OKI Electric Cable provides the “ORP-D Cable Series,” power cables for moving parts rated at 600V. The ORP-D is a high-flex power cable for robots that uses a proprietary special elastomer insulation, achieving excellent flexibility and a reduced cable diameter. Despite its excellent flexibility, the ORP-D has been reduced in diameter to a level equivalent to conventional 300V-rated products, providing greater flexibility in wiring design where installation space is limited.
In terms of technical characteristics, the ORP-D complies with UL 758 Style 2586 (105°C, 600V). In proprietary durability tests, it has demonstrated flexibility performance of more than 100 million sliding flexing cycles, more than 20 million swing flexing cycles, and more than 20 million torsional cycles. Its electrical performance includes a dielectric withstand voltage of AC 2000V/min and an insulation resistance of 100 MΩ·km or higher at 20°C. The operating temperature range is -10 to 105°C, and the sheath is made of heat- and oil-resistant PVC. The flame resistance complies with VW-1. The product lineup includes the unshielded “ORP-D ①SQ ②C (2586)” and the shielded “ORP-D ①SQ ②C (SB) (2586),” which uses a tinned annealed copper wire braid for shielding. Conductor cross-sectional areas range from 0.5 to 5.5 mm², with 2 to 10 cores. The minimum allowable bending radius is 4 times or more the cable outer diameter for fixed sections, and 6 times or more for moving sections for unshielded cables or 8 times or more for shielded cables.
The main applications are moving parts of conveying equipment, inspection equipment, FPD manufacturing equipment, and other machinery. The cable is also suitable for the arms and rotary sections of articulated robots, including welding and assembly robots, as well as the sliding sections of single-axis and Cartesian robots such as mounters. It is suitable for the robotics industry and FA applications such as machine tools and manufacturing equipment where high-voltage capability and space-saving wiring are required.
The ORP-D combines a 600V rating with a reduced diameter and flexibility, making these characteristics important considerations when installing the cable in compact equipment or considering replacement of 300V-rated cables. We sell the ORP-D through our online shop in 10-meter increments as cut lengths, as well as in standard lengths. Please place your order through the product page below.
