What Features Describe Instrumentation Cable 300-600/1000 Volts
Instrumentation cables designed for marine and drilling operations are conductors that are used in signal transmission or instrumentation systems. The conductors are made to withstand the harsh marine environment where corrosion and high temperatures take their toll on the equipment and systems. Electrical wiring in these demanding environments should be engineered to meet such challenges. An instrumentation cable such as HW279 SHIELDED PAIRS INSTRUMENTATION CABLE 0.6/1kV Unarmored 110°C Gexol® Insulation Individually Shielded Pairs is designed for such applications. It is rated 110 degrees Celsius and upto 1KV of voltage. There are certain elements that describe instrumentation cable 600/1000 volts and they include:
Extra flexible stranding
These cables are designed using flexible strands. The high strand count is what makes them to be flexible. Flexibility in electrical wiring is needed because it makes it easy for technicians or electricians to work on the cable. It also makes it easy for the cable to bend through when being used in tight areas. Flexibility of the strands ensure that the cable is not damaged or distorted by vibration.
The oil and gas drilling as well as the general marine environments tend to have high temperature. In drilling areas, there is likely to be flame and the electrical wiring used to wire the systems such as CO2 systems, gas protectors, fire protectors, communication equipment, and others should be able to withstand the flame. An instrumentation cable for marine environments may be insulated or jacketed with a material to protect it against flame. The common insulation material you may find with the multi-conductors is cross-linked polyolefin. A jacket made of arctic grade PVC material is also common among these wires. These two materials are resistant to fire and flame and therefore provide protection to the instrumentation conductor.
Armored and sheathed
The cables also tend to be armored and sheathed in design for enhanced strength, performance, durability, and protection. The cables may be armored using braided bronze wire or tinned copper braid. They may be sheathed using the sun resistant arctic PVC, which is also flame retardant.
If you are in the market to purchase instrumentation cable for marine application, you need to know its features and rating. Look at the temperatures and voltage and the engineering of the cable to withstand such environment. Soft annealed tinned copper strands may be preferred because they have excellent thermal performance and resistance to corrosion. There are different kinds of these cables. The slight differences in their features and quality could make the difference on where they are to be used. If you choose the wrong cable, you could incur a lot of cost through persist downtimes, repairs, and replacements. Look for instrumentation cables based on their voltage, temperature rating, materials used to make them, the insulation, jacketing, and any other extra protection on the conductor. The cable may also need to be moisture resistant, oil resistant, and abrasions resistance because these elements are frequently found in the drilling and marine environments. Also, get your cables from trusted brands to ensure quality and longevity.
