WDZB1-YJY Good flame retardancy XLPE Insulated and Sheathed Power Cable

Conductor

 Copper. Cross-sectional range- 1.5 mm² to 1000 mm² (0.6/1kV grade).  

Insulation

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

Sheath

 Polyolefin material, meeting halogen-free and low-smoke requirements.  

Rated voltage

 0.6/1kV (most common).  

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

 Single-core ≥ 20D, multi-core ≥ 15D.  

Combustion performance rating

 B1 grade - This is its most critical parameter, requiring compliance with all B1 grade specifications of GB 31247.  

Halogen-free performance

 pH value ≥ 4.3, conductivity ≤ 10 μS/mm (typically requiring higher performance).  

Low smoke performance

 Indicators such as smoke toxicity and smoke density meet B1 grade requirements, with light transmittance typically required to be above 60%.  

Other combustion performance

 Must also be evaluated for combustion calorific value, flame spread, heat release rate, and total heat release, etc., with extremely comprehensive requirements.
