Home / Product / Medium voltage XLPE or PVC insulated power cable
CU or AL conductor, XLPE or PVC insulation, copper tape screen, PVC or LSZH sheath, with or without steel wire or steel tape armor, flame retardant, sun resistant, underground
It is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable. Power cables for power networks, underground, outdoors and in cable ducting
Operating characteristics
– Rated power-frepuency voltage U0/U: 3.6/6kv～26/35kv.
– Max.admissible operating temperature of the conductor:90℃.
– Max. short-circurt temperature of conductor shall not exceed 2500C. (5s maximum duration)
– The ambient temperature under installation should not below 00C.
– The bending radius of a single-core cable should not less than 20 times of the cable diameter.
The bending radius of a multi-core cable should not less than 15 times of the cable diameter.
