Superior Moisture & Water Resistance: The PE outer jacket exhibits near-zero water absorption, making it ideal for underground conduits.
Exceptional Budget Efficiency: Aluminum conductors drastically lower upfront procurement costs compared to traditional copper cables.
High Mechanical & Abrasion Resistance: Tough PE protection prevents surface scratches and tearing during cable pulling and installation.
Excellent Low-Temperature Flexibility: Operates reliably in harsh cold climates without brittle cracking of the outer jacket.
Lightweight Structure: Low density of aluminum reduces overall cable weight, easing structural loads on trays and support brackets.
Application
Underground Conduits & Ducts: Ideal for pulling through outdoor concrete pipes, plastic ducts, or wet drainage channels.
Chemical & Industrial Facilities: Power supply layout in industrial zones requiring higher chemical stability against soils.
Renewable Energy Plants: Perfect for cost-effective grid connections in extensive solar PV parks and remote wind farms.

FAQ
1. What unique mechanical and thermal benefits does XLPE insulation provide for this aluminum power cable?
High-Thermal & Dielectric Efficiency:
Our YJLY series aluminum power cable utilizes high-dielectric Cross-linked Polyethylene (XLPE) insulation for the continuous cores. Unlike standard PVC layers that degrade under high thermal stress, premium XLPE insulation allows the aluminum conductor to continuously operate safely at an elevated thermal threshold of 90°C. In the event of emergency grid short-circuits, it successfully manages sudden high thermal spikes up to 250°C for 5 seconds without mechanical meltdown, ensuring reliable power grid safety.
2. Why is a heavy-duty Polyethylene (PE) outer jacket preferred over standard PVC for underground conduits?
Impenetrable Moisture & Abrasion Shield:
Underground cable ducts and wet outdoor drainage channels are highly prone to chemical runoff and continuous moisture infiltration. Our XLPE aluminum power cable addresses this by implementing a rugged, specialized Polyethylene (PE) outer protective jacket. The chemical density of the outer PE sheath ensures near-zero water absorption, superb environmental stress-cracking resistance (ESCR), and outstanding resistance against soil alkalinity, securing a long-term service life exceeding 30 years.
3. How does specifying unarmored YJLY aluminum main lines optimize renewable energy plant budgets?
Metallurgical Economy & Structural Lightness:
Designed explicitly for extensive solar PV parks and remote wind farms, our unarmored cable incorporates high-purity electrical-grade (EC-Grade) Class 2 compacted stranded aluminum conductors. By opting for optimized aluminum instead of traditional copper main supply lines, initial metallurgical engineering expenditures are reduced by up to 60%. This structural lightness slashes cross-border maritime shipping fees and drastically decreases installation strain on supporting trays and brackets.
4. Is this 0.6/1 kV aluminum power cable suitable for severe cold weather deployment?
Excellent Low-Temperature Climate Flexibility:
Yes. Standard PVC jackets frequently turn brittle and crack when subjected to harsh cold-weather cable pulling and storage environments. Our PE jacketed aluminum line combats this issue seamlessly, maintaining outstanding physical elasticity and anti-tearing durability down to a brutal arctic environment threshold of -40°C. This makes it an exceptional engineering fit for remote northern infrastructures and outdoor open-air storage yards.
5. What manufacturing sizes and project logistics support does ZHONGYI CABLE guarantee for bulk orders?
Heavy-Duty Infrastructure Logistics & Project Support:
As an established direct B2B cable manufacturer, we engineer our unarmored YJLY aluminum main lines in single-core and multi-core clusters (spanning 1 to 4 cores) across heavy cross-sections from 10 mm² up to 630 mm². To prevent radial deformities or surface scratching during sea freight transit, bulk wholesale orders are wound securely on heavy-duty wooden drums, fully backed by complete Type Test Reports, CE, CCC, and ISO certificates to clear destination ports smoothly.
