Aluminum Electrical Conduits

An aluminum conduit is a rigid conduit commonly used in commercial and industrial applications. These types of electrical conduits are used to prevent corrosion and are the preferred conduit used in areas where large amounts of water and corrosion-prone areas. Aluminum cannot be directly embedded in concrete since the metal reacts with the alkalis in cement however it might be protected with additional coatings to prevent concrete from affecting the conduit.

It is normally used in concrete slabs or walls.

The Most Common of All Electrical Conduits

PVC is the lightest conduit material and usually the most affordable type of conduit. PVC pipes can vary in thickness depending on the uses and where the PVC will be installed. The PVC conduit resists moisture and corrosion but the tubing is non-conductive an extra grounding conductor must be passed into each conduit. PVC conduit has a higher thermal coefficient of expansion allowing the conduit to expand and contract. Be aware the installing PVC underground in multiple or parallel run configurations, mutual heating might cause problems on cable performance.
