Shandong Taikai High-Voltage Switchgear Co., Ltd. 1100kV Combination Electrical Apparatus Passes All Type Tests

On March 21, 2017, the 1100kV combination electric appliance manufactured by Shandong Taikai High Voltage Switchgear Co., Ltd. passed 20 electric life tests at the Xi'an High Voltage Electrical Apparatus Research Institute, marking that the product successfully completed all type tests.

 

Shandong Taikai 1100kV combination electric appliance is a company based on the introduction of Japan Mitsubishi rated short-circuit breaking current 50kA arc extinguishing chamber, designed and developed 63kA, with independent research and development operating power 33000 co hydraulic spring operating mechanism, which lasted 10 months to complete a full set Type test of UHV switchgear. The rated current of the product is 8000A, the rated current of the busbar is 10000A, and the mechanical life is 10,000 times. Among them, the circuit breaker in the same industry for the first time through the electrical life of 20 times and 30 positive and negative polarity insulation verification test, reached the international advanced level; isolation switch bus switching current 2520A, higher than domestic and international standards 1600A The grounding switch opens and closes the electromagnetic induction current 500A, opens and closes the static induction current 50A, exceeds the IEC standard B level level.

 

The successful passing of the test demonstrated the development capability of Thai Kai in the UHV field, improved the popularity of the Thai Kai brand, and enhanced the competitiveness of Thai Kai products in the domestic and foreign markets.
