Wɔ anyinam ahoɔden afiri a wɔde siw mframa ano no mu no, Diamond Dotted Insulation Paper (DDP) abɛyɛ nneɛma a wɔde di dwuma kɛse sen biara a wɔde yɛ nneɛma a ɛkorɔn-voltage mfiri no mu biako, esiane ne bonding ahoɔden a wotumi de ho to so ne anyinam ahoɔden adwumayɛ a ɛyɛ den nti. Wɔn a wɔyɛ transformers, motor, ne power distribution systems no, DDP de mfiri a ɛyɛ den ne ahobammɔ a ɛkari pɛ a nneɛma kakraa bi na ebetumi ayɛ pɛ ma.
DDP kyerɛ krataa a wɔde siw nsu ano a wɔde epoxy resin a wɔayɛ no foforo a wɔahyehyɛ no wɔ daimond nsusuwso soronko mu akata so. Below 30℃, saa resin yi kɔ so yɛ dry na ɛnyɛ{2}}Tacky, ma kwan ma wɔde nneɛma no sie, yɛ ho adwuma, na wopira a ɛnyɛ den. Wɔ gua ahorow ne nneɛma a wɔde yɛ nneɛma so no, DDP nso betumi ada adi wɔ din te sɛ presspaper a wɔde diamond ayɛ, krataa a wɔde epoxy adura ho, diamond pattern insulation paper, DPRCP, anaasɛ DDP. - kɛkɛ a ɛkyerɛ diamond koro no ara-aduru a wɔde presspaper a wɔayɛ no sɛ patterned.
1. Nea enti a diamond nsusuwso no ho hia .
Nea ɛnte sɛ nea ɛkɔ so kata so no, wɔde resin a ɛwɔ DDP so no gu diamond nsensanee a ɛwɔ ntam kwan pɛpɛɛpɛ so. Diamond biara taa yɛ bɛyɛ 9.5mm × 9.5mm, na ɛwɔ ntam kwan yɛ 15.9mm.
Saa nhyehyeɛ yi nyɛ afɛfɛdeɛ - Ɛsom dwumadie titire ahodoɔ bi .
hwɛ hu sɛ ngo a ɛkɔ ngo mu no fata-de transformers gu mu .
Ɛma mframa a akyea no guan bere a ɛreyow no .

Ɛma insulation layer no gyina wɔ anyinam ahoɔden nhyɛso ase .
Saa engineered pattern yi yɛ ade titiriw biako nti a wɔpɛ DDP wɔ transformer windings mu.
2. Mfiridwuma & anyinam ahoɔden ahoɔden a wubetumi de wo ho ato so .
Bere a coil no reyow no, epoxy resin no yɛ mmerɛw na ɛyɛ adwuma. Bere a ɔhyew no kɔ soro no, resin no dannan fi ade a wɔde nkata so a ayɛ hyew so kɔ afiri a wɔde sa yare a ɛyɛ den so.
Sɛ wɔsa no yare wie a, nneɛma a ɛbɛn a ɛma mframa bɔ no yɛ nea wɔde mfiri abɔ mu, na ɛyɛ nhyehyɛe a ɛyɛ den a wɔabom ayɛ.
Eyi ma wonya mfaso atitiriw abien:

Ɛhwɛ tenten-Term dielectric ahoɔden ase wɔ anyinam ahoɔden adesoa a ɛkorɔn ase .
Wɔ soro-voltage environments a insulation huammɔdi no yɛ nea ɛho ka yɛ den no, saa bonding adwumayɛ yi ho hia.
3. Adwumayɛ wɔ ɔhyew & ɔhyew ase .

Wɔ nnwinnade a ɛyɛ adwuma wɔ mmeae a ɛhɔ yɛ nwini anaasɛ wim tebea a ɛsakrasakra no fam no, saa gyinabea yi boa ma ɔsom no nkwa nna yɛ kɛse na ɛtew asiane a ɛwɔ hɔ sɛ wobesiesie no so.
4. Ɛnyɛ den sɛ wobɛyɛ, laminate, na woayɛ ho nhyehyɛe .
Ade foforo nti a DDP da so ara yɛ ade a wɔpɛ sɛ wɔde siw mframa ano ne sɛnea ɛyɛ adwuma yiye:
Ɛyɛ nea ɛyɛ mmerɛw sɛ ɛbɛma ayɛ winding a ɛyɛ den .
Ɛnyɛ den sɛ wobetwitwa na wɔayɛ no laminate .
Ɛne nhyehyɛe ahorow a ɛsono emu biara a ɛwɔ insulation mu no hyia .
Wɔn a wɔyɛ te sɛ GBS no ma wonya akwan horow a wɔayɛ ama transformer nhyehyɛe pɔtee bi, na ɛhwɛ ma mfiri ahoɔden a ɛfata ne dielectric adwumayɛ wɔ nhyiam a etwa to no mu.
5. baabi a wɔtaa de DDP di dwuma .
DDP di dwuma titiriw wɔ anyinam ahoɔden mfiri ahorow pii mu:
• Ngo-nsakrae a wɔde ahyɛ mu .
de di dwuma kɛse ma:
Inter-dan HV ne LV windings no ho ban .
Layer insulation wɔ nkyekyɛmu transformer coils mu .
• Ɛkorɔn-voltage motors & anyinam ahoɔden nneɛma .
Ne anti-Corona su ahorow no ma ɛfata ma:

Insulation structures a ɛhwehwɛ sɛ mfiri no gyina hɔ yiye .
6. Sɛnea DDP bata conductors ho bere a winding .
Adhesive a ɛwɔ DDP mu no yɛ adwuma bɛyɛ 90℃. Saa bere yi de, resin no yow, ɛsen, na efi ase bɔ insulation layers no. a ɛyɛ aduru a wɔde sa yare a wɔtaa de di dwuma (sɛ nhwɛso no, .Simma 90 wɔ 90℃.) de resin no si hɔ koraa na ɛma adhesion a ɛyɛ den ba.
Bonding ahoɔden a etwa to no betumi adu 70 psi (≈0.275 MPa wɔ 100℃), hwɛ hu sɛ winding layers kɔ so yɛ fixed mpo bere a transformer no nya mfiridwuma mu ahodwiriw anaa ɔhyew ntrɛwmu.
Nneɛma a wɔyɛ no yiye ho hia yiye.

7. Dɛn na ɛwɔ DDP gua so bo so nkɛntɛnso?
Nneɛma pii na ɛkyerɛ sɛnea DDP insulation krataa no ho ka te:
✔ Nneɛma a wɔde yɛ adwuma .
Base presspaper ne epoxy resin no su nya anyinam ahoɔden adwumayɛ ne ne bo so nkɛntɛnso tẽẽ.
✔ Mfiridwuma a wɔde yɛ nneɛma .
Precision coating, pattern uniformity, ne curing consistency ma adwinnan a ɛyɛ den ne ɛka a wɔbɔ no yɛ kɛse.
✔ Guadi tebea .
Supply/demand cycles taa nya nkɛntɛnso tiawa-bere mu bo nsakrae so nkɛntɛnso.
✔ Brand & Ɛyɛ papa .
Mpɛn pii no, wɔn a wɔyɛ nneɛma a ɛyɛ fɛ no de mfiri ahoɔden a eye, bonding a ɛyɛ pɛpɛɛpɛ, ne ahotoso a wɔde siw ano ma.
Awie
DDP da so ara yɛ ade a ɛho hia a ɛma ahoɔden a wɔde dannan nneɛma, mfiri, ne HV mfiri afoforo. Ne diamond-epoxy nhyehyɛe a wɔayɛ no sɛnea ɛte no ma mfiri no gyina, anyinam ahoɔden ahobammɔ, na ɛware-bere a ɛyɛ den - ne nyinaa ho hia ma nnɛyi tumi nhyehyɛe ahorow.
Sɛ wo dwumadie no fa transformer insulation, motor repair, anaa high-voltage component development ho a, DDP a ɛfata a wobɛpaw no betumi ama ahotosoɔ ne nnwinnadeɛ nkwa nna atu mpɔn kɛseɛ.
