Mechanical testing

EGU – HV Laboratory a.s. EGU – HV Laboratory a.s. has been performing mechanical testing of insulators for many years. Due to today’s energy sector demand of a higher transmission capacity insulator length and mechanical ratings are rising up.
An installation of a new professional Tensile Testing Machine 600 kN have been completed. The machine fulfi lls criteria given in ISO 7500-1 and other relevant DIN and ISO international standards.
Technical parameters:
- Maximum testing load: 600 kN
- Testing frame length: 5 000 mm
- Testing frame width: 500 mm
- Maximum testing speed: 150 mm/min
- Position resolution: 2 μm
- Accuracy: < 1%
Other parameters:
- Horizontal position installation
- Fully PC controlled
- Fully variable loading parameters and profi les
- Special software for data acquisition and test results visualization
Testing:
- Testing of test objects in length up to 5 000 mm
- Failing load testing of polymeric / glass / porcelain insulators
- Long-term (96 h) testing of insulators
- Testing acc. to IEC 61109, IEC 60383-1 etc. and customer requirements
- Conductors and fi ttings mechanical testing
