Lead sheathed and armored cables

N2XSYKYRY , N2XSYKYBY , NA2XSYKYRY , NA2XSYKYBY

Applications:
• High Voltage cables are used for bulk transmission of power over 30,000 volts from power plant sites to primary distribution networks or central grid. The cables can also be installed on the racks, direct buried or in conduits.
• Armored types would be able to bear external mechanical forces.
• Lead sheathed types are designed to be used in any applications where the cables may be subjected to solvent penetration or corrosive attack or hydrocarbons.

Product Description:
In the voltage designation of U0/U(Um), The rated voltages of the cables considered in IEC standard are as follows: U0/U(Um)=26/45 to 47(52)KV - 36/60 to 69(72.5)KV - 64/110 to 115(123)KV - 76/132 to 138(145)KV - 87/150 to 161(170)KV.
U0 is the rated power frequency voltage between conductor and earth or metallic screen.
U is the rated power frequency voltage between conductors.
Um is the maximum value of the "highest system voltage" for which the equipment may be used.
