Why Does a Tinned Annealed Copper Wire Perform Well In Wet Environments?
Cables or wires are made of metallic substances like copper. Copper is one of the most sought after materials for making electrical and power cables because of it’s good conductivity and work ability. Copper has a low corrosivity level however, when it is exposed to conditions that promote corrosion, it may suffer huge degradation thereby compromising the longevity and durability of the cable. A cable like Instrumentation Cable Multi-Conductor Overall Shield 600V VW-1 ULTROL 60+ is enhanced by using a tin coating process on the copper material. This is a tinned, soft annealed copper wire used in nuclear power generating plants and other critical areas where there may be risk of heat and electrostatic exposure to the wires. Because this wire is tinned, it works well in wet areas.
Corrosion affects cable performance
Due to weather ability issues, cables may degrade in strength and quality after insulation thereby presenting risks to the premises or machinery where they are installed. Cable manufacturers try to meet the requirements for producing cables for specific applications. The manufacturers classify the wires to make sure that they meet the standards. Again, the cables are marked to make sure that inspectors and installers do not find it difficult to identify them.
Wetness increases chances of corrosion
One of the factors that contribute to rusting or corrosion is wetness or dampness. For corrosion to occur, there has to be oxidation of the substrate or metal. Water gives out the oxygen ions that are used up during the process of corrosion to form oxides. In wet areas, if you are going to use direct burial cables, they should have features that protect them from corroding.
The use of tin coating on copper wires designed or used for direct burial applications has a significant importance. Although the cable may be insulated and jacketed to protect it from moisture, it also needs to be anti-corrosive.
Tin does not corrode easily
The tin material that is applied on the copper wire makes it not corrode easily. Tin is among the materials that have low levels of corrosivity meaning that they will not oxidize easily even in wet conditions to corrode. In order to improve the performance of the copper wire, it is tinned to further prevent the effect of corrosion.
The Instrumentation Cable Multi-Conductor Overall Shield 600V VW-1 ULTROL 60+can perform well in moist areas because it is made of tinned copper wire. In addition to preventing corrosion, tin also helps in enhancing the work ability of the wire. For example, it ensures that installers can easily solder the wire because tin has excellent solder ability properties. The use of tin coating on the instrumentation cable also improves the conductivity of the wire.
