Elbows are standardized to dimensions of 482x482mm and are available in flat-wise & edge-wise types. Constructionally they are typical to feeder elements with projecting out conductors, suitable for standard joint connections.
Unless unavoidable, flat wise elbows are not recom-mended, as they reduce the current-carrying efficiency of the system, due to 90o bending of the conductors, which results in broken conductor molecules.
Typical Combination elbows - Offsets, Combination & Obtuse elements are designed, where critical site condi-tions does not allow connection of standard elbows. Also depending on project requirement, elbow joints can also be provided to cater to very short length elbow.
