Outdoor wires and cables face much more complex environments than indoors, and several key points need to be remembered.
Firstly, do not directly use ordinary indoor wires outdoors for long-term use. The outer skin of ordinary wires cannot withstand long-term exposure to wind, sun, and rain, and will crack after a few months of use. Outdoor wires should be selected in a style that can adapt to the outdoor environment, withstand UV rays and moisture, and is not easily damaged.
When pulling overhead power lines, do not pull the wires too tightly. In summer, the wires will slightly expand and elongate during high temperatures, and in winter, they will shrink during low temperatures. If the wires are pulled too tightly, the cores can easily break during low temperature weather. The buried wires should be covered with a layer of soft soil and a hard object. Do not let sharp stones directly press on the wires to avoid puncturing the outer skin.
Outdoor wires should also avoid low-lying areas that are prone to water accumulation. If they are soaked in water for a long time, the gaps in the outer layer will slowly seep in, affecting the internal core of the wire. Regularly walk around the outdoor wires to check for any tree branches scratching the outer skin or heavy objects pressing on the wires. Timely handling can make the outdoor wires last longer.
