额定电压1kV(Um=1.2kV)到35kV(Um=40.5kV) 铝合金芯挤包绝缘电力电缆 第1部分：额定电压1kV (Um=1.2kV)和3kV (Um=3.6kV)电缆
Application Summary AI generated
This standard specifies the technical requirements, construction, dimensions, and test methods for aluminum alloy conductor power cables with extruded insulation, specifically for rated voltages of 1 kV and 3 kV. It is applied in low-voltage power distribution systems, industrial installations, and commercial buildings where aluminum alloy conductors are used as a lighter, cost-effective alternative to copper cables. The standard ensures cable performance for fixed installations such as in power grids, substations, and internal wiring of electrical equipment.
