Method of marking cables on drawings
Thread Content
This post was last edited by zhaohh3211 on 2010-12-14 at 14:33. I need to create a power layout diagram; almost all electrical equipment is located on level 0. I plan to bury all cables beneath the floor using conduit. From the distribution room to the electrical equipment, there should be two conduits: one for the power cables and another for the control cables used for wiring the control panels at the site. I would like to ask how these two types of cables should be labeled. For example, if my motor’s location code is PC3501, should the power cable be labeled as PC3501-EC, and the control cable as PC3501-CC? (I marked it according to the standards for instrument cables; I’m not sure how electrical components are labeled.) ）
Questions regarding design need to be answered by the friends from the design institute! Let me prop it up for you first!
As indicated by the labels: such as 3x25+1x10 and 7x1.5, others can tell at a glance that they are power cables and control cables.
The electrical diagram is drawn separately; other equipment and facilities are also shown on it, but they are all schematic illustrations. For the other equipment and facilities, only dimensions are provided without any other specifications; whereas for electrical equipment and materials, the relevant data and instructions are detailed and comprehensive. Pay close attention and observe.
It’s best to find some drawings (electrical construction drawings) for reference before drawing electrical diagrams on your own. If you can’t find it, you can look it up online. If you are in the city, you can go to a bookstore to check out electrical construction manuals. You can also contact friends who are designers at design institutes and have them send it to you online. Can I spend some money? It’s worth it.
No one replied: Power cable for electrical systems: EC; Control cable: CC.
Instrument: Signal cable: Instrument tag number C, e.g., FV-2113 C. Instrument power cable: Instrument tag number PC, e.g., FT-2113 PC. The cable specifications are indicated in the cable table; they are not shown in the diagram. Hope this helps!
