Finish
Cores can be impregnated
with araldite of various grades depending on application requirements.
Cores can also be insulated with polypropylene vacuum wrapping, the
application of plastic end caps in normal or high temperature grades
or by coating them with epoxy resin powder.
Testing
All items are tested
for their electromagnetic performance. Tests are usually carried out
for M089-27N (M4) 1.5T @ < .37 At/cm and for M111-30P ( M1) 1.8T
@ < .8At/cm but this can be changed to any point on the curve to
meet customer requirements.
Standards
All production is in accordance with the requirements of the following British Standards;
- BS EN 10303:2001 - Thin magnetic steel sheet and strip for use at medium frequencies.
- BS 5935:1980 - Toroidal strip wound cores made of magentically soft material.
