MV XLPE Insulated Electrical Power Cable

MV XLPE Insulated Electrical Power Cable


Standards of MV XLPE Insulated Electrical Power Supply Power Station Cable

The cable is manufactured according to IEC 60502.2, IEC 60502.1, AS/NZS 1429.1, AS/NZS 5000.1, BS 6622/7835, BS 5467, BS 6746, BS 6346, VDE 0276, ASTM, ABNT etc. It is suitable to be installed in the power line with rated voltage from (U0/U)0.6/1kV to 19/33kV for power transmission.

Application of MV XLPE Insulated Electrical Power Supply Power Station Cable

The electric cable is applied to transmit and distribute power in power transmission and distribution system of 1kV~35kV or lower. It is widely adopted in the fields including power, construction, industry, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial re-place of PVC insulation or XLPE power cable.

Cable Properties of MV XLPE Insulated Electrical Power Supply Power Station Cable

Special features which we can offer for LV and MV cables:

* Watertight construction (both radial and longitudinal).

* Resistant to heavy vibration.

* Available in long delivery lengths to reduce number of joints.

* Corrosion-free screen area.

* Copper or aluminum conductor up to 2500mm².

* Different options for outer PE jackets (LDPE, MDPE & HDPE).

* Different options for PVC, LSF, LSZH & FRPVC, being anti-termite or UV resistant as per

BS 7835, IEC 60332 etc.

* Strippable insulation screen.

* Increased armour conductivity by insertion of hard drawn copper wires in armour.

The maximum rated temperature of MV XLPE Insulated Electrical Power Supply Power Station Cable

XLPE insulated,the maximum operating temperature of conductor shall exceed 90℃when the cable is used for long not period. The temperature of conductor shall not exceed 250℃ at short circuit for 5 seconds.

PVC insulated,the maximum operating temperature of conductor shall exceed 90℃ or 70 ℃ when the cable is used for long not period. PVC insulated the temperature of conductor shall not exceed 160℃ at short circuit for 5 seconds.

Installation requirement of MV XLPE Insulated Electrical Power Supply Power Station Cable

The installation of cable is not limited by the difference of elevation along the route. The ambient temperature should not be below 0℃ during installation. The permissible bending radius for cable shall be complied with the following regulations:

For single-core: R>20(D+d) +/-5%

For multi-core: R>15(D+d) +/-5%

Where:R—bending radius (mm) , D—overall diameter of the cable (mm) , d—diameter of conductor (mm).

Single core cable of using in AC circuit shall be without armour or with steel wire armour and shall not be laid in magnetic ducs.
