So that’s how I understand how to tell if extension cord is for outdoor use.

An indoor extension cord is generally laid through the protection tube, not affected by bad weather, and the line is also less, the protection layer (绝缘层) only one layer.

And outdoor extension cord to withstand the test of climate and temperature, more protective layer, more lines, laying difficulties (can wear protective tube laying, can be laid directly along the cable trench, can be laid along the cable well, laid along the bridge, along the steel cable overhead laying, can also be laid directly buried, 等等). In order to prevent lightning interference but also for lightning grounding protection.
There are two types of extension cords from extension cord application scenarios: outdoor extension cord and indoor extension cord. As the name implies, the outdoor extension cord is the cable used outdoor. Indoor extension cords are mainly used indoors; the biggest difference between outdoor extension cords and indoor extension cords is the skin; outdoor extension cords have a double skin, while indoor extension cords have only one skin.

Outdoor extension cord skin than indoor extension cord skin is much stronger, and also added an extra layer of PE waterproof layer, which can well prevent the extension cord inside water seepage, strong skin in the process of outdoor alignment, can resist tensile and compressive, not easy to destroy the skin, copper core.

Indoor network extension cord to a greater extent to maintain the flexibility of the indoor alignment, in the case of alignment through the tube, be careful to protect the skin of the indoor extension cord, especially in the case of pulling the line, not too hard, it is easy to pull bad core.
If the better quality extension cord, such as all copper, oxygen-free copper extension cord can also be used for a long time, but there may be a bad situation, plus the wind and rain, wind and sunlight exposure and increase the possibility of causing damage to the epidermis of extension cord, and these are the causes of extension cord damage.
The extension cord is placed outdoors and needs to resist rain and hot sun; if the skin is not good, then the skin is very easy to damage the extension cord conductor can not be used.

An outdoor extension cord can also be routed not only outdoors but also indoors; in case the extension cord has to pass through the wall, the tensile strength of the outdoor cord can make the extension cord less damaged. In particular, in some indoor areas where the moisture is too heavy, it is easy to wet areas can use an outdoor water resistance line.

例如, there is a special period of time in the south, 那是, back to the south, 那是, humid days, the most easily wet, this is suitable for choosing outdoor network cable, in the price of outdoor water resistance cable is not much higher than the indoor line, but in the function and service life are better than the indoor line. Outdoor wiring environment is often more difficult than indoor wiring. It is generally recommended that indoor network cable should not be used in outdoor cabling.
