7,2/35 kV XLPE INSULATED SINGLE CORE MEDIUM VOLTAGE POWER CABLES

YXC7V-R (TSE) | N2XSY (VDE) | 2XSY (IEC) Cu / XLPE / SC / PVC

20.3/35 kV XLPE insulated single core medium voltage power cables are designed
for reliable power transmission in medium voltage distribution networks.
Manufactured with copper conductor, XLPE insulation, metallic screen (SC),
and PVC outer sheath, these cables provide excellent electrical performance,
mechanical strength, and long-term operational reliability.

YXC7V-R / N2XSY / 2XSY cables are suitable for indoor and outdoor installations
where high current carrying capacity, thermal stability, and compliance with
international standards are required.

Applications

• Medium voltage power distribution networks
• Power plants and substations
• Industrial facilities and heavy industry
• Underground cable installations
• Urban and rural energy infrastructure projects
• Utility and grid expansion projects

Cable Construction

• Conductor: Annealed copper conductor
• Insulation: Cross-linked polyethylene (XLPE)
• Metallic Screen: Copper wire screen (SC)
• Outer Sheath: Polyvinyl Chloride (PVC)

The XLPE insulation ensures high dielectric strength and thermal resistance,
while the copper screen provides effective electrical shielding and grounding.
The PVC outer sheath offers mechanical protection and resistance against
environmental factors.
