Armoured communication cable armoring cable type: HYA53, HYAT53, HYA23 HYAT23, HYV22, HYA22 (rat, buried) armoring communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and designed and vulnerable to erosion area telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter. 5. The marking contents of armored communication cables include: wire diameter, number of wire pairs, cable model, length, manufacturer name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical requirements of the basic cable. 6. Cable length: mechanically protected cable is made according to the length of the corresponding basic cable

该条件均适用于U0和U值。
当用于直流系统时,该系统的标称电压应不大于电缆额定电压的1.5倍。
注:系统的工作电压允许长时间地超过该系统标称电压的10%。
如果电缆的额定电压至少等于该系统的标称电压,则电缆可在高于额定电压10%的工作电压下使用。
一般情况下,在三相四线制线路中,零线截面要大于相线截面的50%。
合理选取零线截面是由于这类线路的负荷构成中,单相负载占有很大比重,用电时间上也有差异,各相负荷处于不平衡状态,零线上经常会有电流流过,如果零线选择不当,就容易发生烧断零线事故而造成大面积烧坏电气设备事故。
接至用电设备的保护零线应有足够的机械强度,应尽量按IEC标准选择零线的截面和材质,架空敷设的保护零线应选用截面不小于10mm2的铜芯线,穿管敷设的保护零线应选用截面不小于4mm2的铜芯线。

BCD码的低3位各位只能是0~9,如果是16#A~16#F则会出错。
计数器的预设值PV是0~999的BCD码,可以用格式为C#的常数(C#1~C#999)作为计数器的预设值。
下图用MW42提供计数器的预设值PV,如果用MOVE指令将十进制数348(对应的十六进制数为16#15C)传送给MW42,进入RUN模式时,操作系统将它转换为BCD码时出错(16#15C不是BCD码),不能切换到RUN模式。
输入预设值348时,应改为将C#348传送给MW42,它会自动地变为W#16#348,当然也可以直接输入16#348。
