Kan PE pijp hoogspanningskabel dragen?

2025-08-19

In de bouw en gemeentelijke engineering, PE buizen worden veel gebruikt in watervoorziening en drainage, communicatie en andere gebieden vanwege hun voordelen van corrosiebestendigheid, goede flexibiliteit en handige constructie. Maar veel gebruikers zullen vragen: kunnen PE buizen worden gebruikt voor de draadbescherming van hoogspanningskabels? Als een professionele leverancier van pijpleidingoplossingen, zal AD Pipeline u in detail analyseren vanuit het perspectief van materiaalkenmerken en technische specificaties. Haalbaarheidsanalyse van

PE buizen door hoogspanningskabels

PE buizen (polyethyleen buizen) hebben goede isolatie-eigenschappen en hun volumeweerstand is meestal groter dan 10 ¬ Ω · cm, wat goed presteert bij het leggen van midden- en laagspanningskabels. Voor hoogspanningskabels met een nominale spanning van 10kV en hoger moet echter op de volgende factoren worden gelet:

1. Isolatiesterkte: De sterkte van de stroomfrequentieafbraak van gewone PE-buis is ongeveer 20-30kV / mm, hoewel deze voldoet aan de basisisolatie-eisen, maar de gedeeltelijke ontlading die wordt gegenereerd door de langdurige werking van de hoogspanningskabel kan de veroudering van het materiaal versnellen

2. Thermische stabiliteit: De continue gebruikstemperatuur van PE-buis is over het algemeen -40 ℃ ~ 60 ℃. Wanneer de hoogspanningskabel wordt overbelast, kan de temperatuurstijging het tolerantiebereik overschrijden, wat resulteert in de vervorming van de buis

3. Mechanische eigenschappen: Het leggen van hoogspanningskabels gaat meestal gepaard met grote tractie. Het is noodzakelijk om ervoor te zorgen dat de PE-buis voldoende ringstijfheid heeft (SN8 en hogere rangen worden aanbevolen)

Professioneel advies voor AD-buizen

Als deelnemer aan de industriestandaard worden AD-buizen aanbevolen in projecten voor de bescherming van hoogspanningskabels:

1. Spanningsrangverdeling: De verdikte PE machtspijpen (zoals AD MPP gewijzigde PE pijpen) kunnen voor kabels onder 10kV worden gebruikt, en de speciale machtsringen

2 worden geadviseerd voor 20kV en hierboven. Aanpassing van het legmilieu: De coëfficiënt van de bodemthermische weerstand het testen wordt vereist tijdens het directe begraving het leggen om ervoor te zorgen dat de het werk temperatuur van de pijp niet de ontwerpdrempel

3 overschrijdt. Speciale behandelingsvereisten: In een sterk elektrisch veldomgeving, zouden PE buizen die door speciale formuleringen worden gewijzigd moeten worden gebruikt. De antistatische PE pijpen van AD pijpen kunnen bij 10-10Ω · cm worden gecontroleerd door het toevoegen van koolstof zwarte masterbatch, die statische elektriciteitsophoping effectief elimineren

Voorzorgsmaatregelen van de projectuitvoering

1. Pijpselectie: moet in overeenstemming zijn met de "Electric Power Engineering Cable Design Standard" GB50217, kies ervoor om te voldoen aan de GB / T 15558.1-norm van PE-buis, AD-pijpleiding om te voorzien in een dichtheid van 110-φ 200mm specificaties van power buizen zijn door middel van de typetest

2. Constructiespecificaties:

- pijp top begraven diepte van niet minder dan 0,7 m, door de sectie moet worden geïnstalleerd behuizing bescherming

- bij gebruik van sleufloze technologie, tractie snelheidsregeling binnen 1,5 m / min

- interface om afdichting behandeling te doen, wordt aanbevolen om AD speciale hot-melt docking machine te gebruiken om de laskwaliteit

3 te waarborgen. Na onderhoud: regelmatige inspectie van pijpleiding aardingsweerstand (moet minder dan 10 Ω), gevonden dat pijp scheuren of verkleuring in de tijd te vervangen

Conclusie

PE pijp onder specifieke omstandigheden kan worden gebruikt voor hoogspanningskabel AD Pipeline herinnert gebruikers eraan dat speciale buizen zoals MPP-stroombuizen of CPVC-stroombuizen de voorkeur verdienen in hoogspanningsprojecten van 110kV en hoger.
