Zokuvala - yayisoma eyodwa endincedayo ukukhusela uluntu iintambo obonakele, imibhobho, kunye nezinye izinto ezininzi, ngaphandle apho ubomi kunye nentuthuzelo wayo nje akunakwenzeka ukuba ngqondweni. Phambi kokuba wangena endlwini kubo bonke, amanzi, ubushushu, okanye umbane ukuhamba imigama emide, kunye nonxibelelwano rhoqo elise komhlaba, apho, ukongeza ubunzima ibekwe ibe ngaphezulu, kakubi iphenjelelwa ibingenakunyakama. Ngoko ke, lo bodwa - nto ikakhulu lokuzithethelela, namandla yayo ixhomekeke ayasiqinisekisa isakhiwo lonke.
Cable esingxobeni neentlobo zayo
I-inshorensi engaphandle nayiphi na iintambo maleko eziliqela, ezinako ukukulumkisela ukunika ukhuselo eliphezulu. Oku kunokuba laphu okhethekileyo, PVC, irabha, isinyithi kunye aluminiyamu zayo. Intambo yokwambathisa kuso wadlulisela uphawu sombane avotayo screen eyenziwe umnatha ngentsimbi, ngefoyile, film Polymer ogama umphezulu ibe nala ingxubevange yesinyithi. Polyvinyl chloride isetyenziswa ngokubanzi, esetyenziswa njenge usambathisa ethambileyo. Liquka kumafa zalo-50% kwezinto zeplastiki, ngenxa apho eziko umthamo izinto kunciphisa. Le nto ke igqunyiweyo iintambo amandla ombane aphezulu, ngokunjalo isikrweqe. Paper yokwambathisa ezisetyenziswa xa kusenziwa intambo kwaye yenziwa ukusuka unbleached sulphate yintlama. Polyethylene isetyenziswe umqhubi yokwambathisa apho aya kunikwa ezahlukeneyo parameters ukuya kilovolts ezingamakhulu amahlanu. Ezinye ezibhijeleyo indlela iintambo iipropati ezibalaseleyo ngoomatshini kunye nokukhuseleka yangoku. Material ixesha elide, ethembeke ukusebenza, kwaye kuzinzo thermal mkhulu zonke ezinye insulators.
Metal-yokwambathisa
Ukhetho ngcono ukudala uphawu nokuzabalazela ukufuma kucingwa metal, nezimo kunazo nobushushu-ukumelana yokukhokela gunya aluminium, ukuba zisetyenziswa kakhulu xa usambathisa umqhubi. Ububanzi iqokobhe ixhomekeke kwi sangqa intambo, kwakunye nemiqathango iza kusetyenziswa phantsi kwayo. Ekwenziweni yokugquma lead lisetyenziswa abakhokelayo-3 lophawu, apho metal olunyulu ubuncinane 95,95%. Ingongoma yokunyibilika ka 327,4 degrees Celsius, kodwa kunye onke amancedo amandla ngomatshini kwale nto esezantsi, kwaye flowability inyuswe, kodwa yinto ethile kakhulu ukuba ufakelo intambo nkqo equka oku imvulophu kuphela. umsebenzi eekhemikhali izinto iphantsi, nto leyo eya kuthi yongezwe yi ukumelana eliphezulu ukuya umhlwa. Le nto iye ukumelana ephantsi intlokoma, ingakumbi ngokubhekiselele lobushushu avuke. Ukuphucula uzinzo, ekwenziweni dopant kwistibhiya lifakiwe. Aluminium isetyenziselwa ukwenza intambo ka A-5, ukusulungeka ingxubevange yi 99,97%. mninzi but is eekhilogremu 2700 nge-cubic meter kunye uqine - 39,3-49,1 MPA. Loo iqokobhe yomelele amaxesha 2-2.5 ngokukhanya 4 amaxesha ngaphezu bakhokele. It iyamelana ukungcangcazela, kananjalo iimpawu uvikele. Kodwa apha umhlwa galvanic ngayo iyahlozinga, yaye ubugcisa bemveliso cable abasebenzi-kakhulu.
Hayi kuphela iqokobhe
Ukongeza iqokobhe, lo ezisongwayo - kukwayinto entle komqamelo, nezikrweqe kunye inshorensi yokhuselo, leyo likhusela ngokuchaseneyo umonakalo ukuba akanayo, ukumakishwa iqulathe ileta "T". Le pad senziwe material ezinezikhondo kunye itha, oko ukwakweli iqokobhe. Kukho ziyanyuswa uguqulelo ababetheki ziqulathe okukhona siya lamaphetshana ezimbini zeplastiki, ngenxa kuyo ngokunika ukhuselo ukusuka ngokudleka kunye lwangoku singawi. Le ntambo iqulethe ekuphawuleni ileta "L", iileya ezimbini tape alathelwe '2A'. Ukuba isicelo kwi ukusongwa polyethylene uphawulo iya kuba "P", yaye xa PVC - "B". Ukuba intambo asinayo mqamelo, eliphawulwe "B". Ububanzi komqamelo isusela ukusuka milimitha 1.5 ukuya 3.4.
Zempi ukukhusela intambo ngumonakalo ngomatshini, iya kwenziwa iziqwenga ezimbini nawo okusuka milimitha 0.3 ukuya 0.8, kodwa loo iintonga ezisetyenziswa xa kusenziwa imveliso leyo aya phantsi akhululeke. Ukuba ingxabano ukho, intambo sikhusela intsimbi kwalenza wire iflethi okanye angqukuva. Zenza zokwaleka wire caba ukusuka milimitha 1.5 ukuya 1.7, kwaye setyhula - ukusuka milimitha-4 ukuya ku-6. Ngaphandle babe kuqamba non-olunokutsha leyo yonyulwa "N", extruded zeplastiki ithumbu yokhuselo onombhalo - "DB", kunye PVC ithumbu ebizwa ngokuba "IIIB", iqala Ebubanzini ubuncinane milimitha 1.9 ukuya 3.
ngemibhobho
Ayibalulekanga kangako ke nangokomyinge intambo kunye umbhobho yokugquma, nto leyo ebanceda ixesha elide zikwazi ukwenza imisebenzi yazo. Adla ngokusetyenziswa ngendlela thermal, nto leyo uyalwa lokukhuselwa qhwa okanye ubushushu ukhuseleko enkulu. Zokuvala - eli lithuba nje sifudumele nokuthintela ngozi kwimeko yovalo, kodwa ukulondoloza imali. Ukhetho insulators omkhulu, njengokuba izinto ukusuka apho abewenzile, yonke kuxhomekeke tube kuyo.
iintlobo insulators
Mineral zoboya - yokwambathisa jikelele okuvumela sizikhusele ebandayo, ufudumale kwaye sineendlela iipropati nokubulala. Le izinto lingatshi liphele, kwaye asetyenziselwa abangelwe yayo ukwenziwa. Iwulu top ngefoyile ukuze kugalelwe okanye kwalenza. Kwakhona wasebenzisa polyethylene okanye polyethylene foamed, it has uhlobo ityhubhu okanye sheet. Le nto linamandla kakhulu ukuba ukufuma nokugcina ubushushu, oku kwakhokelela kwayo kwande. Eli candelo pipe unalo enobubanzi zeteknoloji kunye ngqo.
Yintoni enye ngerabha?
Kananjalo zingasetyenziswa zokwenziwa alephuze amagwebu irabha, nto leyo inokuba ngohlobo zombini tyhubhu neepleyiti. Kule ncwadi ibole kwaye akabi, yena, naye, ukufuma ayikho eyoyikekayo. paint thermal isicelo nayo enxulumene engamanzi bodwa, kufuneka kuphela umaleko encinane. kwamaqondo obushushu yokuyisebenzisa asusela thabatha kweqondo 60 dibanisa 200. Pipe, azigubungela ipeyinti, hayi kuphela akhuselwe, kodwa kumele i ukubukeka enomtsalane. Ukuze kutsalwe imathiriyeli ityhubhu, zifuna izincedisi kufuneke yokuncamathelisa, ezityiwa, iiteyiphu kwakuse kunye nezinye izinto. Phambi kokuba ekhusela nelembande, kuyimfuneko ukwenza imilinganiselo ngenyameko. Kude, njengokuba sisazi, kungenzeki kakhulu, kodwa ke umthamo omncinane oko kunokukhokelela yokonakala ngokukhawuleza.
