SYM. G SPECIFICATION FOR TWO -CONDUCTOR CROSS -LINKED POLYETHYLENE INSULATED CABLE 1 SCOPE This specification establishes the minimum requirements for two -conductor insulated, shielded, and jacketed concentric -neutral underground distribution cable, insulated with a thermosetting dielectric based on cross -linked polyethylene (XLP). Cable described herein is intended for 60 Hz, single and three-phase applications in wet or dry locations in conduit, underground duct systems, direct buried and aerial installations in open air in sunlight. 2 APPLICABLE DOCUMENTS The following documents of the issue shown form a part of this specification to the extent specified herein. In those cases when the document is not dated, the latest issue in effect on the date of invitation for bids shall form a part of this specification. 2.1 AEIC NO. CS-8-2000 (1" Edition) -Specifications for Extruded Dielectric, Shielded Power Cables Rated 5 through 46 kV, first edition. 2.2 ICEA PUB. NO. S-94-649-2000 -Standard for Concentric Neutral Cables Rated 5,000 — 46,000 Volts, 2.3 OTHER STANDARDS • Applicable ASTM standards • Applicable ANSI standards • Other applicable ICEA/NEMA standards 3 REQUIREMENTS 3.1 GENERAL REQUIREMENTS FOR DESIGN 3.1.1 Basic Design Standards Cables purchased under these specifications shall, unless otherwise specified, meet the requirements of AEIC No. CS8, applicable ANSI/ICEA Standards, and the modifications and additions given in the subsequent paragraphs. In case of conflict, the requirements of the following documents shall apply in the priority shown: 1) This specification. 2) AEIC No. CS8-2000 3) ANSI/ICEA S-94-649-2000 4) Other applicable ANSI, ICEA-NEMA and ASTM Standards. 3.1.2 Temperature Ratings The following maximum temperature ratings shall apply: Operating (Continuous) Emergency Overload Short Circuit 90°C (194°F) 130°C (266°F) 250°C (482°F) 3.1.3 General Construction Cable covered by this specification consists of a blocked strand central conductor, conducting strand shielding layer, TRXLPE insulation, semi -conducting XLPE insulation shield, concentric neutral applied helically overall, and an overall insulating thermoplastic jacket. The conductor shield, insulation, and insulation shield shall be applied to the conductor through a single crosshead in one manufacturing pass; i.e., true triple extrusion is required. The insulation compound shall be extra clean and transported and stored in contamination free bulk handling systems. 7 367-102
