YJLV22-0.6-1kV
YJLV22 Cable — Aluminium Conductor, Steel Tape Armoured XLPE Power Cable 0.6/1 kV
Aluminium conductors inside the same tape-armoured build: roughly half the drum weight of YJV22, for buried routes where the cable is the budget line.
YJLV22 is the point where the two cost levers combine. Substituting aluminium for the copper of YJV22 removes most of the conductor mass, while the double steel tape armour — unchanged in construction — keeps the mechanical protection needed for open-ground burial. On a long-distance feeder the combined effect is a materially lower price per metre and a drum that installs with fewer lifts and fewer joints along the route.
Keep two facts in view. First, aluminium needs the next standard size up to carry the same current, so the cross-section specified is larger than the copper equivalent even though the weight stays below it. Second, jointing discipline does not change because the cable is armoured: bimetallic lugs, joint compound and controlled torque are required at every termination. Voltcore issues the size mapping table with each quotation and can ship pre-crimped lugs cut and capped per drum.

Layer-by-layer construction
Listed from the conductor outward. Read this alongside the specification table — the two together tell you whether the cable will survive its installation method.
- 1. ConductorAluminium or alloy 8030 wires stranded to IEC 60228 Class 2 with a higher wire count per section than copper, then compacted
- 2. InsulationXLPE extruded over each conductor with the same thickness schedule applied to the copper range, colour coded or numbered for identification
- 3. Laying-up and fillerCores cabled with polypropylene filler and closed by a binder tape, keeping the profile round enough to seat the armour evenly
- 4. BeddingExtruded PVC inner covering separating the aluminium cores electrically and physically from the steel armour layer
- 5. Steel tape armourGalvanised steel tape applied in two counter-lapped layers with opposing lay direction to keep continuous coverage
- 6. OversheathBlack UV-stabilised PVC type ST1/ST2 extruded over the tapes to lock them down and resist abrasion in the trench

Engineering characteristics
- Combines the low material cost of aluminium conductor with full direct-burial protection at the standard armour thickness.
- Net weight around 45-55 % below the equivalent ampacity copper build, so long drum lengths reduce the number of joints per route.
- Alloy 8030 conductor above 61 % IACS resists the creep that caused loosening in older pure-aluminium installations.
- Identical radial crush performance to YJV22 because the armour layer is not changed when the conductor material changes.
- Extruded PVC bedding isolates the aluminium cores from the galvanised steel armour, avoiding direct metal contact at the interface.
- 90 °C continuous and 250 °C / 5 s short-circuit conductor ratings per IEC 60502-1, independent of conductor metal.
- Available with pre-crimped bimetallic lugs and torque specification sheets so site jointing follows one documented method.
Typical applications
- Long buried low-voltage feeders across industrial parks and campuses
- Perimeter and car park lighting distribution networks in open ground
- Rural electrification and peri-urban distribution for utility clients
- Solar park and wind farm array feeder runs requiring armour
- Temporary industrial camp supply lines laid directly in the ground
- Street lighting and pump house feeders where route length drives the budget
Ordering options
- Aluminium alloy 8030 or pure aluminium to IEC 60228 depending on regional practice

YJLV22 Aluminium Conductor Steel Tape Armoured Cable — frequently asked questions
How much weight do I save going from YJV22 to YJLV22?
For the same ampacity you move one or two sizes up in aluminium, and even then net weight falls roughly 45-55 %. As an example, 4-core 185 mm² YJV22 is about 10,200 kg/km while 4-core 185 mm² YJLV22 is about 5,050 kg/km, allowing far longer drum lengths per lift and fewer intermediate joints.
Does the steel armour react badly against aluminium conductors?
The two metals never touch. An extruded PVC bedding separates the laid-up cores from the armour, which removes any direct galvanic path. At terminations, Voltcore recommends tinned earth lugs and armour glands, plus antioxidant compound on the conductor barrels, so the aluminium and dissimilar metals are only joined through tested connector combinations.
Is YJLV22 allowed to be buried in the same way as YJV22?
Yes. The armour construction is unchanged, so the same trench detail applies: sand bed, screened backfill and marker tape. Note that aluminium is less tolerant of repeated flexing, so avoid re-bending a set cable and keep the minimum bending radius at 12 × overall diameter during installation.
What joints should I plan for on an aluminium armoured feeder?
Use deep-crimp bimetallic ferrules or friction-welded transition lugs with jointing compound, then torque to the connector value and recheck after six months. Armour continuity across straight joints needs a separate tinned copper earth braid. Voltcore supplies a compatible jointing kit list with every aluminium shipment.
