Outdoor Cable: Three Threats, Three Answers
Quick answer / TL;DR: Short answer: choose UV-stable jacket for exposed routes, flooded or blocked construction for wet and buried runs, and armour or conduit where rodents or impact are risks. Seal building entries, add drip loops and earth metallic armour. Copper distance limits apply outdoors exactly as indoors.
One category, three axes: shielding, conductor and jacket create the SKU.Cable outdoors faces sunlight, water and mechanical damage. Each threat has a specific construction answer, and indoor cable answers none of them.
Most outdoor failures are environmental rather than electrical.
Threat and Construction
| Threat | Answer | Failure if ignored |
|---|
| Sun | UV-stable jacket | Jacket cracks |
| Water | Flooded core | Corrosion and loss |
| Rodents | Armour or conduit | Chewed conductors |
| Surge | Protection device | Damaged ports |
The surge row applies to any run leaving a building: a long outdoor cable is an aerial for induced voltage.
Installation Practice
- Conduit at entries
- Drip loop outside the wall
- Seal penetrations
- Earth armour
- Test after installation
The drip loop is a two-minute detail that stops water tracking into the wall.
Real-World Applications
A garden office uses flooded cable in conduit with surge protection at the house end. A camera on a pole needs the same plus a protected switch port.

Practical Notes
Record attenuation of outdoor spans at installation. Moisture ingress shows as a slow rise.

Frequently Asked Questions
Can indoor cable go outside?
No. It fails within a season.
Do I need conduit?
At entries and wherever disturbed.
Is armour waterproof?
No. It resists impact and rodents.
Does distance change outdoors?
No. Same 100 m limit.
