... supply is given to those heavy consumer whose demand is 11 kV. For heavier consumer (at large scale) their demand is about 132 kV or 33 kV, they take electric supply from secondary transmission or primary distribution and then step down the level of voltage by step-down transformers in their own sub ...

History of electric power transmission
The history of the technology of moving electricity far from where it was generated dates from the late 19th century. This includes movement of electricity in bulk (formally referred to as ""transmission""), and the delivery of electricity (""distribution"") to individual customers. The distinction between the two terms did not exist in early years and were used interchangeably.
