N2XS2Y cable is a medium voltage power cable that meets international standards and is designed for efficient and reliable power transmission. Its core is insulated with cross-linked polyethylene (XLPE) insulation, which provides excellent electrical properties and thermal stability and is suitable for use in power systems with rated voltages of 12/20 kV or 18/30 kV. The construction of the N2XS2Y model manufactured by ZMS Cables consists of a high-purity copper conductor, a double-layered, semi-conductive shield, and a braided shield of copper wires, which ensures uniform distribution of the electric field and excellent EMC compatibility. The outer jacket is made of weather-resistant, flame-retardant PVC, providing excellent mechanical protection and environmental suitability for direct burial, conduit, or indoor laying.

NOTE:
1. The flow-carrying capacity is affected by the laying method (direct burial, pipeline, in air) and ambient temperature, and needs to be adjusted according to the actual working conditions.
2. If armored type (such as N2XS2Y-FR) is required, the outer diameter and weight will be increased.
3. The above data is for general reference, we suggest contacting ZMS Cable for detailed information.

ZMS Reminds Selection Notes
Voltage Matching: select 12/20 kV or 18/30 kV according to the highest system voltage.
Laying Method: direct buried need to choose steel belt armored models (such as N2XS2Y-FR), non-armored applicable to pipeline
Ambient Temperature: high-temperature environment is recommended to choose heat-resistant PVC or LSZH sheath variants
Compared with YJV22 and other models, N2XS2Y model cables pay more attention to shielding performance and European standard compatibility, which is very suitable for export projects.
ZMS Customized Service: special sheath enhancement versions such as Flame Retardant (FR), Termite Resistant, and Rodent Bite Resistant are available.
