Часто задаваемые вопросы
What is a high voltage cable?
A high voltage cable is a fully insulated power cable system used for transmission-level voltage. It includes the conductor, semiconductive screens, main insulation, metallic screen or sheath and outer protection layers required to control electric stress and safely transmit power.
What voltage range does XWA high voltage cable cover?
XWA manufactures common high voltage project classes from 66kV to 500kV, including 66kV, 110кВ, 132кВ, 220кВ, 275kV and 500kV cable designs.
Which standards apply to HV XLPE cable?
МЭК 60840 is normally used for extruded-insulation power cables above 30kV and up to 150kV. МЭК 62067 is normally used for extruded-insulation power cables above 150kV and up to 500kV. Project specifications may also include national grid or utility requirements.
Can HV cable be installed underground?
Да. Underground high voltage cable is widely used for urban transmission routes, подстанции, industrial intake lines and renewable energy grid connections. Cable spacing, термическое сопротивление почвы, laying depth, bonding mode and route protection affect the final design.
How are higher HV cable classes different?
Higher high voltage cable classes such as 220kV, 275kV and 500kV require more demanding control of insulation thickness, metallic sheath design, аксессуары, testing and installation conditions. XWA treats 220kV as a high voltage transmission cable class.
How does XWA control HV cable production quality?
XWA arranges HV cable production through joint manufacturing with qualified partner factories. XWA confirms the project specification, coordinates conductor preparation, insulation extrusion, screen and sheath configuration, dimensional checks and routine test records, and controls the agreed documentation and delivery scope.
How does XWA prepare an HV cable quotation?
XWA reviews voltage designation, conductor material and size, длина маршрута, метод установки, metallic sheath or screen requirement, bonding arrangement, short-circuit level, материал оболочки, drum length and required standard before preparing the cable offer.
