When choosing a surge protection device for lightning protection in anti-induction engineering, it's essential to select a technologically advanced manufacturer that provides comprehensive product information. This includes detailed specifications, technical parameters, origin, standard certifications, and sales licenses. Here are key factors to consider when evaluating surge protectors: (1) User-Friendly Design: The ideal surge protector should be compact, easy to install, and fit into existing spaces without requiring major modifications. A simple and intuitive installation process is crucial for user satisfaction. (2) Response Time: The surge protector must react faster than the surge itself. Its response time should be in the nanosecond range to ensure effective protection. Bell Core Labs conducted extensive research on this, and modern surge protectors like the Qian'an model meet these high standards. (3) Maximum Current Handling: This refers to the peak current the surge protector can handle at once. For example, an 80 kA surge protector installed at a building’s branch line power box is sufficient for most applications. However, in high-risk areas with frequent lightning strikes, larger models (up to 400 kA) are recommended for the main AC distribution box. (4) Energy Absorption Capacity: Measured in joules, the higher the value, the longer the lifespan of the surge protector. This feature ensures the device remains effective over time under repeated surges. (5) Clamping Voltage: The ability to limit overvoltage to a safe level is critical. According to the GA173-1998 standard, the clamping voltage for computer surge protectors in a 220/380 V system should not exceed 2000 volts. This protects sensitive electronics from damage. (6) Size and Internal Inductance: Smaller surge protectors have lower internal inductance, which improves their performance. They can be placed closer to the distribution box—ideally within 15 cm—to reduce the negative impact of connection inductance. Large devices may not fit in tight electrical spaces. (7) Compliance with Standards: Surge protectors should comply with international standards such as UL1449, ANSI/IEEE, NEMA, and IEC. In China, they must also meet GA173-1998 requirements and obtain a sales license before being sold. (8) Product Reliability: Checking the manufacturer’s customer list and history helps assess their reputation and product quality. A reliable company will have a proven track record of delivering consistent performance. (9) Warranty and Support: A long warranty period indicates the manufacturer’s confidence in the product. Quick and free service after purchase is also an important consideration for users. Choosing a data line protector involves considering various factors, including connector types, voltage levels, and application-specific needs. Here are three key points to guide your decision: (1) Transmission Voltage: Determine the exact transmission voltage of the device you're protecting. A good surge protector should clamp overvoltage close to the rated voltage of the equipment. Check your device manual or use a voltmeter if unsure. (2) Connector Type: There are hundreds of connector types used in data lines. Common ones include coaxial, twin-axial, RJ11, RJ45, and USB. If your connector isn’t listed, consult with the manufacturer for custom solutions. (3) Data Transfer Speed: The speed of data transfer, measured in Mbps or MHz, determines compatibility. A protector designed for 10 MHz may not work for a 100 MHz application. Always check your device manual for the required speed and specify it in every order.
