BIS CERTIFICATION FOR CROSS-LINKED POLYETHYLENE INSULATED THERMOPLASTIC SHEATHED CABLES IS 7098 (PART3)

Published Date: January 29, 2025 4 min Read

BIS certification is essential for Crosslinked Polyethylene (XLPE) Insulated Thermoplastic Sheathed Cables as per IS 7098 (Part 3): 1993. This standard ensures that these cables meet the necessary safety, durability, and performance criteria required for extra-high voltage (EHV) applications. XLPE insulated cables play a crucial role in power transmission and distribution networks, industrial systems, and large-scale infrastructure projects. Their superior insulation, thermal properties, and resistance to environmental factors make them a reliable choice for demanding electrical systems. Compliance with IS 7098 (Part 3) highlights a manufacturer's commitment to delivering safe and efficient electrical solutions.

IS 7098 (Part 3): Crosslinked Polyethylene Insulated Thermoplastic Sheathed Cables

IS 7098 (Part 3) specifies the technical requirements for XLPE insulated thermoplastic sheathed cables used in EHV systems, typically for voltages above 33 kV. The standard defines critical parameters, including conductor material, insulation thickness, sheath composition, and cable construction. These cables are engineered to deliver excellent electrical performance, including high dielectric strength, thermal stability, and mechanical robustness. They are also designed to withstand environmental challenges like moisture, UV exposure, and chemical degradation. Extensive testing ensures their suitability for extreme conditions in high-demand applications.

Benefits of BIS Certification for XLPE Insulated Thermoplastic Sheathed Cables

Mandatory BIS certification under IS 7098 (Part 3) guarantees adherence to stringent national standards for safety and quality. For end users, it assures dependable performance in EHV applications, reducing risks of electrical faults, insulation failure, or overheating. For manufacturers, certification enhances market credibility, supports customer trust, and demonstrates compliance with critical infrastructure standards. It also provides a competitive edge, signaling a commitment to delivering safe, high-quality electrical products.
