Consequently,​‍​‌‍​‍‌ different electrical devices may call for various kinds of bushing shrouds due to the fact that actual structural differences between the following actual factors: bushing size, terminal structure, wire direction, and installation space may be a reason. Moreover, these characteristics are a determining factor as to whether the sheath could be properly installed and protected, and not just by referring to the name or appearance of the ​‍​‌‍​‍‌equipment.

The polyolefin bushing guard is more suitable for projects with multiple specifications, non-standard size and focus on mechanical protection capabilities, while the transformer bushing cap is more suitable for projects with uniform specifications, long-term outdoor operation, and high requirements for flexibility and weather resistance.
