Must-have for Underground Laying! A Complete Guide to YJV22 Armored Cable Application Scenarios

Exclusive Note for Overseas Customers

YJV22 is a special model under Chinese GB standards. This coding system is not adopted in overseas markets including Europe, America, Southeast Asia, and the Middle East. However, it is fully equivalent to international standard armored cables in structure, performance and parameters, with the corresponding models as follows:

✅ European / VDE Standard: N2XBY
✅ British / BS Standard: XLPE STA Armoured Cable
✅ General International Definition: Copper XLPE Insulated Steel Tape Armoured PVC Sheathed Cable (0.6/1kV)

All YJV22 cables comply with the IEC 60502 international standard. They are fully compatible and interchangeable with global mainstream armored cables in electrical performance, mechanical protection and application scenarios, suitable for various engineering projects worldwide.

YJV22 armored cable is an essential product for various underground power distribution projects. Many clients cannot tell the difference between YJV22 and ordinary YJV cables. This article gives a full and clear introduction.

1. What is YJV22 Cable?

YJV refers to XLPE insulated and PVC sheathed power cable.

The number "22" stands for double steel tape armor + outer PVC sheath.

Based on ordinary YJV cable, it is equipped with an additional steel tape protective layer, featuring compression resistance, anti-rodent damage and external force resistance. It is specially designed for laying environments with mechanical damage risks.

2. Core Advantages

The inner XLPE insulation features high temperature resistance and large current-carrying capacity, ensuring long-term stable operation;
The steel tape armor layer provides excellent compression and impact resistance, preventing damage from rolling pressure and stone scratching during underground direct burial;
The outer PVC sheath is moisture-proof and soil corrosion resistant, perfectly suitable for outdoor underground environments;
Available in flame-retardant ZR-YJV22 and fire-resistant NH-YJV22 types to meet fire protection requirements of various projects.

3. Main Application Scenarios

Direct burial lines for municipal roads
Priority is given to YJV22 for cables directly buried under road sides and sidewalks where vehicle rolling and heavy load pressure exist.
Cable trench and road crossing conduit projects
Ideal for cable pipelines crossing heavy traffic roads and complex pipe network intersections to avoid cable breakage caused by construction and external force damage.
Outdoor underground power distribution for industrial plants
Suitable for outdoor main power lines, park street light lines and factory outdoor lines, effectively resisting heavy impact and rodent damage.
Outdoor pipe network and old power grid renovation for residential communities
Applied to building outdoor lines and green belt buried lines to reduce later damage and maintenance costs.
Outdoor underground cables for photovoltaic and wind power projects
Used for on-site power distribution of power stations. The armored structure protects cables from damage caused by gravel and mechanical construction in wild environments.

4. Inapplicable Scenarios

For fully indoor laying in cable shafts and bridge racks without external force risks, ordinary YJV cable is more cost-effective;
Special anti-corrosion cables are required for environments with long-term water immersion and strong acid-base corrosion.

Summary

YJV22 armored cable is the optimal choice for all directly buried, road crossing and outdoor soil laying power lines with risks of compression, excavation damage and rodent damage. It guarantees stable power transmission and reliable mechanical protection, helping projects pass acceptance smoothly.
