　　產(chǎn)品特色

　　FEATURES

　　本產(chǎn)品除具有普通聚氯乙烯絕緣電力電纜、低壓交聯(lián)電力電纜的特性外，還有以下特點(diǎn):

　　(1)具有較低且均勻的正(逆)序和零序阻抗，有利于改善供電品質(zhì)。

　　(2)同心層導(dǎo)體比普通四芯電纜的第四芯在零序工作狀態(tài)下的電抗值低得多,有利于短路自動(dòng)保護(hù)裝置的靈敏動(dòng)作，從而保證電纜和相關(guān)設(shè)備的安全運(yùn)行。

　　(3)具有較強(qiáng)的抗電磁干擾性能和抗雷擊性能。

　　(4)五芯電纜適用于TN-S和TN-C-S系統(tǒng)的供電。

　　Besides the properties of common PVC insulated power cable ,it has the following advantages;

　　1.it has lower and regular positive (inverted)sequence andzero sequence impedance ,Benefit to the ameliorative powersupply quality.

　　2.copared with the fourth core of common 4-core cable ,thereactance value of concentric conductor is much lower underthe working condition of zero sequence, which improves thesensitive action of short-circuit auto-protection device andensure cable and relative equipments safe operation.

　　3.it has strong properties of anti-electromagnetic interfere-nce and anti-thunderstrike.

　　4.five-core cable is suitable for power supply of TN-S and TN-c-S system.
