BLACKCOR – HDPE double wall corrugated pipe for cable protection

BRIEF DESCRIPTION

Double wall corrugated pipes made of high-density polyethylene (HDPE), smooth on the inside wall and corrugated outside, for underground cable protection networks.
Diameters (DN/OD) go from 40 up to 200 mm, all available in coils, and in lengths from DN75 mm size.

Standard colour is totally black, to increase the UV resistance. It can be equipped with one coextruded coloured stripe on the outside wall, according to customers’ need.

Electrical rigidity*: Excellent (polyethylene 20-30 kV/mm)

*Electrical rigidity, also known as dielectric strength or breakdown voltage, represents the ability of a material to withstand a certain electric voltage before a discharge or breakdown occurs. High electrical rigidity is desirable in materials intended for electrical insulation, such as those used in cables, transformers, capacitors, and other electrical and electronic components.

Electrical rigidity is primarily classified based on the breakdown voltage, which depends on the material and its thickness.
