Externally-oriented cables are specifically designed to endure the harsh conditions found outdoors. The cable’s outer layer is required to shield the cable from external forces like mechanical damage, water, extremes in temperatures, insect or rodent attacks, UV radiation from sunlight, and ozone in the atmosphere.
Many kinds of outdoor-friendly cables are suitable for use, provided they are shielded from direct sunlight or other external factors. The protection can be achieved by placing the cables inside conduits made of metal or plastic or directly buried using steel armouring of wire.
In the case of wires, the type of insulation used.
Electrical cables usually comprise three insulation types: PVC, polyethylene, and cross-linked polyethylene. PVC is considered to be the more commonly used type of insulation as it is strong as well as resistant to sun as well as moisture.
Indeed, PVC does not have the same flexibility as polyethene, making it unsuitable for colder weather. Polyethene insulation is a more flexible choice with a higher degree of flexibility and is also resistant to chemicals and water. Polyethene cross-linked is the least expensive insulation type; however, it is also extremely durable and can endure extreme temperatures.
When selecting an electrical cable intended for outdoor use, it is essential to consider the surroundings where it will be utilized. For instance, when the cable is exposed to sunlight, it’s crucial to select the cable with UV-resistant insulation. Select a cable with waterproof insulation if the cable will be utilized in a humid, humid area.
What cable is suitable for outdoor use?
When selecting an electrical cable for outdoor use, it is essential to consider factors such as weather resistance, durability, and protection against moisture and UV radiation. Here are some cables that are suitable for outdoor use:
Direct Burial Cable: This type of cable is designed to be buried underground and is protected against moisture, water, and UV radiation.
Outdoor Ethernet Cable: Ethernet cables designed for outdoor use are typically constructed with a weather-resistant jacket and insulation that protects against moisture, water, and UV radiation.
Coaxial Cable: Coaxial cables designed for outdoor use are typically used for cable TV, satellite TV, and internet connections. They have a durable, weather-resistant jacket that protects against moisture, water, and UV radiation.
Fiber Optic Cable: Fiber optic cables are often used for outdoor applications due to their high bandwidth and immunity to interference. They are typically installed in conduits or buried underground, and a water-resistant jacket protects the cables.
When selecting an outdoor cable, consider the specific environmental factors the cable will be exposed to, such as temperature, moisture, and UV radiation. It’s also important to follow any local codes or regulations that may dictate the type of cable that can be used for outdoor installations.
Final Thoughts
In conclusion, choosing the right cable for outdoor use is crucial to ensure the safety and reliability of your electrical or telecommunications system. Factors such as temperature range, weather resistance, UV protection, and mechanical strength must be considered when selecting an outdoor cable. It’s important to understand the types of cables available and their intended use before purchasing. By following the guidelines in this article and consulting with a professional, you can select a cable that meets your needs and ensures optimal performance in outdoor conditions.
