ATC Power Cables

ATC Power Cables with XLPE Insulation

Power cables with ISI mark as per IS 7098:1988, which covers Crosslinked Polyethylene (XLPE) Insulated PVC Sheathed Cables for working voltages up to and including 1100 volts:

Scope:

  • The standard applies to both armoured and unarmoured single, twin, three, four, and multi-core cables.
  • These cables are designed for electric supply and control purposes.

Construction:

  • Insulation: The cables feature crosslinked polyethylene (XLPE) insulation, which enhances their durability and electrical properties.
  • Sheath: The outer sheath is made of PVC (polyvinyl chloride), providing additional protection.

Features of XLPE-Insulated Cables:

  • High Thermal Resistance: XLPE does not melt like thermoplastics and remains thermally resistant even at elevated temperatures (up to 120°C for longer periods and up to 250°C for short durations without mechanical or electrical load).
  • Enhanced Properties: Compared to ordinary polyethylene (PE), XLPE offers significantly improved properties.
  • Dielectric Excellence: XLPE has excellent dielectric properties, making it suitable for medium and high-voltage cables (up to 380 kV AC and several hundred kV DC).
  • Rated Maximum Conductor Temperature: XLPE-insulated cables have a rated maximum conductor temperature of 90°C and an emergency rating up to 140°C, depending on the standard used.
  • Shear Modulus: Increasing crosslinking density enhances the shear modulus, especially in high- voltage cable applications.

Advantages of XLPE Insulation:

  • Cost Efficiency: XLPE insulation provides cost-effective operation and procurement compared to older impregnated paper systems.
  • Environmental Friendliness: It has lower environmental and maintenance requirements.
  • Wide Application Range: Used in power transmission, distribution, and other critical systems.
  • Quality assurance: All cables are ISI marks with BIS standards ISI:1554 (Part-1) 1988, ISI:7098/1990, ISI:14255 (Part-1)

Applications of XLPE-Insulated Cables:

  • Power Transmission and Distribution: XLPE cables are widely used for power transmission and distribution purposes.
  • High Voltage Electrical Cables: XLPE serves as insulation for high-tension electrical cables.
  • HVAC Industry: Used on copper pipes, MS pipes, drainpipes, chilled water pipelines, AC ducts, and air handling units.
