Overhead Insulated Cable Aluminum Conductor Cable JKLYJ Wire 1KV Single-core Overhead Cable

JKLYJ cable is a 1kV single-core overhead insulated cable featuring aluminum conductor and XLPE insulation. Designed for fixed overhead power distribution lines of AC rated voltage 1kV and below, this cable is widely used in urban and forest area power grid reconstruction projects, where reliability and weather resistance are critical requirements.

Key Features and Advantages

Compared to bare conductors and PVC-insulated overhead cables, JKLYJ offers the following benefits:

• Weather Resistance: The XLPE insulation is formulated with weather-resistant additives, ensuring stable electrical performance under UV exposure, moisture, and temperature fluctuations.
• Higher Operating Temperature: With 90°C continuous rating (vs. 70°C for PVC or PE insulation), the cable allows higher current-carrying capacity for the same conductor size.
• Excellent Mechanical Performance: The cross-linked structure of XLPE provides enhanced toughness and resistance to deformation during installation and long-term service.
• Improved Safety: Insulated design reduces risk of phase-to-phase or phase-to-tree contact incidents common in bare overhead conductors, ensuring safer operation in populated areas and forest regions.
• Cost Efficiency: Aluminum conductor provides lightweight and cost-effective solution for large-scale utility projects compared to copper alternatives.

Specification

Product Features

● Rated voltage Rated voltage is 1, 10KV

●The working temperature of PVC and polyethylene insulation should not exceed 70 ℃, cross-linked polyethylene insulation should not exceed 90 ℃, and the duration should not exceed 5s in case of short circuit.

● The maximum temperature of the cable conductor PVC insulation should not exceed 160 ℃, polyethylene insulation should not exceed 150 ℃, cross-linked polyethylene insulation should not exceed 250 ℃, cable laying temperature should not be less than -20 ℃.

Application Fields

JKLYJ overhead insulated cable is suitable for the following applications:

• Overhead fixed installation for AC rated voltage 1kV and below

• Service drop cables (transformer secondary side connections)

• Urban power distribution grid reconstruction (rural and municipal utility projects)

• Forest area grid construction (weather-resistant design ensures reliable operation in varying climates)

• Converter transformer leading wires (soft aluminum conductor version available upon request)

The cable should be installed with a safe distance from trees. Short-term contact with tree branches is permitted under normal operating conditions.
