Locking Cable

An urgent need for a fast reliable fastener security system for the Nuclear Power Industry resulted in the further expansion of Safe-T-Cable (Locking Cable) by DMC. Working with a major contractor to NAVSEA and commercial power organizations, DMC developed and certified a .062 diameter Safe-T-Cable for use onboard nuclear submarines, and carriers. The .062 diameter Safe-T-Cable (Locking Cable) was later tested and certified for use by the commercial power industry, aircraft applications, and industrial use. The practice of twisting lockwire onto fasteners and threaded assemblies is a tedious task, which requires skill and time. Lockwire measuring .062 diameter is anything but “user friendly”. Safe-T-Cable (Locking Cable) allows maintenance and other operations to be performed in the minimum time, in tight access areas, with limited inspection, and with no rework due to faulty lockwiring. Also, handling the tool and materials for Safe-T-Cable (Locking Cable) will not damage special gloves or protective clothing.

.032 and .062 diameter Safe-T-Cable (Locking Cable) is recognized and defined in MIL-STD-763 (G Revision).

Construction

The standard .062 diameter Safe-T-Cable (Locking Cable) is 24 inches in length, and measures .062 min./.072 inch max. diameter. The cable is comprised of 7 strands of 19 wires each for maximum strength and flexibility. The factory-applied end fitting (square) measures approximately .155 inch across the flats, and the outside diameter of the user applied ferrule measures .150 inch. The minimum pull-off load of the ferrule after crimping is 280 pounds (per Mil-Std 763). Product samples, application information, and technical data may be obtained by contacting DMC. Two application tools are available from DMC, and two installation kits are also available.

SCTE625B Battery Powered Hydraulic Application Tool

SCTEB625The Battery Powered Hydraulic Application Tool (part number SCTE625B) crimps and cuts the assembly flush to the ferrule by pressing a trigger. This tool is lightweight and self-contained. The Lithuim Ion battery
is rechargeable (charger supplied).

SCTH625 Hydraulic Application Tool

The Hydraulic Application Tool (part number SCTH625) utilizes a lightweight hand actuated hydraulic pump to develop the force required to crimp and cut the .062 diameter Safe-T-Cable (Locking Cable). The tool crimps and cuts the assembly flush to the ferrule by multiple actuation of a single handle.

Both application tool models feature an easy to use adjustable tension clutch mechanism with a rotary tension wheel, replaceable crimp nose assemblies, and user adjustable crimp depth settings for maximum tool life/performance.

Other accessories offered by DMC include a Torque Verification Block (SCT-TB2) for periodic monitoring of application tool performance, a 100-750 inch-pound torque wrench (SCT-D011), and other tool accessories.
