Choosing the right cables depending on purpose is very important. There are many wires and cables that are available nowadays. You should consider the purpose of a wire or cable. Your primary concern is to avoid short circuits that may lead to worse incidents. You should know the conductors, insulation and protective jacket used in a cable. One of the most commonly used in the electrical industry today is the large single insulated conductors called electric insulated power cables.
The types of power cables vary in size, materials used and other aspects. Good cables have high quality conductors and good insulation. Some may have shields or armours for added safety. One of the most common in the industry is the insulated armoured XLPE power cables. An instrumentation cable engineer specifies conductors like copper or silver. He also considers the insulation such as PVC, XLPE and rubber. Different insulations each have specific properties in terms of physical, electrical, chemical and thermal aspect. An XLPE insulated power cable is very low cost and offers excellent electrical properties.
The PVC shielded control cables are not that costly but is very heat resistant. These PVC cables have good electrical and physical properties as well as excellent abrasion. In addition, PVC shielded control cables are great for the additional safety measure they bring. Shields are somewhat necessary especially when there is high frequency interference. The armour, on the other hand, provides mechanical protection to cables. Make sure that you buy high quality insulated armoured XLPE power cables or PVC shielded control cables from reputable instrumentation cable manufacturer to avoid unwanted and dangerous incidents that wrong cables may bring.
