Voltage: 0.6/1kV (Um=1.2kV), test 4kV
Conductor: Aluminium, Class 1 or 2, IEC 60228
Insulation: XLPE, rated 90°C, 250°C short-circuit
Armour: Double galvanized steel tape (non-magnetic for 1-Core)
Sheath: Black PVC, flame retardant, IEC 60332-1
Temperature: -35°C to +90°C (fixed), +5°C to +90°C (flexed)

Product Overview

YJLV22 Cable is a 0.6/1kV XLPE-insulated steel tape armoured PVC-sheathed power cable with aluminium conductor, manufactured to the Chinese national standard GB/T 12706.1 and international standard IEC 60502-1. Naming follows GB/T convention: YJ = XLPE insulation (cross-linked polyethylene), L = aluminium conductor, V = PVC sheath, 22 = double steel tape armour. It is structurally identical to the VDE-designated NA2XBY — both are Al/XLPE/STA/PVC 0.6/1kV armoured cables differing only in the certifying standard (GB/T vs VDE). YJLV22 is the aluminium counterpart of the copper YJV22, offering significant weight reduction and lower material cost. Single-core variants use non-magnetic (aluminium) tape armour to prevent eddy current losses in AC circuits.

YJLV22 Cable Cross Section with 3D Cutaway and 2D Cross-Section

Outer Sheath — Black PVC, flame retardant
Steel Tape Armour — Double galvanized, helically applied
PVC Bedding — Light blue-grey extruded separation sheath
XLPE Insulation — 90°C, GB/T 12706.1 colour coded
Aluminium Conductor — Class 2 stranded per IEC 60228

Aluminium Conductor

Class 1 (solid) or Class 2 (stranded) per IEC 60228. Solid for ≤4mm². 61% IACS at ~50% weight of equivalent copper.

XLPE Insulation

90°C continuous, 250°C short-circuit (max 5s). Test voltage 4kV. GB/T 12706.1 colour coded per HD 308 S2.

PVC Bedding

Light blue-grey extruded separation sheath between cores and armour. Prevents XLPE abrasion from steel tape edges during bending.

Steel Tape Armour

Double galvanized steel tape. Non-magnetic (aluminium) tape for single-core to prevent eddy currents. 0.2mm for ≤35mm², 0.5mm for ≥50mm².

PVC Outer Sheath

Black PVC, flame retardant per IEC 60332-1. UV resistant for outdoor installation. Moisture-proof for underground use.

GB/T Certified

Chinese national standard GB/T 12706.1. Structurally identical to NA2XBY (VDE) — same Al/XLPE/STA/PVC, different certification.

Applicable Standards

Standard	Scope
GB/T 12706.1	Chinese national standard for extruded insulation power cables rated 1kV (Um=1.2kV) to 3kV (Um=3.6kV). Primary standard covering YJLV22 construction, testing, and type designation.
IEC 60502-1	International standard for LV extruded insulation power cables. YJLV22 meets all IEC 60502-1 structural and electrical requirements. Equivalent VDE designation: NA2XBY.
IEC 60228	Conductor standard. Class 1 solid and Class 2 stranded aluminium conductors.
IEC 60332-1	Single cable vertical flame test. Mandatory for building installation cables.
HD 308 S2	Harmonised European core identification standard. Widely adopted by Chinese manufacturers for export-grade cables.

GB/T Naming Convention

Letter	Meaning	Description
YJ	XLPE insulation	Cross-linked polyethylene, 90°C rated
L	Aluminium	Aluminium conductor (omit for copper: YJV22)
V	PVC sheath	Polyvinyl chloride outer sheath
22	Steel tape armour	Double galvanized steel tape (23 = steel wire, 32 = steel wire heavy)

YJLV22 vs NA2XBY vs YJV22: YJLV22 (GB/T) and NA2XBY (VDE) are structurally identical — Al/XLPE/STA/PVC 0.6/1kV — differing only in the certifying standard. YJLV22 removes the "L" for copper: YJV22 = Cu/XLPE/STA/PVC (equivalent to N2XBY). The "22" digit is the GB/T armour code: 22 = steel tape, 23 = steel wire, 32 = steel wire armour heavy. For single-core AC, non-magnetic (aluminium) tape is mandatory to prevent eddy current heating — this is designated by the same "22" code but with aluminium tape material.

Technical Specifications

Typical Applications

Underground Distribution

Direct burial in soil for LV power networks. Steel tape armour provides mechanical protection; XLPE insulation ensures reliable long-term underground performance.

Industrial Feeders

Power supply to high-load motors, transformers, and production lines. 90°C XLPE handles overload conditions reliably.

Building Main Supply

Main distribution cables in commercial and residential buildings. 12×D bending radius for multi-core routing through conduits and cable trays.

Solar & Wind Farms

LV collector circuits in renewable energy projects. Aluminium conductor economics favour long cable runs.

Cable Trenches & Trays

Open-air installation on cable trays or covered trenches. UV-resistant black PVC sheath for outdoor routing.

Infrastructure Projects

Water treatment, pumping stations, tunnel lighting, and transport infrastructure requiring GB/T-certified armoured cable.

YJLV22 vs YJV22 — aluminium vs copper: YJLV22 uses aluminium conductor with the same XLPE/STA/PVC construction as YJV22 (copper). Aluminium DC resistance is ~1.68× copper at the same cross-section (IEC 60228). For export projects, YJLV22 is structurally equivalent to NA2XBY (VDE/IEC). For maximum conductivity, specify YJV22 (copper). For projects where aluminium economics are acceptable, YJLV22 delivers GB/T-certified XLPE armoured performance at substantially lower material cost.
