MV Power Cable for 6kV to 35kV Distribution Projects
MV power cable covers common IEC-rated cables from 3.6/6(7.2)kV to 18/30(36)kV, together with regional and project-specific 35kV-class constructions for distribution, industrial and renewable energy systems.
XWA MV Power Cable
As a medium voltage cable manufacturer, XWA supplies 6kV to 35kV cable constructions for distribution networks, substations, industrial plants and renewable energy collection systems, with copper or aluminum conductors, screened insulation systems, armoring options and sheath materials matched to project specifications.
XWA’s engineering team develops each MV cable construction according to the rated voltage, conductor size, core arrangement, screen design, armoring requirement, water-blocking condition and installation environment for underground, duct, tray and direct-burial routes.
MV Cable by IEC Voltage Rating
XWA organizes this product group around IEC U0/U(Um) voltage designations and the common market names used for distribution, substation and industrial power systems.
North American MV Cable
North American medium voltage cable classes are normally named by nominal system voltage, while IEC cable pages use U0/U(Um) designations. XWA separates these terms so voltage selection, standards discussion and cable construction remain clear.
5kV, 15kV, 25kV and 35kV Classes
North American MV Cable covers nominal voltage classes used in utility, industrial, renewable energy and feeder systems.
Different Naming Basis
IEC pages use U0/U(Um), such as 8.7/15(17.5)kV, while North American schedules commonly use 5kV, 15kV, 25kV or 35kV class names.
Project Specification Review
XWA reviews conductor, insulation level, shield system, jacket, installation route and required standard scope before confirming the cable construction.
MV Cable by Model Designation
XWA also supplies published medium voltage model pages for IEC and European-style cable designations used in project specifications and tender schedules.
MV power cable is used between low-voltage distribution and high-voltage transmission systems. It supports feeder circuits, transformer substations, industrial power intake, wind and solar collection networks, mining power distribution and municipal underground grids where screened insulation and controlled earthing are required.
