Ultra-high-voltage Transformer Testing FacilityIt is a digital testing facility with capacity of 3,600kV that can test high-voltage, large-capacity

transformers. Main equipment include a tester for impulse withstand voltage that measures status

of insulation, a tester for power frequency withstand voltage, and a state-of-the-art precision system

to measure voltage loss.

Ultra-high-voltage Breaker Testing Facility■ Voltage Withstand Tester of Insulation for Breakers (600kV, 750kV and 1,000kV)The facility determines the status of insulation with a partial discharge (PD) test and a voltage

withstand test for insulation materials used in breakers.

■ Impact TesterThe facility can test impacts ranging between 200kV and 2,000kV to determine the level of safety of

GIS products against lightening and high voltage.

■ Voltage Withstand TesterThe facility verifies insulating strength of a breaker (400~1,200kV) and has two types: fixed type for

a factory and portable type that can conduct an on-site test.

Insulating strength can be tested at a factory and upon completing installation on site.

Clean RoomParticles destroy the insulation strength of a breaker while assembling the components, and

therefore the assembly takes place in a Clean Room with high-tech facility. The Clean Room is

managed in accordance with the supreme standard of leading breaker companies and the Clean

Room class at Hyosung is maintained at the identical level to that of advanced countries.

Hyosung has specialized production facilities including mold factory that produces various molds in annual amount of 20,000t, a cannery that produces structures under thorough inspection from surface treatment to coating, and Clean Room with perfect dust proof facility. It also has an ultra-high-pressure laboratory equipped with a device to generate maximum voltage of 3.6 million and a pressure test device of 1.2 million voltage to conduct performance test and commissioning for all the products.
