Lightning Arrester for CCTV 21m Tower: BR Series Protection Solution

# Lightning Arrester for CCTV 21m Tower: BR Series Protection Solution

## Understanding the Need for Lightning Protection

When installing CCTV systems on 21-meter towers, lightning protection becomes a critical consideration. These tall structures are particularly vulnerable to lightning strikes, which can cause catastrophic damage to sensitive surveillance equipment. The BR Series lightning arrester offers a reliable solution specifically designed for such applications.

## Key Features of BR Series Lightning Arresters

The BR Series lightning arresters provide several advantages for CCTV tower installations:

– High surge current capacity (up to 100kA)
– Fast response time (<25 nanoseconds)
– Low residual voltage
– Weather-resistant housing
– Easy installation and maintenance

## Installation Considerations for 21m Towers

Proper installation of lightning arresters on 21m CCTV towers requires careful planning:

1. The arrester should be mounted at the highest point of the tower
2. Down conductors must follow the shortest, straightest path to ground
3. Grounding resistance should be less than 10 ohms
4. All metallic components should be properly bonded

## Technical Specifications
