Product Overview
Jumper Cable 5kV/15kV ASTM B173/B33 is a high-performance, flexible medium-voltage cable designed for temporary power connections and industrial applications requiring durability and reliability. Featuring ASTM-compliant tinned copper conductors, ethylene-propylene rubber (EPR) insulation, and a thermosetting CPE jacket, this cable operates in extreme temperatures (-40°C to +90°C) and resists water, abrasion, and environmental stress. Ideal for utility maintenance, mining, and emergency power systems, it ensures safe and efficient power transmission in demanding conditions.
Key Features
