Epoxy Insulator Quality

Epoxy insulators by GIPRO are tested with ghiest standards to guarantee best quality possible.

Tested and approved insulators, plugs, medium voltage bushings and secondary bushings

At GIPRO we can guarantee faultless delivery, test documentation and insulator durability.

So that you only receive insulators and bushings which meet our exacting quality standards, we use a wide range of state-of-the-art testing equipment:

  • Partial discharge testing: 1 device for up to 110 kV
  • Partial discharge testing: 1 device for up to 200 kV
  • Electrical testing
  • X-ray testing
    (RT1, RT2-inspectors acc. EN ISO 9712)
  • Helium leakage detection systems
    (LT1, LT2-inspectors acc. EN ISO 9712)
  • Climatic testing chambers for temperature tests
    (-70° to +180° C)
  • Pressure testing
  • Burst testing
  • DSC analysis (e.g. to determine glass transition temperatures)
  • Determination of filler content

GIPRO has many partners in the world of scientific and technological research, in both the public and private sectors. Among others, we have partnerships with Graz University of Technology (www.tugraz.at), Montanuniversitaet Leoben (www.unileoben.ac.at), the Polymer Competence Center Leoben  (www.pccl.at), the Austrian Casting Institute  (www.ogi.at) and the Aerospace & Advanced Composites research centre in Seibersdorf

Additionally we work with the engineers from EPS in UK
 (www.eps-uk.co.uk) and the company StresCon in Germany (www.strescon.de).

Electrical Testing and Gas-tightness

PD-Testing of bushings and insulators

Electrical Testing of Insulators

Insulators and bushings are tested on their PD-levels (partial discharge) up to 200 kV.

Gas-tightness measurement of bushings

Helium leakage detection

Bushings are tested on their gas-tightness. GIPRO has skilled LT1, LT2-inspectors acc. EN ISO 9712.

X-ray Testing and Climate chamber

Quality control of insulators by GIPRO through X-Ray-Testing

X-Ray Testing of Insulators

Insulators are checked in the X-ray chamber regarding their matrix homogeneity. GIPRO has skilled RT1, RT2-inspectors acc. EN ISO 9712.

Epoxy insultors have to be able to endure the highest temperatures.

Temperature Testing

At GIPRO insulators could be checked within a temperature range from -70° to +180° C.

Chemical Analysis and dimensional inspection

Chemical analysis of insulators by GIRPO

Differential Scanning Calorimetry Anaylsis

With the DSC-Analysis (Differential Scanning Calorimetry) the glass transition temperature of insulators could be tested.

controlling the dimensions of insulators to ensure best work

Dimensional Inspection of Insulators

Exact dimensional inspection of epoxy insulators is available with high-precision and modern instruments.
