1. UVOD 

ELKA je osnovana 1927. godine i danas je u Republici 

Hrvatskoj jedini proizvo|a~ energetskih distribucijskih kabela 

napona 1 kV do 36 kV. Elka je i proizvo|a~ XLPE i 

elastomernih izolacijskih smjesa za izolacije niskonaponskih i 

srednjenaponskih energetskih kabela s vi{e od 20 godina 

iskustva na razli~itim proizvodima i komercijalnom plasmanu. 

Srednjenaponski kabeli s XLPE izolacijom proizvode se 

najsuvremenijom tehnologijom izoliranja u trostrukom 

brizganju istovremenim nano{enjem poluvodljivih slojeva na 

izolaciju (triplex extrusion). 

Umreènje izolacije je suhim postupkom (dry cured 

vulcanisation) u neutralnom plinu du{iku. Ovim postupcima 

dobiva se kvalitetan i ~vrst spoj izme|u izolacije i vodljivih 

slojeva bez mogu}nosti odvajanja pri ciklusima grijanja i 

hla|enja kabela u radu. Umreènjem u du{iku pove}ana je 

otpornost izolacije na nastajanje i {irenje "treeinga" a time i 

pojava parcijalnog izbijanja, {to zna~ajno podiè stupanj 

dielektri~ke ~vrsto}e izolacije i produàva ìvotni vijek kabela. 

Elka posjeduje vlastiti razvojni centar i ispitne laboratorije za 

materijale i kabele sa suvremenom opremom i visoko stru~nim 

osobljem {to garantira visoku kvalitetu finalnih proizvoda, 

materijala i kabela. 

Sustav osiguranja kvalitete (Quality Management System) 

potvr|en je Certifikatom ISO 9001 izdanim 1997. godine, a 

Sustav upravljanja okolišem certifikatom ISO 14001 izdanim 

2002. godine od tvrtke SGS International Certification Services 

AG, [vicarska.

1. INTRODUCTION 

ELKA was founded in 1927 and is currently the only producer 

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

Republic of Croatia. ELKA produces also XLPE and elastomere 

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 manufactured 

with most recent technology of insulation in triple extrusion 

under simultaneous application of semi-conductive layers 

over insulation (triplex extrusion). 

Cross-linking of insulation is done by dry cured vulcanisation 

procedure 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 laboratories 

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 2002 by the 

firm SGS International Certification Services AG, Switzerland.

6. STRUJNA OPTERE]ENJA 

6.1. STRUJNO OPTERE]ENJE KABELA 

Elektri~na struja protjecanjem kroz vodi~e kabela razvija 

toplinu {to uzrokuje isu{enje okolnog zemlji{ta te dovodi do 

mogu}eg toplinskog kolapsa kabela. S tog razloga potrebno je 

ograni~iti veli~inu struje protjecanu kabelom ovisno o uvjetima 

pogona u kojem kabel radi. Dopu{teno strujno optere}enje 

kabela izra~unato je prema IEC 287 pri ~emu je uvaèno 

slijede}e: 

0 

•temperatura zemlje 20 C 

0 

•temperatura zraka 30 C 

0 

•temperatura vodi~a 90 C 

•specifi~ni toplinski otpor zemlje 1,0 K x m/W 

•specifi~ni toplinski otpor XLPE 3,5 K x m/W 

•specifi~ni toplinski otpor PVC 6,0 K x m/W 

•specifi~ni toplinski otpor PE 3,5 K x m/W 

•dubina polaganja u zemlju 0,7m 

•razmak kabela u zemlji 0,07m 

•razmak kabela u zraku promjer kabela

6. CURRENT RATINGS 

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. to IEC 287, considering the 

following data: 

•ground temperature 20ºC 

•air temperature 30ºC 

•max. conductor temperature 90ºC 

•specific resistance of ground 1,0 K x m/W 

•specific thermal resistance of XLPE 3,5 K x m/W 

•specific thermal resistance of PVC 6,0 K x m/W 

•specific thermal resistance of PE 3,5 K x m/W 

•ground laying depth 0,7 m 

•cable spacing in ground 0,07 m 

•cable spacing in air cable diameter

10. POLAGANJE I SPAJANJE KABELA 

10.1. OP]ENITO O POLAGANJU 

Polaganje kabela mora biti pa`ljivo da ne do|e do o{te}enja 

kabela ni za vrijeme polaganja niti kasnije u pogonskom radu. S 

tog razloga preporu~uje se pridràvati slijede}eg: 

•Polagati kod temperature koja ne}e uzrokovati o{te}enje 

kabela ni ugroziti sigurnost ljudi i opreme 

•Razvla~enje kabela izvoditi ure|ajem za razvla~enje s 

kontrolom vu~ne sile 

•Kabel kod polaganja u zemlju polagati uvijek na pripremljenu 

posteljicu; ne smije se vu}i po zemlji, pogotovo ne po kamenitom 

tlu 

•Materijali za posteljicu ne smiju imati agresivni utjecaj na pla{t 

kabela 

•Kabel ne savijati ispod najmanjeg dozvoljenog polumjera 

savijanja 

•Kabelski rov ne zatrpavati grubim kamenjem 

•Iznad kabela postaviti {titnike i upozoravaju}u vrpcu 

•Krajeve kabela obavezno zatvoriti vodonepropusnim kapama 

10.2. TEMPERATURA POLAGANJA 

Kabeli s PVC pla{tom mogu se polagati na temperaturi okoline 

0 

do -5 C, dok se kabeli s PE pla{tom mogu polagati i kod tem- 

0 

peratura do -20 C. 

Za polaganje kod temperatura niìh od navedenih potrebno je 

0 

provesti zagrijavanje kabela na temperaturu iznad +5 C, jednom 

od za to poznatih metoda i odràvati tu temperaturu najmanje 

24 sata prije polaganja. 

10.3. POLUMJER SAVIJANJA 

Kod polaganja potrebno je pridràvati se slijede}ih vrijednosti: 

•tijekom polaganja 

jednoìlni kabel Rs≥15D 

troìlni kabel Rs≥12D 

•kabel poloèn, savijen preko forme 

jednoìlni Rs≥12D 

troìlni Rs≥9D 

gdje je: 

D - vanjski promjer kabela /mm/ 

10.4. SILA RAZVLAÊNJA 

Dopu{tena sila razvla~enja kabela ne smije prije}i kod

10. LAYING AND CONNECTING OF CABLES 

10.1. GENERALLY ON LAYING 

Cables are to be laid carefully, to avoid cable damage either 

during laying or later in operating conditions. Because of that, 

one should respect the following: 

•Cables 

are to be laid at the temperature which won't cause 

cable damage nor endanger the safety of people or equipment 

•Cable 

stretching should be performed by a stretching device 

equipped by tensile strength control 

•When 

laid into the ground, the cable is always to be laid at 

prepared bedding; it must not be pulled over the ground, 

specially not over stony terrain 

•Bedding 

material shouldn't act aggressively upon cable sheath 

•Permitted 

bending radius to be respected. 

•Cable 

trench must not be covered up with rough stones 

•Protections 

and warning tapes should be put over the cables 

•Cable 

ends should be obligatorily closed by watertight caps. 

10.2. LAYING TEMPERATURE 

PVC sheathed cables could be laid at ambient temperature up 

to -5ºC, whereupon the PE sheathed cables could be laid even 

at -20ºC temperature. 

When laying at lower temperatures than those stated, cables 

should be warmed up to the temperature of over +5ºC 

applying one of the adequate known methods and that 

temperature is to be maintained for at least 24 hours before 

laying. 

10.3. BENDING RADIUS 

The following values are to be respected at laying: 

•during 

laying 

single-core cable Rs≥15D three-core cable Rs≥12D •laid 

cable, bended over the form 

single-core cable Rs≥12D three-core cable Rs≥9D where: 

D -outer cable diameter /mm/ 

10.4. TRACTIVE FORCE 

Permitted tractive force of a cable must not exceed at 

2 

•cable stocking application Pd≤ 5 D kN 

•cable 

grip application 

Conductor Cu Pd≤n x q x 50 kN 

Conductor Al Pd≤n x q x 30 kN 

where: 

D -cable diameter (mm) 

n -number of conductors in cable (or number of cables) 

2 

q -conductor cross-section (mm ) 



Preporu~a se razvla~enje kabela vu~nom ~arapicom. Dio kabela 

obuhva}en vu~nom ~arapicom nakon zavr{enog razvla~enja 

obavezno odsje}i. 

10.5. SPAJANJE I ZAVR[AVANJE KABELA 

Najpoznatiji na~ini spajanja i zavr{avanja srednjenaponskih 

kabela s XLPE izolacijom su: 

•primjena predoblikovanih spojnica i kabelskih zavr{etaka 

•omatanje vrpcama posebno izra|enim za ove namjene 

Potrebno je po{tivati upute proizvo|a~a kod izvedbe spojnica i 

kabelskih zavr{etaka. 

Elka, na zahtjev, uz isporuku kabela osigurava i: 

•isporuku spojnica i kabelskih zavr{etaka za sve tipove kabela iz 

svog proizvodnog programa, 

•montaù spojnica i kabelskih zavr{etaka,

It is recommended to pull the cables by using a cable stocking. 

The part of the cable covered by the cable stocking should be 

obligatorily cut off after completed traction. 

10.5 CONNECTING AND TERMINATING OF CABLES 

The best known ways of connecting and terminating of medium 

voltage cables with XLPE insulation are: 

•application 

of prefabricated junctions and cable terminations 

•wrapping 

by specially designed tapes 

Producer's instructions are to be respected at junction and cable 

termination execution. 

At request, along with the cable delivery, ELKA can secure: 

•delivery of junctions and cable terminations for all cable typ- 

es of its production program 

•assembly 

of junctions and cable terminations
