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. A compound filled tape is a fabric cloth treated on one or both sides with a non-conducting compound. When the bedding is helically applied tape, yarn or roving, the direction of lay of the inner metal tape shall be opposite to that of the outer bedding layer. The jacket shall meet the requirements stated therein and those given in Table and

The weight of zinc coating shall be determined before application of the strip to the cable. Method of bonding ss-95-658 grounding of sheaths. Direct burial in trenches. If the required tensile safety factor is not maintained, the next larger size wire given in the table should be used. Unless otherwise specified, the jacket shall meet the applicable requirements specified in Table Air oven aging Oil immersion Heat distortion deformation 6.
Power Cables Rated 2, V or Less for the Distribution of Electrical Energy - NEMA
The effective ifea of rotation shall not exceed 60 rpm. The user of this Standard is cautioned to observe any health or safety regulations and rules relative to the manufacture and use of cable made in conformity with this Standard. The value of K weight increment factor given in Table For Flexible Aluminum Conductors s-95-65 manufacturer.
For example, a low voltage buzzer or light circuit or dc resistance method may be used.
The wire shall have a minimum weight of coating per square foot of uncoated wire surface in accordance with Table Consensus does not necessarily mean that there is unanimous agreement among every person participating in the development of this document. The tape s shall be free from burrs.
Multiply the phase to phase system voltage by 1. The ends of the sample shall be secured to the mandrel so that four complete turns of the sample will be exposed to the air between the securing means. During or prior to application, the tapes shall be flushed with a suitable compound to deter corrosion unless a supplementary corrosion protective covering is applied.
Where noted, one or more portions of Section 6 of this Standard provide specific instructions which may alter, clarify, or supersede portions of the referenced standard. The strip shall have an elongation of not less than 10 percent in 10 inches mm.
See Section 6 for method of measuring metal tape thickness. Use the resulting voltage value to select the corresponding insulation thickness from Tables,or as applicable. All tests shall be made prior to the application of the strip to the cable.
At least two specimens shall be tested. Each coil or reel selected and the sample taken from it shall be identified. Your Alert Profile lists the documents that will be monitored.
For cores having a diameter smaller than 0. Flexible conductors are referenced in 2. No movement of the 2 inch See Section 6 4. See Section 6 for method of measurement. The duration of the ac voltage test shall be 5 minutes.
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.
We have no amendments or corrections for this standard.
Power Cables Rated 2,000 V or Less for the Distribution of Electrical Energy
The diameter for the cross-section shall be the average of the four values. Some migration is known to occur.
Simultaneous aging of different compounds should be avoided. In common with other electrical equipment, the use of cables is not recommended on systems where the ratio of the zero to positive phase reactance of the system at the point of cable application lies between -1 and since excessively high voltages may be encountered in the case of ground faults.
