产品特色
FEATURES
本产品除具有普通聚氯乙烯绝缘电力电缆、低压交联电力电缆的特性外，还有以下特点:
(1)具有较低且均匀的正(逆)序和零序阻抗，有利于改善供电品质。
(2)同心层导体比普通四芯电缆的第四芯在零序工作状态下的电抗值低得多,有利于短路自动保护装置的灵敏动作，从而保证电缆和相关设备的安全运行。
(3)具有较强的抗电磁干扰性能和抗雷击性能。
(4)五芯电缆适用于TN-S和TN-C-S系统的供电。
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.
