Control and instrument cable is specified by structure rather than by size, and the first question is whether the conductors are arranged as cores or as pairs. Cores are for switching and interlocks; twisted pairs are for signals, because the twist is what makes the pair reject the interference a variable speed drive throws into a cable tray. The second question is screening, and it has three answers that are not interchangeable: an overall screen protects the bundle from outside noise, individual pair screens stop the pairs interfering with each other, and both together are what an analyser or a thermocouple run usually needs. Two practical points close the enquiry. Spare cores are cheap at order time and expensive later, so most sites specify a percentage. And core identification — numbered, coloured or both — should match the site drawing convention, since a marshalling cabinet wired against the wrong convention costs days.
The more of this you send, the closer the first quotation lands.
| Structure | Multicore, twisted pairs, or triples |
|---|---|
| Core or pair count | Working count plus the spare percentage required |
| Conductor size | Typically 0.5 to 2.5 square millimetres |
| Screening | Overall screen, individual screens, or both |
| Drain wire | Required for terminating the screen at one end |
| Core identification | Numbered, colour coded, or to a named site convention |
| Signal type | Digital contacts, 4-20 mA, thermocouple or RTD |
| Insulation and sheath | XLPE or PVC insulation, PVC or LSZH outer sheath |
| Armour | State if the route needs steel wire armour or braid |
| Route environment | Tray shared with power cables, buried duct, or in a rack |
| Fire performance | Flame propagation, halogen-free, or circuit integrity if required |
| Drum lengths | Continuous lengths per run, and the total quantity |
