Quality

In the manufacture of cables, standard laid down operating procedures at each and every stage are followed to achieve quality. For quality end products, control starts from proper design of the product.All raw materails are selected carefully and only materials of high quality are used in production. Having done this, stagewise inspection is done to ensure conformity with relevant Indian/International Standards.


Stage-Wise Inspection

Wire Drawing :	Wire diameter Surface Shape Quality of joints in the wire
Stranding of Wires :	Quality of joints in the wire Compactness of conductor Shape of conductor Dimensions Resistance of Conductor Direction of Lay
Insulation :	Dimension over Insulation Thickness of Insulation Surface defects
Curing :	Hot Seat Test Tensile Strength & elongation (for XLPE insulation)
Laying Up :	Sequence of Cores Direction of Lay Diameter over laid up cores Circularity
Inner Sheath :	Thicknesss of Sheath Diameter over Sheath Surface Uniformity Circularity
Armouring :	Diameter of Wires Dimension of Strips Direction of lay, Coverage Porosity, quality of Joints of wires
Outer Sheath :	Thickness of Sheath Diameter over Sheath Tightness of Sheath Ovality, Eccentricity, Porosity Embossing

Tests
The tests on cables have been classified broadly in four categories as follows:


Routine Tests
Tests carried out on each Cable to check the requirement which are likely to vary during production.


Type Tets
Tests carried out to prove conformity with the specification. These are intended to prove the general qualities and design of a given type of cable.


Acceptance Tests
Tests carried out on samples taken from a lot for the purpose of acceptance of the lot.


Optional Tests
Special tests are carried out when required by agreement between the purchaser and the manufacturer.


Special tests required for FRLS Cables can also be carried out at our works i.e. Halogen gas generation test to IEC-754 (part-1) , Smoke generation test to ASTMD-2843, Oxygen Index test and Temperature Index test to AS T MD -2863, Flammability test to (1) IEC -332-3., flame resistant test to IEEE-383.
