Protective Conduit Pipe TTPLAST 10880 ROS-Z (RHDPEp) 125/7.1 rigid 6 m black

Rigid protective conduit pipe TTPLAST 10880 ROS-Z is a black RHDPEp conduit with a nominal internal diameter of 125 mm and a wall thickness of 7.1 mm, supplied in 6 m lengths. It is designed for mechanical protection of electrical and communication cables in both underground and surface installations. The non-metallic construction provides resistance to corrosion and many chemicals, while the rigid profile maintains route geometry and supports cable loads in ducting and infrastructure applications.

Advantages

The TTPLAST ROS-Z conduit combines a durable rigid high-density polymer construction with consistent wall thickness for predictable mechanical performance. Its 125 mm diameter and 7.1 mm wall deliver sufficient bending stiffness for long runs and load-bearing in trenches or ducts. Being non-metallic, the conduit resists corrosion and eliminates electrical conductivity concerns, making it suitable for varied environmental conditions. Standard 6 m lengths simplify handling and joining on site.

Suitable for

• Protection of electrical power cables in underground ducting
• Routing fiber-optic and communication cables
• Infrastructure and utility projects requiring non-metallic conduits
• Trench installations and cable ducts where corrosion resistance is required

Key specifications

• Material: rigid recycled/high-density polyethylene (RHDPEp)
• Nominal internal diameter: 125 mm
• Wall thickness: 7.1 mm
• Length: 6 m per section
• Color: black
• Mechanical characteristic: rigid, high bending stiffness
• Environmental resistance: corrosion and many chemical resistant

How to use

Install the conduit by preparing a clean trench or duct route that accommodates the 125 mm diameter and provides appropriate bedding support. Cut the 6 m sections to length where required using an appropriate saw designed for polyethylene. Ensure end faces are smooth before making joints; use compatible couplers or sealing methods recommended for rigid polyethylene conduits. When pulling cables, protect cable terminations and use proper lubrication and pulling equipment to avoid damage to the cable or conduit walls.

Usage recommendations

For long runs, ensure adequate expansion joints or allowances for temperature-driven length changes. Provide sufficient bedding and backfill materials to distribute loads and avoid point stresses. Follow local regulations and standards for minimum cover depth and separation from other utilities. Use dedicated couplers and seals suitable for rigid polyethylene to maintain mechanical integrity and environmental protection.
