"B"                      Bronze armor
"T"                      Tinned copper armor
"_S"                    Armor and sheath (3)
"CWCMC"         Continuously corrugated metal armor

(3) = Add the type of armor, A, B, or T, before the S.


D.5.19.1.6 Size
The wire size is designated for distribution cable by adding a dash (-), followed by the conductor
size in kcmil.


D.5.19.1.7 Voltage rating


The rated distribution cable voltage is added to the symbol following a dash (-), as follows:
2 000 V                          2 kV
5 000 V                          5 kV
8 000 V                          8 kV
15 000 V                        15 kV
25 000 V                        25 kV
28 000 V                        28 kV
35 000 V                        35 kV

The complete type designation should include the following parts:
—    Cable type (S, D, T, F, Q, C, TP, TT)
—    Shielding designation, if applicable
—    Insulation type
—    Jacket type
—    Armor, if applicable
—    "S" if jacket over armor

For Types S, D, T, F, and Q, distribution cables.
Following a dash (-), the conductor size in kcmil is as follows:

—    DTTB-4  =  AWG  14  (4.11  kcmil),  two-conductor,  polyvinylchloride-insulated, 
thermoplastic
polyvinyl chloride jacketed, and bronze armored
—    SXNA-250  =  250  kcmil,  single  conductor,  cross-linked  polyethylene  insulated, 
Thermoset neoprene jacketed, and aluminum armor
—    TPNBS-313 = 3 conductor, 313 kcmil, polyolefin insulation with neoprene jacket, bronze armor,
and overall sheath

Following a second dash (-), the voltage rating is as follows:
—    TPNBS-313-5KV = 3 conductors, 313 kcmil, polyolefin insulation with neoprene jacket, bronze
armor, and overall sheath, 5 kV.

For Types C, TP, and TT, the number of conductors, pairs or triads, as applicable; the number  of
conductors of control, and the number of conductor pairs/triads of signal cable, is added to the
cable designation, as follows:
—    C14TCPB-20  =  20  conductor  control  cable,  14  AWG,  thermoplastic-insulated,  Thermoset
chlorosulfonated polyethylene jacketed, and bronze armor
—    TP18TNA-10  =  10  twisted  pair  signal  cable,  18  AWG,  thermoplastic-insulated, 
Thermoset neoprene jacketed, and aluminum armor
—    C14PCP-3  =  3  conductor,  14  AWG,  polyolefin  insulated,  and  chlorosulfonated 
polyethylene jacketed
—    TP (OS) 18PNBS-2 = 2 twisted pairs, 18 AWG with polyolefin insulation, overall tape shield and
drain wire, neoprene jacketed, with bronze armor and overall outer sheath
