IS 13098:1992 Part 1 is the Indian Standard (BIS) for cross-linked polyethylene insulated pvc sheathed cables for working voltages up to and including 1100 v - part 1: for copper and aluminium conductors. This standard specifies the requirements and testing methods for single and multi-core cross-linked polyethylene (XLPE) insulated and PVC sheathed cables with copper or aluminium conductors. It covers cables for working voltages up to and including 1100V, suitable for fixed electrical installations.
Specifies requirements for low voltage XLPE insulated, PVC sheathed cables with copper or aluminium conductors for applications up to 1100 V.

Practical Notes
! The key advantage of these cables over PVC insulated cables (IS 1554) is the higher conductor operating temperature (90°C vs 70°C), allowing for higher current carrying capacity.
! For new projects, IS 7098 (Part 1) is often preferred as it is a more modern and comprehensive standard for XLPE insulated cables up to 3.3 kV.
! Ensure correct identification of cores as per Clause 12, especially for multi-core cables, to prevent incorrect phase connections.

Key Differences
≠The nominal insulation thickness required by IS 13098 is generally greater than that specified in IEC 60502-1 for the same conductor size. For example, a 50 mm² conductor requires 1.4 mm insulation in IS 13098, versus 1.0 mm in IEC 60502-1.
≠IS 13098:1992 mandates a specific PVC sheath compound (Type ST1 per IS 5831), whereas modern international standards like IEC 60502-1 offer a wider range of sheath options, including different PVC grades (e.g., ST2) and Low Smoke Zero Halogen (LSZH) compounds.
≠The routine voltage test in IS 13098 is 3.0 kV AC for 5 minutes, while the current IEC 60502-1 standard specifies a higher test voltage of 3.5 kV AC for 5 minutes for the equivalent 0.6/1 kV rating.
≠Fire performance testing in the 1992 version of the Indian standard is limited to a basic single cable flame retardance test (per IS 10810 Pt 53). Contemporary international standards mandate a more extensive suite of fire tests, including tests on bunched cables (IEC 60332-3), smoke density (IEC 61034), and corrosivity of gases (IEC 60754).
Key Similarities
≈Both IS 13098 and its international counterparts specify the use of Cross-linked Polyethylene (XLPE) as the primary insulation material, recognizing its high dielectric strength and thermal properties.
≈The maximum continuous conductor operating temperature is specified as 90°C in both the Indian standard and international equivalents like IEC 60502-1 for XLPE insulated cables.
≈The fundamental construction principle is identical: annealed copper or aluminium conductors, extruded XLPE insulation, laying up of cores (for multi-core cables), and an overall extruded PVC sheath.
≈The maximum DC resistance values for conductors are closely aligned, as both IS 8130 (referenced by IS 13098) and IEC 60228 (the international reference) specify nearly identical values, ensuring comparable current carrying capacities for a given cross-section.
