Class 2 stranded copper conductor with a galvanized steel wire armour layer between PVC insulation and outer sheath, for underground feeds and industrial runs that need mechanical protection. Made on the Pilone line in Lahore.
Prices track the daily copper rate. Coil and bulk pricing on request.
| Property | Value |
|---|---|
| Conductor | Plain annealed copper, class 2 stranded circular |
| Nominal area | 35 mm² |
| Strand construction | 19 / 1.53 mm |
| Max conductor resistance at 20°C | 0.524 Ω/km |
| Current capacity, 2 loaded conductors | 138 A |
| Current capacity, 3 loaded conductors | 119 A |
| Voltage drop | 1.25 mV/A/m |
| Voltage rating | 600/1000 V (typical) |
| Insulation / sheath | PVC / PVC, 70°C conductor rating |
| Armour | Galvanized steel wire armour (SWA) between inner and outer PVC sheath |
| Conductor copper weight | ≈ 311.2 kg/km |
| Typical use | Distribution feeders and machine connections in industrial plants; larger underground feeds between buildings |
Voltage drop sets the longest run before lights dim and motors struggle. BS 7671 allows 3% on lighting circuits and 5% on other circuits; on a 230 V single-phase supply that is 6.9 V and 11.5 V. At this cable's 1.25 mV/A/m, the longest one-way run is:
| Load | Lighting circuit (3%) | Other circuits (5%) |
|---|---|---|
| 63 A | 87 m | 146 m |
| 80 A | 69 m | 115 m |
| 100 A | 55 m | 92 m |
| 125 A | 44 m | 73 m |
Check your own load and length with the voltage drop calculator. Every 100 m of each core holds 31.1 kg of copper; cable is priced from the day's copper rate, which is why each size up costs more.
Current capacity with two loaded conductors, BS 7671 reference method C, 30°C ambient. Same class 2 steel wire armoured construction in every size.
