| Calculation based on recommended taping angle 45° and overlaping 50%. More tape width calculation formula as below: | |||||||
d——Conductor diameter （mm)
t——Tape thickness （mm）
k——Overlapping ratio （%）
α——Taping angle （°）
b——Tape width （mm）
Smaller taping angle increases the taping efficiency but at expense of conductor wrapping tightness which affects negatively for insulating property and extrusion. Recommended taping angle for lowest friction on tape is 45°(+/-5°).
According to different supporting materials, Firwo®-S synthetic mica tape include below mentioned three types: synthetic mica tape with single side glass fabric, synthetic mica tape with double sides glass fabric and synthetic mica tape with glass fabric and film backed. for the same thickness of different types, synthetic mica tape with single side glass fabric has the most excellent fire-resistant properties due to its higher mica content, but more carefully operation and better taping equipment are required.
Due to halogen Fluorine contented by synthetic mica, Firwo®-CM calcined muscovite mica tape is recommended to substitute synthetic mica tape for application of cables with strict requirement of halogen free.
