Here's a classic 230/400 V overhead line with a overhead house supply near my home village Darfeld.

They are rare today (30 years ago almost every House had a power supply like the in small villages), even in the 90's there are such supplies.

Today most residents are connected with underground cables or with insulated overhead lines (they will be replaced by underground cables in the future).

In the back is also a 10KV-Power line.
