18、35-2000, IEEE Guide for the Properties of Identifiable Jackets for Under-ground Power Cables and Ducts.)This guide is concerned with the identification of a jacket as it is defined in The IEEE Standard Dictionary ofElectrical and Electronic Terms, Sixth Edition (“A thermoplastic or thermosetting pla

19、stic covering, some-times fabric reinforced, applied over the insulation, core, metallic sheath, or armor of a cable”). Users shouldnote that this guide makes reference to standards developed by the Insulated Cable Engineers Association(ICEA), and other organizations.This guide is written for the ma

The purpose of the guide is to present methods for defining and selecting red stripes orraised ridges used in conjunction with underground power cable and duct. Other methods of power cable andduct identificatio

30、reserved.1IEEE Guide for the Properties of Identifiable Jackets for Underground Power Cables and Ducts1. OverviewMany methods have been used to identify underground power cables and ducts. They range from markertapes, raised ridges, indent printing, and colored or striped jackets. In 1993, the Natio

31、nal Electrical SafetyCode(NESC) adopted rule 350G, which applies to all direct buried jacketed supply cable meeting rule350B and all direct buried communication cables. NESCrule 350G stipulates a lightning bolt be indentedor embossed in the outermost cable jacket of supply cable or duct at a repeati

32、ng frequency of not more than1 meter (40 inches). The symbol may be sequentially combined with other data or symbols, or both, printedon the jacket, but shall be separated as indicated in Figure 350-1 of the NESC. Some utilities are usingadditional identification, such as red stripes or raised ridge

33、s, to supplement the NESCrequirement.It is left to the utilitys discretion to determine the appropriate type of cable identification, as well as whatsize and type installation merits being identified. Since the red stripes and raised ridges are extruded (or co-extruded) with the outer protective jac

34、ket material, it is the intent of this guide to ensure that the red stripematerials be fully compatible and firmly bonded to the overall outer protective jackets or ducts. The redstripes should not discolor significantly during limited outdoor storage of cable reels at cable manufacturersand utiliti

35、es, or when buried underground. This guide recommends 1000 hours Xenon-Arc aging to demon-strate acceptable outdoor exposure, and 672 hours aging at 60 C in tap water, 5% hydrochloric acid (HCL)solution, and 5% sodium hydroxide (NaOH) to demonstrate acceptable color stability when buried.1.1 ScopeTh

36、is guide provides recommendations for red stripe and raised ridge identification markings on insulatingand semiconducting linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), highdensity polyethylene (HDPE) and polyvinyl chloride (PVC) jacketed underground power cables, and H

37、DPEduct containing jacketed or unjacketed underground power cables. The red stripe recommendations includethe number of stripes, color, width, thickness, retention characteristics, physical properties, storage criteria,and testing methods. The raised ridge recommendations include physical properties

38、, width, height, andcircumferential spacing. It is the intent of this guide to provide a minimum level of physical, chemical, andcolor durability on red stripes used to identify underground power cables and ducts.IEEEStd 1235-2000 IEEE GUIDE FOR THE PROPERTIES OF IDENTIFIABLE2Copyright 2000 IEEE. Al

39、l rights reserved.1.2 PurposeJacketed underground power cables and their related duct systems are similar in size and appearance tocommunication cables and underground pipes. Identification and differentiation of underground powercables and ducts has been attempted by marker tapes, raised ridges, in

40、dent printing, colors (other thanblack), and striped jackets. In the absence of a standard or guide on the properties of red stripes used as iden-tification markings, some utilities have reported that red stripes whiten after limited (in some cases, less thanone year) outdoor storage. This guide pro

41、vides recommendations for the properties, design, dimensionalrequirements, and testing of red stripes used as identification markings on underground power cables andducts. In addition, this guide provides physical attribute recommendations for raised ridge identification.2. ReferencesThis guide shal
