Tsab ntawv xov xwm no qhia txog kev paub txog kev lag luam txog Kev Tiv Thaiv Nyiaj Plated los ntawm ntau qhov kev xav, suav nrog cov khoom siv, cov txheej txheem tsim khoom, kev ua tau zoo, cov qauv ntsuas, cov ntawv thov, thiab kev yuav cov ntsiab lus tseem ceeb, los pab cov neeg yuav khoom thiab cov neeg ua haujlwm engineering sai nkag siab thiab xaiv cov khoom tsim nyog.
Cov ntaub ntawv hauv paus ntawm Silver -Plated Contacts
Nyiaj yog cov khoom siv hlau uas tshwm sim thaum muaj hluav taws xob siab tshaj plaws (63 × 10 ^ 6 S / m), qhov siab tshaj plaws thermal conductivity (429 W / m·K), thiab tsis tshua muaj kev sib cuag (tsawg dua 0.1 mΩ). Silver plating ntawm qhov chaw sib cuag tuaj yeem txhim kho lawv cov hluav taws xob kev ua tau zoo thiab oxidation tsis kam.
Common substrates muaj xws li:
1. Copper thiab tooj liab alloys (xws li tooj dag thiab phosphor bronze):Muab cov nqi nruab nrab, siab mechanical zog, thiab zoo heev processability, haum rau nruab nrab thiab tsawg tam sim no daim ntaub ntawv.
2. Nickel thiab nickel alloys:Muab cov corrosion zoo heev thiab hnav tsis kam, haum rau qhov chaw tshwj xeeb.
3. Tungsten- tooj liab alloy:High -kub tsis kam thiab muaj zog tsis kam rau vuam, feem ntau siv rau hauv switchgear raug siab tam sim no surges.
Cov txheej thickness feem ntau yog li ntawm 5 μm mus rau 20 μm. Thickness thiab hardness yuav tsum tau sib txawv nyob ntawm seb ib puag ncig daim ntawv thov, raws li cov qauv xws li IEC 61074 thiab ASTM B700. Rau siab - av av thiab ib puag ncig corrosive heev, txheej txheej thickness tsawg kawg yog 10 μm raug pom zoo.
