2XSEYB2Y / A2XSEYB2Y Application
- Urban and Regional Distribution Networks: Used for the transmission and distribution of electrical energy, commonly found in the trunk or branch lines of urban and regional power grids.
- Substations and Industrial Power Supply: Provides power to transformer substations and small- to medium-sized industrial enterprises; suitable for industrial power distribution systems and within power plants.
- Installations Requiring High Mechanical Protection: Due to its double-layer steel tape armor (STA), it is particularly suitable for direct burial (in trenches) or locations prone to mechanical damage; however, it is not suitable for withstanding significant tensile forces.
- Diverse Installation Environments: Can be used indoors, in cable trenches, tunnels, shafts, cable trays, and even in some bodies of water; supports fixed installation.

2XSEYB2Y / A2XSEYB2Y Feature
- Insulation and Shielding: Features XLPE (cross-linked polyethylene) insulation, combined with inner and outer semiconductive layers and a copper metal shield, ensuring stable electrical performance and low partial discharge levels.
- Operating Temperature: The conductor’s continuous operating temperature can reach 90°C, and during a short circuit (lasting up to 5 seconds), the temperature can reach as high as 250°C, providing strong overload capacity.
- Double-Layer Sheath: The cable features an inner PVC sheath and an outer PE (polyethylene) sheath (Type ST7), providing excellent protection against moisture, corrosion, and abrasion.
- Bending Restrictions: Due to its relatively rigid structure, the minimum bending radius during installation is typically required to be 15 times the cable’s outer diameter.
