    ABNT NBR 11873 Medium Voltage Protected Aluminum Cable

    DOWNLOAD CATEGORY SPECIFICATIONS

    Product Details

    Product parameter

    Application

    Medium Voltage Protected Aluminum Cable is called cable aluminio protegido media tensión or conductor aluminio protegido in Spanish, which is indicated for compact primary medium voltage energy distribution networks. The protected cable layer is resistant to electrical routing and weathering. This increases the reliability of the overhead distribution network, which prevents discharges and shutdowns, in occasional contact with grounded objects and trees.

    Performance

    1.Electrical performance:15kV,25kV,35kV

    2.Chemical performance :chemical,UV&oil resistance

    3.Mechanical performance: Minimum bending radius:10 x cable diameter

    Construction

    Conductor:1350 aluminum wires, compact class 2 cording, with longitudinal moisture blocking, according to NBR NM 280.

    Semiconductor layer:: Thermostable material (XLPE) or thermoplastic (PE) (even for 35 kV cables, optional for 15 and 25 kV cables).

    Protective layer: This cover, applied simultaneously with the semiconductor layer, can be made up of one or two layers of thermostable material (XLPE), or two layers of polyethylene LDPE/HDPE or XLPE/HDPE, in the case of cables that have two layers. , the internal one will be colorless and the external one will be the one that has the indicated coloration.

    Cable Marking and Packing Materials

    Cable Marking:
    printing, embossing ,engraving

    Packing Materials:
    wooden drum, steel drum, steel-wooden drum

    asdzxc3

    1.Cross-linkable semiconducting layer (XLPE)

    2.Protective cover, outer layer (XLPE)

    asdzxc4

    1.Cross-linkable semiconductor layer (XLPE)/PE

    2.Inner layer of protective cover (XLPE)/LDPE

    3.Outer layer of protective cover (XLPE)/HDPE

    Standard

    ABNT NBR 11873 – Cables covered with polymeric material for electrical energy distribution networks fixed in spacers, in voltages from 13.8 to 34.5 kV.
    ABNT NBR NM 280 – Insulated cable conductors (IEC 60228, MOD).
