A cable conduit, or cable gland, is a pipe used to route and protect cables of various kinds. In general, cable conduits are used for electric<\/a> and telecommunications cables.<\/p>\n

Since they are designed for underground installation, as part of their mechanical properties, cable glands must have a high resistance to crushing and impact.<\/p>\n

Very strong resistance to crushing is in fact the most important quality to check before purchasing a cable conduit<\/a>.<\/p>\n

Once installed, in fact, the pipe will be constantly subjected to the static load as well as any load due to above-ground stresses such as vehicle load.<\/p>\n

Impact resistance is the second characteristic that every cable conduit must have, it is essential especially when laying the product.<\/p>\n

When the pipe is laid underground, in fact, the outer surface is accidentally stressed by stones that can fall with more or less force on the pipe.<\/p>\n

Therefore, it is advisable that the soil layer adjacent to the cable gland is free of stones and consists of small-grained crushed stone or sand. Should larger rocks hit the cable conduit, there is no guarantee that it will withstand the impact without breaking.<\/p>\n

When we talk about a corrugated cable gland<\/strong>, we are referring to a double-wall cable conduit<\/strong>, which means that it consists of two co-extruded tubular elements. The one on the outside has a corrugated surface while the one on the inside is smooth. The two layers cannot separate due to the co-extrusion used in the manufacturing process.<\/p>\n

Therefore, there is no difference between cable conduit and corrugated pipe<\/strong>, we are talking about the same product, i.e. a pipe where the cables are routed without any friction due to the smooth inner surface. On the outside, on the other hand, the corrugation ensures strong anchoring to the ground.<\/p>\n

Another common mistake is to talk about \u201celectrical corrugated pipe<\/strong>\u201d or “electrical cable conduits<\/strong>” in that no electricity flows inside the corrugations; it passes through the electric cables contained in the pipe.<\/p>\n

Generally, the double-wall cable conduit<\/strong> is manufactured from polyethylene because this material has several properties, including:<\/p>\n
