style="text-indent:25px">常見的電纜故障：電線表面標志——根據(jù)國家標準規(guī)定，電線表面應有制造廠名、產(chǎn)品型號和額定電壓的連續(xù)標志。這有利于在電線使用過程中發(fā)生問題時能及時找到制造廠，消費者在選購電線時務必注意這一點。同時消費者在選購電線時應注意合格證上標明的制造廠名、產(chǎn)品型號、額定電壓與電線表面的印刷標志是否一致，防止冒牌產(chǎn)品。電線外觀——消費者在選購電線時應注意電線的外觀應光滑平整，絕緣和護套層無損壞，標志印字清晰，手模電線時無油膩感。從電線的橫截面看，電線的整個圓周上絕緣或護套的厚度應均勻，不應偏芯，絕緣或護套應有一定的厚度。中國電線電纜總產(chǎn)值已超過美國，成為世界上一大電線電纜生產(chǎn)國。</p><div
