Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Isn't there a system that allow for ice melting by making pass a high frequency current through the cable?

As the cable impedance depends on frequency, increasing with frequency, even a low high frequency current results in heating the cable, without having to apply a high voltage.

I remember someone talking about that but I can't recall if it was applied on train catenaries.
