1. UVOD

ELKA je osnovana 1927. godine i danas je u RepubliciHrvatskoj jedini proizvo|a~ energetskih distribucijskih kabelanapona 1 kV do 36 kV. Elka je i proizvo|a~ XLPE ielastomernih izolacijskih smjesa za izolacije niskonaponskih isrednjenaponskih energetskih kabela s vi{e od 20 godinaiskustva na razli~itim proizvodima i komercijalnom plasmanu.Srednjenaponski kabeli s XLPE izolacijom proizvode senajsuvremenijom tehnologijom izoliranja u trostrukombrizganju istovremenim nano{enjem poluvodljivih slojeva naizolaciju (triplex extrusion).

Umreènje izolacije je suhim postupkom (dry curedvulcanisation) u neutralnom plinu du{iku. Ovim postupcimadobiva se kvalitetan i ~vrst spoj izme|u izolacije i vodljivihslojeva bez mogu}nosti odvajanja pri ciklusima grijanja ihla|enja kabela u radu. Umreènjem u du{iku pove}ana jeotpornost izolacije na nastajanje i {irenje "treeinga" a time ipojava parcijalnog izbijanja, {to zna~ajno podiè stupanjdielektri~ke ~vrsto}e izolacije i produàva ivotni vijek kabela.Elka posjeduje vlastiti razvojni centar i ispitne laboratorije zamaterijale i kabele sa suvremenom opremom i visoko stru~nimosobljem {to garantira visoku kvalitetu finalnih proizvoda,materijala i kabela.Sustav osiguranja kvalitete (Quality Management System)potvr|en je Certifikatom ISO 9001 izdanim 1997. godine, aSustav upravljanja okoliem certifikatom ISO 14001 izdanim

1. INTRODUCTION

ELKA was founded in 1927 and is currently the only producer

of distribution power cables of 1 kV to 36kV voltage in the

Republic of Croatia. ELKA produces also XLPE and elasto-

mere insulation compounds for insulation of low voltage and

medium voltage power cables, with more than 20 years of

experience in proper products and commercial sale.

Medium voltage cables with XLPE insulation are manufac-

tured with most recent technology of insulation in triple extru-

sion under simultaneous application of semi-conductive layers

over insulation (triplex extrusion).

Cross-linking of insulation is done by dry cured vulcanisationprocedure in a neutral nitrogen gas. By those procedures we

obtain a high quality and tight connection between insulation

and conductive layers without the possibility of their separation

during the heating and cooling cycles of cables in operation.

Cross-linking in nitrogen increases the resistance of insulation

towards appearance and spreading of "treeing" and thereby

also of partial discharge, increasing thus considerably the grade

of dielectric strength of insulation and prolonging the life-time

of cables.

ELKA has got a proper development centre and test labora-

tories for materials and cables with up to date equipment and

high qualified staff, what guarantees a high quality of final

products, materials and cables.

The Quality Management (Insurance) System is confirmed by

ISO 9001 Certificate, issued in 1997, and Environmental

Management by ISO 14001 Certificate, issued in 2002by the

firm SGS International Certification Services AG, Switzerland.

6.1. CURRENT RATINGS OF CABLES

The temperature developed by electric current streaming

through cable conductors, causing exsiccation of surrounding

ground, may be the reason of a possible thermal collapse of

cables. Because of that, it is necessary to limit the amount of

current streaming through the cable, in dependence on the

operating plant conditions of cable. Permitted current ratings

of cables is calculated acc. toIEC 287, considering the

following data:

ground temperature 20Cair temperature 30Cmax. conductor temperature 90C

6.3. DOPUSTIVE STRUJE KRATKOG SPOJA

Otpornost izolacije na visoki toplinski u~inak struje kratkogspoja odre|ena je grani~nom temperaturom vodi~a koja za

0XLPE izolaciju iznosi 250 C.Dopu{tena struja kratkog spoja faznog vodi~a kabela dodatnoje uvjetovana temperaturom vodi~a na po~etku kratkog spoja, u

0pravilu 90 C, i trajanjem kratkog spoja najvi{e 5 sekundi.Dopu{tena struja kratkog spoja elektri~ne za{tite kabelauvjetovana je temperaturom elektri~ne za{tite na po~etku

0kratkog spoja, pretpostavljeno 70 C, i najvi{om dozvoljenomtemperaturom bakrenih `ica ili vrpci elektri~ne za{tite,

0pretpostavljeno 350 C, uz trajanje kratkog spoja najvi{e 5sekundi.

6.3.1.Dopu{tena struja kratkog spoja za vodi~e kabela

Za vrijeme trajanja kratkog spoja razli~itog od vrijednostinavedenih u tablici, vrijednosti struje kratkog spoja za 1 sekun-du potrebno je pomno`iti s faktorom 1/t, gdje je t vrijeme tra-janja kratkog spoja u sekundama.

6.3. PERMITTED SHORT CIRCUIT CURRENTS

Insulation resistance to high thermal impact of short circuit

current is determined by a limit conductor temperature, which

amount to 250C for XLPE insulation.

Permitted short circuit current of cable phase conductor is

additionally conditioned by conductor temperature at the short

circuit beginning, regularly 90C and by short circuit duration,

but not more than 5 seconds.

Permitted short circuit current of cable electric protection is

conditioned by electric protection temperature at the short

circuit beginning, of anticipated value 70C, and the highest

permitted temperature of copper wires or tapes, electric

protection, anticipated 350C, and short circuit duration of

max. 5 seconds.

During short circuit duration differing from in the upper Table

stated values, the short circuit current values for 1 second are

to be multiplied by 1/t factor, where t denotes short circuit

duration in seconds.
