SPECIFIC REQUIREMENTS 14 TOR HIGH TEMP:FATUR CABL7 15 2

SCOPE 18 i

This specification covers the furnishing of single and 20 multiple conductor high tempe rature cable rated at 200 C and 1,000 v as specified in the cable schedules, for use on a-c or 21 6-c power, and control, where the maximem a mbient tempe ra tu:e 23 will not exceed 138 C.

~The cables shall be suitable for use in 24 i

wet or dry locations, inde rs, in

trays, conduits, underground ducts.

Installation of the cables will be by others.

25 l

The material covered by this specification will be used 28

/

in a nuclear power plant.

}

2 S TAND ARDS 30 Ihe cables covered in this specification shall be manu-32 i

factured in accordance with all the latest applicable standards 33 j

of ASTM, IpCEA, and IEEE. 3.

WORKMANSHIP ANb MATERIALS 35 r

  1. l All workmanship and material shall be first-class, the 37 l

best of their respective kinds, and shall be in accordance with the most modern electrical and mechanical engineering practice.

38 4

QUANTITY REOUIRED 40 Ihe attached schedules of requirements give the sizes 42 and lengths of the cables required, as well as other design and l

engineering data.

The Purchaser is to have the privilege of un increasing or decreasing the quantity of any item of cable 'not more than 10 percent at the unit price before manufacture is u5 actually started.

5.

CONDUCTORS 47 l

All cable conductors shall be made from stranded,

tin, u9 l

or alloy coated annealed'cepper wires.

Ihe stranding shall be 50 j

concentric round standard class 3 or X as noted in the Schedule i

of Requirements which forms part of this specification.

51 I

1 1

I NSULATION 54 Ihe individual conductor insulation material shall 56 consist of a

silicone rubber with fibre glass fillers as 57 necessary to inprove its physical and electrical properties and to make it suitable f or operatien at high tempe ra ture s.

Ihe 60 l

MG(c LRet;%

(,

SV-317 insulation material shall be applied directly to the conductor and shall a dhere tightly to that surface.

I The insulation shall be resistant to heat, noisture, 62 radiatien7 flame, and fire, and shall be capable of retaining its 63 electrical properties under the environmental conditions stipulated in paragraph 11 of this specification.

t 1

The insulatien thickness shall be in accordance with the 65 l

applicable standards for the rated voltage and size indicated in (6 '

l the attached cable schedule.

l 7.

S HIELDING 68 f

Ehere stated in the Schedule of Requirements, which 70 T

forms part of this specification, the overall conductor shielding gaterial shall be copper backed mylar tape having a minimum of 71 0.25 tape width lap and shall have 100 percent coverage.

i A No.18 AWG solid copper drain wire shall be in contact 73 with the shield throughout the length of the cable.

74

~

t..\\4 q, 8.

CABLE ASSEMBLY 76 i

In multiconductor cables assembled from individual 78 insulated conductors, the insulation over each conductor shall be covered with a

glass braid.

The inter stices between the 80 insulated conductors shall be filled and rounded with a

fibre glass filler and shall be nonhygroscopic and flane resistant.

81 Silicone coated glass binding tape shall be applied over tne 82 cable assembly to hold together the insulated conductors and 83

~

fillers, and form a complete surf ace for the overall jacket.

e i

9.

CA3LE FINISH 85 l

4 A

finishing cover over the cable assembly shall be used 87 j

8 en all single-conductor and multiple-conductor cables.

It shall 88 j

consist of an asbestos braid with silicene varnish finish.

For 89

)

cables with jackets applied directly over the insulation,

[he 90 jacket material shall be compatible with the insulation so that l

neither she insulation nor jacket shall experience harmful 91 effects cf a

chemical, mech anical, or electrical nature due to 92 the contact between jacket and insulation.

i 10.

CAELE AND COUDCCTOR IDENTIFICATION 95 s-311 insulated conductors in each multicenductor cable 97 l

shall be marked in accordance with IPCIA Method 1 consisting of l

colcr coding f or conductor circui; identification.

Color coding 99 i

by painting shall not be acceptable.

!NTacDUCtrcN The Qualification Test Program described in this report was con-ducted to determine whether eight types of cable manufactured by the s

Cerro Vire and Cable Ce:pany would function properly under simulated post-accident reactor centain=ent environmental conditions. The program included subjecting cable samples to a steam and chemical spray environ-ment while the cables were electrically loaded. The performance of the insulation was also tested at various points during the program.

The sa:ples tested'are identified in Table 1.

2.

IRRADIATION Three 5-fict lengths of each cable sa:ple were e;c:ect to irradiation

\\

frc= a Ct-10 scuree. The speciruns were sdentiftec by a: Jing the i

des 1Enatien L1, L2 and L3 to each.f th4 Franklin "ns::tute numbers

  • A #
tven in Table 1; thu., the speci ens.f 3 ample 1 vere Ill. IL
and IL3.

The cables were scund arcund a dru= cf galvaniced sheet (10 in.

dia. x S-1/4 in. high), and placed inside an alu-inu ccntainer (12 in.

1 1.4. x 15 in high, appr:xiestely). A lid was sealed to the pot with KT'.' siliccne rubber te keep the centents dry during their exposure to pa==4 radiatien. The irradiation was perfor:ed in a water pool at f acilities* of the indust rial Feacter Laboratory (!KL). Cobalt-60 source pins were placed in a circular pattern inside the irradiater structure sh vn in Tigure 1 and the :entainer was suspended inside the attacture with the pins surreundtng s c.

To assure unifer=1ty of irradiation, the tentainer was rctat ed by a =ctor at the t.p and of the s uspendicg wire at a rate of ' rev hr.

Three specimens of each of eight types of electrical cable were subjected to total doses ranging between apprcrxiantely 50 to 200 Megarads of radiation f rom a Cobalt 40 sourcs. The same cables were then placed in a test chamber and subjected to steam and borated water spray for f,

an extended period. Subsequently, they were eunined and subjected i

to insulation tests. It can be concluded that the performance of ;ba -

cable will be acceptable for use under the conditions simulated in these tests without any loss of performance. '
