Panyaya yekubvumidzwa kwenguva refu-tembiricha yekuvhiringidza cores, ruzhinji rusimbiso runowanzoitika pa65 ° C, Polyvinyl Chloride Zvemapfupi-matunhu (neyakawandisa nguva isingapfuure mashanu masekondi), tembiricha yakanyanya kutenderwa ndeye 160 ° C yePVC insulation uye 250 ° C ye xlpe insulation.
I. Misiyano pakati peXLpe tambo uye PVC tambo
1. Low voltage kuyambuka-yakabatana (XLPE) tambo, kubva pakati pa1990 Sumo, ikozvino yazvidza kuti hafu yemusika pamwe nePolyvinyl chloride (PVC) tambo. Kuenzaniswa nePVC tambo, XLPE Cables inoratidza yakakwira zvazvino-kutakura kugona, uye yakanyanya kuwanda (PVC tarissi Kana ichipfuta, PVC inoburitsa utsi hweutsi dema uye magasi ane muchetura, nepo xlpe bunustion haaburitse ane muchetura ma gasi. Hukuru hwemuchinjiko-hwakabatanidzwa mabhokisi ari kuwedzera kuzivikanwa nekugadzirwa uye masangano ekushandisa.
2.. Ivo vanorasikirwa nesimba rekuchengetedza simba mukati me1 kusvika maviri maminitsi. PVC Kurovana kunoburitsa utsi dema dema, zvichitungamira pakufema matambudziko uye nekubuda matambudziko. Zvakanyanya kutsoropodza, pvc bunduisi inoburitsa masiketi ane chepfu uye hydrogen chloride (HCL) uye dicorins, iyo ndiyo inokonzeresa kufa kwemoto (accounting ye80% yevakafa nemoto. Aya magasi akaomeswa pamidziyo yemagetsi, kukanganisa zvakanyanya kuita kwekusimbisa kwekuita uye kutungamira kune vezera rezvese zvine njodzi kuderedza.
Ii. Murazvo-unodzoreredza tambo
1 Kirasi A inopa iyo yepamusoro-soro-inodzora kuita.
Kufananidza kwekutarisa bvunzo pamirango-inodzoreredza uye isina-murazvo-murazvo waya zvakaitwa neUS zviyero zveUS uye tekinoroji resealogy Institute. Mhedzisiro inotevera inoratidza kukosha kwekushandisa marimi-kudzoreredza tambo:
a. Murazvo-Wekudzoreredzwa waya inopa kanopfuura kagumi nemashanu nguva yekupukunyuka nguva ichienzaniswa nemurazvo wemurazvo-murazvo.
b. Murazvo-wekudzoreredza waya kupisa hafu chete hafu yezvinyorwa semurazvo-murazvo-waya waya.
c. Murazvo-Wetsoka wa waya inoratidzira kupisa kwekudziya kwehuremu chete chikamu cheiyo yemari isina-murazvo.
d. Tobe yethinzi yemasikati kubva mukusvibira inongova chetatu cheiyo yezvinhu zvisiri-zvekudzora-kudzoreredza zvigadzirwa.
e. Utsi hwechizvarwa hwekuita hunoratidza hapana mutsauko wakakosha pakati pemurazvo-kudzoreredza uye zvisiri-murazvo-kudzoreredza zvigadzirwa.
2. Halogen-isina vanhu-utsi tambo
Halogen-yemahara-yeutsi-hutachiona hunofanirwa kuve neHologen-mahara, svutugadzike-utsi, uye murazvo unodzora-kudzora hunhu, zvichitevera zvirevo:
IEC 60754 (Halogen-Free Test) IEC 61034 (Low-Utsi Test)
PH Heighted Underity Minimum Light Transmittance
Ph≥4.3 R≤10us / mm T≥60%
3. Moto-unodzivirira tambo
a. Moto-unodzivirira tambo yekuvhiringidzika bvunzo zviratidzo (tembiricha yemoto uye nguva) zvinoenderana IEC 331-1970 Standard ndeye 750 ° C kwemaawa matatu. Sekureva kweiyo yeChidimbu Iec 60331 nyowani nyowani kubva paIEC IEC kuvhota, iyo tembiricha yemoto inosvika 750 ° c kusvika 800 ° c kweawa matatu.
b. Mafaira emoto uye mabote anogona kuiswa mumurazvo wemoto-unodzora moto-unodzivisa tambo uye isina-murazvo-inodzorerwa moto tambo inoenderana nemisiyano yezvinhu zvisiri zve messallic. Domestic Fire-inodzivirira tambo shoma shandisa mica-coated contactes uye yakawedzera murazvo-kudzoreredza chimiro chavo chikuru, nekunyanya kuve yakanyanya class b zvigadzirwa. Avo vanosangana nekirasi zviyero zvinowanzo shandisa nzira dzakasarudzika michina uye mineral insultation
Matombo emaminerari ane moto-anopesana nemoto asingaoneki, isa utsi, ndezvekupokana, zvisina kujairika, zvinokanganisa simba, uye kuramba mvura yekupfira mvura. Ivo vanozivikanwa se tambo yemoto, vachiratidzira zvakanyanya kushamwaridzana kupisa kwemoto pakati pamoto-unodzivirira tambo marudzi. Nekudaro, maitiro avo ekugadzira akaoma, mutengo wavo wakakwira, kureba kwavo kwakapfuura, radius yavo yakakura, uye izvozvi, zvigadzirwa zveimwe chete zve25mms uye pamusoro zvinogona kupihwa. Nzvimbo dzisingaperi dzakazvitsaurira uye dzakabatana dzinobatanidza dzinodiwa, kugadzira kuisirwa uye kuvaka zvakanyanya kuomarara.
