Ɛwom sɛ wɔn nyinaa ka krataa a wɔde siw mframa ano no fã de, nanso DMD, DMDM, ne NHN nkrataa a wɔde siw mframa ano no wɔ nhyehyɛe, ne su, ne sɛnea wɔde di dwuma.
1. Dɛn ne DMD Insulation Krataa?
DMD insulation krataa yɛ ade a ɛyɛ mmerɛw a wɔabom ayɛ a wɔdepolyester film ne polyester fiber a ɛnyɛ-ntama a wɔanwene.
Ɛyɛ polyester film a wɔde adhesive akata so na wɔde polyester ntama a wɔanwene ayɛ no fã biako, afei wɔayɛ no kalenda ma ahoɔden ne mmerɛwyɛ ayɛ papa.
2. Nsonsonoe a ɛda DMD ne DMDM ntam
Nsonsonoe a ɛda adi kɛse wɔ DMD ne DMDM insulation krataa ntam ne layers dodow:
DMD=3 nkyerɛwde ahorow
DMDM=4 nkyerɛwde ahorow
Ɛwom sɛ ɛsono sɛnea wɔkan layer no de, nanso nneɛma abien no nyinaa wɔ mfiridwuma ne anyinam ahoɔden a ɛkyɛn so. Wɔde di dwuma kɛse maslot insulation ne liner insulation a wɔde hyɛ muwɔ mfiri ne anyinam ahoɔden mfiri mu, na abien no nyinaa de maAdesuakuw B (digrii 130 ) .ɔhyew a ɛko tia.
3. Dɛn ne NHN Insulation Paper?
Wɔde NHN krataa a wɔde siw anyinam ahoɔden ano di dwuma wɔ nhama, nhama, ne anyinam ahoɔden mfiri ahorow mu. Ɛma insulation adwumayɛ a ɛkyɛn so ne mfiri ahoɔden.
Wubetumi abu NHN no su atɛn denam hwɛ a wobɛhwɛ so:
- Nneɛma a wɔyɛ no ho nsɛm
- Insulation a ɛko tia
- Leakage mprempren
- Electrical su ahorow nyinaa
Sɛ efĩ anaa nsu pii wɔ NHN mu a, ne conductivity kɔ soro, na ɛma leakage current a ɛkɔ soro ba. NHN krataa a ɛyɛ papa-a ɛboa boa ma transformer adwumayɛ tu mpɔn, ɛtew adehwere so, ɛma ahobammɔ ne ahotoso yɛ kɛse, na ɛtew ne yɛ ho ka so.
NHN insulation krataa no yɛ kɛse de di dwuma wɔ motors ne generators maslot wedge insulation, phase a ɛbɔ ho ban, awiei laminations, ne nneɛma afoforo a wɔde bɔ wɔn ho ban. Ɛboa ma ɔhyew a ɛko tia, mfiri ahoɔden, ahobammɔ, ne mfiri a ɛkyinkyini no nkwa nna nyinaa tu mpɔn.
