The various tests carried out on TROPODUR cables are classified in three different groups:-

1) Routine Tests
2) Type Tests and
3) Acceptance Tests.

Control Room in Test Field

Routine Tests

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

(A) Conductor Resistance Test

The Test ensures that conductor resistance is within the specified limit, thereby verifying that the continuity of conductor is maintained throughout the cable length and that the conductor has the required electrical section D.C. resistance is measured at room temperature and is then corrected to standard reference temperature of 20°C.

(B) High Voltage Test

This test ensures that insulation will safely withstand and rated voltage with permissible variation in normal operation.

TROPODUR Cables are tested for the following voltage:

(C) Partial Discharge Test for 11 kV cable

This test involves detection and measurement of partial discharge occuring in screened cables.

(D) Insulation Resistance Test

This test determines insulation resistance and helps to detect insulation imperfection. It is desirable to have the insulation resistance as high as possible. At CCI we get IR values higher than specified in the standards which in turn contribute to longer cable life.

Type Tests

These tests are carried out on samples taken from each production lot. The are carried out to prove conformity as regards the general qualities and design to the specification of particular type of cables.

Acceptance Tests

These tests are carried out on samples taken from a production lot for the purpose of acceptance of the lot.

PACKING:

Cables will be generally supplied on drums.

The drums shall be wooden drums or collapsible steel drums at the discretion of the manufacturer.
