No movement of the 2 inch Otherwise, the steel strip except stainless shall be zinc-coated. Loosening or detachment during the adherence test of superficial, small particles of zinc formed by mechanical polishing of the surface of zinc-coated wire shall not constitute failure. When used, a tape shall be applied helically and overlapped not less icez 10 percent of its width.

Table lists ieca which are conducted according to other standards. When an insulated conductor is individually covered with a non-metallic jacket, the insulation resistance shall not be less than 60 percent of that required for the insulation based on the thickness of the insulation.

If the direction of lay is not reversed in a cable containing layers of conductors, the outer layer of conductors shall have a left-hand lay and the direction of lay of the conductors in the inner layers shall be governed by the cabling machine.

The conductor shall be removed from a short length of wire by slitting the coverings. Galvanized steel wire armor. Applies to materials, constructions, and testing of volts and less thermoplastic, crosslinked polyethylene, and crosslinked rubber insulated wires and cables which are used for the transmission and distribution of electrical energy for normal conditions of installation and service, either indoors, outdoors, aerial, underground, or submarine.

The fault indicator shall be connected to indicate abnormal current between electrode and ground. The maximum length of lay shall jcea 60 times the diameter of the largest insulated conductor.

The test voltages shall be based on the rated voltage of the cable and the size of the conductor and not on the apparent thickness of the insulation. A volume resistivity of The conductor s in the cable shall be tested to assure continuity when grounded at one or both ends. The test specimens shall be molded from material taken from the completed cable. For any nominal width of metal tape used, the width tolerance ices be 0.

The messenger shall be laid parallel to the axis of a single conductor or the assembled conductors. The test method for the particular jacket material shall be based on Table below. Where the outer layer of an uncoated stranded copper conductor is tin coated, the direct current resistance of the resulting conductor shall not exceed icda value specified for an uncoated conductor of the same size.

Their use is recommended also for resonant grounded systems. If planing is employed, strips of the combined materials shall be cut from the conductor so that acceptable specimens can be prepared from these strips in such a manner that material from only one layer is present in the region between the gauge marks. Only one test unaged set or hot creep need be performed.

This applies either to a straight test piece or to one stamped out with a die, and it assumes corrugations have jcea removed.

Power Cables Rated 2,000 V or Less for the Distribution of Electrical Energy

Material Supplier’s certification shall be acceptable in lieu of the procedures above. When the direction of lay is reversed, the beginning and end of area reversal shall be defined on either side by the last convolution that does not exceed the maximum lay requirement on either side of the reversed area. Multiply the phase to phase system voltage by 1. Please first verify your email before subscribing to alerts. Method of bonding and grounding of sheaths. A jacket is considered sunlight resistant if after hours exposure the tensile and elongation properties retain a minimum of 80 Percent of their original values.

Division III See 4. Die-cut specimens shall be smoothed before being subjected to the aging tests wherever the thickness of the specimen is 90 mils 2. The sample shall be straightened immediately upon removal from the desiccator and inspected for surface cracks. Alternate Stability Factor, Difference days, max. For multiple conductor cables with individual conductors having a metallic sheath or armor over the cable assembly, the test voltage shall be applied between each insulated conductor and all other conductors and ground.

The jacket shall meet the requirements stated therein and those given in Table and In a cable in which the direction of lay is reversed: It is required for direct burial cable. For cables or conditions of service where mechanical stresses govern, such as in submarine cables or long vertical risers, the small conductor sizes may not be strong enough.

Power Cables Rated 2, V or Less for the Distribution of Electrical Energy – NEMA

Column B thicknesses apply to multi-conductor cables with an outer covering and to single-conductor cables with an outer covering. Metal tapes shall be a nonmagnetic material such as copper, copper alloy, or aluminum.

The zinc-coated tape shall not be more than 20 percent thicker than the stripped bare metal tape thickness. The cable shall withstand, without failure, the test voltages given in Table throughas applicable. Multiple grounding of shields is desirable in order to improve the reliability and safety of the circuit.

You may delete a document from your Alert Profile at any time. The maximum space between the turns of the metal armor tapes shall not exceed 20 percent of the width of the tape or 0. Wire band servings in accordance with 4.
