Continuously welded armor - instrumentation cable PLTC Shielded
Continuously welded armor cable is often used in scenarios where maximum conductor and electrostatic interference protection is needed. It can operate in temperatures of up to 1050C in both wet and dry conditions. However in case emergency overload or short circuits it can operate in temperatures up to 1300C and 2500C respectively. It is has a voltage rating of 300 volts hence suitable for light weight power applications.
Continuously welded armor - instrumentation cable conductors are made from soft bare annealed copper in accordance to ASTM B-3 and ASTM B-8. Copper is used for this application because of its amazing electrical properties and flexibility.
It is made of an individual PVC shield with aluminum polymer tape and a stranded tinned copper drain wire. The insulation is robust and highly flexible which makes it very easy to work with.
The overall shield is made of aluminum polymer tape and a stranded tinned copper drain wire. It relatively protects the conductor from electromagnetic interference and other external forces.
In addition to the overall shield is the cable armor which is made using impervious continuously welded and corrugated aluminum. It offers additional protection to the cable.
The cord has an inner and outer cable jacket. They are both made of PVC material. This material is resistant to flames, sunlight, chemicals, abrasion, corrosion, moisture, industrial solvents, oils, acids, alkalis and radiation.

FAQ - Continuously Welded Armor Instrumentation Cable PLTC Shielded
Where do you use continuously welded armor cables?
These are heavy-duty cables which are preferred for harsh and hazardous environments where the cable has to be constantly exposed to gases, liquids and vapors. This type of cable is preferred for use in places where electrostatic and conductor protection is required. It is most commonly used in mining, pulp and paper industries, petroleum and other commercial and industrial applications.
What is the continuous maximum working temperature of the cable?
As it is designed to be used in harsh environments, the cable can operate at even 250°C when there is a short circuit condition. However, the normal continuous maximum working temperature of the cable is 105°C for both wet and dry locations. The cable can also withstand 130°C when there is an emergency overload condition.
Is the continuously Welded Armor flame retardant?
Yes, it is and that means the cable will not propagate the fire, although it may not continue to work. The cable has a flame retardant insulation made of PVC and also a flame retardant PVC jacket. It has also undergone the following flame tests –
What are the other standards that the Continuously Welded Armor cable meets?
Apart from the already mentioned flame tests, the cable also meets the following standards –
What are the features of the armor of a Continuously Welded Armor cable?
The armored cable is chosen for certain unique properties provided by the armor. The armor will prevent water, oil or gas from entering the cable. It will also prevent corrosion of the cable even when continually exposed to corrosive elements. The armor can be continuously welded and corrugated aluminum.
How is the Continuously Welded Armor cable constructed?
The cable has soft bare annealed copper conductors in triads or shielded pairs. The copper is as per ASTM B-3 or ASTM B-8. You can also see an insulation and an aluminum polymer tape working as an individual shield for 100% coverage. It also has a tinned copper drain wire
What does PLTC stand for and what is it used for?
PLTC simply means Power Limited Tray Cable and is typically used for cables that need protection is hazardous locations. The PLTC is NEC and UL approved for use in various applications.
