YJLHV22 is a next-generation power cable solution built for projects that need strong electrical performance without paying copper prices. By combining rare-earth aluminum alloy conductors with XLPE insulation and double steel tape armoring, it delivers:

Higher conductivity than conventional pure aluminum cables
Long-term stability and anti-aging performance
Significant total cost savings compared with copper-core designs

Why Choose YJLHV22?

Stronger Conductivity than Pure Aluminum - ≥ 62% IACS conductivity for reduced line losses
Reinforced Protection - Double steel tape armoring for secure direct burial
Built for Harsh Conditions - From municipal infrastructure to renewable energy sites
Optimized CAPEX + OPEX - Lower upfront cost vs. copper, longer life vs. ordinary aluminum

Understanding the Code: What "YJLHV22" Stands For

Structural Breakdown

Code	Structure Element	Function & Benefit
YJ	Cross-linked Polyethylene (XLPE) Insulation	Rated for continuous operation at 90°C, with low dielectric loss and strong resistance to thermal aging. Improves transmission efficiency by up to 18% compared with conventional insulation materials.
LH	Rare-Earth Aluminum Alloy Conductor	Alloyed with magnesium and silicon. Delivers conductivity of ≥ 62% IACS, outperforming standard pure aluminum conductors. Offers excellent resistance to creep, fatigue, and corrosion, with mechanical properties improved by around 30%.
V	PVC Sheath	Provides protection against moisture, oils, acids, and alkalis. Suitable for a wide range of outdoor and underground environments. Supports flame-retardant performance up to B1 class.
22	Double Steel Tape Armoring + PVC Outer Layer	Two layers of tightly wrapped steel tape significantly enhance compression and tear resistance—around 50% higher than single-armored cables. Offers strong defense against rodent and insect damage and enables direct burial without extra protective pipes in many designs.

Key Value Propositions

1. Alloy Conductor Upgrade - Electrical & Mechanical Performance in One

The rare-earth aluminum alloy core is engineered to outperform standard aluminum conductors:

Conductivity gain of roughly 5% compared with ordinary aluminum (≥ 62% IACS)
Long-distance power loss reduced by about 12%
High resistance to creep at elevated temperatures, greatly lowering the likelihood of loose terminations (up to 80% risk reduction at joints and connections)
Fatigue resistance of ≥ 10⁶ cycles, making it appropriate for routes that require repeated bending during installation
Service life expectation of 25+ years under typical operating conditions

2. Double Steel Tape Defense - Designed for Direct Burial & Concealed Routing

Mechanical protection is a core design target of YJLHV22:

Dual steel tape armoring combined with PVC outer sheath forms a rigid, protective shell
Withstands compressive forces up to 1200 N / 100 mm
Can typically be buried directly at approximately 0.6 m depth without additional conduit
Resilient under surface loads, minor ground settlement, and common construction activities
Performs well in demanding substrates, including rocky terrain and saline-alkali soils
Helps reduce or eliminate the need for extra protective piping, enabling shorter installation time and lower construction costs (project schedule reduction often up to 25%)

3. Cost Optimization - Smarter Investment Than Copper or Ordinary Aluminum

Versus copper-core cables:

Overall project spending (materials, logistics, and installation labor) can be 35-45% lower
Comparable current-carrying capability per cross-sectional area in many use cases
Particularly attractive for long-distance transmission and large-scale distribution networks, where meter-by-meter savings add up quickly

Versus standard aluminum-core cables:

Around 30% boost in mechanical strength
Approximately 50% better resistance to corrosion
More robust under high load and in harsh climates, translating to fewer interventions and reduced lifetime maintenance costs

4. Broad Application Range - One Cable for Many Environments

YJLHV22 supports multiple installation methods:

Direct burial
Conduit and ducting
Overhead (depending on local design and standards)
Cable trays and tunnels

Operational features:

Can typically be handled with regular tools; no specialized equipment is mandatory
Many smaller cross-sections can be laid or pulled by a single installer
Reliable from -40°C (no embrittlement) to +90°C continuous operating temperature
Suitable for high-altitude, coastal, and high-humidity conditions

Typical Application Scenarios

Municipal & Infrastructure

Urban road and bridge power supply upgrades
Street lighting and public facility distribution lines
Projects where trenching, backfilling, and construction loads are unavoidable

Residential & Commercial Projects

High-end residential complexes
Shopping centers, office buildings, and mixed-use developments
Concealed installations that demand long-term connection stability and minimal loosening at terminals

Industrial & Manufacturing Sites

Industrial parks, manufacturing plants, and warehouses
Medium-voltage and low-voltage distribution networks with large cable volumes
Scenarios requiring durable, budget-conscious long-distance runs

Harsh-Environment Locations

Coastal areas with salt-laden air
High-altitude regions exposed to large temperature swings
Humid and corrosive atmospheres (with appropriate engineering design and standards compliance)

Renewable Energy & Utility Corridors

Solar farms and wind power projects with extensive outdoor routing
Underground utility tunnels and integrated pipe corridors
Installations where double-armored protection reduces the need for additional anti-corrosion wraps or secondary mechanical protection

FAQ - YJLHV22 Power Cable

Q1: Is YJLHV22 suitable as a direct replacement for copper cables?

In many distribution and transmission applications, YJLHV22 can be engineered as an alternative to copper-core cables, offering comparable current-carrying capability per cross-section. The key advantage is a significantly lower project cost, with savings often ranging from 35-45% when you consider materials, transportation, and installation.

Q2: How does the rare-earth aluminum alloy improve reliability?

The alloy composition (including magnesium and silicon) increases conductivity and enhances mechanical strength. It also improves resistance to creep, which helps maintain tight, secure joints at terminals and connectors over time, especially under high temperature and load conditions. This reduces the risk of hot spots and unplanned outages.

Q3: Can this cable be buried directly in the ground?

Yes. The double steel tape armoring and PVC outer sheath are designed to withstand soil pressure, minor ground movements, and surface loads. In many designs, YJLHV22 can be laid directly in trenches at around 0.6 m depth without extra mechanical protection, provided local standards and engineering guidelines are followed.

Q4: What environments is YJLHV22 not recommended for?

YJLHV22 is robust, but for extremely specialized environments—such as areas with very high mechanical impact, extreme chemical exposure beyond standard industrial conditions, or special explosion-proof zones—project-specific engineering evaluation is required. In such cases, a customized design or different cable type may be more appropriate.

Q5: Does installation require special training or dedicated equipment?

No. The cable can be installed using standard industry tools and practices. Crews familiar with traditional aluminum or copper power cables will adapt easily to YJLHV22. The improved flexibility and fatigue resistance also simplify pulling and routing, particularly in complex cable tray systems or congested ducts.

Q6: How can I confirm the optimal cable size for my project?

Provide your load data, route length, installation method, and environmental conditions. Our technical team can then recommend appropriate cross-sections and configurations to meet voltage drop, current-carrying, and safety requirements according to relevant standards.
