N2XSH cable combines a copper conductor, screened XLPE insulation and a low-smoke, halogen-free sheath for fixed medium-voltage distribution. It is relevant to industrial feeders, substation connections and building power routes where smoke and combustion-gas requirements influence the cable specification.
XWA Power & Cable manufactures power cables in China for international projects, with production to customer drawings and cable schedules. Contact us for an N2XSH project quotation.

N2XSH Cable for Industrial and Building Power Routes
The LSZH sheath addresses specified smoke and combustion-gas requirements alongside the electrical duty, making this construction relevant to enclosed industrial and building power routes.
- Industrijska distribucija: fixed feeders between substations, switchgear and plant power systems where screened MV cable and defined fire behaviour are required.
- Building supply: indoor cable routes with low-smoke and halogen-free requirements, subject to the applicable fire class and installation rules.
- Protected external routes: kanali, trays and other routes only where the declared construction covers exposure, water conditions and mechanical protection.
For indoor-to-outdoor routes, the sheath and cable design are selected for both environments, including UV exposure, burial conditions, moisture protection and the required fire classification.

The table covers 12/20 kV kabl, with maximum system voltage 24 kV. U 1×240/25, 240 mm² is the phase-conductor area and 25 mm² the screen area. Other voltage grades use their own insulation dimensions.
Current rating is calculated for circuit arrangement, lepljenje ekrana, temperatura okoline, soil or duct conditions and neighbouring heat sources.
N2XSH Project Support from XWA
XWA works from project drawings, BOQs and cable datasheets to define the proposed manufacturing scope. The factory overview introduces our cable production, inspection and export support.
Construction matched to the cable schedule
Conductor section, oblast ekrana, voltage grade, insulation dimensions and sheath requirements are defined together in the agreed manufacturing datasheet.
Testing and documentation agreed with the order
Plan inspekcije postavlja rutinske testove, evidenciju i sve zahtjeve za požar ili odobrenje specifičnih za projekat. Konstrukcijski nacrti i dogovoreni dokumenti za ispitivanje i inspekciju prate definisani obim isporuke.
Izvozno pakovanje usklađeno sa dužinama kablova
Dužina kablova i gotova masa određuju raspored bubnja i plan rukovanja. Označavanje bubnja i otpremni dokumenti su usklađeni sa odredištem i zahtjevima narudžbe.
N2XSH, N2XSY i N2XS2Y
| Model | Razlikovanje vanjskog omotača | Relevantna razlika u specifikacijama |
|---|---|---|
| N2XSH | Low-smoke, halogen-free sheath | Za tačnu konstrukciju moraju se definirati performanse ispitivanja na požar i prikladnost ugradnje. |
| N2XSY kabl | PVC plašt | PVC i LSZH imaju različite karakteristike gasa sagorevanja i materijala. |
| N2XS2Y kabl | PE omotač | Zaštita PE omotača sama po sebi ne znači otpornost na plamen, niskodimna konstrukcija. |
| N2XS(F)H / N2XS(FL)H | Plašt bez halogena sa dodatnim barijerama za vodu | (F) identifikuje uzdužno blokiranje vode; (FL) dodatno identifikuje radijalnu barijeru vlage u navedenom dizajnu. |
Poređenje se odnosi na SN konstrukcije zaštićene bakrom. Dizajn aluminijumskog provodnika NA2XSH takođe menja materijal faznog provodnika. Trojezgreni N2XSEH postavlja tri ekranizirana fazna jezgra unutar zajedničkog omotača i trebaju svoje vlastite dimenzije i podatke o nazivu.
Dva promjera koja su bitna na kraju
Prečnik preko izolacije određuje sučelje za kontrolu napona završetka; ukupni prečnik kabla određuje spoljašnji ulaz ili brtvu. Ove dimenzije služe različitim dijelovima sklopa dodatne opreme.
U odabranom 240/25 referenca, prečnik izolacije je 31 mm dok je kompletan prečnik kabla približno 43 mm. Koristeći 43 mm za odabir izolacijskog sučelja zbunjuje te površine. Tolerancije proizvodnje i vlastita ograničenja dodatne opreme ostaju dio procjene podobnosti.
Skidajući i lepljeni poluprovodljivi ekrani koriste različite metode pripreme. Isporučeni tip ekrana određuje proceduru i alate koji se koriste pri završetku.
N2XSH standardi, Vatrogasne performanse i ograničenja instalacije
IEC 60502-2 pokriva strujne kablove SN ekstrudirane izolacije u svom obimu. HD 622 / DIN VDE 0276-622 također pokriva uspostavljene SN dizajne bez halogena. Tehnička ponuda identifikuje primjenjivi građevinski standard i raspored ispitivanja.
Gustina dima, gasovi sagorevanja i širenje plamena se procenjuju odvojeno. The zvanični opis testa dima objašnjava IEC 61034-2. Projects requiring a CPR class or continued circuit operation during fire specify the corresponding classification or circuit-integrity evidence.
This unarmoured cable uses route-appropriate mechanical protection. The copper screen performs its electrical duty, while dedicated layers can provide specified water blocking. See the MV cable bending radius and pulling tension guide for handling and route constraints.
N2XSH Specifications and Quotation Questions
Can XWA review an N2XSH cable schedule for quotation?
Da. XWA accepts cable schedules, BOQs and project specifications for quotation. Voltage, conductor and screen sections, fire requirements, quantity and destination define the proposed order.
What affects the N2XSH cable price per metre?
Conductor and screen sections, voltage grade, sheath requirements, testovi, production length and packing determine the cable quotation. Freight follows the agreed delivery basis and destination.
Is N2XSH a fire-resistant cable?
N2XSH uses a low-smoke, halogen-free sheath. Where continued circuit operation during fire is required, the cable needs a suitable fire-resistant design and corresponding circuit-integrity test.
Can N2XH replace medium-voltage N2XSH?
N2XSH has the insulation and electrical screens required for its MV rating. N2XH is a separate LV design; each must be used within its specified voltage and application scope.
