High-Voltage Insulation System
XLPE insulation, metallic screen and sheath design must be reviewed according to rated voltage and system earthing.
High Voltage Power Cable
High Voltage Power Cable for high-voltage power distribution and project cable selection.
High Voltage Power Cable is positioned for high-voltage network routes where insulation system, screen design, voltage class, testing and project engineering review must be confirmed before supply.
Product Overview
High Voltage Power Cable requires project-level engineering review before final selection. Confirm voltage class, conductor material, insulation system, armour or screen design, sheath route and installation condition, plus testing, bonding, earthing and route conditions before treating any datasheet as order-ready.
Applications
- high-voltage transmission and grid interconnection routes
- substation incoming/outgoing circuits and utility network expansion
- underground HV cable systems where insulation, screen and sheath design require engineering review
- large power, renewable energy or infrastructure projects requiring project-specific test and document confirmation
Construction
Copper or aluminum conductor as specified; XLPE or PVC insulation according to voltage grade; metallic screen and water-blocking layers for MV/HV routes. Final dimensions, electrical values and test requirements should follow the selected standard and project datasheet.
Marking on Cable
FARWALK CABLE – High Voltage Power Cable – [standard] – [voltage] – [core x size] – [year] – [meter mark]
Cable Identification
- Core identification can follow color or number marking according to standard and project requirement.
- Outer sheath color, voltage marking and meter marking can be reviewed before production.
Standards
- IEC 60840 for HV cable systems
- IEC 62067 for EHV cable systems where applicable
- project utility / national standard requirements
Main Features
Routine and Type Test Focus
Partial discharge, voltage withstand, sheath testing and accessory compatibility are central to HV cable review.
Project Engineering Required
For High Voltage Power Cable, route length, installation method, conductor size, bonding and national grid requirements should be confirmed before supply.
Product Selection Guide
Voltage Class
Start with the rated voltage; LV, MV, HV and EHV cables use different standards, tests and construction logic.
Installation Route
Confirm tray, duct, direct burial, tunnel, outdoor, indoor or underwater-related conditions before selecting armour and sheath.
Conductor / Core Choice
Review copper or aluminum, single-core or multicore construction by current rating, voltage drop and installation layout.
Fire / Mechanical Requirement
Select LSZH, fire-resistant, armoured, water-blocking or special sheath options only when the route requires them.
