BIS Certification For Cross-Linked Polyethylene Insulated Thermoplastics Sheathed Cables - IS 7098 (Part 3)

Introduction

An important standard required by the Ministry of Commerce and Industry, Department for Promotion of Industry and Internal Trade, is the ISI Certification (BIS) for Cross-Linked Polyethylene Insulated Thermoplastics Sheathed Cables (66-220KV) under IS 7098 Part 3. 

This accreditation guarantees that producers follow strict quality standards and testing protocols for these cables, which are necessary for the provision of electricity in three-phase AC-earthed systems.

Test Executed:

1. Copper purity test: Verifies the conductor material's quality, which is essential for effective electrical transmission.

2. Conductor Resistance: Confirms that the conductivity of the material used for the conductor satisfies performance requirements.

3. High voltage test: To minimize failures during operation, this test assesses how well the cable's insulation withstands high voltage strains.

4. Armour Resistance: The strength and longevity of the cable's armoring for protection against mechanical forces is determined by its armor resistance.

5. Annealing Test: The annealing test verifies the cable's resilience to temperature changes and thermal stability.

6. Tensile test: Evaluates the mechanical robustness and tension-resistance of the cable.

7. Wrapping test: Testing the integrity of the insulating sheath and cable wrapping is known as a wrapping test.

8. Insulation sheath thickness: Ensures consistent insulation thickness for best possible electrical insulation.

9. Tensile strength and insulation and sheath elongation: Indicates the flexibility and elongation characteristics of the cable.

10. Insulation Resistance: Evaluates the resistance of the insulation material to electrical leaks.

11. Test for shrinkage: Determines whether the cable's components are dimensionally stable under various circumstances.

12. Hot deformation test: To stop distortion, do a hot deformation test to see how the cable behaves at high temperatures.

13. Heat Shock test: The cable's resilience to abrupt temperature fluctuations is evaluated using the heat shock test.

14. Cold bend test: The cold bend test assesses the performance and flexibility of the cable at low temperatures.

15. Cold impact test: Examines the cable's ability to withstand mechanical impact at low temperatures using the cold impact test.

16. Thermal stability: Assures the cable won't break when exposed to high temperatures over an extended period of time.

17. Flammability Test: The cable's resistance to fire and combustion is established by the flammability test.

18. Flame Retardance: Evaluates how well a cable can put out a fire on its own.

19. Temperature Index: The maximum temperature at which the cable can function safely is indicated by the temperature index.

20. Smoke density: An important safety factor in confined places, it evaluates the quantity of smoke released in the event of a fire.
