BS 5935 covers the dimensional and constructional characteristics for toroidal cores wound from strips of magnetically soft steel or alloy having a thickness of between 0.003 mm and 0.35 mm. BS 5935 includes standard ranges of main dimensions and recommendations for strip thickness, core protection, marking and packing.
BS 5935 on toroidal strip-wound cores is useful for:
BS 5935 provides us with specifications for toroidal strip -wound cores of magnetically soft material so as to make equipment using these cores more efficient. BS 5935 provides terms and definitions of those terms to make it easier to understand the standard.
BS 5935 also provides dimensional characteristics of the plain cores, materials and strip thickness, standard width of the strips and standard core size.
Best practice guidelines for protection, packing and marking of toroidal strip wound cores are also mentioned in the standard BS 5935.
