JKLGYJ 10kV Aluminum Core Cross-linked Polyethylene Insulated Reinforced Overhead Cable

JKLGYJ is an insulated overhead conductor suitable for overhead distribution lines requiring weather resistance, safer spacing, and high tensile strength. It is ideal for power system upgrades, rural electrification, and long-span overhead lines.

JKLGYJ is typically supplied as a 10kV insulated overhead conductor (insulated conductor) with an aluminum-based conductor (usually reinforced with steel wire for increased tensile strength) and a cross-linked polyethylene (XLPE) insulation layer. This "insulated" design is designed to improve line safety and reduce the risk of failure due to accidental contact, tree branches, and exposure to severe weather compared to bare conductors.

JKLGYJ is not a fully sheathed underground cable. It is primarily used for overhead installation on poles/towers and should be selected along with the correct accessories, fittings, and overhead system installation methods.

Typically used in overhead distribution networks around 10kV (specific voltage level depends on the project). If your system is 6kV, 10kV, or other medium voltage distribution levels, please specify the rated voltage, insulation thickness, and standard requirements in your Request for Quotation (RFQ).

• Overhead Distribution Feeders and Branch Lines
• Rural Electrification and Grid Expansion
• Lines traversing densely vegetated areas; clad conductors reduce fault risk.
• Urban or Suburban Upgrades, prioritizing safety margins and minimizing outages.
• Mountainous areas, river crossings, and long spans requiring higher tensile strength.

• Surrounding Power Distribution at Factories
• Distribution Lines in Mining Areas and Rugged Terrain
• Temporary or Phased Construction Power Supply on Overhead Lines (where permitted by local regulations)

• Safer Overhead Line Cabling Strategies
• Clad insulation helps reduce accidental contact faults and improves the sense of security for lines in public corridors and narrow right-of-way areas.
• Superior Span Mechanical Performance
• Reinforced conductor options are typically used to handle higher tensile strength, longer spans, and complex terrain.
• Weather Resistance and Outdoor Durability
• XLPE insulation maintains stable outdoor performance under temperature fluctuations, sunlight exposure, and long-term overhead operation.
• Reduces the risk of line disruptions in actual corridors
• Commonly used in vegetated areas and areas where branches meet, as exposed conductors are more prone to tripping in these areas.
• Faster utility-grade installation
• Equipped with matching connectors, terminals, lifting clamps, and connection hardware, it is ideal for pole and line installation processes.

• Conductor: Aluminum stranded conductor (optional: steel wire reinforcement for increased tensile strength)
• Insulation: Cross-linked polyethylene (XLPE)
• Optional Outer Layer: Depends on the project (some specifications may include a protective sheath)
• Core: Overhead lines typically use single-core conductors
• Installation Method: Overhead, secured to poles/towers using specialized hardware

• Conductor Stranding
• Aluminum stranded wire is stranded to achieve the required conductivity and flexibility; a steel core can be added as needed to increase tensile strength.
• Insulation Extrusion
• XLPE insulation is extruded with controlled thickness and concentricity to ensure the performance of overhead power systems.
• Crosslinking and Curing
• XLPE is crosslinked to improve its thermal and mechanical stability.
• Surface and Marking
• Surface quality and continuous marking are controlled to ensure traceability, installation identification, and project acceptance.
• Routine Inspections
• Typical inspection items include conductor resistance, insulation thickness, spark/voltage tests according to applicable standards, and dimensional inspections.

Question 1: What is JKLGYJ mainly used for?

Answer: Mainly used for overhead distribution lines, where covered conductors are used. Compared to bare conductors, JKLGYJ is better suited for improving line safety and reducing the risk of failure.

Q2 Is JKLGYJ suitable for long-span lines?

A Many projects choose reinforced conductors for long-span and high-tension lines. Span requirements, sag requirements, and mechanical loads must be confirmed during the design phase.

Q3 What is the insulation material for JKLGYJ?

A Typically, cross-linked polyethylene (XLPE) insulation is used to meet the performance requirements of outdoor overhead lines.

Q4 Can JKLGYJ replace underground medium-voltage cables?

A No. JKLGYJ is primarily used for overhead lines. Underground line systems typically require different cable structures, protection measures, and installation methods.

Q5 What accessories are needed?

A Typical overhead line hardware includes suspension and tension clamps, connectors, and line protection accessories. Specific configurations depend on pole design, span, and local power company specifications.

Q6 What information is needed for an accurate quote?

A requires the following information: rated voltage level, conductor structure (with or without reinforcement), specification list, total length in meters, roll diagram, destination, standard requirements, and necessary documentation.
