Oil Filled Cables

Pothead.

I'm not sure about refilling it.

Potheads are seldom oil filled in my area (USA). There are filling compounds with varying properties, everything from petrolatum to Ozite.

It's a cable sealing end or seal end. The oil is usually an inhibited mineral oil but exotic oils are sometimes encountered encountered.

Thanks everyone.

"Pothead" is a bit informal in my experience. "Terminator" is more likely to be what you'll see in a catalog. If oil filled, be sure to test for PCB.

My company uses "pothead" as the formal name for the above pictured device.

In denser urban environments where a similar but larger scale buried device is used as the interface between a high- or low-pressure oil-filled pipe-type cable and where the individual phases of the cable enter a tranformer station, my company uses the term "trifurcator," with single-phase potheads serving as the typical transition point between the cable and the indoor [or, where space allows, outdoor] air-insulated buswork. These potheads are sometimes compound-filled, sometimes oil-filled.

Yeah, Terminator
