Generally, however, there is a tendency to identify the type of cables housed inside the pipes by the external colour of the corrugated pipe.<\/p>\n<p style=\"text-align: left;\">Let&#8217;s look at the commonly distinguishing external colours for Italy, for example:<\/p>\n<ul class=\"list-marked\">\n<li>electrical cables: black, grey or red;<\/li>\n<li>gas pipes: yellow;<\/li>\n<li>telephone cables: blue.<\/li>\n<\/ul>\n<p style=\"text-align: left;\">Whereas the internal colour of all cable conduits is normally black.<\/p>\n<p style=\"text-align: left;\">There are many types of cables and installations as well as colours that can be applied to each <strong>cable conduit <\/strong>to distinguish them. For this reason, cable conduit manufacturers tend to use standard colours that can be modified at the customer&#8217;s request using a colour masterbatch.<\/p>\n<p style=\"text-align: left;\">For example, Polieco produces its cable conduits in black as standard, but it is also possible to make the <strong>corrugated pipe red<\/strong>, blue, green or yellow.<\/p>\n<p style=\"text-align: left;\">ENEL and TELECOM cable conduits are a different matter. They are identified by precise technical but also colour specifications for use in these installations:<\/p>\n<ul class=\"list-marked\">\n<li style=\"text-align: left;\"><a href=\"https:\/\/polieco.com\/en\/prodotti\/cavidotti-750-n-enel\/\" target=\"_blank\" rel=\"noopener\">ENEL cable conduit<\/a>: grey outside, yellow inside;<\/li>\n<li style=\"text-align: left;\">TELECOM cable conduit: blue inside and outside.<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><a class=\"button button-darker\" href=\"https:\/\/polieco.com\/en\/prodotti\/cavidotti-450-n\/\" target=\"_blank\" rel=\"noopener\">Polieco cable conduits<\/a>\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 <a class=\"button button-darker\" href=\"https:\/\/polieco.com\/en\/prodotti\/cavidotti-750-n-enel\/\" target=\"_blank\" rel=\"noopener\">ENEL cable conduits<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>As regards cable conduits, there are no regulations determining what the colour of corrugated pipes should be.
