This procedure shall be repeated after placing new granules in the cap. Tests defined in Part 9 of this standard with specific test frequency.
If the color has not completely changed to pink after 15 minutes, it is an indication that a tolerable amount of moisture is present in the strands. Additional qualification tests in The cable manufacturer should be consulted for verification of the emergency operating temperature of a given cable design.
Size of conductors in circular mils. Traditional insulation thicknesses are listed in appendix F. Moisture Migration Moisture penetration is a major conbibutor to the deterioration of cable insulation. The cotangent of the dielectric phase angle of a dielectric material or the tangent of the dielectric loss angle. Unfilled insulations shall be examined using transmitied light.
This infonation maybe in the form of a drawing. The minimum radius specified refers to the inner radius of the cable bend and not to the axis of the cable. This does not include douds, swirls or flow patterns which are normally associatedwith the extnrsion process.
All ac tests shall be conducted at room temperature and at power frequency Hz.

The separator tape, if present, shall not be included as part of the jacket thickness. The waveform shall be substantially sinusoidal.
In the case of complete change in color of all granules, the water shall be expelled from the conductor per 9. This applies either to a straight test piece or to one stamped out with a die and assumes that corrugations have been removed.
The resultant polymers may provide improvements while complying with applicable requirements in ICEA standards. In extreme cases, it may be necessary to use a segmental spechen. When tested in accordance with Part 9, the jacket shall meet the applicable requirements. Specimens shall be placed in the jaws of the testing machine with iceea maximum distance between jaws of 4 inches The stress limits are based on rated voltage, given in Table The current could be due to a normal load, emergency load or from a short-circuit condition.
The metal shieldsheath shall be applied in such a manner that electrical continuity or contiguity will not be distorted or disrupted during normal installation bending. Descriptions other than the foregoing.
Jacket thickness shall be as stated in 7. The thickness of the aluminum sheath shall be at least 0. The insulation shall meet ice following requirements: The resuiting wafer shall be at least 25 mils 0. Emergency conductor maximum operation temperature the cable was designed to meet. The generic metallic shield, sheath or jacket types are specified in Table The number of voids larger than 1 mils 0.
A cable design capable of withstanding electrical discharge in the insulation system at normal operating voltage. Existence of an ICEA standard does not in any respect preclude the manufacture or use of products not conforming to the standard.
It may or may not be cut into shorter lengths ica it is supplied to the end use customer. Jackets, though not typically designed for this, do filter out some of these ions as moisture migrates into the cable. The bedding layer shall be Semiconducting and meet the requirements of part 5. Other Factors The metallic shield designs mentioned icda often used in combination with each other.
Number of loaded cables in direct buried cable chase, duct bank or conduit system.
Wet or dry location. A semiconducting tape may be used between the conductor and the extruded shield in which case it shall not be considered as part of the extruded shield thickness.
A completed reel of cable shipped to the end use customer.
This procedure is used on cable wafers with the conductor, jacket and metallic shield removed. The results of this icsa. The insulation of the sample examined shall be free from: The insulated conductor shall have an insulation resistance not less than that corresponding to a constant K of 20, megohrns-1O00 ft at
