Standards

  • International
    IEC 60092-350; IEC 60092-353; IEC 60092-360; IEC 60228; IEC 60332-1; IEC 60332-3-22; IEC 60754-1; IEC 60754-2; IEC 61034

Application

Motor supply cable for frequency converters controlled low voltage AC drives on ships, called VFD applications. MPRXCX® FLEXISHIP® EMC cables are designed with a special coverage, copper-polyester tape and braid, which provide a 100% EMC protection. Insulation with low dielectric constant is used to reduce reflected wave voltage peak magnitude. 
Symmetrical insulated ground wires, placed in corner, can reduce reflected wave and return common mode noisy currents back to the drive. Enhanced insulation is implemented for 1.8/3(3.6) kV cable to fulfil periodic peak voltage up to 3 kV due to harmonics.
These cables are used on board of ships in all locations for fixed installations.
