Power & Control Cables

Introduction
ATC make Power and control cables as per  IS 1554:1988, which pertains to PVC Insulated (Heavy Duty) Electric Cables for working voltages up to and including 1100 volts:

Scope:

  • This standard covers requirements and tests for armoured and unarmoured single-core, twin-core, three-core, and multi-core PVC insulated and sheathed cables.
  • These cables are used for electric supply and control purposes.

Construction and Features:

  • Conductor Material: The conductors can be made of aluminium or copper.
  • Conductor Construction: Conductor types include solid (Class 1) or stranded (Class 2).
  • Number of Cores: The cables can have single-core to multicore configurations.
  • Insulation Type: The insulation can be either Type A or Type C.
  • Sheath Type: The outer sheath is classified as ST1 or ST2.
  • Armoured/Unarmoured: These cables can be armoured or unarmoured.

Operating Voltage:

  • These cables may be operated continuously at a power frequency voltage up to 10 percent higher than the rated voltage.

Short Circuit Ratings:

  • The short circuit ratings of cables covered by this standard are under opreparation.
