Bunch Stranding: This type of stranding has any number of strands bunched together and twisted in the same direction. This is a reliable construction but doesn't have as high-quality extrusion as other constructions. This method is the lowest costing or cheapest type of stranding that's currently available. A similar construction called smooth bunch stranding has helped solve major issues by arranging the strands in a geometric configuration. |
| Unidirectional Concentric: This stranding configuration has multiple layers of helically laid strands with the same direction of lay. The lay lengths also increase with every succeeding layer. |
| Unilay: This stranding configuration has multiple layers of helically laid strands with the same direction of lay. This stranding also has the same lay length as all succeeding layers. |
| True Concentric: A single central strand that is surrounded by layers of helically laid strands. Every layer has a reversed lay direction with increasing lay lengths for every succeeding layer. |
| Equilay: A single central strand that is surrounded by layers of helically laid strands. Every layer has a reversed lay direction with the same lay lengths for every layer. |
| Rope: A rope standing is any type of stranding (Bunch, Unicentric, etc.) grounded into a large cable. This construction is used in order to create a very flexible conductor. |
