In electrical and electronic goods, there are many different types of wires and cables that play important roles in the transmission of information or power from one place to another. There are various types of cables that are used and play a vital role in any form of connection, such as industrial cable, shielded, profibus cables, fibre optic cables and electrical power cable.
Many manufacturers have gained a great deal of expertise in manufacturing them to the highest standards, in aim to reach optimum performance and safety. Shielded cable is often required for certain sectors of the industry, especially power, telecommunications and railway, whereby the cables are exposed to a rough environment, which requires them to be robust.
In industries that require large amounts of cable use, there will be a range of different types of cables that are used for certain purposes, the most common being rubber cables, fibre optical, instrumentation, control and LAN, amongst many others. Many of the leading manufacturers of these types of cables offer custom made cables specific to customer needs.
Different types of cables are used for different purposes. There are four different types of basic physical construction of cables. Most are an unshielded twisted pair (UTP) type, which is a type of cable that has no shield. In this type of cable, there are two twisted pairs of comer conductors wrapped in polyurethane cladding.
Signals are then sent by the UTP, with aid of electromagnetic propagation properties, by varying voltages and different levels. The other types include fibre optic and shielded cables. These cables will often be more expensive, due to the nature of their build, whereby they are more complex, often with protective casing.
A shielded cable is very useful when they are placed in an environment whereby reliable transmission communication is vital, and could be at risk due to the surroundings. Shielded cables are most often used where electromagnetic transmissions from networking cables can generate problems. Fibre optic cables are extremely good for purposes requiring more bandwidth, but are very fragile and can be quite expensive. Stranded cables are the most basic type, which are cost effective and suitable for indoor day to day use.
