High-Voltage Continuous-Flex Flat Cable

Use For: Automation, Continuous Motion
Continuous Flex
Temperature Range: -85° to 325° F
Insulation: Silicone Rubber

Rated to 17,000 volts AC or higher, this cable is often used in oil drilling, robotics, and festoon systems. It withstands continuous motion without degrading data or signal transmission. With a flat shape, it’s good for tight spaces. It meets UL 94V0 for flame retardance.

Bend radius is the point to which the cable will bend without being damaged. It is measured from the center of the bend to the edge of the cable. The smaller the measurement, the tighter the bend.

High-Voltage Cable

Use For: Power Supply, Outdoors
Flexible
Temperature Range: -40° to 190° F
Insulation: EPDM Rubber

Often used in mining equipment, submersible pumps, and drilling rigs, this cable withstands 2,000 volts AC/DC. It meets Mine Safety and Health Administration (MSHA) standards for material quality. The EPDM insulation resists abrasion, so it can be pulled over rough surfaces without damaging the wires inside.
