Applications:
• LV power cables for energy supply are used for industry and distribution boards , power stations , panels , house connecting boxes , subscriber networks & street lighting . those cables are installed in open air , underground , indoor and in cable ducts .
• 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)=0.6/1(1. 2) – 1.8/3(3.6) 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.
