Tray Cable PLTC PVC/PVC Shielded Pairs Overall Shield (SPOS) 300V
This is a tray cable whose design is a combination of quality, class and power. It is a top notch design, endowed with varied excellent features. Tray Cable PLTC/ SPOS is not an ordinary cable, it has earned numerous excellent reviews and enjoys industrial approves from UL and NEC among many other approvals.
The cable is constructed using copper material. Copper is an excellent and readily available conductor, this makes construction of quality and affordable cables. Copper used here is class B stranded to improve its efficiency. The conductors are of various sizes from 18AWG to 16 AWG designed according to ASTM B-3 and B-8.
Its insulation is constructed using premium grade and strong Polyvinyl Chloride material. The PVC has high flame and sunlight retardant. It is a mechanical protector, thus guarantees longevity to the conductors.
Each individual conductor is shielded all around using aluminum/polyester foil shield. The shield is necessary in preserving the signal integrity, reducing current loss or errors in measurement. It also reinforces the cable conductors.
An overall protection is provided by the sunlight and moisture resistant PVC jacket. It is black in color and extra strong, protecting the cable from any damages.
• The Tray Cable is always black or while, with alpha-numeric print. This is power cable used in various utilities both commercially and industrially. It is suitable for use in complex control unit circuits for substations. Being rated at 300V rms maximum, it useful for smaller power utilities.
• The cable has temperature range of -30 to 900C, therefore suitable to be used in various applications in extreme weathers. It can be used in cable trays, above ground and direct burial applications.

FAQ Shielded tray cable POS paired overall shield and SPOS shielded
How to identify shielded tray cable POS (paired overall shield) and SPOS (shielded pairs overall shield)?
It is necessary that you are able to identify your cables so that you can make informed choices, especially when you want to place an order. First of all you must know about the wire size, which will tell you how big the conductor is and it is measured in AWG (American Wire Gauge). The insulation for the conductors will usually come in EPR or PVC. POS cables will have an overall shield while SPOS will have shielded pairs with an overall shield.
Are POS/SPOS shielded tray cables the right choice for a conduit system?
Yes, they are but there are also many other cables available in the market that are suitable for a conduit system. However, these cables are economical and they come with a sheath that is virtually impermeable. Most of these cables come with PVC or EPR with TC-ER, individual shielding that comes with 100% coverage.
What are the different types of shields of POS and SPOS cables?
There are different types of shields available for both the POS and SPOS cables. The most common types of shields available in the market are the PVC flame retardant ones. You might also see ones with “ER” (Extended Run) which will have the same crush and impact specifications as that of an UL Type MC cable. You can also find TPE, EPR, CPE and Haloarrest jackets for shielded tray cables.
Why is an overall shield important?
An overall shield will be considered important only when the shielded tray cables are used under the following conditions –
- Extreme environmental conditions –humidity level, temperature of work area
- Installation method - especially if it has to be buried or has to be outdoors
- Exposure to certain elements like oil or grease
- High risk of fire
What is the difference between a POS and SPOS?
POS simply means that the cable has a single pair with an overall shield or jacket. While SPOS is a cable that has shielded pairs that in turn are covered with an overall shield or jacket. Both types are used for wet and dry locations and also for any type of indoor and outdoor applications.
Is the insulation thickness a vital deciding factor for choosing a shielded cable?
The insulation thickness is a deciding factor for any type of cables, regardless of whether they are shielded or unshielded. It pertains to the conductor specifications, the voltage that it will be required to work under and the strength of the cable. Also, when the insulation is thick, it will affect the flexibility of the cable.
