Tsananguro General uye anokosha akasiyana-siyana VVG Wire

The waya (wire) VVG ine conductors, zvakagadzirwa nemhangura uye zvinenge zvakazara paiva PVC. It ane sandara chimiro uye kazhinji kacho rinoshandiswa kuparadzira yemagetsi simba pamwe unozotevera kuparadzira raro siyana mira michina. Dzinonzi yavose sezvavakatarirwa tambo iyi nokuda voltage anosvika mumwe kilowatt. Vamwe pezvitsiga vari kushanda panguva dzakakwirira prices. waya Izvi zvinogona vakaradzikwa rakaoma ezvinhu, uye avo vari pedyo kumusoro mwando inozivikanwa. Kazhinji waya VVG anogona kuwanikwa chaidzo mumabhokisi waya, ramps uye kunyange panze. Zvinofanira kucherechedzwa kuti vave kuisa chinjikira, vachida uye kutwasuka makwara, uye munzvimbo dziri pedyo dzakakwirira kwevari vibration inozivikanwa. Nzvimbo chete apo hazvina chinodiwa kuti ndikaisa waya - zviri pasi pevhu. Huru uye inonyanya waya VVG inorondedzerwa pazasi.

Mumwe Musimboti zvikukutu uye ane tenderera chimiro. Its chezita muchinjikwa-chinogona kuva kusvika 16 mativi millimeters. PVC mapurasitiki rinoshandiswa nokuda kwezvifananidzo zvaAtemisi kuputira. Zvinofanira kucherechedzwa kuti mumuhara mumwe conductors ane zvakasiyana coloring. External bhora kuzivikanwa kwayo pasi flammability, uye kazhinji kacho ane chena ruvara. The gasket inokurudzirwa panguva tembiricha kubvira 15 kusvika 35 Celsius uye mwando 98%. simba iri waya uyewo ayo mamwe mavanga, ane furati chakagadzirwa. Features waya VVG-P kumar kubvumira kuzvishandisa panguva kumbonyanya yakakwirira dziine epfungwa.

mhando iyi zvakasiyana, pasi flammability, uye yeEncoding Ls (Low Utsi) kunoratidza kuti chigadzirwa ane pasi azvipire gasi achine uye utsi. Sezvo hazvina murazvo retardant, izvozvo anowanzodanwa rakashandiswa kugoverwa yemagetsi simba iri waya vanosvuta, zvivako uye zvivako apo AC yavose sezvavakatarirwa voltage kubva 660 V kusvika 1000 V pa 50 Hz.

The nemamiriro mutsinga

In waya VVG-P Ls kumar waya, electrically conductive, akaita nemhangura uye angava chimwe-waya kana multiwire. Kana stranding cores maviri kana matatu, ipapo ivo vose zvakafanana muchinjikwa-chikamu, uye kana mana - ipapo wokupedzisira, zviri zviduku. Rinoshandiswa kuti grounding uye anonzi razero. In anogadzira zvinhu kuputira akashandisa chaiyo PVC sezvamunoita kuti kunoratidzwa yakakwirira kuramba combustion. The goko nechimwe makirisito ane zvakasiyana ruvara, muchiitiko ichi razero anogara mutema. Pakukora yomukati rukoko haidereri pane millimeters matatu. Zvinofanira kucherechedzwa kuti zvikamu pakati conductors uye kuputira azara PVC nziyo hwokurara kwazviri.
