Cable Protection Pipe With Pulling Wire SRN 50mx50/40mm Yellow Malmbergs 0666716

Description

A yellow, double-walled and halogen-free cable protection pipe in high-quality HDPE. The pipe is constructed with a corrugated outside for optimal strength and a smooth, transparent/white inside that facilitates cable routing. It is perfect for safe and durable cable installations in the ground.

Each roll is delivered complete with a mounted joint sleeve and a corrosion-resistant metal pulling wire for smooth cable pulling. The pipe meets the strict requirements of EBR KJ 41:21.1 and SS 424 14 37. To create completely tight systems (up to 0.5 bar), the pipe is simply supplemented with the associated sealing ring.

Construction advantages & Material properties

• Double-walled structure: The corrugated HDPE outer side provides high mechanical strength and impact resistance against ground pressure and stones. The smooth inner side minimizes friction when the cable is pulled through.
• Halogen-free plastic: The HDPE material does not emit any corrosive or toxic gases when in contact with high heat, which improves both the environmental profile and safety.
• Integrated pull wire: Each ring is delivered with a pre-assembled, corrosion-protected metal wire that eliminates the need for a separate search spring when feeding the cable.
• Wide temperature tolerance: Withstands installation and operation in extreme cold and high heat (-25 °C to +90 °C), making it well suited for the Nordic climate.

Standards & Tightness

The pipe meets the requirements of the Swedish network standard according to EBR KJ 41:21.1 and SS 424 14 37. Supplied with a joint sleeve as standard. When laying in water-bearing or damp ground conditions, the connections are supplemented with a sealing ring (Diameter 50 mm) to achieve a certified waterproof system up to 0.5 bar.
