4 Core XLPE Wire 0.6/1KV YJV32 Copper 2.5mm 400mm Steel Tape Armoured Power Cable
4 Core xlpe wire
,1KV xlpe wire
,2.5mm armoured power cable
Xlpe Power Cable 0.6/1KV YJV32 Copper 4 Core 2.5mm 400mm Steel Tape Armoured Power Cable
| Model | YJV32 (steel tape armoured version) |
| Rated voltage | 0.6/1kV (U₀/U) |
| Conductor material | Annealed bare copper, class 2 stranded (GB/T 3956) |
| Number of cores | 4 cores (three phase + neutral; can also be 3+1 or equal section on request) |
| Conductor size range | 2.5mm² / 4mm² / 6mm² … up to 400mm² – any size available |
| Insulation | XLPE (cross-linked polyethylene) |
| Insulation thickness | According to GB/T 12706.1: e.g. 0.7mm for 2.5mm², 1.6mm for 400mm² |
| Armour | Double layer galvanized steel tape, helically applied (gap ≤45% of tape width) |
| Inner sheath | Extruded PVC (buffer between armour and insulation) |
| Outer sheath | Black flame-retardant PVC, oil & UV resistant (the “2” in YJV32 means PVC sheath) |
| Operating temperature | Normal: -15℃ to +90℃; Short circuit (max 5s): +250℃ |
| Min. bending radius | 15 × overall cable diameter (steel tape armour makes it stiffer) |
| Standard | GB/T 12706.1-2020 / IEC 60502-1 (CE report available) |
Typical Applications (real project examples)
-
Temporary construction power – steel tape armour resists stone crushing; even if outer sheath is scraped, the armour protects the insulation.
-
Wastewater treatment plants – wet environment + mild corrosive gases: PVC outer sheath + steel tape extends cable life by ~3 years compared to non-armoured.
-
Transformer LV side to distribution boxes – direct buried across roads, no need for extra conduits.
-
Solar farms – AC side from inverters to step-up transformers – 0.6/1kV rating fits perfectly.
Technical Data – Examples (small vs large sizes)
| Conductor size | Max DC resistance at 20℃ (Ω/km) | Air current rating (A, 30℃) | Approx. outer dia. (mm) | Approx. copper weight (kg/km) |
