Zusammenfassung:	A subsea electrical device has a penetrator extending through a housing for the connection of a motor lead cable supplying electric power or electric signals. The penetrator has a glass or glass-ceramic body sealed to the housing. A connector, such as a pin connector, extends through the glass or glass-ceramic body. The motor lead cable connects to one end of the connector while the other end of the connector allows for the transfer of the electric power or electric signals to the components within the housing. The glass or glass-ceramic body withstands the high pressure and harsh environment of the subsea atmosphere, allowing for the long term us of the electrical device without need for replacement due to failure of the penetrator.
