PVC Pendant Overhead Crane Cable 300/500V Flexible Copper XLPE Insulated with Steel Suspension Strands for Industrial Crane Control Applications

Product Overview

This PVC pendant overhead crane cable is a specialized flexible control and power cable designed for safe and reliable remote operation of overhead crane systems via pushbutton control boxes. Engineered with integrated lateral suspension steel strands, the cable is optimized for suspended installations where the hanging length does not exceed 50 meters.

It is suitable for both indoor and outdoor environments requiring high mechanical durability, oil resistance, and excellent flexibility under continuous dynamic motion.

Application Scope

This crane control cable is specifically designed for:

• Overhead crane pendant control systems

• Mobile pushbutton control stations

• Hoisting and lifting equipment

• Suspended cable systems with lateral movement

• Industrial environments requiring frequent cable flexing

The design ensures stable performance in applications where mechanical stress, bending, and torsional forces are continuously present.
