What is the difference between Bushing well BW150R and BW150F?

1. What are bushing wells?

The bushing well terminates the transformer's primary winding leads at the tank wall. On the air-side of the transformer, the bushing well mates with all bushing inserts which meet the applicable sections of ANSI/IEEE Standard 386.

2.What is the difference between Bushing well BW150R and BW150F?

BW150R: 

Eaton Cooper Power series bushing well, Gasket included, HTN, 35 kV, Phase to ground: 21.1 kV, AC 1 min: 50 kV, DC 15 min: 103 kV, BIL: 200 kV, Corona: 26 kV, Removable, 600 A, 2.5 inch, Bulk pack 40

BW150F: 

Eaton Cooper Power series bushing well, Gasket included, HTN, 35 kV, Phase to ground: 21.1 kV, AC 1 min: 50 kV, DC 15 min: 103 kV, BIL: 200 kV, Corona: 26 kV, 600 A, 2.5 inch, Bulk pack 40

The only difference between the two is whether the bolts inside the casing well are fixed or separable，and there is no difference on the surface.

3.What are the advantages of BW150R and BW150F respectively?

BW150R:

The tri-clamp bushing well is high temperature nylon (HTN) molded，and is externally clamped for sidewall mounting on single or three phase transformers filled with transformer oil, or an approved equivalent. It mates with all bushing

inserts meeting applicable IEEE std 386-2016. It’s knurled copper stud with rolled threads provides excellent onductivity.It is also has an optional removable stud that offers easy field replacement of the bushing stud with a standard 5/8" socket wrench in the event of damage or breakage in the field. A 7/64" hex has been provided in the portion of the stud which mates into the bushing insert. Should breakage occur here this feature allows for easy stud removal from the insert.
