The meaning of the specification notation
Specifications are expressed in number of cores, nominal cross-section and voltage level
1 Single-core branch cable specification: The number of cables in the same loop*(1*nominal section), 0.6/1KV, eg: 4*(1*185)+1*95 0.6/1KV
2 Multi-core stranded branch cable specification notation: the number of the same loop cable * nominal cross section, 0.6/1KV, eg: 4**185+1*95 0.6/1KV
3 Multi-core and sheathed branch cable specification notation: number of cable cores × nominal cross-T, such as: 4 × 25-T
Complete model specification representation
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 main cable and the branch cable are separately represented,
Such as: trunk cable: FD-YJV-4*(1*185)+1*95 0.6/1KV
Branch cable: FD-YJV-4*(1*25)+1*16 0.6/1KV
This method is especially concise at design time and can easily show the difference in feeder specifications.
2 Together with the trunk cable and branch cable, such as: FD-YJV-4*(1*185/25) +1*95/16 0.6/1KV
This method is more intuitive, but it is limited to the situation where the branch cable is of the same type, and it cannot represent the different specifications of the branch line:
Because the branch cable is mainly due to the 1KV low voltage distribution system, its rated voltage of 0.6/1KV can be omitted when designing the label.
