This sequence of striking photographs documents the replacement of G&W Electric Co. 2000 MCM 15kV potheads following catastrophic animal damage.

The damaged medium voltage potheads were slowly heated by the Cable Splicer sufficiently to remove the glass, then allowed to cool, so the compound could be chipped off down to the cable gland. The wipe and the cable gland were not removed – there was zero damage to the inside of the 15kV pothead, all damage was located externally.

With the compound removed, to the cable gland, the cable termination inspected and cleaned, a layer of varnished cambric tape over the cable and the void between the aerial lug and cable insulation also filled with VC. Doug comments, “because G&W potheads are manufactured with such advanced precision, all new potheads bolted directly to the gland, and directly back onto the structure perfectly.”

Did you know G&W Electric was founded in 1905 and introduced the first disconnecting porcelain pothead?
