As base film we use a biaxially oriented, high temperature resistant film made of Polyethylene naphthalate.
Due to the high mechanical, thermal and electrical properties this film is usable for high voltage applications in a temperature range of > 125°C.
The film is metalizable with pure aluminum (99.98 %), zinc or zinc-aluminum alloy.
Here are our standard kinds of metallization available:
Other designs like multiple internal series, step, tapered and segment metallization and many others on request.
|HVMAD||Aluminum Metallized double side|
|HVMAR||Aluminum Metallized with Heavy Edge|
|HVMAZR||Aluminum Metallized with Zinc Heavy Edge|
|HVMZR||Zinc Metallized with Zinc Heavy Edge|
|Nominal thickness (μm)||3.0 / 4.0 / 5.0 / 6.0 / 8.0|
|Slitting width||≥ 2.25 mm|
|Free margin||≥ 0.25 mm|
|Inside core diameter||75 mm|
|Roll outside diameter||155 mm / 165 mm / 180 mm / 200 mm / 240 mm|
|Typical properties||temperature resistance > 150°C, high voltage resistance up to 125°C, |
good self-healing properties in compliance with limited winding hardness,
high dielectric constant and good dielectric strength enable small designs for high temperature power capacitors
