PCS building B551 is structurally connected to DNT/SAC production unit.The low voltage distribution system comprises transformer, low voltage switchgear, motor control center (MCC) and other related electrical equipments. 1.2 PCS楼内低压动力电缆采用交联聚乙烯绝缘聚乙烯护套型电缆沿桥架敷设。较大回路馈线采用单芯电缆成品字型排列敷设在地面上。控制电缆采用对绞屏蔽 DJYJPY型。动力电缆和控制电缆应敷设在不同的桥架内，若受限需同路径敷设时，中间应加隔板。Low voltage power cable will use cross-link PE insulation, PE out sheath copper cable running in cable ladder. For some big feeders, single-core cable shaped at tri-angle will be laid on the ground of PCS building. DJYJPY type will be chosen for instrument and control circuits. Power cable and control cable shall be laid in different trays. If space is limited and same routing is needed, separate plate shall be put inside the tray. 1.3 主要工程实物量一览表 Main material list 名 称 Item 规 格 Spec. 材质 Material 数量 Qty 电缆 cable YJY-0.6/1kV-1x400 mm2 YJY-0.6/1kV-1x300 mm2 YJY-0.6/1kV-3x185 mm2 YJY-0.6/1kV-3x185+2x95 mm2 YJY-0.6/1kV-3x120 mm2 YJY-0.6/1kV-3x95+2x50 mm2 YJY-0.6/1kV-3x70+PE35 mm2 YJY-0.6/1kV-4x50+PE25 mm2 YJY-0.6/1kV-4x35+PE16 mm2 YJY-0.6/1kV-4x10+PE10 mm2
