Which type of winding is commonly used in core-type transformers?
-
A.
Disk winding
-
B.
Cylindrical winding
-
C.
Helical winding
-
D.
Sandwich winding
Correct Answer:
B. Cylindrical winding
Explanation:
Cylindrical windings are the preferred choice for core-type transformers, particularly for low-voltage applications. This design involves winding conductors in a continuous helical or spiral pattern around the core legs, often using multiple layers to achieve the necessary turns. Their structural simplicity and efficiency in managing low-voltage requirements make them a standard component in these transformer configurations.
