Standard
The electric properties of flame retardant XLPE cable are the same as those of ordinary XLPE cable. The combustion property of flame retardant cable complies with category A, B, C of bunched burning according to GB1266-90 (equivalent to IEC332-3). The construction and dimension are identical with ordinary XLPE cable except cables of ZRA-YJV and ZRA-YJLV. The flame retardant PVC is used as the inner covering and the sheath of cable.
PE cable:
Category A: ZRA-YJV、ZRA-YJLV、ZRA-YJV22、ZRA-YJLV22
Category B: ZRB-YJV、ZRB-YJLV、ZRB-YJV22
Category C: ZR-YJV、ZR-YJLV、ZR-YJV22、ZRA-YJLV22
The circumstance temperature is 40℃ in the air. The thermal resistivity of soil is 100℃cm/w.
