电力电缆用于输配电系统，本公司生产的交流额定电压0.6/1kV聚氯乙烯绝缘电力电缆和110kV及以下交联聚乙烯绝缘电力电缆，其性能不仅符合标准GB12706和IEC60502及IEC60840，并且已形成系列，即阻燃型的、耐火型的、耐寒型的和防水型的电力电缆。在阻燃型系列产品中，成功地应用了隔氧层技术，不仅0.6/1kV的聚氯乙烯绝缘和交联聚乙烯绝缘阻燃电力电缆能达到GB/T18380.3 《成束电线或电缆的燃烧试验方法》中A类，而且额定电压6/10kV及8.7/15kV交联聚乙烯阻燃电力电缆也能达到A类高阻燃要求且有较大裕度。在交联聚乙烯绝缘高阻燃的基础上又开发了低烟无卤高阻燃隔氧层电力电缆，其低烟无卤性能符合国家标准GB17651.1.2和GB/T17650.1.2。这样本公司的交联聚乙烯绝缘电力电缆的整体水平处于国内领先地位。 本公司生产的耐火型电力电缆为额定电压0.6/1kV铜芯电缆，还可以生产低烟无卤耐火电力电缆、高阻燃隔氧层耐用火电力电缆，其耐火性能符合GB/T19216-2003《在火焰条件下电缆或光缆的线路完整性试验》。因此，耐火系列电力电缆的整体性能优良可靠。 防水电缆的阻水性能符合IEC60502-2：1997规定。 本公司于2004年还开发了35kV及以下铝-镁-硅系高强度低电阻率非磁性铠装单芯电力电缆。该电缆突出的优点是： ① 高强度：铝-镁-硅合金丝具有较高的强度，其抗拉强度的最小值都是普通硬圆铝线（H8）抗拉强度的170%，是一种较好的铠装材料； ②损耗小：铝-镁-硅合金丝为非磁性材料，不存在涡流损耗；其在20℃时的电阻率相52.5~53.0%IACS（国际退火铜线标准），因此由感应电流产生的热损耗很小； ③重量轻：铝-镁-硅合金丝的密度仅为2.7g/cm3，明显降低了铠装电缆的整体重量。 由此可见，单芯铝-镁-硅合金丝铠装电缆完全可用于交流系统，并且不会降低导体的载流量。本产品完全可以替代进口产品。
Electric cable is adopted in transmission and distribution system of electricity. The XLPE cable with alternating-current rated voltage of 0.6/1kV and the cross-link XLPE cable of 110kV and below produced by us not only perform well up to the standards of GB12706, IEC60502 and IEC60840,but also have formed a series, ie. Cables of flame-retardant model, refractory model, frost-proof model and water-proof model.
The technique of oxide-blanket insulation has been successfully applied to the flame-retardant series. Not only have XLPE cable of 0.6/1kV and cross-link XLPE flame-retardant cable reached class A of GB/T18380.3 Test on bunched wires or cable, cross-link flame-retardant XLPE cable with rated voltage of 6/10kV and 8.7/15kV has also reached Class A highly flame -retardant qualification with a margin.On the basis of the cross-link flame-retardant XLPE series, we have developed the low-smoke non-halogen highly flame-retardant oxygen-tight electric cable, the low-smoke non-halogen degree of which conforms to the national standard of GB/T17651.1.2 and GB/T 17650.1.2. In general, the cross-link flame-retardant XLPE electric cable produced by us has been in the leading position domestically.
The refractory-model cable produced by our factory is the copper-cored cable with the rated voltage of 0.6/1kV, low-smoke non-halogen refractory cable and highly flame-retardant cable, the flame-retardant performance of which is in conformity to GB/T19216-2003 Integrity Test For Electric Cable Or Optic Cable Under The Flame Condition, so, generally the electric cable of refractory series performs well. The water-proof cable conforms to the standards of IEC60502-2:1977.
Our company developed aluminum-magnesium-silicon high strength, low resistance and non-magnetism armored power cable that with single core and of 35kV and 35kV below in 2004. The advantages of this cable are:
①High strength: Aluminum-magnesium-silicon alloy wire possesses high strength, its min value of tensile strength is 170% of the value of general hard and round aluminum wire(H8), is a fine armored material; ②Low loss:as a non-magnetism material, no eddy current loss will happened on aluminum-magnesium-silicon alloy wire; when under 20℃, itsunit resistance corresponding to 52.3~53.0%IACS (international annealed copper wire standard), so that, the heat loss caused by induced current is very low; ③Light weight: the density of aluminum-magnesium-silicon is only 2.7g/cm3 it largely reduced the total weight of armored cable. This shows that armored cable that with single core of aluminum-magnesium-silicon alloy wire is also suitable for AC system, and will not reduce the current carrying capacity of conductor.
This product can adequately replace the imported products. |
