Low-smoke halogen free power cable single core cable conductor is round, 16mm2 and above can be pressed tightly. If the cross section of multi-core cable core is 35mm2 or below, its core should be round, and the cross section of wire core should be fan-shaped, tile or semi-circular at 50mm2 and above. The fourth core (neutral core) of a four-core cable can be round or fan shaped. The neutral line of five-core cable can be round or tile type 6mm2 or below. It is allowed to be composed of a single conductor. Forming conductors (fan-shaped, tile or semi-circular) shall be pressed tightly.

实际使用时，调整端ADJ采用悬浮式，即通过外接的取样分压电阻R1和R2来设定输出电压。输出电压大小可用公式Uo=1.25（1+R2/R1来计算。显然，如果将调整端ADJ直接接地，则输出端Uo会输出稳定的1.25V电压。注：上图所示是正电压输出三端集成稳压器的内部电路框图。对于相应的负电压输出三端集成稳压器，其内部结构和工作原理与正电压输出三端集成稳压器基本相同，所不同的是调整管被接成了集电极输出型。

为便于安装、运行和维护，在二次回路中所有设备间的连线都要进行编号，称为二次回路标号。标号一般采用数字或数字和文字的组合，它表明了回路的性质和用途。二次回路标号的基本原则：凡是各设备间要用控制电缆经端子排进行连接的连接导线，都要按回路编号原则进行编号。某些装在屏顶上的设备与屏内设备的连接也需经过端子排，此时屏顶设备就可看作是屏外设备，而在其连接线上同样要按回路编号原则给予相应的编号。为明确起见，对直流回路和交流回路采用不同的标号方法，而在交、直流回路中，对各种不同的回路又赋予不同的数字符号。
