IS 9968 Testing Lab

IS 9968 part 2, covers the requirements of heat resisting elastomer insulated cables for fixed installation and flexible cables for single phase and three-phased systems, appropriate for voltage of 3.3 kV up to and including 33 kV.

These cables are appropriate for use where the combination of ambient temperature and temperature increase because of the load results in a conductor temperature not exceeding 90-degree under normal operating conditions and 250-degree under short circuit conditions.

Test Requirements of IS 9968 Testing (Part 2)

1. Physical Test on Round or Formed Wire
