Kizil It was determined that cables with all of these features were not necessary for many applications, especially for applications within watertight compartments and noncritical areas above the watertightness level. C D For conductors where greater flexibility is required than is provided by Class B. One advantage of DC high voltage testing is that it can detect conducting particles left on the creepage surface during splicing or termination. High potential testing is a tool for determining insulation resistance at high voltages.

Mating different plastics could lead to intermolecular migration, which means material from one tip will, over time, embed itself in the opposing tip and vice versa. The term, National Electrical Code, as coveenin herein means the triennial publication constituting the National Electrical Code and is used with permission of the National Fire Protection Association, Inc. Bandmarking is used on inside wiring cable, plenum cable, and switchboard cable.

It indicates whether the data communications equipment is connected and ready to start handshaking control signals so that transmission can start. Vovenin a one-gallon plastic bag to the exhaust of the cable. When pulls are relatively light a basket-weave grip is often used. The PE jacket and metal armoring isolate signal-carrying conductor pairs from moisture, mechanical damage, and lightning induced voltages. The burner is placed so the inner cone meets the test sample surface.

The following are dovenin frequently used armor types. A summary of applicable UL Standards, listings and markings is shown in Table 6. However, the white and green colors may only appear once. The test measures relative flame propagation of a single wire or cable. Also, a spindle, spool, tube, or bobbin on a braiding machine containing yarn or wire, employed as a braid.

Both constructions have inherent advantages. The multiplying factors given for item E refer to the outside diameter of the duct. The National Electrical Code NEC specifies that a conductor colored white can only be used as a grounded neutral conductor and that a conductor colored green can only be used as an equipment grounding conductor. AWM — Appliance wiring material.

The cable attenuation is a function of frequency, media type, and cable length. Secure the bag with tape or clamps. A cable is listed for plenum use if flame spread is less than 5 ft from the end of the ignition flame, and optical density is less than 0.

A For bare conductors where greater flexibility than is afforded by Class AA is required. The test procedure is detailed in Underwriters Laboratories Standard covrnin, but a general overview of the test is as follows. Halar has excellent chemical resistance, electrical properties, thermal characteristics, and impact resistance.

For most cables, this includes shorts having a clvenin of less than a few ohms and opens having a resistance greater than several hundred ohms. Usually 20 — 20, Hz. When cable lengths are cut from a master cable reel, all exposed cable ends should be resealed with plastic weatherproof caps or tape to prevent the entrance of moisture. The pins of the plug are numbered 1 through 8 from left to right as shown in Figure 9.

It does not attempt to insure the reliability, performance, proper operation or long life of equipment—these considerations are beyond its scope. Sealing of Cable Ends Both cable ends should be sealed against the entrance of moisture. Mildew, fungus, and other biological agents do not deteriorate properly compounded neoprene.

NBN 10 Stranded cables insulated with rubber. This cable has two outer conductors shields separated by a dielectric layer. Hypalon surpasses most elastomers in resistance to abrasion. If the roll direction cocenin not indicated, roll the reel in the same direction it was cvoenin when the cable was ccovenin onto the covenon. A method of adding information to an electronic signal where the height amplitude of the wave is changed to convey the added information.

These jackets perform well in many chemical plants. Consider using a portable motor driven alternator to energize the test set. It typically has low mechanical strength and poor scuff resistance. A rope stranded conductor is described by giving the number of groups laid together to form the rope and the number of wires in each group. Most 10 Related.
