VVGng-Ls waya uremu uye chokunze dhayamita

Popular VVGng-Ls waya nokuda wiring midziyo mumba, panze, Electrical chigadzirwa (migero, tunnels, zvikwepa, zviumbwe, etc.) Pasina tensile mutoro pamusoro chigadzirwa. midziyo dzino chinoshandiswawo apo kudiwa kwakawedzera moto vakachengeteka.

Ls VVGng kubva VVGng waya yakasiyana pakuti nechivako racho rinoshandisirwa voga, havakwanisi uori panguva secrete yakawanda dzoutsi.

Muzita waya Index Ls ndiye Low Utsi, iyo anoshandura se - "yakaderera-utsi" (kuputira uye bhachi vari akagadzirwa fireproof mapurasitiki, zvisina murazvo retardant).

kunyoresa

VVGng-Ls Cable rakagadzirirwa kushandiswa mune kuchitonhora, unozvidzora kana Tropical mumamirire ekunze. Izvi mhando waya zvinogona kushandiswa zvese panyika uye madziva, nzizi pagungano kukwira pamusoro pegungwa kusvika 4300 m.

Pachirehwa simba tambo:

• mumhepo kana pasina ngozi zvokuimba kukuvadzwa panguva oparesheni;
• rakaoma kana nyorova runyararo (reservoirs, tunnels, migero, maindasitiri kwakavakirwa, zvivako, vanotambura kukwana mafashamo, etc ...);
• muna kutigumbura, mabhiriji, inokosha waya Racks;
• In ngozi nzvimbo;
• nomoto zvivako;
• nokuti yokuvaka chiedza boka network iri ngozi munzvimbo.

Cable uremu VVGng-Ls inoita dzakakodzerana kutwasuka, chinjikira kana vachida makwara. Wire unarmored ichi mhando kunogona kushanda munzvimbo ine vibration.

Not pachii muchivande kugadzwa (panyika pemigero uye pasi) pasina kushandisa inokosha unodzivirira zvemagetsi (semuenzaniso, hoses kana nyere IPA) precluding kuvadza kondakita mumuhara uye ainawo oupenyu kwayo unongotaura.

Design zvinhu

• The conductors dzinoitwa nemhangura uye angava single- nezano kana, kuva raundi chimiro kana chikamu. GOST anopa I kana II kirasi kunzwisisa.
• Insulation rakagadzirwa polyvinylchloride epurasitiki wakati nani moto nemishonga uye vakaderera utsi womumwe. Mumwe insulated kondakita mu multicore netambo akagadzirwa PVC mavara akasiyana. Pachivanhu razero tambo vari yebhuruu, grounding - yeyero-uswa ruvara uye mavara pamwe nhamba "0".
• Inner waya mumuhara rinoshandisirwa pamusoro cores, richizadza voids therebetween uye nokusika kwokunze kuputira pakati chinoumba uye mamwe refractory unodzivirira rukoko.
• The dzokunze goko chakagadzirwa polyvinylchloride sezvamunoita uye ane yakawedzerwa moto nemishonga. Kana dhayamita pamusoro waya waya asingaiti kupfuudza 16 neMM, pakati chinoumba dzokunze bhachi nzvimbo achizadza bvumidzwa chinokosha refractory sezvamunoita. Panyaya iyi, kuti goko womukati hakuna kuzvireva.

Cable dhayamita VVGng-Ls

Mutsinga vakamonyanisa peya waya zvakafanana muchinjikwa-chikamu dhayamita. Kana nhamba cores 3-5, mumwe wavo ave madiki. Ichi pasi waya kana razero tambo.

The dhayamita uye kurema waya VVGng-Ls vari dzaona zvichienderana nokuwanda conductors marongerwo, magadzirirwo ayo zvinhu nevamwe.

Basic nokurondedzerwa

VVGng-Ls waya rinoshandiswa kuita uye kugadzwa magetsi kubva simba rokupa bhodhi uye transformer substations kuti simba zvirongwa: .. Production zvitoro, dzinogarwa uye okutarisira zvivako, rekuvaka, mabhizimisi upfumi uye voruzhinji utilities, etc. akabvumira kuripisa romugove waya dziri kongiri zviumbwe , tunnels, kutsigira piers.

waya rakagadzirirwa kupararira magetsi, izvo AC simba 0,66 KW kana zvachose - 1 KV.

The dzokunze goko yakaitwa kubva nezvinhu zvisina pachena kuti ultraviolet chiedza, nokuti chigadzirwa anogona yakachinjika muzuva. VVGng-Ls Cable kwete pachii kuisa mune kudzivirirwa kupikidura kuhondo.

• Bvumidzwa tembiricha uko waya inogona mazhinji kushandiswa - -50 ... +50 ° C
• Humidity anobvumirwa kusvika 98% (pa +35 ° C)
• cabling kuitwa panguva tembiricha haana kudzika pane -15 ° C
• Kushanda kudziyisa vaigara T - +70 ° C
• Kunonyanyisa zeva chimbichimbi oparesheni - +90 ° C (oparesheni asina kupfuura maawa 8 pazuva uye kwete kupfuura 1000 maawa yose webasa nguva)
• Nonincendive kuputira pa t +400 ° C
• Cable urefu, kondakita dhayamita, inova 1,5-16 neMM, ndiyo mamita 450; waya pamwe cores ane dhayamita pamusoro 25-70 mm - 300 M; kana kondakita dhayamita 95 mm uye zvakawanda - 200 m.
• Garandi webasa upenyu kubva nguva vachiisa kushanda - 5 makore kubva musi okuwana - kwete kupfuura 6 mwedzi.
• The upenyu basa kwemakore anosvika 30

yepamusoro kuzvidzora

Zvinotevera kuzvidzora nzira kuti tikwanise kuita rokutanga mhedziso pamusoro kunaka waya, kana tsika vakawana kubva yaidzorwa zvinosiyana yekudyidzana. Zvisinei, kwokupedzisira chitupa zvaidiwa GOST iyi inogona chete kuitwa pashure bvunzo nawo kushandiswa mumarabhoritari uye pasi zvachose nzira muhuwandu raanotaura mureza.

Visual rokuongorora uye nokuyerwa miganhu

Unogona nemaziso kutarisa uwandu coloring uye mutsinga, uwandu kondakita waya, kuvimbika Kamudzira uye kuputira, kuderedza vaparadzane.

With kuyera chishandiso anogona kutarisa pakukora ari goko uye yoga. Kuyerwa dhayamita pamusoro waya chikamu uye kukarukureta vakararama chaiyo payakavakirwa haisi kunyatsoteerera kudzora nzira, kureva. K. Kufananidza chikamu kunoratidza magetsi nemishonga. Kunyange zvakadaro, mumwe nouchapupu kutsauka (pamusoro 10%) dzaona kubva aizviti pamuchinjikwa-chikamu kungamutsa kupokana se.

Ichitenderera bvunzo pashure vakwegura panguva tembiricha yakaderera

Nzira iyi kana ndiro guru furiza ane tembiricha anosvika -15 ° C iri achiongorora yepamusoro wire mumuhara ane dhayamita wekunze 20 mm. Nokuti ichi akapeta kuti compactness ari rin'i wire chikamu (kureba anenge 1,2 m) akaiswa gwenya kwemaminitsi 45, uye ipapo akabvisa kwemaminitsi 5 kuti kuitisa ichitenderera dhiramu zvizere chimurenga. Drum dhayamita inofanira kuva 15 ∙ (Dn + d) ± 5%, apo Dn - chokunze dhayamita VVGng-Ls wire muna neMM, D - waya dhayamita mu mm. Panyaya iyi goko yepamusoro zvinofanira isina makatsemuka uye nemisodzi.
