BDFW 40.5KV 16000A Big Current Oil Filled Transformer Bushings

Description

Porcelain Transformer bushing / Insulator  In electric power, a bushing is a hollow electrical insulator that
allows an electrical conductor to pass safely through a conducting
barrier such as the case of a transformer or circuit breaker
without making electrical contact with it. Bushings are typically
made from porcelain; though other insulating materials are also
used.  A basic porcelain bushing is a hollow porcelain shape that
fits through a hole in a wall or metal case, allowing a conductor
to pass through its center, and connect at both ends to other
equipment. Bushings of this type are often made of wet-process
fired porcelain, which is then glazed. A semi-conducting glaze may
be used to assist in equalizing the electrical potential gradient
along the length of the bushing.   
The two most common types of bushings used on transformers as main
lead entrances are solid porcelain bushings on smaller transformers
and oil-filled condenser bushings on larger transformers.  


The types of bushing are as follows:-  

1. Porcelain insulator bushing used upto 40.5 KV.
2. Oil filled bushings consisting of a hollow porcelain cylinder of special shape with a hollow tube shaped conductor through its centre used for the voltage above 40.5 KV.
3. Capacitor type bushing made of thick layers of bakelized paper alternating with thin graded layers of tin foil being covered by a porcelain rain shed and filled up with bitumen in the annular space between the rain shed and the bushing used in outdoor sub-station for the voltage above 40.5 KV.
