground and surface routing

How to use

Measure and cut the conduit to the required length using appropriate cutting tools for PVC, ensuring clean, burr-free ends. Route the conduit through trenches, ducts, walls or cable trays following local installation standards and avoid sharp kinks to preserve flexibility. Use suitable fittings, couplers and seals designed for corrugated PVC conduit to maintain mechanical protection and moisture resistance at joints. Use the integrated pilot wire to pull cables or as a tracing conductor during route identification, taking care to separate high-voltage conductors from the pilot when required by local electrical codes.

What to consider before purchase

• Verify the conduit internal diameter and corrugated profile match cable bundle diameters and bending requirements
• Confirm the 750 N compressive rating is adequate for expected mechanical loads in the installation location
• Check compatibility of fittings and couplers with corrugated PVC FI18/23 profile
• Consider environmental conditions (temperature range, chemical exposure, UV) to ensure PVC is suitable

Usage recommendations

For durable results, install the conduit following local electrical regulations, avoid excessive compression at joints, and use approved connectors and sealing methods. When pulling multiple cables, use the pilot wire for initial guidance and protect cable ends to prevent abrasion. For buried routes under traffic or heavy loads, consider additional mechanical protection or specifying a higher-rated duct.
