ZHEJIANG HAIVO ELECTRICAL CO., LTD., a leading Chinese manufacturer of medium and high-voltage electrical equipment, today announced that its self-developed SF-Type Fuse Link has successfully passed rigorous type testing at the National Electrical Product Quality Inspection and Testing Center and has been awarded the authoritative certification certificate. The test data fully complies with the relevant International Electrotechnical Commission (IEC) standards, with several key performance indicators far exceeding the industry average, highlighting Haivo's exceptional product development and quality control capabilities.
The type testing conducted a comprehensive and stringent evaluation of the fuse link's core performance. Haivo's SF-Type Fuse Link performed outstandingly in the following critical tests:
Pre-arcing Time-Current Characteristic: The characteristic curve precisely matches IEC standard requirements, ensuring perfect selective coordination with upstream and downstream protection devices for accurate fault isolation.
Circuit Resistance: The measured resistance value is extremely low and stable, meaning lower energy consumption, reduced heat generation, and higher energy efficiency.
Static Mechanical Performance of Fuse Link: Demonstrated extremely high mechanical strength and toughness, sufficient to withstand various mechanical stresses during transportation, installation, and operation, ensuring long-term reliability.
Temperature-Rise Test: Under rated current, the temperature rise was significantly lower than the standard limit, proving its excellent heat dissipation capability and long-term overload capacity, greatly enhancing the safety margin.
"We are extremely proud of the performance of this SF-Type Fuse Link," said the Technical Director of Haivo Electrical. "Every test result that exceeds the standards stems from our relentless pursuit of materials science, precision manufacturing, and attention to detail. This is not just a certificate; it is the fulfillment of our promise to customers to 'deliver highly reliable products.' It can provide a higher level of protection for your power system."
This successful certification further enriches Haivo Electrical's fuse product portfolio and solidifies its position as a trusted, high-quality supplier in the global power industry.
