YJV32 | YJLV32 | XLPE insulation, thin steel-wirearmor,PVC sheath power cable | Be applicable to the well, water inside and fall in the badsoil, the cable cans bear the equal dint outside the machine with pull thedint . |
YJV72 | YJLV72 | XLPE insulation, have no the magnetism thick steel-wirearmor,PVCsheath power cable | |
YJV42 | YJLV42 | XLPE insulation, thick steel-wirearmor,PVC sheath power cable | Be applicable to the well, underwater with the bottom of sea, the cablecans bear the bigger pressure with lead to pull the dint. |
Special Note | , 6272., . The single-core magnetism material packsthe cable is not suitable for to use for the AC power supply back track, thenecessity hour eligibility uses the single-core 62 or 72 type pack the cable. Disallow the cent to cross the magnetism piping mutually whensingle-core cable establish, the in order to prevent results in the descent thatcable transport electric current ability. | ||
