Dab tsi yog qhov zoo ntawm BV Cable?
Jul 26, 2022
Bv hlau, feem ntau hu ua yas tawv hlau, nws lub npe tag nrho yog tooj liab tub ntxhais polyethylene insulated daim ntaub hlau. B txhais tau hais tias hom yog ntaub xov hlau, thiab V txhais tau tias lub rwb thaiv tsev txheej yog polyethylene. Nws yog qhov tsim nyog rau cov tshuab hluav taws xob nrog AC tam sim no ntawm 450/750v thiab qis dua, cov khoom siv hluav taws xob muaj zog txhua hnub, cov cuab yeej ntsuas thiab cov khoom sib txuas lus.
1, Kev faib tawm ntawm cov xov hlau BV
Bv xov hlau raug cais raws li lawv cov yam ntxwv: lawv muaj ob txoj haujlwm: nplaim taws retardancy thiab hluav taws kev nyab xeeb. Cov ntaub ntawv ntawm cov tsiaj ntawv Askiv yog zc-bv thiab n-bv raws, thiab daim ntawv thov teb yog raws li hauv qab no:
Zc-bv: tooj liab tub ntxhais high-voltage polyethylene insulated hlau: ib puag ncig tus phooj ywg nplaim retardant ntxiv rau cov khoom insulating, uas tsis yooj yim rau ntes hluav taws thaum tawm mus. nplaim retardant bv series khoom muab faib ua peb theem: A, B thiab C. ntawm lawv, chav kawm ib tug nplaim retardant theem yog zoo, thiab hais txog. Zc-bv feem ntau siv.
N-bv: tooj liab tub ntxhais high-voltage polyethylene cable sheathed ntxhia insulated cable: nws tuaj yeem siv tau raws li cov qauv hluav taws kub sib tsoo.
2, Qhov zoo ntawm BV hlau
BV yog ib qho tseem ceeb ib qho nyuaj hlau rau sab hauv kho kom zoo nkauj thiab teeb pom kev zoo. Ntxiv nrog rau kev siv nyiaj zoo, nws tseem muaj ob qhov zoo hauv qab no:
1. Nws muaj zog
Hauv kev kho kom zoo nkauj hauv tsev, lub zog sab nraud loj dua ntawm cov kab hluav taws xob tiv thaiv kom nruj thiab siab. Nyob rau hauv cov nqe lus ntawm tensile lub zog, ib tug tib tooj liab tub ntxhais hlau yog muaj zog - nyob rau hauv tag nrho cov txheej txheem ntawm kev kos duab thiab extrusion, cov tub ntxhais tooj liab hlau yog heev yooj yim mus ua txhaum, ua rau kom txo tau ntawm cable ampacity - ib tug nyias nyias tooj liab tub ntxhais hlau nrog ib txoj kab uas hla ntawm 0.41 hli
2. Cov hlau muaj peev xwm nqa tam sim no
Nyob rau hauv cov kab sib faib nrog luv-circuit txhaum, tsis tshua muaj zaus, tsis tshua muaj voltage thiab me me tam sim no (cov nyhuv ntawm daim tawv nqaij tsis suav hais tias yog), lub cable ampacity ntawm ib tug tooj liab tub ntxhais cable tshaj li ntawm ntau tooj liab tub ntxhais cable. PS: yog tias cov nyhuv ntawm daim tawv nqaij raug coj mus rau hauv tus account, lub cable ampacity ntawm ntau cov tub ntxhais kis tau tus mob yuav siab dua - qhov no kuj yog vim li cas vim li cas tsis muaj ib tug kis tau tus mob kab nyob rau hauv lub cable tshaj 10 hli.
