From simple to intricate applications, we partner with our customers to fabricate their assemblies to their required specifications using cost effective solutions.

Our team will work with you from your initial design through the prototyping process until the final approval for production is achieved. We can print the unique components required for your small production runs or for rapid proto typing.Wire Rope Options

NextControl cables are used in any application where mechanical actuation or mechanical force needs to be used to actuate something between 2 fixed points. There are 4 main components used in the manufacturing of these assemblies. Conduit/Casing, Conduit Fittings, Wire/Wire Rope and Wire Rope End Fittings.

Control cable assemblies are used in numerous applications requiring the transmission of force.  Especially if the force needs to be routed around bends in varying directions. Some industries that use control cable assemblies and wire pull rope are: Aircraft, Lawn and garden, Exercise equipment, Medical, Automotive, and Office equipment.

When designing a control cable assembly or push pull conduit, some factors to consider are:The amount of force needed to be transmitted, orworkload factor.

When designing a push-pull cable assembly, the workload in the push mode is potentially critical. As the moving inner wire meets resistance, the wire could possible distort or buckle, especially the portion of the inner wire that extends from the conduit. By increasing the inner wire diameter you can increase the workload in the push direction. A push-pull wire rope assembly is stiffer by nature; therefore, larger bend radii are required for smooth motion of the inner wire.

When designing a pull assembly, the workload is a function of the breaking strength inner cable tempered with a safety factor. The inner push pull cable conduit for pull assemblies can be much more flexible, allowing tighter bend radii when routing the assembly.When designing either style of assembly, other details for consideration.How the assembly is mounted to reduce the conduit deflecting under tension.  Using clamps and /or end fitting to properly secure the assembly is important.

Loss of motion is another potential problem and can be caused by two variables. One is the deflection of the conduit under tension. Second is relative to the total amount of direction change and the clearance between the ID of the conduit and the OD of the core cable.  Due to this loss of motion, the length and diameters of the assembly"s conduit and inner wire are understandable important considerations. One inch travel on the input side of an assembly, does not necessarily mean one inch travel on the output side

Ansul fire protection products were introduced to the marketplace in 1939 featuring the first cartridge-operated, dry chemical fire extinguisher. As technology changed and dangerous new hazards emerged, Ansul product engineers worked hand-in-hand with many industries to protect their people and property from fire. Today, the Ansul Fire Technology Center and Center of Excellence houses one of the most extensive fire research and testing facilities in the world. No other fire protection brand is supported by such extensive broad-based research and test facilities with so many scientists and engineers devoting 100% of their time preparing for the fire protection and safety needs of the future.

In this Blog, NEPTCO answer questions regarding their advanced specification MULETAPE which includes a comparison to using traditional cable pulling ropes.

A: When polypropylene rope is pulled through PVC or polyethylene duct, the friction generated by the rope rubbing against the conduit wall creates enough heat to actually “burn through” the

A:Aside from damaging the conduit or cable duct and creating opportunities, the jagged edges of the burned conduit pose a real threat to the cable installed by the contractor.

Cable surging through the damaged conduit or duct at an average rate of 100 ft. per minute will catch on the damaged areas of conduit, shredding the outer jacket. Fibre Optic cables are particularly vulnerable since the situation which can lead to excess tension and can cause micro-bending. As a result, the cable may fail prematurely, or simply not function at all.

A:NEPTCO has gone to great lengths to test this theory by duplicating installation conditions in the lab and in the field. Their research engineers designed the Duct Cut Tester to evaluate the performance of various conduit materials and winch lines under typical installation conditions.

The results tabulated on the reverse side of this sheet are conclusive: pre-lubricated MULETAPE out-performs polypropylene rope in every installation scenario.

A: MULETAPE is pre-lubricated, which helps reduce friction and the heat it generates, but MULETAPE’s wide and flat profile is also important. A round rope will concentrate all heat and energy on the small area where the rope comes in contact with the innerduct. MULETAPE is flat, and therefore spreads this heat and energy across a wider area, reducing the chance of burn through.

A: Absolutely. If you have ever experienced a rope breaking during a pull, it is caused by the cable getting snagged on a duct that has been burned through.  The rope is usually narrower than the cable and pulling sock and is able to make its way back into the duct, however, because the cable and pulling sock are wider they may not be able to make their way back into the duct.  When this happens, the tension rises, the pull becomes more difficult and the rope may break.  This not only causes a health and safety hazard, the possibility that the cable is damaged is extremely high.  In 1999, NEPTCO recreated a typical installation scenario in an above-ground test. The results were just as expected – the rope burned through the conduit in seconds, while the MULETAPE caused no damage.
