EVOCAB SUPERHARD N 1250
Reinforced corrugated double-wall pipes
Normal Impact resistance, Compression strength: 1250, DN/OD 110 .. 400 mm
EVOCAB SUPERHARD N 1250 reinforced double-wall cable protection pipes are designed for underground high-voltage cable lines.
By design they have structured walls: corrugated outer wall ensures high compression strength properties thanks to their special profile. The smooth inner surface of the pipe ensures easy pulling of cables. Due to their special structural properties, these cable protection pipes are lighter, but more rigid, as well as more impact-resistant than the conventional smooth-wall pipes.
SUPERHARD pipes are supplied in straight 6 m bars (+ coupler).
- Available sizes: DN/OD 110 .. 400 [mm]
- Compression strength class: 1250
- Pipe length: 6 [m] + coupler
-
Advantages
- High compression strength allows installation of the conduits at shallower depths, thereby shortening the installation time and optimising the costs
- Quicker, more convenient, and more cost-effective construction of high-voltage cable networks
- Easy, safe, and fully hermetic coupling of the conduits
- High impact strength is maintained even at the lowest temperatures
- Chemically inert, with high corrosion resistance.
- Service life: minimum 50 years
-
Recommended application
Protection of electrical systems near railway lines
Onshore wind parks
SUPERHARD cable protection pipes are made of a rigid material and designed to withstand soil and vehicle loads. They provide long-term protection of high-voltage cables in high-load conditions, e.g. installations under traffic lanes.
These pipes can be used for underground protection and insulation of cables and are especially suitable for systems requiring a high compression strength, i.e. under roads, squares, etc.
