Kodi Cholinga cha Zida Zothandizira pa Chingwe N'chiyani?

Kuti ateteze umphumphu wa kapangidwe kake ndi magwiridwe antchito amagetsi a zingwe ndikuwonjezera nthawi yogwira ntchito yawo, gawo la chitetezo likhoza kuwonjezeredwa ku chivundikiro chakunja cha chingwe. Kawirikawiri pali mitundu iwiri ya chitetezo cha chingwe:tepi yachitsulozida zankhondo ndiwaya wachitsulozida zankhondo.

Kuti zingwe zizitha kupirira kupanikizika kwa radial, tepi yachitsulo iwiri yokhala ndi njira yolumikizira mipata imagwiritsidwa ntchito—iyi imadziwika kuti chingwe chotetezedwa ndi tepi yachitsulo. Pambuyo polumikiza zingwe, matepi achitsulo amazunguliridwa mozungulira pakati pa chingwe, kutsatiridwa ndi kutulutsa chidebe cha pulasitiki. Mitundu ya zingwe zomwe zimagwiritsa ntchito kapangidwe kameneka imaphatikizapo zingwe zowongolera monga KVV22, zingwe zamagetsi monga VV22, ndi zingwe zolumikizirana monga SYV22, ndi zina zotero. Manambala awiri achiarabu mumtundu wa chingwe akuwonetsa izi: "2" yoyamba ikuyimira zida zachitsulo ziwiri; "2" yachiwiri ikuyimira chidebe cha PVC (Polyvinyl Chloride). Ngati chidebe cha PE (Polyethylene) chikugwiritsidwa ntchito, nambala yachiwiri imasinthidwa kukhala "3". Zingwe zamtunduwu nthawi zambiri zimagwiritsidwa ntchito m'malo opanikizika kwambiri, monga malo owolokera misewu, malo otsetsereka, misewu yomwe imatha kugwedezeka kapena m'mbali mwa njanji, ndipo ndizoyenera kuyikidwa mwachindunji, ma tunnel, kapena kuyika ma conduit.

Kuti zingwe zithandize kupirira kupsinjika kwakukulu kwa axial, mawaya angapo achitsulo otsika mpweya amazunguliridwa mozungulira pakati pa chingwe—ichi chimadziwika kuti chingwe chotetezedwa ndi waya wachitsulo. Pambuyo polumikiza zingwe, mawaya achitsulo amakulungidwa ndi phula linalake ndipo chidebe chimatulutsidwa pamwamba pake. Mitundu ya zingwe zomwe zimagwiritsidwa ntchito pomanga izi zimaphatikizapo zingwe zowongolera monga KVV32, zingwe zamagetsi monga VV32, ndi zingwe za coaxial monga HOL33. Manambala awiri achiarabu mu chitsanzochi akuyimira: "3" yoyamba imasonyeza chitetezo cha waya wachitsulo; "2" yachiwiri imasonyeza chidebe cha PVC, ndipo "3" imasonyeza chidebe cha PE. Mtundu uwu wa zingwe umagwiritsidwa ntchito makamaka poyika nthawi yayitali kapena pomwe pali kutsika kwakukulu koyima.

Ntchito ya Zingwe Zokhala ndi Zida

Zingwe zotetezedwa ndi zida zankhondo zimatanthauza zingwe zomwe zimatetezedwa ndi chida chachitsulo choteteza zida zankhondo. Cholinga chowonjezera zida zankhondo sikuti kungowonjezera mphamvu yokoka ndi kupsinjika komanso kukulitsa kulimba kwa makina, komanso kukonza kukana kwa electromagnetic interference (EMI) kudzera mu chitetezo.

Zipangizo zodziwika bwino zotetezera zida zimaphatikizapo tepi yachitsulo, waya wachitsulo, tepi ya aluminiyamu, ndi chubu cha aluminiyamu. Pakati pa izi, tepi yachitsulo ndi waya wachitsulo zimakhala ndi mphamvu zambiri zolowera, zomwe zimapereka chitetezo chabwino cha maginito, makamaka chothandiza pakusokoneza ma frequency ochepa. Zipangizozi zimalola chingwe kubisika mwachindunji popanda ma paipi, zomwe zimapangitsa kuti zikhale njira yotsika mtengo komanso yogwiritsidwa ntchito kwambiri.

Chida choteteza chingagwiritsidwe ntchito pa chingwe chilichonse kuti chiwonjezere mphamvu ya makina komanso kukana dzimbiri, zomwe zimapangitsa kuti chikhale choyenera madera omwe makina angawonongeke kapena malo ovuta. Chikhoza kuyikidwa mwanjira iliyonse ndipo ndi choyenera kwambiri kuikidwa m'manda mwachindunji m'malo amiyala. Mwachidule, zingwe zoteteza ndi zingwe zamagetsi zomwe zimapangidwa kuti zigwiritsidwe ntchito m'manda kapena pansi pa nthaka. Pa zingwe zotumizira mphamvu, chida choteteza chimawonjezera mphamvu yokoka komanso yokakamiza, chimateteza chingwe ku mphamvu zakunja, komanso chimathandiza kupewa kuwonongeka kwa makoswe, kuteteza kutafuna kudzera mu chida choteteza chomwe chingasokoneze kutumiza mphamvu. Zingwe zoteteza zimafuna malo opindika kwambiri, ndipo chida choteteza chingathenso kukhazikika kuti chitetezeke.

ONE WORLD Imagwira Ntchito Zapamwamba Kwambiri Pakupanga Zipangizo Zapamwamba Zazingwe

Timapereka zida zonse zodzitetezera—kuphatikizapo tepi yachitsulo, waya wachitsulo, ndi tepi ya aluminiyamu—zomwe zimagwiritsidwa ntchito kwambiri mu fiber optic ndi zingwe zamagetsi kuti ziteteze kapangidwe kake komanso kuti zigwire bwino ntchito. Mothandizidwa ndi luso lambiri komanso njira yowongolera bwino kwambiri, ONE WORLD yadzipereka kupereka mayankho odalirika komanso okhazikika pazinthu zomwe zimathandiza kukonza kulimba ndi magwiridwe antchito azinthu zanu za chingwe.

Musazengereze kulankhulana nafe kuti mudziwe zambiri za malonda ndi chithandizo chaukadaulo.
