Overhead Power Lines

Cov kab hluav taws xob siv hluav taws xob tau siv dav hauv cov kab hluav taws xob sab nraum zoov. Lawv haum rau siab -, nruab nrab -, thiab qis -voltage kab. Qhov luaj li cas yog los ntawm 10 mus rau 800 square mm, thiab tus ntoo khaub lig zoo -sectional cheeb tsam sib phim qhov no. Cov stranding muaj 7, 19, 37, lossis 61 xov hlau. Cov khoom no feem ntau yog siv rau hauv cov phiaj xwm hauv nroog, cov chaw xa khoom nyob deb nroog, thaj chaw muaj kev lag luam, thiab cov chaw ua haujlwm substation. Lawv haum rau yuav luag txhua qhov kev thov ib puag ncig.

Lub cable tiv taus cua sov, txias, tshav ntuj, cua vibration, thiab dej khov. Aluminium ib txwm tsim cov txheej txheem oxide tiv thaiv uas tiv thaiv corrosion. Lub zuag qhia tag nrho qhov hnyav yog qhov tsawg, txo cov load ntawm ncej. Nws ua tau zoo nyob rau hauv ntev - nrug thiab loj - ncua kev teeb tsa. Tus nqi tsis ua haujlwm yog tsawg, thiab cov nqi kho mob tsawg tsawg. Cov kab hluav taws xob tuaj yeem ua haujlwm nyab xeeb txog li nees nkaum-tsib xyoo nyob rau hauv huab cua hnyav. Cov kab hluav taws xob overhead no tseem yog siv dav tshaj plaws thiab raug nqi - kev xaiv zoo rau kev xa hluav taws xob.
