JKLV is a dual-class low/medium voltage overhead insulated cable featuring a compact stranded aluminum conductor and high-performance weather-resistant PVC insulation. Its voltage ratings cover 0.6/1kV low to 10kV medium, and it is designed for global outdoor overhead power distribution, municipal transmission, and grid upgrade projects.

This cable combines lightweight construction, stable conductivity, excellent weather resistance, and high cost-effectiveness, fully meeting the needs of global power engineers, EPC contractors, power companies, and B2B bulk purchasers. JKLV integrated insulation structure replaces traditional exposed overhead conductors, improving line operational safety, saving corridor space, and reducing daily inspection and maintenance workload.

JKLV is manufactured in strict accordance with international and national industrial standards, offering a complete range of specifications and stable and reliable operation. It can adapt to various complex terrains, high temperatures, extreme cold, coastal salt spray, and high humidity environments, making it the preferred standard solution for urban power grid upgrades, rural electrification, industrial park power supply, and municipal infrastructure projects.

• IEC 60502, IEC 60287, CE certification, RoHS compliance, ISO 9001 Quality Management System, ISO 14001 Environmental Management System

• GB/T 12527-2008, GB/T 1179, GB/T 14049, DL/T 5221 Fully compliant with global overhead line design codes, wind and ice load design codes, coastal corrosion protection technical specifications, and municipal power grid construction specifications.
  

Main Application Scenarios

• Low-voltage and medium-voltage overhead trunk lines and branch lines in urban and rural power grids
• Rural electrification, power supply to remote villages, and cross-sea overhead power transmission to islands
• Outdoor power layout in industrial parks, chemical industrial zones, manufacturing bases, and logistics parks
• Overhead distribution networks in coastal high-humidity, salt spray, and tropical high-temperature areas
• Power supply systems for municipal engineering, highways, and railways, as well as street lighting transmission systems
• Construction sites, mining areas, and temporary outdoor fixed overhead power lines
• Power grid renovation projects involving the replacement of old bare conductors in densely populated areas and forested regions

• Enhanced Line Operation Safety: The integrated, enclosed insulation structure effectively isolates the line from external contact, preventing the entry of branches, wild animals, and foreign objects. This significantly reduces the potential risk of short circuits and grounding faults, improving the overall safety of overhead lines in densely populated areas, forested regions, and roadsides.
• Low Maintenance Requirements: The robust mechanical structure resists wind pressure, minor mechanical shocks, and long-term weathering. Stable operation reduces the frequency of routine inspections and subsequent replacements, ensuring long-term stable operation of the power grid.
• Comprehensive Specifications and Customization: A complete range of standard voltages and cross-sectional specifications are available for easy selection. Conductor sizes, insulation thicknesses, and enhanced corrosion-resistant formulations can be customized to project span, load current, and local environmental conditions.

• Standardized Production and Comprehensive Inspection Control: All products are manufactured in accordance with IEC and GB standards. Each batch undergoes withstand voltage testing, insulation resistance testing, mechanical tensile testing, and aging performance testing. We provide complete certification documentation and test reports for project bidding and acceptance.
• Professional Engineer Technical Support: We offer free current-carrying capacity references, overhead line parameter guidance, model selection advice, and layout consultation. Official datasheets, technical manuals, and supporting engineering documents are available to support EPC and utility project applications.
• Global Export Packaging and Stable Delivery: Export-standard steel and wooden drum packaging ensures moisture and pressure protection, suitable for long-distance sea and land transport. Flexible trade terms and stable delivery cycles for large orders meet global engineering procurement needs.
• Optimized Lifecycle Benefits: Direct sales from the manufacturer effectively control initial procurement costs. With a design life of over 25 years, low energy transmission loss, and low daily maintenance input, optimized lifecycle expenditures create stable overall returns for global buyers and engineering contractors.

1. Select appropriate low-voltage or medium-voltage conductors based on the system voltage level, and match the suitable conductor cross-sectional area according to the actual load current and laying span. Confirm the current-carrying capacity matching during the early design phase of the project.
2. In coastal, chemical, and high-humidity areas, use reinforced salt spray-resistant and corrosion-resistant JKLV type conductors to adapt to the local atmospheric environment.
3. During installation, adhere to the specified minimum bending radius; avoid forced bending and compression to protect insulation integrity and maintain long-term electrical stability.
4. Laying work must not be carried out when the ambient temperature is below -20℃; for areas with large seasonal temperature differences, sufficient expansion allowance should be reserved.
5. Select matching aluminum alloy clamps and connectors with consistent material properties to avoid localized overheating and ensure the long-term reliable operation of the entire overhead line system.
