The meaning of the specification notation:
Specifications using the number of cores, nominal cross-section and voltage levels indicate:
1 Single-core branch cable specification notation: number of cables in the same loop*(1*nominal section), 0.6/1kV,
For example: 4*(1*185)+1*950.6/1kV
2 Multi-core stranded branch cable specification notation: number of identical loop cables* nominal cross section, 0.6/1kV,
For example: 4**185+1*950.6/1kV
3 Multi-core and sheathed branch cable specification notation: number of cable cores × nominal cross-T, such as: 4 × 25-T
Complete model specification notation:
Because the branch cable contains the trunk cable and the branch cable. And the two specifications are different, so there are two ways to represent:
1 The trunk cable and the branch cable are respectively represented, such as: trunk cable: FD-YJV-4*(1*185)+1*950.6/1kV
Branch cable: FD-YJV-4*(1*25)+1*160.6/1kV
This method is particularly concise at the time of design and can easily show the difference in branch line specifications. 2 The trunk cable and the branch cable are shown together, such as: FD-YJV-4*(1*185/25)+1*95/160.6/ 1kV
This method is more intuitive, but it is limited to the case where the branch cable is of the same type, and it cannot represent different specifications of the branch line: Since the branch cable is mainly due to the low voltage distribution system of 1kV, the rated voltage of 0.6/1kV can be specified in the design callout. Omitted.
