QWhat does the outer jacket do? What is it made of?AThe jacket is both armor and advertisement; it protects the cable from damage and enhances the marketability of the assembly. As armor, the jacket must resist abrasion, impact, moisture and sometimes hostile chemicals (Bud Light, for instance). As advertisement, it may be distinctively colored or printed with the name of the manufacturer or dealer for product identification. The materials used for jacketing are the same type as those used for the inner insulation (thermoset or thermoplastic), but the choice is dictated less by electrical criteria and more by physical durability and cosmetic acceptability.

QWhat is the best cable jacketing material?AFor years rubber or neoprene were preferred for their superior abrasion resistance and flexibility, but modern thermoplastic technology has produced a number of PVC compounds that are soft and flexible but also very tough. As previously noted, thermoplastic processing is cheaper, faster and more predictable than that for thermoset materials. Only very specialized situations requiring oil or ozone resistance or extremes of temperature and climate demand neoprene or Hypalon jacketing. The use of PVC has two other major advantages. PVC is not as elastic as rubber or neoprene, and this lack of “stretch” lends additional tensile strength to the resulting assembly by taking some of the strain that would otherwise be borne solely by the center conductor. This has made a dramatic improvement in the reliability of currently manufactured instrument cables. The other important property of PVC is its almost limitless colorability. Once found only in gray or “chrome vinyl,” PVC-jacketed cable now ranges from basic black through brilliant primary colors to outrageous “neon” shades of pink and green.

QWhen the bank don't think, have been met the shipping documents included in the"clean on board "conditions?AWhen the bank don't think, have been met the shipping documents included in the "clean on board" conditions? If the bill of lading is not clearly declared the goods and defective clause or notation, packing condition is cleaning; On board date on the bill of lading already is content.

QWhat does AWG mean?ASimply stated, AWG or American wire gauge is the standard system that determines a cross section of a wire using a gauge for solid, round electrical wires. The higher the AWG number, the thinner or smaller the wire. Used since 1857, AWG has helped users determine a wire’s current-carrying ratings. AWG is determined by figuring out the radius of the wire squared, times pi. Most often, we use the term “circular mil,” which is the area of a 1/1000 or 1 mil diameter circle. These measurements are made on the wire alone; no jacketing or insulation factors into AWG size. AWG relates also to resistance; so a thicker wire has less resistance and thus can carry more voltage a longer distance. When stranding conductors, it is common to use smaller gauge sizes with higher AWG numbers, as they are more flexible and durable during applications that experience bending and vibrations. And although you can tightly braid or wind wires, there will always be a small gap between each strand, so stranded AWG wires are always slighter bigger in diameter than their solid wire counterparts. AWG tables are only for single, round conductors. A conversion table is required for stranded conductors. Most cable providers provide AWG data on their spec sheets.

QHow many types of flexible cable are there?AAccording to Tano Cable products classify, there are four common types of flexible cable. These include rolling flexible cable, bending flexible cable or "tic-toc," torsional flexible cable and variable/random motion flexible cable. Variable flexible cable include rubber cable and welding cable.

QDo flexible cables meet industry standards?ATano Cable Flexible Cable meet various standards. Flexible Cable may be UL Listed, CSA certified, CE marked and/or meet military specifications. However, every flexible cable is different, so make sure to specify if your flexible cable needs one or more standards to be met.
