The photograph at https://telecoms.com/523016/openreach-shaves-10m-off... actually shows someone holding an EV Vehicle plug for single or three-phase charging, rather than something to do with a 'subtended headend' !!!
Cheers!
Haha. That's called a "Type 2" connector.
It's the now standard connector used to connect EVs (both here, across Europe and also Australia/NZ) to an AC power source. Or more correctly called EVSE (electric vehicle supply equipment) rather than "chargers".
These plug connectors can handle both single and polyphase AC supply to the vehicle, depending on the EVSE and the vehicle.
Perhaps editorial was getting confused with the story around BT doing a pilot study to potentially convert their (to be) FTTC disused street cabs to EVSE charge points.
