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...

Lightning arrester vs surge arrester: which one do you need for better electrical protection

Image
Lightning can damage a building and the electrical equipment inside it. These risks need different types of protection. An ESE lightning arrester is part of an external lightning protection system. A surge arrester, or SPD, protects electrical circuits and connected equipment from transient overvoltage.   Some buildings may need both. Feature ESE lightning arrester Surge arrester / SPD Main purpose Protects the structure from direct lightning strikes Protects electrical circuits and connected equipment from transient overvoltage Installation Outside the building Inside the electrical distribution system Protection path Down conductor and earthing system Diverts surge current through the SPD to the earthing system Typical location Roof, mast or other suitable high point Main or sub-distribution boards Protects ...

How can a type 2 surge protection device protect your electrical equipment from surges

Image
  A voltage surge can last for only a few microseconds, yet it can damage control panels, electronic equipment and other connected loads. Lightning-induced disturbances and switching operations can create these sudden voltage rises. A surge protection device spd helps limit that voltage and reduce the stress reaching downstream equipment.   A Type 2 surge protection device protects electrical equipment by limiting transient voltage and diverting surge current away from downstream circuits. It is commonly installed at distribution boards to reduce the surge energy reaching connected equipment such as control panels, automation systems and electronic devices. What is a Type 2 surge protection device? A surge protection device type 2 is installed in low-voltage distribution systems to limit transient overvoltage. It is commonly fitted at a distribution board after the incoming protection, protecting circuits and equipment further down the installation.   Axis offers Ty...
