Lub hauv paus qauv ntawm lub hwj chim cable muaj plaub yam: core (conductor), rwb thaiv tsev txheej, shielding txheej thiab tiv thaiv txheej.
Core
Cov tub ntxhais yog cov khoom siv hluav taws xob ntawm lub zog hluav taws xob, siv los xa hluav taws xob hluav taws xob, thiab yog qhov tseem ceeb ntawm lub hwj chim cable.
Rwb thaiv tsev txheej
Cov txheej txheem rwb thaiv tsev yog txhawm rau cais cov tub ntxhais ntawm lub ntiaj teb thiab cov cores ntawm cov theem sib txawv ntawm ib leeg kom ntseeg tau tias kev sib kis ntawm hluav taws xob. Nws yog ib feem tseem ceeb ntawm lub zog cable qauv.
Shielding txheej
Fais fab cables ntawm 15kV thiab saum toj no feem ntau muaj cov neeg xyuas pib shielding txheej thiab rwb thaiv tsev thaiv txheej.
Kev tiv thaiv txheej
Lub luag haujlwm ntawm cov txheej txheem tiv thaiv yog los tiv thaiv lub hwj chim cable los ntawm kev nkag mus rau sab nraud impurities thiab noo noo, thiab tiv thaiv sab nraud quab yuam los ntawm kev puas tsuaj rau lub hwj chim cable.
