Indeed there are situations where many kind of clamping is used. I think

Thank you, I'll look at those.
Note that power=insulator is dedicated to insulators and other keys like
material can get the insulator material and so on...
It's not exactly what line_clamp intend to describe, see below.

Proposal deals with clamping wires/cables on supports in general.
Insulators are a particular practical mean to do so especially for power
where conductors have to be separated from their supports as to prevent
electricity to go back to earth.
You don't have insulator here :
But it a suspension clamping.
The main point is to remove power dedicated values from tower:type.
As it's better to make it global, such values are extended to portals,
And to make it an order more global, let's not design it specific to power
anymore but suitable for telecom or any other line
That's how line_clamp came to my mind.
Should I update the proposal and rationale chapter?
All the best
