Conductor

 Copper (T, usually omitted). Cross-sectional range- 1.5 mm² to 1000 mm² (common for 0.6/1kV grade).  

Insulation

 Cross-linked polyethylene (XLPE), long-term allowable operating temperature of 90°C.  

Inner sheath

 Polyvinyl chloride (PVC).  

Armor layer (core feature)

 Fine round steel wire armor. Evenly distributes external tensile forces, enabling the cable to withstand significant axial tension.  

Outer sheath

 Polyvinyl chloride (PVC) protects the armor against corrosion.  

Rated voltage

 0.6/1kV (most common), 8.7/15kV, etc.  

Long-term allowable operating temperature

 Maximum conductor temperature- +90°C.  

Short-circuit temperature (5 seconds)

 Maximum +250°C.  

Installation temperature

 Should not be below 0°C.  

Minimum bending radius

 Very large.

Multi-core cables

 ≥ 15 × cable outer diameter (D) (due to the steel wire armor structure, bending is most difficult).  

Tensile strength

 Extremely high (core advantage). The steel wire armor can withstand the tensile forces from the cable's own weight and installation traction.  

Flame retardancy

 The standard type does not meet special flame-retardant requirements. For flame-retardant applications, ZC-YJV32 should be selected.  

Test voltage (0.6/1kV)

 3.5kV / 5 minutes (power frequency withstand voltage).
