220 kV Cable Straight Length GIS Termination

[Power0020]

The HV power cables usually require a straight length around joints. I understand the same is required for GIS terminations as well before it starts to bend. I couldn't find any clue about that, any idea?

IMO the actual straight length of the cable is stated by termination manufacturer, as a part of accessories is connected with. For instance, on the attached sketch of Raychem 145 kV termination the C dimension includes gland and sealing part. I think the dimensions correspond to IEEE 1300 or IEC 60859 [which a have not with me].
