Elektrisiteten fra opprinnelsespunktet strømmer gjennom strømkabler, som er uunnværlige komponenter i elektriske systemer.
– Strømkabelfamilietyper:
Strømkabler er vanligvis gruppert i familier basert på nominell spenning, ledermateriale, isolasjonstype og andre egenskaper. Noen vanlige strømkabelfamilier inkluderer:
1. Polyvinyl Chloride (PVC) Insulated Power Cables: These types use PVC as the insulation material for low and medium voltage uses such as residential and commercial wiring.
2. Cross-linked Polyethylene (XLPE) Insulated Power Cables: These ones possess outstanding electrical properties and are suitable for high and extra-high voltage applications. They are widely used in power distribution networks.
3. Rubber Insulated Power Cables: These have rubber as the insulating material known for its bendability and toughness making it ideal in portable power or industrial applications.
4. Armored Power Cables: Metallic protective layer like steel or aluminum gives birth to armored cables which provide mechanical strength and resistance to any form of damage that may be met along the way. This is why they are popularly preferred in underground and outdoor installations.
– Voltage Vurdering i strømkabelfamilien:
Kabelprodukter finnes i forskjellige spenningsklassifiseringer ment å passe til ulike bruksområder, med noen vanlige klassifiseringer som er:
1. Low Voltage (LV) Cables: Low voltage (LV) cables have a maximum operating voltage of less than 1 kV which means they can be applied in domestic house wiring as well as commercial buildings.
2. Medium Voltage (MV) Cables: MV cables come with a range of voltages between 1 kV to 35 kV serving distribution networks as well as factories among other industrial places.
3. High Voltage (HV), Extra High Voltage (EHV) Cables: HV and EHV cables have highest operating voltages above 35kV even up to 230kV & more for long distance transmission plus substation applications.
– Ledere i strømkabelfamilien:
Ledere i strømkabler kan være laget av kobber, aluminium eller aluminiumstvunnet stålkjerne (ACSR). Valg av ledermateriale avhenger av faktorer som kostnad, konduktivitet, mekanisk styrke og korrosjonsbestandighet.
– Bruksområder for strømkabelserien:
Strømkabel-serienbrukes i et bredt spekter av applikasjoner, inkludert;
1. Residential and commercial buildings: PVC insulated cables are often used for wiring in residential and commercial buildings.
2. Distribution networks: XLPE insulated cables and armored cables are used for power distribution and ensure efficient and reliable power transmission.
3. Industrial applications: Rubber insulated cables and ACSR conductors are often used in industrial environments such as factories and power plants where durability and high conductivity are essential.
4. Renewable energy: There exist special features of some cables like UV resistance, flexibility which make them suitable to be installed at renewable energy facilities eg solar or wind farms.
Strømkabelserien omfatter ulike typer kabler som er utformet for å passe til forskjellige elektriske eller miljømessige krav. For å velge riktig kabel for et bestemt prosjekt, er det nødvendig å vite om de forskjellige seriene sammen med deres applikasjoner.
