Thaum tooj liab tsis ua haujlwm
| Qhov xwm txheej | Vim li cas Tsis |
|---|---|
| Sab nraum zoov installation | Los nag, av noo, thiab kub cycles ua rau corrosion |
| Ntug hiav txwv / ntsev cua | Ntsev accelerates corrosion - ntsuab patina cov ntaub ntawv sai sai |
| Kev lag luam ib puag ncig (chemicals) | Acids thiab gases tua tooj liab |
| High humidity (>80%) | Moisture + oxygen=corrosion |
| Ntev - lub sij hawm cia | Cov tooj liab liab oxidizes lub sijhawm |
Yog tias koj lub tsheb npav yuav raug ntsia sab nraum zoov, ze ntawm ntug dej hiav txwv, lossis hauv ib puag ncig kev lag luam, tsis txhob siv tooj liab liab. Koj xav tau tin plating lossis epoxy txheej.
Tin Plating
Tin plating yog electroplated tin (3-8 microns tuab) siv rau cov tooj liab busbar tom qab tag nrho cov fabrication tiav.
Vim li cas Tin Plating yog tus qauv
| Qhov zoo | Vim Li Cas Nws Tseem Ceeb |
|---|---|
| Tus nqi qis | Tsuas yog 5-10% premium tshaj tooj liab liab |
| Zoo corrosion kuj | Tiv thaiv cov av noo, tshuaj me me |
| Tswj conductivity | Tin yog conductive - tsis muaj ampacity poob |

| Lubricity zoo | Ua haujlwm zoo rau zawv zawg tiv tauj (disconnect keyboards) |
| Corrosion resistant (nruab nrab) | Zoo tshaj tooj liab liab, phem tshaj tin |
Disadvantages ntawm Silver Plating
| Qhov tsis zoo | Yam Koj Yuav Tsum Paub |
|---|---|
| Tus nqi siab | 20-30% ntau tshaj tin plating |
| Tarnishes | Silver reacts nrog sulfur hauv huab cua - tig dub |
| Tarnish yog conductive | (Tsis zoo li txhuas oxide, nyiaj sulfide tseem ua) |
| Tsis yog rau vuam | Yuav tsum tau muab tshem tawm ua ntej welding |
Technical Specifications
| Parameter | Tus nqi |
|---|---|
| Plating thickness | 5-15 microns (tus qauv) |
| Tiv tauj tiv thaiv | <1 mΩ (much lower than tin) |
| ntsev tsuag kuj | 48-72 teev (tsawg dua tin) |
| Ua haujlwm kub | Mus txog 200℃(nyiaj melts ntawm 962 degree) |
Thaum xaiv Silver Plating
| Daim ntawv thov | Vim li cas Silver Plating |
|---|---|
| Siab -frequency busbars (RF, RF) | Cov nyhuv ntawm daim tawv nqaij - silver's low resistance matters |
| EV roj teeb connectors | Tsis tshua muaj kev tiv thaiv rau cov dej ntws siab |
| Tshem tawm cov keyboards | Kev sib cuag zawv zawg yuav tsum muaj lubricity |
| Cryogenic kev siv | Silver ua tau zoo ntawm qhov kub thiab txias |
| Precision ntsuas | Kev tiv thaiv kev tiv thaiv yuav tsum raug txo kom tsawg |
Rau feem ntau tus qauv switchgear, nyiaj plating yog overkill. Tin plating yog txaus thiab ntau pheej yig dua. Tsuas yog qhia nyiaj plating yog tias koj xav tau qhov kev tiv thaiv qis tshaj plaws.

FAQ
Q1: Kuv puas tuaj yeem siv tooj liab busbar sab nraum zoov?
Tsis pom zoo. Cov tooj liab liab sab nraum zoov yuav corrode - tsim patina ntsuab. Thaum lub patina tseem ua tau zoo, nws zoo li tsis zoo, tuaj yeem tawg tawm, thiab thaum kawg tuaj yeem txo tus ntoo khaub lig- ntu hauv qhov chaw hnyav.Rau kev siv sab nraum zoov, qhia tin plating (yam tsawg kawg) lossis epoxy txheej (zoo tshaj). Rau cov ntug dej hiav txwv lossis dej hiav txwv, epoxy txheej yog pom zoo.
Q2: Dab tsi yog qhov txawv ntawm tin plating thiab nyiaj plating?
Tin plating nqi tsawg dua (5-10% hwm tshaj tooj liab liab) thiab muaj kev tiv thaiv corrosion zoo. Cov nyiaj plating raug nqi ntau dua (20-30% ntau dua li cov tin) tab sis muaj qhov qis tshaj qhov ua tau tiv thaiv.Rau feem ntau switchgear, tin yog txaus. Siv nyiaj rau siab - daim ntawv thov zaus (cov nyhuv ntawm daim tawv nqaij), zawv zawg tiv tauj (disconnect switches), los yog qhov chaw tiv thaiv yuav tsum tau txo kom tsawg.
Q3: Puas yog tin -plated tooj liab busbar xeb?
Tin tsis "xeb" (hlau oxide), tab sis nws tuaj yeem corrode. Tin plating muab kev tiv thaiv corrosion zoo - feem ntau yog 96+ teev hauv kev tshuaj ntsuam ntsev tsis muaj xeb liab.Nyob rau hauv ib puag ncig hnyav (nqaij ntug dej hiav txwv, tshuaj lom neeg), tin yuav kawg corrode. Rau cov cheeb tsam no, hloov mus rau epoxy txheej. Rau kev siv sab hauv tsev, tin plating kav ntau xyoo tsis muaj teeb meem.
Q4: Dab tsi yog qhov sib txawv ntawm cov cua sov shrink tubing thiab epoxy txheej?
Thaum tshav kub kub shrink tubing yog ib tug polymer raj shrunk mus rau lub busbar - uas tsis muaj nqi, yooj yim mus thov, tab sis tsuas yog ua hauj lwm ntawm ncaj seem (tsis muaj khoov). Epoxy txheej yog txau los yog dipped - tus nqi siab dua, kev pabcuam tag nrho suav nrog khoov, siab dua dielectric zog, thiab UV tiv taus.Rau cov busbars ncaj nraim xav tau rwb thaiv tsev, cua sov shrink yog zoo. Rau kev khoov busbars lossis siv sab nraum zoov, epoxy txheej yuav tsum tau ua.
Q5: Dab tsi yog tus qauv plating thickness rau tin thiab nyiaj?
Tin plating: 3-8 microns tus qauv (10+ microns rau lub luag haujlwm hnyav). Nyiaj plating: 5-15 microns txheem.Thicker plating nqi ntau dua thiab ntxiv sij hawm ua hmoov txhuas. Cov ntawv thov feem ntau tsis xav tau plating tuab dua li tus qauv. Peb ntsuas thickness siv XRF thiab muab ib daim ntawv qhia nrog txhua yam khoom xa tuaj.
Q6: Nyiaj-plated tooj liab busbar tig dub. Qhov no puas yog qhov teeb meem?
Tsis yog - nyiaj tarnish (silver sulfide) tseem ua tau. Qhov no yog ib qho kev txhawj xeeb, tab sis tarnish tsis cuam tshuam rau hluav taws xob ua haujlwm.Tsis zoo li txhuas oxide (uas yog ib qho insulator), nyiaj sulfide ua hluav taws xob. Yog tias qhov tshwm sim tseem ceeb, qhia txog kev tiv thaiv - kev kho mob tarnish (muaj raws li kev thov). Rau feem ntau daim ntawv thov, tarnish tsuas yog cosmetic xwb.
Q7: Puas yog qhov chaw ua tiav puas cuam tshuam rau tooj liab busbar ampacity?
Tsis yog - liab qab tooj liab, tin plating, thiab nyiaj plating muaj qhov tseem ceeb tib yam ampacity.Cov txheej txheej plating yog nyias (3-15 microns) thiab ua tau zoo heev. Thaum tshav kub kub shrink tubing thiab epoxy txheej DO txo ampacity vim lawv cuab cua sov. Rau insulated busbars, derate ampacity los ntawm 10-15% (heat shrink) los yog 15-20% (epoxy txheej). Saib pebCopper Busbar Ampacity Guidekom paub meej.
