Application

These cables are designed for use with autonomous sewer robots.
These robots are used to inspect municipal sewer networks and if necessary to locate leaks or blockages. Some of these robots are even able to seal such leaks after detecting them. Besides conductors for power supply, they also contain data cables, hoses for various drives, and coaxial cables for the video camera mounted on the robot.

= The product is conformed with the EC Low-Voltage Directive 73/23/EEC and 93/68/EEC.

Properties

To enhance reliability and tensile strength, a high-tensile and high-torsion resistant Kevlar braid is incorporated into the extremely robust PUR jacket

Part No. 74540+76397

PUR jacket: low adhesion, extremely abrasion resistant, halogen-free, resistant to UV, oil, hydrolysis and microbial attack

Part No. 70581

Special PVC jacket, largely oil resistant, self-extinguishing and flame retardant, test method B acc. to DIN VDE 0472 part 804 and IEC 60332-1, chemical resistant (see table Technical Information
