Product Introduction

JKLYJ is the most widely used and cost-effective aerial insulated cable in overhead distribution networks rated at 1kV and below: aluminum conductor + cross-linked polyethylene (XLPE) insulation, specifically designed to replace traditional bare conductors (such as aluminum stranded wires), and widely used in overhead fixed installation applications including urban distribution network main lines, rural power grid renovation, and industrial park power distribution. It combines the lightweight economy of aluminum with the electrical advantages of XLPE's 90℃ temperature rating, making it the "mainstay aerial cable model" under the GB/T 12527-2008 standard system.
