Testing is a vital part of cable / conductor manufacturing and all raw materials and finished cables are thoroughly tested to ensure quality control. The Company has a well equipped inhouse testing laboratory for carrying out electrical, mechanical and chemical tests which are required as per relevant specifications. The various tests as provided in the Indian Standards are carried out regularly. These are classified in three different groups:

  • Routine Tests
  • Type Tests
  • Acceptance Tests
  • Special Tests
Routine Tests

The following tests constitute Routine Tests, which are carried out on each and every length of cable before it leaves the factory:

Conductor Resistance Test

This test ensures that conductor resistance is with the specified limits, thereby ensuring that the continuity of conductor is maintained throughout the cable length and that the conductor has the required cross section area. The DC resistance is measured at room temprature and is then corrected to standard reference temperature at 20°C.

High Voltage Tests

This test ensures that the insulation will safely withstand the rated voltage within permissible normal operation.

Type Tests

These tests are carried out on samples taken from each production lot. They are carried out to prove conformity as regards the general qualities and design to the specification of particular type of cable. These tests are ,enumerated in the relevant Indian Standards.

Acceptance Tests

The customers can request the various acceptance tests as provided in the relevant Indian Standard to be carried out before accepting the cables.

Special Tests 

Special tests are those tests which do not get covered under routine or type or acceptance tests. Generally special tests are conducted to assess a particular property or a set of properties, which have been built in the cable to exhibit desired requirement during its operation.
