What is the difference between a conventional head and an elbow of a high voltage cable? - Newheek X ray Cable

What is the difference between a conventional head and an elbow of a high voltage cable?

Today I received the question: What is the difference between the two types of high-voltage cables, the conventional connector and the elbow? I checked the data and made a comparison and analysis.

Length of voltage cable
High-voltage cable structure: according to the arrangement of the center line, there are two kinds of coaxial (concentric circle) and non-concentric (non-concentric circle) joints, but the two joints are the same except for the appearance of the different.
In addition, attention should be paid to the use of high-voltage cables.
(1) when using cable, the bending radius should not be less than 66mm.
(2) cable usage temperature: -40 C ~70 C.
(3) cable rated voltage: 75KVdc
