R - flexible cable (wire) for connection, flexible structure.

V - insulated PVC. V-pvc insulation v-pvc sheath

B-flat (flat).

S-twisted pair. A - tinned or silver plated.

F - high temperature resistance

P-braided shield p2-copper tape shield p22-steel tape armor

Y - prefabricated, generally omitted, or polyolefin sheath

FD - product category code, which refers to branch cable. The standards to be issued by the Ministry of construction are expressed in FZ, which are essentially the same

YJ - cross linked polyethylene insulation

V - PVC insulation or sheath

Zr - Flame Retardant

NH refractory

Wdz halogen free low smoke flame retardant

WDN - halogen free low smoke fire resistant type

For example: SYV 75-5-1 (a, B, c)

S: RF Y: polyethylene insulation V: PVC sheath a: 64 Series B: 96 Series C: 128 series

75:75 ohm 5: wire diameter is 5mm 1: represents single core

SYWV 75-5-1

S: RF Y: polyethylene insulation W: physical foaming V: PVC sheath

75:75 ohm 5: the outer diameter of the cable is 5mm 1: represents a single core

For example: rvvp2 * 32 / 0.2 rvv2 * 1.0 BVR

R: Flexible wire VV: Double sheathed wire P shielding

2: 2-core multi strand wire 32: each core has 32 copper wires 0.2: the diameter of each copper wire is 0.2mm

ZR-RVS2*24/0.12

Zr: flame retardant R: flexible cord s: twisted pair

2: 2-core multi strand wire 24: each core has 24 copper wires 0.12: the diameter of each copper wire is 0.12mm

Meaning of specification representation

The specification is expressed by the number of cores, nominal section and voltage level

① Specification representation of single core branch cable: number of cables in the same circuit * (1 * nominal section), 0.6/1kv,

For example: 4 * (1 * 185) + 1 * 95 0.6/1kv

② Specification representation of multi-core stranded branch cable: number of cables in the same circuit * nominal section, 0.6/1kv,

For example: 4 * * 185 + 1 * 95 0.6/1kv

③ Specification representation of multi-core same sheath branch cable: number of cable cores × Nominal section - t, e.g. 4 × 25-T

Complete model specification representation

Because branch cables include trunk cables and branch cables. Moreover, their specification structures are different, so there are two expression methods:

① Represent the trunk cable and branch cable respectively,

For example: 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 particularly concise in design and can easily show the different specifications of branch lines

② Show the trunk cable and branch cable together, such as fd-yjv-4 * (1 * 185 / 25) + 1 * 95 / 16 0.6/1kv

This method is intuitive, but * * * is limited to the case where the branch cable is of the same specification, and cannot represent different specifications of the branch:

Since the branch cable is mainly due to the 1kV low-voltage distribution system, its rated voltage of 0.6/1kv can be omitted in the design and marking.
