The application of Ethernet cables is becoming increasingly widespread, and they are often used in outdoor environments in practical use. In the previous chapter, we discussed that outdoor network cable can choose PE waterproof cables or Ethernet-кабели из полиуретана. PVC network cables are not suitable for outdoor use because they cannot resist ultraviolet rays. Due to the high price of PUR Ethernet cables, most people choose cheaper PE Ethernet cable.PE waterproof Ethernet cables have an additional PE outer sheath, which can be waterproof and UV resistant. However, if used in outdoor environments with exposure to sunlight, rain, low temperatures, frequent movement, and oil stains, PE waterproof Ethernet cable can no longer meet the requirements. In this case, it is strongly recommended to use PUR Ethernet cables.
In what scenarios should outdoor PE Ethernet cables be used？
The network cable is installed in a fixed outdoor environment: along the wall, buried underground, suspended in the ceiling, and not touched for a long time, such as household monitoring in ordinary residential areas, with weak sunlight, no oil stains, and not moving. The budget is limited, as long as it can last for 2-3 years.
In this case, choose black PE sheathed CAT5E Ethernet cable или CAT6A outdoor network cable (with waterproof and UV resistant)
Strongly recommend choosing PUR наружный Ethernet-кабель for occasions
1.Long term exposure to sunlight, rain, and large temperature differences on the top/exterior walls of the monitoring pole
2.The cable ethernet outdoor needs to be frequently bent, dragged, and dragged along the drag chain (such as door machines, gimbals, and mobile devices)
3.Near oil stains, machines outside the computer room, and industrial environments
4.Coastal/high humidity/salt spray areas
5.I hope the wiring can last for 5-10 years without replacement
Ethernet-кабель из полиуретана is the best Ethernet cable for outdoor use
1. Super aging resistance and sun exposure resistance
Ordinary PVC network cables may experience cracking and powdering of the outer layer after 1-2 years of outdoor use;
PUR Ethernet cable is UV resistant and does not harden or crack under direct sunlight all year round. It can be used outdoors for 8-10 years without aging.
2. Resistant to high and low temperatures, stable throughout the four seasons
Applicable temperature: -40 ℃ to+85 ℃
It does not freeze, harden, or crack in winter, and does not melt or deform in high temperatures in summer. It can be used for both exposure to sunlight in the south and cold winters in the north.
3. Waterproof, moisture resistant, and hydrolysis resistant
Polyether PUR material, moisture-proof, waterproof, resistant to high humidity and mold;
Coastal salt spray, outdoor rain, and damp wall corners make it more durable than ordinary outdoor network cables.
4. Bending resistance, tensile strength, and resistance to core breakage
PUR Ethernet cable outer skin is soft and tough, not hard skin:
Suitable for monitoring pan tilt zoom, pole turning, and outdoor wiring bending;
Wind shaking and slight pulling are not easy to break wires or cores, reducing network disconnections.
Suitable for use in outdoor mobile environments with large equipment, such as in outdoor drag chains as кабель Ethernet для буксируемой цепи.
5. Oil and corrosion resistance
Not afraid of engine oil, dust, and slight acid-base corrosion;
Because PUR material is much more expensive than PVC and PE materials, PUR network cables are more expensive, but have a longer outdoor lifespan, stability, and less maintenance. So choose according to your needs.
