Outside Electrical Wire Types - Percent conduit has long been taken into consideration the lightest in weight as compared to metal conduit substances, and generally lower in cost than other kinds of conduit.[3] in north american electric exercise, it's miles available in 3 different wall thicknesses, with the skinny-wall variety simplest suitable for embedded use in concrete, and heavier grades suitable for direct burial and exposed paintings. Most of the numerous fittings made for steel conduit are also to be had in p.C shape. The plastic cloth resists moisture[4] and lots of corrosive materials, but for the reason that tubing is non-conductive a further bonding (grounding) conductor must be pulled into every conduit. % Conduit may be heated and bent within the field, by way of using special heating tools designed for the reason. Some types of conduit are permitted for direct encasement in concrete. That is normally used in business buildings to allow electrical and communication retailers to be hooked up in the middle of huge open regions. As an instance, retail show cases and open-workplace regions use ground-mounted conduit bins to attach strength and communications cables.

Joints to fittings are made with slip-on solvent-welded connections, which set up rapidly after meeting and acquire complete electricity in approximately sooner or later. Considering that slip-in shape sections do no longer need to be rotated during meeting, the special union fittings used with threaded conduit (which include ericson) aren't required. Given that % conduit has a higher coefficient of thermal enlargement than different kinds, it should be mounted to permit for enlargement and contraction of each run. Care have to be taken while installing p.C underground in multiple or parallel run configurations because of mutual heating effect of densely packed cables, because the conduit will deform whilst heated. Innerducts are subducts that can be established in current underground conduit structures to offer easy, non-stop, low-friction paths for putting optical cables, that have incredibly low pulling tension limits. They provide a means for subdividing traditional conduit that was at first designed for unmarried, large-diameter steel conductor cables into multiple channels for smaller optical cables.

Aluminum conduit, similar to galvanized metal conduit, is a inflexible tube, commonly utilized in business and industrial packages in which a better resistance to corrosion is needed. Such locations could encompass meals processing flowers, wherein big quantities of water and cleaning chemical substances could make galvanized conduit incorrect. Aluminum can not be directly embedded in concrete, since the metal reacts with the alkalis in cement. The conduit may be coated to save you corrosion with the aid of incidental contact with concrete. Aluminum conduit is commonly lower value than steel similarly to having a lower exertions cost to put in, since a period of aluminum conduit will have about one-1/3 the weight of an equally-sized inflexible metal conduit.[2].
