How to choose a suitable surge protector factory?
Mar 04, 2024With the continuous development of social science and technology, surge protectors (SPD) have become an indispensable electrical protection component in modern buildings and important facilities. So, how to choose a surge protector factory?
1. Regarding product questions:
The selection of a surge protector mainly depends on the following parameters:
Maximum continuous operating voltage (Uc): The maximum effective AC power frequency voltage or DC voltage that is allowed to be permanently applied to the surge protector. Its value is equal to the rated voltage.
Maximum impulse current (Iimp): Usually the impulse current test with 10/350us waveform is used, which belongs to the Class I classification test, which means that the SPD can withstand a maximum current impulse.
Maximum discharge current (Imax): According to the 8/20us waveform test, the test belongs to the Level II classification test. The maximum discharge current that can be withstood through the action load test.
Protection voltage Up: The product should be marked with protection voltage Up. Up should be less than the measurement limit voltage and at the same time less than the impulse withstand voltage value of the equipment.
2. Inspect factory strength and quality management system:
Anhui Jinli's products are widely used in basic industries and emerging industries such as electric power, new energy, railways, rail transit, industrial automation, metallurgy, and chemical industry. Complete certifications, worry-free after-sales, and both production capacity and the company's internal management system are at the forefront of the industry.
Production strength: The company's R&D, production, and office space covers an area of 56,000 square meters, including 400 square meters of testing area.
Testing capabilities: It has all the testing capabilities required by national and international standards such as GB/T18802.11/21/31, IEC61643-11/21/31, UL1449, etc., and has passed on-site testing by UL witness laboratories in the United States and TÜV Rheinland manufacturers. Laboratory certification.
Product certification: EU RoHS certification, Ministry of Industry and Information Technology Tel certification, railway industry CRCC certification, EU CE certification, US UL certification, and German TÜV certification.
