Conduit is hard plastic tubing that completely covers and protects wires or cables used in electrical appliances that need protection from sunlight and other elements. These tubes are generally used through walls, under driveways to make way for the wires.
Installing a good solar conduit is necessary to protect wires from exterior and interior elements that could wet the wires. If wires get wet, they would corrode and eventually damage the power system extensively.
The different materials used for manufacturing electrical conduits are:
- Metal: Different types of steel and aluminum are used in many different versions of metal conduits. Steel conduits are used in commercial and industrial construction. Industries which use large amounts of water and cleaning chemicals install aluminum conduits. Aluminum cannot be directly installed into concrete, so these conduits are painted with materials which prevent corrosion.
- Non-metal: PVC is the most common non-metallic conduit because of its light weight and low cost. Most of the various fittings made for metal conduit are also available in PVC form. This plastic material resists moisture and many corrosive substances. An extra grounding conductor must be pulled into each conduit because of its non-conductive property. These tubes are heated and bent by using special tools designed for this purpose. Two tubes are joined with the help of slip on solvent welded connections. These connectors set up rapidly after assembly and gain strength in a day. Care should be taking while installing PVC underground in multiple or parallel configurations, as mutual heating of cables would deform the conduits.
