Low Voltage (LV) Power Cables
LV Power cables are designed to be laid in power supply networks over, on, inside, and under plaster in dry, damp, and wet rooms as well as in brickwork and concrete.
This low voltage power cable is suitable to be laid in water and underground. It is stable to UV radiation.
Variants of Power Cables:
Low Voltage Power cables are generally Un-armoured or Armoured with or without shielding. The most commonly used armoring material is GI round wire or GI flat strips, however, sometimes Steel Wire Braiding is also used.
The shielded LV power cables are typical with a foil shield, braid shield, or a combination of the two. Or sometimes Copper Tape is also used as a shield.
Type of Insulation & Sheathing:
Low voltage wiring generally has PVC or XLPE insulation & PVC sheathing. However, other insulating materials are also used based for outer sheath based on the type of application & place of installation such as XLPE; PUR; LSZH Compound; Nylon; EPR rubber, etc
Conductor: Mostly Class 2 Stranded bare copper or tinned copper conductors. Sometimes Class 5 conductor stranding or Solid Conductors are also used.
Insulation: PVC or XLPE is the most common or TPE/ EPR/ Halogen-free compound
Cores laid & twisted to form the bunch
For Shielded Version: Aluminum Foil with Drain wire or Tinned copper braiding for EMI/EMC protection in low voltage wiring.
Outer Sheath: PVC/ XLPE/ POLYURATHANE/ EPR/ HALOGEN FREE COMPOUND / SILICON etc
Typical Voltage Grades:
600/1000 V or 660/1100 V
