The cross-linked polyethylene (XLPE) insulation ensures enhanced thermal performance, chemical resistance, and durability, making it ideal for long-term use in power transmission networks. The thermoplastic sheath provides additional mechanical protection, ensuring the cable’s longevity and reliability. BIS certification guarantees that these cables comply with all the necessary safety and quality standards for use in demanding electrical environments.

Introduction

The BIS certification for Cross-Linked Polyethylene Insulated Thermoplastic Sheathed Cables under IS 7098 (Part 3) : 1993 is mandatory for cables used in high-voltage applications, ranging from 66 kV to 220 kV. The standard ensures that these cables meet high safety, performance, and durability requirements, making them suitable for power transmission networks that handle large amounts of electrical power over long distances. Compliance with IS 7098 (Part 3) : 1993 ensures that the cables provide reliable, safe, and efficient operation in industrial, commercial, and utility applications.

Why is BIS Certification Necessary for Cross-Linked Polyethylene Insulated Thermoplastic Sheathed Cables?

BIS certification for Cross-Linked Polyethylene (XLPE) Insulated Thermoplastic Sheathed Cables is critical due to the demanding nature of high-voltage power transmission applications. These cables must be designed and manufactured to handle high electrical loads while providing reliable insulation and protection. Certification ensures that the cables meet rigorous standards for insulation integrity, mechanical strength, and environmental resistance. The BIS certification process helps manufacturers maintain consistent quality, ensuring that their products meet both Indian and international standards for safety and performance.

Overview of Indian Standard IS 7098 (Part 3) : 1993

Indian Standard IS 7098 (Part 3) : 1993 outlines the specifications for Cross-Linked Polyethylene (XLPE) Insulated Thermoplastic Sheathed Cables used in high-voltage applications (66 kV to 220 kV). The standard includes material specifications, requiring XLPE insulation for its high dielectric strength and resistance to heat, moisture, and chemicals. It also details electrical properties to ensure the cables can withstand electrical stresses, and mechanical properties to ensure they endure operational challenges like bending and abrasion. Safety standards focus on fire resistance and temperature tolerance. Additionally, the standard mandates rigorous testing for insulation integrity, mechanical strength, and environmental resistance. Compliance ensures reliable and durable performance in critical high-voltage power transmission systems.

Process for BIS Certification

The BIS certification process for Cross-Linked Polyethylene Insulated Thermoplastic Sheathed Cables under IS 7098 (Part 3) : 1993 involves the following steps:

1. Application Submission: Manufacturers submit a complete application form, along with required documentation, to BIS for certification.
2. Documentation Review: BIS reviews the submitted application to ensure all necessary details are provided.
3. Factory Inspection: BIS officials conduct an on-site inspection of the manufacturing facility to assess the production process, equipment, and quality control measures in place.
4. Sample Testing: Product samples are tested in BIS-approved laboratories to verify compliance with the specifications outlined in IS 7098 (Part 3) : 1993.
5. Certification Grant: Upon successful completion of the inspection and testing, BIS grants certification, allowing the manufacturer to use the ISI mark on their cables.

Documents Required for BIS Certification

To apply for BIS certification, manufacturers must submit the following documents:

• Application form
• Details of the manufacturing process
• Quality control procedures
