Dual-Layer Moisture Barrier: Combining a 100% water-resistant PE outer jacket with metallic steel tapes ensures maximum reliability in marshy soils.
Heavy-Duty STA Protection: Double steel tape armor shields the interior matrix from underground stones, soil shifts, and external compaction.
Excellent Pest & Rodent Immunity: The rigid metallic armor wrap provides a hard mechanical shield against subterranean pests and termites.
Optimized Project Procurement Budget: Stranded aluminum conductor minimizes initial engineering material investments compared to copper equivalents.
High ESCR & Low-Temp Survival: The PE jacket ensures the cable does not suffer structural cracking under long-term thermal stress or arctic temperatures down to -40°C.
Application
Direct Underground Burial: Laid directly in excavated soil trenches without any extra protection tubes or concrete ductbanks.
Wet & Saline Terrains: Power grids crossing coastlines, agricultural irrigation zones, swamplands, and high water-table areas.
Industrial Infrastructure: Main energy distribution loops for mining sites, heavy chemical complexes, and remote storage yards.

FAQ
1. Why is the combination of an XLPE core insulation and a PE outer jacket ideal for YJLY22 cables?
Dual-Layer Moisture & Thermal Protection:
Our YJLY22 aluminum power cable utilizes high-dielectric Cross-linked Polyethylene (XLPE) insulation for the individual cores paired with a rugged Polyethylene (PE) outer protective jacket. While the XLPE matrix allows the conductor to continuously operate at a high thermal threshold of 90°C, the chemical density of the outer PE sheath provides superior moisture resistance, high environmental stress-cracking resistance (ESCR), and structural integrity against aggressive soil chemicals, preventing water treeing degradation in damp underground trenches.
2. What engineering mechanical defense does the Double Steel Tape Armor (STA) provide for direct burial?
High Radial Compression & Crush Resistance:
The designation ’22’ in the YJLY22 framework indicates a robust Double Steel Tape Armored (STA) layer wrapped spirally around the inner bedding matrix. Underground power distribution lines are constantly subject to crushing loads from heavy surface transport and sub-soil shifting. This hard metallic shield provides exceptional radial crush protection and subterranean rodent immunity, allowing utility engineers to safely route these lines via direct burial without forcing the use of rigid protective conduit banks.
3. How does specifying standard YJLY22 aluminum main lines optimize modern project procurement budgets?
Metallurgical Weight & Material Economy:
Our 0.6/1 kV armored cable incorporates high-purity, electrical-grade (EC-Grade) Class 2 stranded aluminum conductors. By opting for optimized aluminum instead of standard copper equivalents, total physical cable weight is reduced by roughly 40% to 50%. This structural lightness slashes cross-border maritime shipping fees, facilitates physical handling during trench layouts, and lowers initial metallurgical engineering expenditures by up to 60% without compromising power grid continuity.
4. Does the PE sheathed aluminum armored cable remain durable under arctic freezing conditions?
Extreme Low-Temperature Low-Temp Survival:
Yes. Traditional PVC outer jackets tend to turn brittle and crack under extreme cold-weather installation and storage environments. Our YJLY22 armor lines combat this through their heavy-duty specialized Polyethylene (PE) outer formulation, which maintains outstanding physical elasticity and anti-tearing durability down to a brutal arctic threshold of -40°C. This makes it an exceptional engineering fit for remote northern mining infrastructures and outdoor high-latitude open-air yards.
5. What wholesale manufacturing cross-sections and logistics support does ZHONGYI CABLE guarantee?
Heavy-Duty Infrastructure Logistics & Project Certification:
As an established direct B2B cable manufacturer, we supply YJLY22 STA aluminum cables in single-core and multi-core clusters (including 4-core, 5-core, and 3+1 structures) spanning heavy cross-sections from 10 mm² up to 630 mm². To prevent physical deformities or armor displacement during ocean transit, all wholesale orders are wound securely on heavy-duty steel-wooden drums or reinforced reels, fully backed by complete Type Test Reports, CE, CCC, and ISO factory certificates.
