The main difference between indoor and outdoor cables for network cables and power cables lies in the material and thickness of the outer sheath. The outer sheath of outdoor cables is generally made of PE (polyethylene) or PVC (polyvinyl chloride), which has the characteristics of waterproof, anti-ultraviolet, anti-corrosion, tensile, and compressive resistance, and can adapt to harsh environmental conditions. The outer sheath of indoor cables is generally made of PVC or LSZH (low smoke zero halogen), which has the characteristics of flame retardant, low toxicity, low smoke, etc., and can ensure the safety and environmental protection of the indoors.

The outer sheath of outdoor cables is generally much thicker than that of indoor cables, and some outdoor cables also have two layers of outer sheath to increase the protection performance. The outer sheath of indoor cables is generally thinner, to maintain the flexibility and ease of wiring of the cables.

The application occasions of indoor and outdoor cables are also different. Outdoor cables are mainly used for outdoor network wiring, power transmission, communication signals, etc., and need to withstand the influence of natural factors such as wind, rain, sun, and frost. Indoor cables are mainly used for indoor network wiring, power supply, household appliances, etc., and need to meet the indoor standards of flame retardant, low smoke, etc.
