1. INTRODUCTION

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).
Umre`enje 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. Umre`enjem u du{iku pove}ana je
otpornost izolacije na nastajanje i {irenje "treeinga" a time i
pojava parcijalnog izbijanja, {to zna~ajno podi`e stupanj
dielektri~ke ~vrsto}e izolacije i produ`ava `ivotni 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 okoliem certifikatom ISO 14001 izdanim
2002. godine od tvrtke SGS International Certification Services
AG, [vicarska.

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. CURRENT RATINGS

6.1. STRUJNO OPTERE]ENJE KABELA

6.1. CURRENT RATINGS OF CABLES

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 uva`eno
slijede}e:
temperatura zemlje 200C
temperatura zraka 300C
temperatura vodi~a 900C

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 20C
air temperature 30C
max. conductor temperature 90C

6.3. DOPUSTIVE STRUJE KRATKOG SPOJA

6.3. PERMITTED SHORT CIRCUIT CURRENTS

Otpornost izolacije na visoki toplinski u~inak struje kratkog

spoja odre|ena je grani~nom temperaturom vodi~a koja za
XLPE izolaciju iznosi 2500C.
Dopu{tena struja kratkog spoja faznog vodi~a kabela dodatno
je uvjetovana temperaturom vodi~a na po~etku kratkog spoja, u
pravilu 900C, i trajanjem kratkog spoja najvi{e 5 sekundi.
Dopu{tena struja kratkog spoja elektri~ne za{tite kabela
uvjetovana je temperaturom elektri~ne za{tite na po~etku
kratkog spoja, pretpostavljeno 700C, i najvi{om dozvoljenom
temperaturom bakrenih `ica ili vrpci elektri~ne za{tite,
pretpostavljeno 3500C, uz trajanje kratkog spoja najvi{e 5
sekundi.

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.

gdje je:
U0 - fazni napon (kV)
w - kru`na frekvencija (1/s)
C - kapacitet kabela (mF/km) prema Tablici 7.2.

It is determined by equation:
Ic=U0 x w x C x 10-3 A/km/phase

Impedancija kabela je kompleksna veli~ina i ovisi o otporu

vodi~a, induktivnom i kapacitivnom otporu kabela. Op}enito
mo`e se dati izrazom:
/Z/=R2+(wL)2 W/km
gdje je:
R - otpor vodi~a (W/km)
w - kru`na frekvencija (1/s)
L - induktivitet kabela (m H/km) prema tablici 7.3.

Cable impedance is a complex value depending on conductor

resistance, inductive and capacitive resistance of cable.
Generally, it could be expressed by equation:
/Z/=R2+(wL)2 W/km
where:

10. POLAGANJE I SPAJANJE KABELA

10. LAYING AND CONNECTING OF CABLES

10.1. OP]ENITO O POLAGANJU

10.1. GENERALLY ON LAYING

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 pridr`avati 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

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. TEMPERATURA POLAGANJA

10.2. LAYING TEMPERATURE

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

do -50C, dok se kabeli s PE pla{tom mogu polagati i kod temperatura do -200C.
Za polaganje kod temperatura ni`ih od navedenih potrebno je
provesti zagrijavanje kabela na temperaturu iznad +50C, jednom od za to poznatih metoda i odr`avati tu temperaturu najmanje 24 sata prije polaganja.

PVC sheathed cables could be laid at ambient temperature up

to -5C, whereupon the PE sheathed cables could be laid even
at -20C temperature.
When laying at lower temperatures than those stated, cables
should be warmed up to the temperature of over +5C
applying one of the adequate known methods and that
temperature is to be maintained for at least 24 hours before
laying.

10.3. POLUMJER SAVIJANJA

10.3. BENDING RADIUS

Kod polaganja potrebno je pridr`avati se slijede}ih vrijednosti:

tijekom polaganja
jedno`ilni kabel Rs1
5D
tro`ilni kabel Rs1
2D
kabel polo`en, savijen preko forme
jedno`ilni Rs1
2D
tro`ilni Rs9
D
gdje je:
D - vanjski promjer kabela /mm/

The following values are to be respected at laying:

during laying

single-core cable Rs15D

three-core cable Rs12D

laid cable, bended over the form

single-core cable Rs12D

three-core cable Rs9D

where:
D -outer cable diameter /mm/

10.4. SILA RAZVLA^ENJA

10.4. TRACTIVE FORCE

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

primjene vu~ne ~arapice
Pd 5 D2 kN
primjene vu~ne stezaljke
