High Voltage Cables Going Flexible

Transmission of high-voltage power requires an HV or high voltage cable, which come in different varieties and lengths. Shorter cables are used for devices and equipment. Large plants, ships, and establishments have very long and extensive network of cables. High-voltage cables are ubiquitous. Manufacturers have developed these wires so that they become less bulky and more flexible. There is a growing need for the high-voltage flexible cable, which is easier to work with.

High-voltage wires now don’t have to come too stiff. For instance, silicone cables now come with high flexibility and excellent insulation, yet still capable of transmitting high-voltage power.

High-voltage wires are generally thick. Thick wires have low resistance and thus are able to pass electric current without accumulating significant heat. The insulation must be made of tough material to avoid fatal electrocution upon contact. Although these cables are imbedded inside insulation walls, there will be times when people will come in contact with them. Electrical technicians doing cable installations, inspections, and repairs will intentionally come in contact with these cables.

High-voltage wires are susceptible to the damaging effects of corona discharge. Thus, their insulation should be so designed as to be more resistant to corona discharge. Reducing such damage is possible through designing the cables appropriately. A known method involves covering the conductor in semi-conductive casing, a procedure that increases the conductor’s thickness and eliminates the gap between the insulation casing and the conductor.

High-voltage wires come in different designs to meet different applications. Many companies make customized cables that fit the unique needs of the client. Manufacturers usually provide high-voltage wires for other companies, such building companies, laboratories, and hospitals.

Customers need to discuss their specific with the manufacturer so that they get the right cable, because cables used for laboratories have different specifications from those used for movie sets and concerts. In latter cases, cables that are used need to be really flexible so they can be easily removed from a location and reinstalled in the next location. Hence, a super flex wire is the likely option.

Apart from being flexible, cables must be friction-resistant. The insulating casing will always come in contact with smooth or rough surfaces, which will gradually cause wear. People always drag, move, and step on wires. Wires with poor casing can easily get torn. Worn wires are a hazard. Makers of high voltage cable wires encase conductors in polyurethane material, which doesn’t easily get worn, thus giving the wires a higher degree of safety and longevity. Tough encasing is also necessary to resist high-voltage stress, which also cause gradual wear of the insulation.visit http://www.calmont.com/types-of-conductors.php for more details
