High Temperature Cables: Reduce Unnecessary Replacements and Avoid Downtime

June 27, 2016 — by Richard Dawson

In general, cables are under immense temperature pressure because of the energy and heat that the flow of current through them emits. In order for extreme fire chaos to be avoided, the first thing to be taken into consideration is the choice of heat resistant materials for building those cables. There are various materials that can be used to provide insulation from high temperatures and make the cables useful.

High temperature cables serve to withstand extreme temperature changes that come down to extremely strong cold and hot influences. They’re designed with a special core and a layer of insulation made from a specific type of material depending on the purpose of use of the cable. The main areas where high temperature cables are used include power stations, iron works, foundries and factories for cement, ceramic and glass. They’re also used in aircraft construction and shipbuilding, brickworks and design of kitchen appliances – basically everywhere where constant flow of current is included and the result may be a fire caused by an overheated use of the device.

For these high temperature cables various types of materials are used in order to offer high functionality and safety. Among the most commonly used ones are silicone, rubber and fluorinated polymeric materials. The thing that distinguishes all of them is the specific area of application of each type: besides the aforementioned areas of use, heat resistant cables are also used in lamps and lamp holders in heat and air-conditioning systems and leakage monitoring systems. Each type of cable has its own specifics.

Silicone cables

In applications where the cable insulation is subjected to dangerous and extremely high temperature fluctuations, silicone-rubber insulated cables are used. These cables can withstand temperatures of up to +220 degrees Celsius, but only on short periods. The lower range can go down to -60 degrees Celsius thanks to the weathering resistance these cables have, which is excellent. These are mainly used for applications in iron and steel works since they are also halogen-free.

Fluorinated polymeric cables

Also known as teflon cables, these are generally used in applications such as control cabinets that are subjected to high temperatures, like kitchen fitments, measuring appliances, heaters, brick-works and similar. However, these aren’t as heat resistant as the silicone-rubber insulated ones; their temperature range is from 100 degrees Celsius up to 205 or 230 degrees Celsius in some cases but for very short periods.

Besides these most popular types of cables and most frequently used ones, the market also offers variations of them with even more great features for an even higher degree of protection. With the addition of other materials like nickel, copper and steel, the cables gain even more strength and resistance features.

Outsourcing the IT support component of your business to a third-party company is not only the best way to save on operational costs but also to ensure proper maintenance of your system. There are many IT companies in Australia, however not all are trustworthy. If you do not want to risk your data, choose a reputable and trustworthy company. Here are some tips that can help you find the best one.

Think Global, act Local. Hiring a local IT support company can benefit you business more in terms of productivity and efficiency than hiring a company that is headquartered hundreds of kilometers away from your business site. For example, if you are located in Melbourne, you will get a reliable 24/7 service only if you hire a tech support company that is also located in Melbourne. No matter if you need a quick fix or a solution to a more serious problem, travel time and distance should not delay the response time of your IT consultants.

Check into the content of the Contract/Service Agreement thoroughly. Ask for a written contract where the type of services, for example server management, data recovery services, domains/web hosting or computer repairs, etc., the company provides are clearly listed. Also, in the service agreement the IT consultant company should provide the information associated with the performance of the personnel and the quality of the services. Such details include: approximate time needed for responding in case of normal or emergent IT issues, exact hours of availability during the day, time needed for resolving issues that happen commonly at your work site and so on. Also, the company should clearly list the prices for each type of services.

Choose a company that has high customer rating. Be sure you partner with the IT provider that has the expertise to provide reliable and satisfying solutions to your IT issues. Remember, there is never a good time for your system to fail, therefore find a trustworthy company that offers 24/7 support including remote monitoring. To make a good choice, the most important factors that you need to take into account include:

  • number of years company has been in the industry
  • qualifications, experience and certification of its personnel
  • communication
  • trust and security
  • contingency planning
  • response time.

Arm yourself with information before you hire. Read reviews online and ask for references from acquaintances, business partners and other companies that are in the same or similar industry as yours. A word of a mouth is in most cases, more trustworthy than any other form of advertising.
