Maximum phase to phase operating voltage. The conductor shield shall be easily removable from the conductor and the outer surface of the extmded shield shall be firmly bonded to the overlying insulation. Specimens shall break between the gauge marks to be a valid test. The temperature profile, as required in Gauge marks shall be 2 inches The cable shall be unwound and the bend repeated in the opposite direction.

Approximate diameters of individual wires in stranded conductos. Plan C One test for each 50, feet 15, m of cable or at least once per cable core extruder run. Overload temperatures are to OCfor cables rated up to and including kV and OCfor cables rated abwe kV.

The conduit diameter shall be such that when the cabie is lying on the bottom of the conduit, there shall be a clearance of approximately 2 inches 51 mm iea the top of the cable and the inner surface of the conduit. Ten impulses of each polarity with magnitude equal to the BIL shown in Table shall be applied. The jacket is not sunlight resistant if an 80 percent or greater 10 for either the tensile or elongation after the hours of exposure is not maintained.

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

ASTM B 5 d electrical grade copper. The jacket material tests or certificationfrom the material supplier can be used by all cable producers who propose to use the material. The minimum thickness of the corrugated tape shield before corrugation shall be 0. The first is Cable Qualification.


Unfilled insulations shall be examined using transmitied light. All ac tests shall be conducted at room temperature and at power frequency Hz. The value of K weight increment factor given in Table The sample shall be kept clean and shall be handled carefully to prevent surface damage and contamination. Traditional insulation thicknesses are listed in appendix F. At least the following propetties are to be considered when selecting the material of the conductor. ISCOPE This standard applies to materials, constructions, and testing of crosslinked polyethylene XLPE and ethylene propylene rubber EPR insulated single conductor shielded power cables rated above 46 to kV used for the transmission of electrical energy.

When a high degree of accuracy is not required, this test may be made with only two electrodes spaced at least 2 inches The metal shieldsheathshall be electrically continuous and free of burrs throughout each cable length. When requested the manufacturer shall demonstrate the effectiveness of the radial moisture bamer. To insure that the thermal insulation and the plastic pipe yield a similar temperature gradient, it may be necessary to set up a “dummy” length of cable using a pipe and thermal insulation material to compare the thermal characteristics of each.

This procedure is used on cable wafers with the conductor, jacket and metallic shield removed. Electrical Tests include a Hot Impulse Test Number of loaded cables in direct buried cable chase, duct bank or conduit system. The second is Jacket Material Qualification.

Each length of cable to be tested shall be sealed at one end over the insulation shield using a rubber cap filled with anhydrous calcium sulphate granules. It is not intended to be a comprehensive listing.

Method of cable identification. The wafer may be further separated into concentric rings by careful separation of the shield from the insulation. Wafers shall be approximately 25 mils 0.


Tests on the identical maten’als or design are not necessary to demonstrate the desired performance results. A dc or 60 Hz ac source can be used. The diameter shall not differ from the nominal values shown in Table by more than f 2 percent. When there are questions regarding compliance to this standard, measurements shall be made with an optical measuring device or with calipers with a resolution of 0.

The manufacturer shall wait a minimum of 20 days after the insulation extrusion process before the tests are performed. As soon as possible after the procedure. If thermai insulation material is used, it shall have a uniform thermal resistance along the cable length.

The manufacturer shall determine the alloy unless otherwise agreed upon between the manufacturer and the purchaser. In the case of complete change in color of all granules, the water shall be expelled from the conductor per 9.

The tensile strength and elongation of the specimens shall then be determined in accordance with 9. It is intended that the product furnished under this standard shall consistently comply with all of the qualification test requirements. If both such second samples pass the test, the lot of cable except the length represented by the first sampleshall be considered as meeting the requirements of this standard. Calculated diameter under metallic shielding: ASTM B for 19 wire combination unilay-stranded copper conductors.

By agreement between the manufacturer and the purchaser, an ac voltage at a frequency between 20 Hz and Hz, in accordance with one of the following may be used: This provides the tensile and elongation ratios for the jacket.
