Cov hlau thaiv txheej yog ib qho tseem ceeb ntawm cov qauv hauvnruab nrab-voltage (3.6 / 6kV ∽ 26 / 35kV) cross-linked polyethylene-insulated fais fab cables. Kev tsim qauv ntawm cov ntaub thaiv hlau hlau kom raug, suav nrog qhov luv luv tam sim no cov ntaub thaiv npog yuav dais, thiab tsim cov txheej txheem kev tsim cov ntaub thaiv npog tsim nyog yog qhov tseem ceeb rau kev ua kom zoo ntawm cov kab txuas txuas txuas thiab kev nyab xeeb ntawm tag nrho cov kev ua haujlwm.
Txheej txheem shielding:
Cov txheej txheem tiv thaiv hauv nruab nrab-voltage cable ntau lawm yog qhov yooj yim. Txawm li cas los xij, yog tias tsis tau them nyiaj rau qee cov ntsiab lus, nws tuaj yeem ua rau muaj kev cuam tshuam loj rau cable zoo.
1. Daim kab xev tooj liabTxheej txheem shielding:
Daim kab xev tooj liab siv rau kev tiv thaiv yuav tsum yog tag nrho cov ntaub nplaum mos tooj liab uas tsis muaj qhov tsis xws luag xws li curled npoo los yog tawg ntawm ob sab.Daim kab xev tooj liabuas nyuaj dhau tuaj yeem ua rau puas tsuajsemiconductive txheej, thaum daim kab xev uas mos heev yuav wrinkle yooj yim. Thaum lub sij hawm wrapping, nws yog ib qho tseem ceeb uas yuav tsum tau teem lub wrapping lub kaum sab xis kom raug, tswj qhov nro kom zoo kom tsis txhob over-tightening. Thaum cov kab hluav taws xob muaj zog, rwb thaiv tsev ua kom sov thiab nthuav me ntsis. Yog hais tias daim kab xev tooj yog qhwv nruj heev, nws yuav embed rau hauv cov ntaub thaiv npog los yog ua rau daim kab xev tawg. Cov ntaub ntawv mos yuav tsum tau siv los ua padding ntawm ob sab ntawm lub tshuab shielding lub reel los tiv thaiv kev puas tsuaj rau daim kab xev tooj liab thaum cov kauj ruam tom ntej hauv cov txheej txheem. Copper daim kab xev yuav tsum yog qhov chaw-welded, tsis yog soldered, thiab yeej tsis txuas nrog plugs, nplaum tapes, los yog lwm yam uas tsis yog-standard txoj kev.
Nyob rau hauv cov ntaub ntawv ntawm tooj liab daim kab xev shielding, kev sib cuag nrog cov semiconductive txheej yuav ua rau oxide tsim vim qhov chaw tiv tauj, txo kev sib cuag thiab ob npaug tiv thaiv tiv thaiv thaum cov hlau shielding txheej undergoes thermal expansion los yog contraction thiab dabtsi yog khoov. Kev sib cuag tsis zoo thiab thermal expansion yuav ua rau muaj kev puas tsuaj rau sab nraudsemiconductive txheej. Kev sib cuag zoo ntawm daim kab xev tooj liab thiab cov txheej txheem semiconductive yog qhov tseem ceeb los xyuas kom muaj kev sib raug zoo hauv av. Overheating, raws li qhov tshwm sim ntawm thermal expansion, tuaj yeem ua rau daim kab xev tooj liab nthuav dav thiab deform, ua rau cov txheej txheem semiconductive puas. Nyob rau hauv tas li ntawd, cov kev sib txuas tsis zoo los yog tsis zoo welded tooj liab daim kab xev tuaj yeem nqa ib qho kev them nqi tam sim no los ntawm qhov tsis muaj av kawg mus rau qhov kawg hauv av, ua rau overheating thiab sai aging ntawm cov txheej semiconductive ntawm qhov chaw ntawm daim kab xev tooj liab tawg.
2. Copper Wire Shielding txheej txheem:
Thaum ua haujlwm xoob cov tshuab luam ntawv xov tooj liab, cov xaim tooj liab ncaj qha, muaj peev xwm ua kom lub rwb thaiv kom nruj, ua rau muaj kev puas tsuaj cable. Txhawm rau hais qhov no, nws yuav tsum tau ntxiv 1-2 txheej ntawm semiconductive nylon daim kab xev nyob ib ncig ntawm lub extruded semiconductive sab nrauv ntaub thaiv npog tom qab extrusion.
Cables siv xoob xoob tooj liab hlau thaiv kev tiv thaiv tsis raug kev txom nyem los ntawm oxide tsim nyob nruab nrab ntawm cov kab xev tooj liab. Copper wire shielding muaj tsawg kawg yog khoov, me ntsis thermal expansion deformation, thiab ib tug me me nce nyob rau hauv kev sib cuag tiv thaiv, tag nrho cov no pab txhawb kev txhim kho hluav taws xob, mechanical, thiab thermal ua hauj lwm nyob rau hauv cable.
