Quality Control Plan
Inspection and tests of Gital busduct products are carried out in
accordance with IEC-60439-1&2 standards.
In addition to routine test equipments, some selected
type test equipments, essential for design purposes,
are also available at our facilities.
Domestic and overseas laboratories and test centers are used for
other type tests.
Inspections and tests can generally be classified as:
A- Inspection on incoming materials and parts
Inspection and/or tests of incoming materials and parts are carried
out based on manufacturers certificates and according to international
standards, prior to production.
B- On-going production inspections
Every production station is inspected according to procedures specified
by our quality control department.
These includes inspections and tests on each batch of manufactured
parts at metal shop, conductor shop, paint shop and assembly shop.
C- Finished products
The finished busducts are tested in accordance with IEC-60439-1&2
in two major categories:
1- Type tests
These tests are carried out prior to mass production on a sample
- Temperature rise limits
- Dielectric properties
- Short circuit strength
- Protective circuit continuity
- Resistance and reactance
- Clearance, creepage and gaps
- Mechanical operation
- Structural strength
- Degree of protectio
Note: Type tests maybe repeated upon customers
Routine tests are carried out on each product according to IEC and
can be summarized as below:
- Visual inspections
- Dimensional checks
- Phase sequence tests and earth continuity
- DC resistance tests
- High voltage withstand tests
Customers may be present during all above mentioned
routine tests and inspections.
