Lightning arrester for telecom towers: How to choose a manufacturer

Image
  A lightning strike can destroy a telecom tower in seconds. Antennas, cables, and other gear can get fried. And the repair bill? Usually not small. So picking a lightning arrester is a big call. It has to fit the site, and the rest of the protection setup needs careful planning too. Going with the cheapest option tells you almost nothing about whether it’ll actually work. What should you check before buying a lightning arrester? Start with the tower. How tall is it? What area needs covering? Where will the arrester go? Those answers help narrow down which model could work. Review the product specs, and ask for test reports. Also check the manufacturer's technical documentation, applicable standard compliance, warranty and after-sales support. For telecom towers, confirm that the proposed model suits the site-specific lightning protection design. A good lightning arrester manufacturer should explain its products clearly. If you can’t find what you need, ask before you order. It’s ...

AC vs DC surge protection devices: Which is right for your application

Image
  A voltage spike doesn’t warn you. It hits fast. Electrical equipment, including control panels, computers, solar inverters, and other sensitive devices, can be damaged in seconds. Some items keep running for a bit, then fail. Repair and replacement costs add up fast. AC and DC systems both need protection. But they don’t need the same kind. Let us dive into the differences and how to choose the right one. What is the difference between AC and DC? AC stands for alternating current. The current direction flips back and forth repeatedly. Most homes, offices, factories, and commercial buildings run on AC. DC stands for direct current. It flows in one direction only. Solar panels and battery systems use DC. Both AC and DC systems can experience voltage spikes caused by lightning or electrical switching. However, their protection needs differ. A surge protection device (SPD) must match the power supply type and voltage rating. Never use an AC model on a DC system unless the product sp...
