Acoustic shielded hlau: nta thiab hom

Yuav kom ua tau high-zoo suab thaum koj nruab ib lub suab system, koj yuav tau them sai sai rau tag nrho cov Cheebtsam - hais lus, amplifiers, thiab, ntawm chav kawm, cov lus qhia cables. Tau zoo suab txawm los ntawm cov kim system yuav tsis ua hauj lwm yog tias koj siv ib tug dog dig hlau. Shielded cable - tias yog dab tsi koj yuav tsum sib txuas lus nrog rau qhov chaw teeb liab playback pab kiag li lawm. Txwv tsis pub koj thiab kuv yuav tsum mloog suab nrov nyob rau hauv lub so ntawm zaj nkauj.

hais lus cable

Niaj hnub nimno hais lus cable yog ib tug ob los yog ntau tshaj conductors ntawm hluav taws xob tam sim no, muab tso rau hauv lub rho tawm ntawm polyvinyl tshuaj dawb, teflon, polyurethane thiab lwm yam polymeric cov ntaub ntawv. Cov nyob ntawm tej yog electrically zoo tib yam, tab sis yog cim los ntawm cov xim txawv, yog li ntawd cov neeg siv tsis rov qab tus polarity thaum lub sij hawm ntawm kev twb kev txuas, kev koom ua ke ntawm pab kiag li lawm. Tooj liab ua hauj lwm pab raws li ib lub hauv paus khoom. Nws muaj tus nqi qis tshaj hluav taws xob resistivity uas tso cai rau mus cuag siab suab zoo. Txawm li cas los, thaum lub sij hawm tso ntawm lub cable tej zaum yuav kis tau nyob ze hwj chim kav. Vim hais tias ntawm no magnetic teb yuav tshwm sim, eddy currents, uas zoo heev txo lub suab zoo.

Kom tsis txhob no qhov teeb meem, siv ib tug tshwj xeeb hlau - shielded. Xws li ib tug cable muaj ib tug tshwj xeeb kev tiv thaiv ntawm hlau los yog yas, uas yog ib yam ntawm cov "screen" tiv thaiv electromagnetic cuam.

Hom ntawm hais lus cables

Yuav kom ib tug dog dig shielded hlau tiv nrog kev tiv thaiv los ntawm cuam tshuam, nws yuav tsum tau kev cob cog rua rau hauv av, piv txwv li hauv av. Nyob rau hauv tej rooj plaub, qhov kev txiav txim yog tsuas tsis yooj yim sua. Uas yog vim li cas twb coined kuas cable. Yog hais tias nyob rau hauv lub qub neeg xyuas pib yog tam sim no tsuas yog ib qho central "tub ntxhais" uas yog lub ntsiab lub teeb liab, ces ob tug ntawm lawv nyob rau hauv kuas cable - kub thiab txias. Nkawd ob leeg nqa cov lus, tiam sis muaj ntau "kev zoo sib thooj". Cov hauj lwm zoo ntawm no yog nyob rau qhov nqi koj tshuav txoj kab ntawm rods.

Muaj zoo kev pab tiv thaiv Star Quad cables, nyob rau hauv uas ob khub ntawm "rods" raug rho tawm thiab kev cob cog rua nyob rau hauv thaum uas tig mus nrog txhua lwm yam, thiab qhov no yog tiav los ntawm ib theem siab ntawm kev tiv thaiv. Kws txawj qhia thiaj li hu ua conductive hlau shielded nrog yas. Qhov no hom ntawm cable yog zoo tshaj luv luv mus, piv txwv li, thaum lub sij hawm installation nyob rau hauv lub tsheb suab system.

Nyob rau hauv ib tug nyias muaj nyias ib pab pawg neeg yuav paub qhov txawv microphone cables, nyob rau hauv uas tus tiv thaiv yog ua los ntawm ib tug woven cov ntaub ntawv uas. Tab sis qhov tseem ntau yam thiab muaj qhov zoo tshaj plaws kev tiv thaiv yog ib tug hlau nrog ib tug foiled screen.

Nyob ntawm tej nrog ntawv ci tiv thaiv

Cables nrog ntawv ci tiv thaiv ntawm ib tug txawv cov ntaub ntawv uas los ntawm uas qhov kev tshuaj ntsuam raws li zoo raws li lub hom braid. Nyob rau hauv tag nrho muaj cov plaub hom electromagnetic tiv thaiv:

• tooj liab ci los sis txhuas screen - muab tiv thaiv zoo conductors ntawm electromagnetic cuam tshuam, tab sis yog raug rau quav rotations (tiv thaiv so thiab tej kab nrib pleb);
• tooj liab mesh braid - ib tug hlau, ib tug shielded nyob rau hauv no txoj kev, tsim qhov zoo tshaj plaws kev tiv thaiv tiv thaiv cuam tshuam, tiam sis muaj ib tug heev tus nqi (siv nyob rau hauv kev khoom);
• muab kauv braid ntawm tooj liab los yog lwm yam puag co - ib tug cable tsis yog raug rau cov neeg kho tshuab puas thiab zoo tiv thaiv tawm tsam cuam.

Qhov thib plaub hom yog cov cable nrog ib tug ua ke screen, uas muab qhov tseem ceeb thaj chaw ntawm ib tug khoom ntawv ci, thiab ntau hom braids. Lawv txawv nyob rau hauv qhov nruab nrab nqi, thiab ib tug loj assortment ntawm theem ntawm kev tiv thaiv.

Kuj ntawm tus neeg xyuas pib thiab suab zoo

Decisive cawv rau lub suab zoo muaj ib tug meej hluav taws xob kuj tus neeg xyuas pib. Kab acoustic kuj yog nyob ntawm ntau tsis - cov khoom, tus ntoo khaub lig sectional cheeb tsam thiab ntev ntawm lub cable. Qhov zoo tshaj plaws zoo ntawm lub suab yog muaj peev xwm muab ib tug tooj liab hlau thiab ib tug shielding ntawv ci. Yog li nyob rau hauv lub rwb thaiv tsev txheej yuav tsum muaj tsawg kawg yog 20 strands. Yog hais tias ntau tus ntoo khaub lig-sectional tsam tsis pub tshaj 2.5 hli ^2, thiab cov cable ntev yog tsis pub dhau 3 meters, ces cov kuj yuav ua ncaj rau zero. Raws li, lub suab zoo nrog ib tug hlau yuav zoo tshaj plaws.

neeg xyuas pib tsis muaj feem nyob rau hauv cov cuab yeej siv. Piv txwv li, ntev nyob ntawm tej muaj lub siab capacitance thiab inductance, uas tsim ib tug ntxiv load rau hauv lub amp.

interconnect cables

Interconnect cable yog ib tug neeg xyuas pib, qhov xaus ntawm uas muaj kev tshwj xeeb connectors rau kev twb kev txuas rau cov khoom siv los yog mus rau lub blocks. Shielded interconnect cables, nyob ntawm tej muaj ib co piv rau pa acoustic kab. Nyob rau hauv kev, lub suab zoo tsis yog nyob rau hauv lub hom kws muaj txuj ci, thiab qhov siv thiab ua cov ntaub ntawv. Txiav txim seb cov ntaub ntawv uas tej zaum yuav lub labeling:

• SSS HI KAWG SP - denoted li acoustic kab ua los ntawm tooj liab plated nrog nyiaj, muaj peev xwm sawv ntawm kev tsim qhov zoo tshaj plaws zoo ntawm lub suab.
• EMT ofc sc - ib tug tsiaj ntawv siv rau denote nyob ntawm tej ofc cia li ua tsis tau zoo rau yav dhau los cov neeg sawv cev ntawm lub kis lub teeb liab zoo.
• AHpsc 16 GA - tsuas high-zoo nyob ntawm tej.

Yog hais tias koj tab tom nrhiav rau cables, muaj peev xwm ntawm tsis muaj distortion mus rau kis ib lub teeb liab, ces koj yuav tsum xyuam xim rau cov khoom ua nkaus ntawm cov nyiaj. Tej khoom muaj nqis pua pua ntawm cov nyiaj rau ib 1 'meter', tab sis qhov zoo tshaj ntawm lub teeb liab kis tau los ntawm lawv muaj peev xwm tsis muab piv.

tso tseg ntawm tej

Ib tug tshwj xeeb qhov chaw nyob rau hauv kev ua lag luam ntawm acoustic khoom siv shielded hlau tso tseg. Qhov no neeg xyuas pib nyob rau hauv lub rwb thaiv tsev txheej yog ob peb intertwined strands. Lawv muaj ib tug xov tooj ntawm zoo dua ib leeg-core cable:

1. High elasticity - cov nyob ntawm tej yog tsis txaus ntshai excesses, koj lem thiab lwm yam cov neeg kho tshuab los.
2. Me tam sim no losses - vim lub teeb liab kis tau tus mob los ntawm ob peb lub "pas nrig".
3. High switching - cov txheej txheem uas tshwm sim nyob rau hauv thawj lub vib nas this tom qab lub luv luv Circuit Court (thaum switching lub toggle mus, piv txwv li) muaj tsis ntxim.
4. High cia siab rau thiab ntev lub neej - lub neej ntawm tej khoom yog ntau ntau tshaj ib leeg-core.

Qhov no hom ntawm cables muaj tej yam tsis zoo. Chief ntawm lawv - tus nqi. Yog li, tus nqi rau ib tug shielded ob-hlau kab tej zaum yuav mus txog 1500 rudders. Nyob rau hauv tas li ntawd, cov ntawm yog tsis npaj rau kev siv nyob rau hauv high-zaus tes hauj lwm.
