YJV22 0.6/1kV Copper XLPE-Insulated Steel-Tape-Armored Power Cable
YJV22 adds a galvanized steel-tape armor layer to the YJV construction — the right choice when the cable will be direct buried, run through a cable trench with shared utilities, or installed where transverse mechanical impact is a real risk. PVC inner and outer jackets sandwich the armor for corrosion protection.

Overview
Construction order from conductor outward: Class 2 stranded copper, XLPE insulation, inner PVC bedding, two-tape galvanized steel armor with 50% overlap, PVC outer sheath. The armor adds transverse mechanical protection and a fault-current return path; the outer PVC prevents soil corrosion and abrasion during pull-in. Voltage rating, temperature limits, and bending radius mirror YJV — the only construction delta is the armor.
Key Features
Direct-buried ready
Armor + outer PVC qualifies the cable for direct burial under IEC 60502-1, no need for additional duct or pipe.
Mechanical impact tolerance
Two-tape steel armor protects against shovel and excavator strikes during routine excavation work.
PEN combined neutral / earth
Armor can serve as combined PEN return when bonded at both ends per TN-C wiring system rules.
Applications
Substation outdoor circuits
Buried cable runs from outdoor transformers to building service entrances and yard distribution boards.
Trench-shared utility routes
Shared cable trenches where mechanical impact from neighboring works is a recognized risk.
