How to Protect an Outdoor Ethernet Cable

Updated: Jul 23

There are many farms in our area, which produce vegetables and fruits all year round, and some of them have installed video surveillance to facilitate the management of plants.


The local outdoor temperature in summer is above 40°C, and in winter it is often below 0°C. In this environment, the CCTV video surveillance system has been operating at high and low temperatures for a long time.


How to Protect an Outdoor Ethernet Cable

Reducing the Risk of Lightning Strikes and Storm Damage

1. Weatherproof your Ethernet cable's connector box.

Making your connector box weatherproof can both minimize the likelihood of strikes and the extent of damage withstood during stormy weather. Replace the cover plate with an outer plating and apply a silicone seal to the outer edges to make it weatherproof and resistant to storm damage.

Applying a silicone seal can also help your connector box keep insects and other pests out.


2. Pick a waterproof cable to minimize damage during storms.

Waterproof cables are more likely to withstand power surges and damage during stormy weather. Although most outdoor cables are waterproof, some may not be—make sure your Ethernet cable has a waterproof coating before installing it.


3. Choose an Ethernet cable that can withstand surges of at least 6 kV.

Although you may not be able to control lightning strikes, you can control whether sudden electrical surges damage your cord. To prevent damage during storms or power surges, choose a network cable and connector that can handle at least 6 kilovolts (kV).


Cables and connectors that can handle 6 kV may still withstand damage from surges but to a lesser extent.


4. Look for polyethylene cables that can withstand extreme temperatures.

If you'll be running your Ethernet cable in harsh weather, choose one with a polyethylene jacket. Polyethylene cables
