ICEA standards are adopted in the public interest and are designed to eliminate misunderstandings between the manufacturer and the purchaser and to assist the purchaser in selecting and obtaining the proper product for his particular need.
Existence of an ICEA standard does not icra any respect preclude the manufacture or use of products not conforming to the standard. The user of this Standards Publication 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.
Requests for interpretation of this Standard must be submitted in writing to the Insulated Cable Engineers Association, Inc. BoxCarrollton, Georgia An official written interpretation will be provided. Suggestions for improvements gained in the use of this Standard will be welcomed by the Association.
The members of the ICEA working group contributing to the writing of this Standard consisted of the following: Agglomerates and Contaminants as Applicable I Optional Center Strand Identification Type of Testing Machine I Winding of the Test Specimen on Mandrels ISCOPE This standard applies to materials, constructions, and testing of crosslinked polyethylene XLPE ocea ethylene propylene rubber EPR insulated single conductor shielded power cables rated above 46 to kV used for the transmission of electrical energy.
Parts 2 to 7 cover the major components of cables: Part 8 covers identification of cables. Part 9 covers production test procedures applicable to cable component materials and to completed cables. Part 1O covers qualification test procedures. Part 11 contains appendices of pertinent information. Units in these standards are generally expressed in the Imperial system. For information only, their approximate metric equivalents are included. To help avoid misunderstandings and possible misapplication of the cable, the purchaser should also furnish the following information: Desired ampacity for normal and emergency operation.
Nominal phase to phase operating voltage. Maximum phase to phase operating voltage. Symmetrical and asymmetrical fault current and duration for conductor and iea shieldlsheath. Installation method and geometry, for example: Direct buried in ground.
