Fifty-Foot Self-Retracting Reel for Demanding Static Grounding Applications

June 28, 2011

The new VESM02 cable reel is specifically designed to provide secure static ground protection for difficult field applications such as tanker trucks, rail cars, IBCs, and mobile tanks or drums. In these cases, typically, the equipment to be grounded may be some distance away from a proven grounding point and an outdoor location limits the use of permanently exposed cables. Further, the need for a continuously monitored connection to ground can be even more problematic. VESM02 self-retracting reels are housed in a durable, light-weight steel housing with a powder-coated finish, suitable for use outdoors or indoors per NEMA 4 / IP 56 / ingress protection. The reel is fitted with 50 feet of Cen-Stat™ Static-Dissipative Hytrel™ protected cable with an adjustable ball stop. The stop is held under constant tension by a spring/auto-locking device. And, as a convenience, the main cable is pre-terminated by an additional 10 feet of two-conductor cable, configured to facilitate direct connection to the appropriate Earth-Rite grounding system (either flex cable or conduit). The precision slip-ring assembly has a special ultra-low resistance design making it suitable for monitoring extremely low grounding and bonding resistance values such as a value of 10 ohms as recommended by all major international static control technical standards and industry guidelines.
