BS 5347:1976

This standard BS 5347:1976 Specification for silicon-iron strip-wound cores for use in transformers and inductors for telecommunications and electronic equipment is classified in these ICS categories:

• 29.180 Transformers. Reactors
• 29.100.10 Magnetic components

This British Standard specifies strip-wound cores in both single- and three-phase forms of construction having rectangular cross-sections and rectangular windows (coil spaces). They are manufactured from cold-reduced grain-oriented silicon-iron alloy strip, 0.10 mm and 0.28 mm to 0.35 mm thick and are for use in transformers and inductors for telecommunications and electronic equipment.

Dimensions, magnetic characteristics and electrical performance of single-phase and 3-phase cores. Test methods and inspection requirements included.
