How to choose outdoor drag chain Ethernet cable? Don’t make random purchases and rework anymore
Do colleagues who work in outdoor automation equipment, port machinery, cranes, outdoor manipulators, and mobile monitoring often encounter the trouble of network cables breaking shortly after use?
The root cause of most problems, such as cracked outer skin, bent core wires, frequent disconnections during thunderstorms, and fluctuating signal quality, is the wrong selection of network cables.
Many people try to save time by mixing three types of lines, all of which are pitfalls:
1.Indoor drag chain Ethernet cable: without sun protection and UV resistance, the outer skin will directly powder and rot after being outdoors for six months;
2.Ordinary outdoor fixed Ethernet cable: The interior is made of solid hard copper, which can only be used to fix the wiring. After being placed in a drag chain and bent back and forth a few times, the internal copper wire will break;
3.Unshielded/Single layer Shielded Ethernet Cable: Outdoor motors, frequency converters, and high-voltage wires have significant interference, causing the network to freeze and disconnect whenever there is interference.
The outer sheath is the key to the durability of outdoor ethernet cables, and the material should be selected according to the environment
1.Most outdoor factory universal: weather resistant Cabo Ethernet PUR
It comes with sun protection, waterproof, wear-resistant, and is not afraid of slight oil stains. It is not easy to crack or peel after repeated bending, and can be used for outdoor CNC equipment and exterior wall mobile monitoring.
2.Northern sub zero cold regions: Cold resistant TPU/PUR outer skin
Ordinary plastic will become hard and brittle at low temperatures, and will crack when bent. For low-temperature special models, even at minus 40 degrees Celsius, the outer sheath will slightly harden, but it is not easy to crack.
3.Outdoor site with high oil pollution on machine tools: Oil resistant PUR Ethernet cable
Cutting fluid and lubricating oil will not corrode the outer skin, and are not easily damaged in long-term oily environments.
Outdoor mobile ethernet cable, be sure to choose S/FTP double-layer shielding (same structure as CAT7)
There are many outdoor interference sources, and single-layer shielding cannot withstand them at all. Each of the four sets of wires in the inner layer is wrapped in aluminum foil to avoid mutual interference within the network cables; The outer layer of tinned copper braided mesh blocks external motors and strong electrical interference. Compared to ordinary bare copper, tin plated copper is moisture-proof and rust proof, and has a longer service life in humid and foggy environments near the sea. Abandon unshielded and single shielded network cables directly for outdoor drag chains.
How to choose cabo ethernet cat6a e cabo ethernet cat7?
CAT6A double-layer shielding cable: the first choice for cost-effectiveness, with a bandwidth of 500MHz, stable operation on 10 Gigabit networks, compatible with EtherCAT and industrial Ethernet, sufficient for ordinary outdoor mobile devices and monitoring.
CAT7 double-layer shielding cable: dedicated for harsh working conditions, 600MHz high bandwidth, FMPE insulation, and stronger shielding effect, suitable for long-distance drag chains, multi device synchronous communication, strong electromagnetic interference in factory areas, and 10 gigabit backbone lines.
What grade of cabo Ethernet flexível should be selected for outdoor use?
1.Bending life: Ordinary equipment has a reciprocating motion of ≥ 5 million times; High speed frequent mobile devices ≥ 10 million times;
2.Twisting performance: The rotating cantilever equipment requires ≥ 500000 twists (± 180 °, with a single stroke of 600mm or more);
3.Minimum bending radius: In order to ensure that the transmission rate of the network cable is not attenuated, it should not be less than 14 times the outer diameter of the cable in motion, and is suitable for narrow drag chain spaces;
Summary above
Do not mix indoor network cables, do not use fixed hard wires, prioritize double-layer shielded Ethernet cables, identify PUR for the outer sheath, match materials for working conditions, and focus on checking the bending life.
