To ensure safe and reliable electrical installations, protecting cables is just as important as the quality of the cables themselves. To protect cables from mechanical damage, corrugated pipes are commonly used.
A corrugated pipe is a flexible, cylindrical tube distinguished by its grooved, wave-like outer surface. This corrugated exterior gives the pipe both high flexibility and structural strength against mechanical impact.
Thanks to these characteristics, high-quality corrugated pipes can significantly reduce installation time and costs, as they are easy to install even in areas with tight bending radiuses.
Corrugated pipes are widely used in buildings for installing cables inside walls and floors; for surface-mounted installations where cables run along walls or ceilings; and underground, when laying cables directly in soil.
PE and PP Pipes
At Sakcable’s production facility, corrugated pipes are manufactured in compliance with the international standard IEC 61386-22:2021, using two different materials: polyethylene (PE) and polypropylene (PP). Their mechanical strength is rated at 320 Newtons.
Both types of corrugated pipes are halogen-free, meaning that in the event of a fire, they do not emit toxic gases and do not pose additional health or environmental risks.
Corrugated pipes made from polypropylene also have self-extinguishing properties – they do not spread flames and emit less smoke in case of fire, improving visibility in evacuation routes.
Thanks to these features, polypropylene pipes are especially well-suited for use in schools, museums, hospitals, and other high-traffic, enclosed spaces.
Sizes and Applications
Sakcable’s corrugated pipes are available in four different sizes: 16 mm, 20 mm, 25 mm, and 32 mm.
• 16 mm and 20 mm – Ideal for indoor wiring, these sizes are commonly used in residential spaces.
• 25 mm and 32 mm – Suitable for larger-diameter cables, these sizes are mainly used in industrial and outdoor settings.
