Epoxy Electrical Insulation System
|
JT 8218A Epoxy Resin 100 pbw JT 8218B Epoxy Hardener 20-25 pbw |
|
| Used for:low voltage CT(and zero-sequence instrument transformers) | |
|
electronic components such as: ignition, regulator, electronic transformers, network transformers, pump motor, ignition coil, transformer, negative ion generator, AC capacitor, (vertical, horizontal, cartridge, film capacitor), power module, LED module, insulating pouring lamps etc. Appropriate operation time, easy to produce the work. Can withstand high and low temperature curve, with excellent electrical properties and physical properties.
|
Applications |
|
For common vacuum casting processing, the typical mould temperature is 70℃–80℃, demoulding time( different as per temperature and volume) is about 5-8h. Keeping 10h at 130℃ after curing. Demoulding time and after-curing cycle need to be determined as per specific product design and technology. Please kindly contact our techanicians for more information
