Type Tests on GSS Earth Wire
All the type tests are performed on a single strand of sampled length.
- Breaking load measurement,
- Measurement of elongation on breaking due to ultimate tensile load,
- Measurement of electrical 3 resistance of the strand,
- Wrapping test,
- Galvanizing test,
- Torsion test.
Routine Tests GSS Earth Wire
- Checking for joints on the wires,
- Checking for any cuts in the wire or wire strand,
- Checking the correctness of the strands,
- Checking of the drums and tallying with approved drum drawing or specification.
Acceptance Tests of GSS Earth Wire
- Visual checks for joints etc. and that can be done by rewinding one or two drums per lot,
- Measurement of diameter of steel strands,
- Verification of lay ratio .
- Breaking load test on the individual strand as well as on the complete earth wire,
- Elongation test on the individual strand,
- Wrapping test for each strand,
- Measurement of DC resistance of each sampled steel strand,
- Galvanizing test on steel strand,
- Chemical analysis of the steel strand.
