temperature rise inside MV SWGR

temperature rise inside MV SWGR

(OP)
Hi, Fellows,

I am working on a project on which I have to calculate actual cable ampacity in order to decide overlaod setting of the cable.
But I am not sure about the normal temperature rise inside MV SWGR. Does it affect cable ampacity if the cable is run partly inside SWGR?
Based on CEC, if the length of portion with lower ampacity exceeds 10%. The overal ampacity should be consider acoording to lower portion of the cable.

Does anybody here have any experience about this?

Thank you in advance.
