Each cable and the outside of each reel or coil, shall be plainly marked or tagged to indicate the cable length, voltage rating, conductor size, and manufacturers lot number and reel

22、 number. Each coil or reel of cable shall contain only one continuous cable without splices. Cables for exclusively dc applications, as specified in paragraph HIGH VOLTAGE TEST SOURCE, shall be identified as such. Shielded cables rated 2,001 volts and above shall be reeled and marked in accordance w

23、ith Section I of AEIC C8 or AEIC CS8, as applicable. Reels shall remain the property of the Contractor Government.1.4 PROJECT/SITE CONDITIONS*NOTE: Use this paragraph to describe unusual environments, such as temperature extremes, chemical exposure, etc.*_PART 2 PRODUCTS2.1 MATERIALS*NOTE: Variation

24、s from these specifications may be appropriate in some cases. In addition to increasing rated circuit voltage where large overvoltages could occur, material sizes and strengths should be coordinated to withstand any pulling forces which will be applied. The lower strength of EPR, even jacketed, may

25、at times preclude the use of this material for long pulls. If variations are requested by a Contractor, they should only be approved if the safety and integrity of conservatively designed circuits are not compromised. The use of polyvinyl chloride (PVC) insulation or jacket material will not be perm

26、itted.*2.1.1 Wire Table*NOTE: An example typical wire table and a Format Template for a Wire Table are located at the end of this Section. Use this paragraph and Format Template, if itemized characteristics for each application are to be tabulated.*Furnish wire and cable in accordance with the requi

27、rements of the wire table below appended to these specifications, conforming to the detailed requirements specified herein.SECTION 26 05 19.00 10 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-2.1.2 Rated Circuit VoltagesAll wire and cable sha

28、ll have minimum rated circuit voltages in accordance with NEMA WC 70.2.1.3 Conductors*NOTE: All cable assemblies (multiple-conductor and single-conductor) must pass, or be capable of passing, the Institute of Electrical and Electronics Engineers (IEEE) 383 flame test, paragraph 2.5, using the ribbon

29、 gas burner. Single conductors and individual conductors of multiple-conductor cables shall also be required to pass the flame test described in NEMA WC 70. (This requirement was previously restricted to cable tray applications. It is extended to all uses for greater safety, since flame-resistant ca

30、bles are now available from many manufacturers.)*2.1.3.1 Material for Conductors*NOTE: If aluminum is to be specified for any of the wire purchased, revise this paragraph accordingly.Conductors for wire and cable rated 2,000 volts or less shall be copper. For wire and cable rated 2,001 volts and abo

31、ve, the specifications may be written to permit either aluminum or copper conductors where aluminum is suitable for the application and is determined to be more economical than copper.Aluminum conductors should be permitted only where cost comparisons show an overall savings and after a careful eval

32、uation of the corrosion problems associated with their use. They should only be allowed where installers are qualified to make reliable connections with them. Costs should be compared between all pertinent items such as installation, conduit, tray, tunnel and duct banks, lifetime costs of energy los

33、ses if significant, and differences in ventilation needs if losses are evaluated. Conductors should have the required current carrying capacities, the required short circuit capacities, and should be satisfactory with respect to voltage drop. Aluminum conductors should be sized to have equal or less

34、 resistance than the alternate copper conductors unless the total cost comparison, including losses, shows a net advantage otherwise. In such cases where the engineering costs to properly compare the use of the two materials will exceed any possible savings to be achieved by aluminum, the arbitrary

35、choice of copper may be the best policy.*SECTION 26 05 19.00 10 Page 8Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Conductors shall conform to all the applicable requirements of NEMA WC 70, as applicable, and shall be annealed copper. Copper condu

37、No. 16 AWG for annunciator circuits; and No. 19 AWG for alarm circuits. Minimum wire sizes for rated circuit voltages of 2,001 volts and above shall not be less than those listed for the applicable voltage in NEMA WC 70, as applicable.2.1.3.3 StrandingConductor stranding classes cited herein shall b

38、e as defined in NEMA WC 70, as applicable. Lighting conductors No. 10 AWG and smaller shall be solid or have Class B stranding. Any conductors used between stationary and moving devices, such as hinged doors or panels, shall have Class H or K stranding. All other conductors shall have Class B or C s

39、tranding, except that conductors shown on the drawings, or in the schedule, as No. 12 AWG may be 19 strands of No. 25 AWG, and conductors shown as No. 10 AWG may be 19 strands of No. 22 AWG.2.1.3.4 Conductor ShieldingUse conductor shielding conforming to NEMA WC 70, as applicable, on power cables ha

40、ving a rated circuit voltage above 2,000 volts. In addition, conductor shielding for shielded cables shall also comply with Section C of AEIC C8 or AEIC CS8. Strict precautions shall be taken after application of the conductor shielding to prevent the inclusion of voids or contamination between the

41、conductor shielding and the subsequently applied insulation.2.1.3.5 Separator TapeWhere conductor shielding, strand filling, or other special conductor treatment is not required, a separator tape between conductor and insulation is permitted.2.1.4 Insulation2.1.4.1 Insulation Material*NOTE: The insu

42、lation compounds specified herein are of the thermosetting type. Two options are included: cross-linked thermosetting polyethylene (XLPE), in accordance with the National Electrical Manufacturers Association (NEMA) publication WC 7 (Insulated Cable Engineers Association (ICEA) publication S-66-524),

43、 or ethylene-propylene rubber (EPR), in accordance with NEMA WC 70 (ICEA S-68-516). These two materials alone are widely available and can be satisfactorily compounded to meet the requirements of a conservative cable design for long and reliable service.
