Metal-clad cables having a metal sheath potentially provide a low impedance and reliable ground path in order to function as an equipment grounding conductor. One type of such cable described in U.S. Pat. No. 6,486,395, assigned to the assignee of the present invention, contains a conductor assembly having at least two electrically insulated conductors cabled together longitudinally into a bundle and enclosed within a binder/cover. A bare grounding conductor is cabled externally over the binder/cover, preferably within a trough/interstice formed between the insulated conductors. In one type of metal-clad cable, the metal sheath is helically applied to form an interlocked armor sheath around the conductor assembly, and the bare grounding conductor is adapted to contact the sheath to provide the low impedance ground path.
However, in order to maximize the structural integrity of these and other types of cables, it is important that the conductors disposed within the metal clad cable be configured to withstand the various forces exerted on the cable during manufacturing, storage and/or installation. One solution is to enclose the conductors within the binder or cover to provide additional stability to the conductors disposed therein, especially additional strength against crushing forces. Another solution includes providing a talc powder around the conductors and beneath the binder/cover, providing a talc powder between the binder/cover and outer sheath and/or wrapping a Teflon wrap around each conductor (and talc, if present) prior to applying the binder/cover, in order to improve abrasion resistance, especially during flexing of the cable. However, cables having such configurations are costly to manufacture and can complicate manufacturing and field installation. For example, when terminating a cable, the binder/cover and Teflon wrap oftentimes remain exposed and must be separately cut or peeled away from the conductor assembly. This results in increased unnecessary material waste and increased labor costs.
Embodiments provided herein contain an improved electrical cable of the type having an outer sheath enclosing a conductor assembly. The conductor assembly comprises a plurality of insulated conductors with a strength enhancer to provide increased resistance against crushing forces thereby obviating the need for a binder/cover disposed around the conductor assembly. According to embodiments disclosed herein, the strength enhancer may include a silicone oil, an erucamide and/or generally increasing the thickness of the conductor insulation such that, for example, the cable conforms to the performance criteria established by UL 1569.
In addition, embodiments provided herein include a method of increasing crush resistance of an electrical cable having an outer sheath enclosing a conductor assembly. In particular, methods disclosed herein provide for insulating one or more conductors, wherein insulating the one or more conductors includes providing a strength enhancer within the insulation and enclosing the insulated conductors with the outer sheath, wherein the electrical cable has increased crushed resistance without the need for a binder/cover.
For a more complete understanding of the present invention, including additional features, objects and advantages thereof, reference is now made to the following detailed description, taken in conjunction with the drawings, in which:
In the description which follows, like parts are marked throughout the specification and drawings with the same reference numerals, respectively. The drawings may not be to scale and certain features may be shown exaggerated in scale or in somewhat schematic form in the interest of clarity and conciseness.
As seen in
Covers 22, 24 and 26 of
Embodiments described herein provide an improved flexible cable 10 and method of making a flexible cable 10 having improved crush resistance comprising insulated conductors 18 and 20 each having a strength enhancer applied therein and/or thereto to enable cable 10 to be fabricated and used without cover(s) 22, 24, 26 and still maintain the mechanical performance characteristics such as those required under UL 1569. For example, as illustrated in
In the embodiment illustrated in
Preferably, the size of inner and outer regions 34 and 36 is dictated by performance criteria established by UL 1569. For example, UL 1569 describes various performance tests required of the finished cable (i.e., cable 10), one of which includes a crushing test. Inner and outer regions 34 and 36 are dimensioned based on performance criteria established in UL 1569 to determine the necessary thickness such that when cover 22, 24 and/or 26 is removed from conductor assembly 12, enhanced insulation 32 performs the functions that are otherwise performed by cover(s) 22, 24 and/or 26.
Additionally or alternatively, strength enhancer can include either a silicone oil or erucamide, which has been found to increase the crush resistance of insulation 32. In accordance with the testing subsequently described, it has been found that the crush resistance of an insulated wire sample having a silicone oil applied thereto is increased by almost 30% compared to an insulated wire sample not having a silicone oil applied thereto.
In accordance with one testing method, a pair of insulated conductors and a bare grounding conductor were wrapped within a metallic sheath. One cable contained pair of insulated conductors having a silicone oil applied thereto and the other cable contained a pair of insulated conductors without any silicone oil or strength enhancement applied thereto. The respective sizes of the conductors and cables were identical.
A force was applied to the cable assembly in accordance with UL 1569 and the force values, as listed in Tables 1 and 2 below, were determined. In particular, the cables were crushed between flat and horizontal steel plates in a compression machine. A solid steel rod was secured to the upper face of the lower steel plate and the cable was placed in between the steel plates and on top of the solid steel rod. Three separate cables were tested for each cable type (i.e., the strength enhanced and non-strength enhanced) at ten different points along the respective cables. During testing, the plates were compressed with increasing force on the cable until it was determined that contact had occurred between the conductors or between one or more of the conductors and the grounding conductor, the armor or both. Table 1 illustrates the test results without the strength enhancer. Table 2 illustrates the test results with conductors having the strength enhancer. As seen, the strength enhancer provided an increase in performance of almost 30% over the cable that did not utilize the strength enhancer.
According to some embodiments, insulation 32 contains 0.25-0.85% of erucamide and a stearyl erucamide mixed into the conductor insulation 32. According to some embodiments, the silicone oil is a high molecular weight silicone oil. For example, the concentration, by weight, of the high molecular weight silicone oil is at least 9% by weight of the conductor insulation 32.
As is therefore evident, the strength enhancer can be mixed with the material from which the insulation is to be extruded prior to extrusion or, alternatively, introduced into the extruding head for subsequent mixing with the molten extrusion material as the sheath is being formed. As a further alternative, the strength enhancer can be initially compounded with the polymeric material of the pellets themselves in a process upstream of that depicted in
Polymeric materials that can be used for insulation 32 include polyethylene, polypropylene, polyvinylchloride, organic polymeric thermosetting and thermoplastic resins and elastomers, polyolefins, copolymers, vinyls, olefin-vinyl copolymers, polyamides, acrylics, polyesters, fluorocarbons, and the like.
According to some embodiments, in addition to increasing crush resistance, it has been found that the strength enhancer can be used to increase the abrasion resistance of insulation 32. For example, cable 10 is oftentimes provided with talc powder disposed around conductors 18, 20 and beneath the binder/cover 22. In some applications, a talc powder can also be disposed the binder/cover and outer sheath, which is used to increase the abrasion resistance of conductors 18 and 20, especially during flexing of cable 10. Additionally, a Teflon wrap can be applied around each conductor (and talc, if present) prior to applying the binder/cover, in order to improve abrasion resistance. However, it has been found that applying silicone oil or erucamide also acts to, in addition to increasing crush resistance of conductor insulation 32, increase abrasion resistance.
Although specific embodiments have been described in detail, those skilled in the art will also recognize that various substitutions and modifications may be made without departing from the scope and spirit of the appended claims.
This application is a continuation of co-pending U.S. patent application Ser. No. 12/792,642, filed Jun. 2, 2010, now U.S. Pat. No. 10,325,696, the contents of which are incorporated herein by reference in its entirety.
