Question

What is C T S or T R S wiring?

Answer 1

C T S (cable tyre sheathed) or T R S (Tough rubber sheathed) wiring:

1. Tough rubber sheathed (T.R.S) is a type of internal wiring that was invented by the St. Helens Cable Co., and is typically overtaken onto an already insulated conductor named C.T.S. (cable tire sheath).
2. In the tough rubber sheathed cable, the conductor is insulated with vulcanized rubber insulation.
3. In this wiring system, wires sheathed in tough rubber are used which are quite flexible. They are clipped on wooden battens with brass clips (link or joint) and fixed onto the walls or ceilings by flat head screws. These cables are moisture and chemical-proof.
4. They are suitable for damp climates but not suitable for outdoor use in sunlight. TRS wiring is suitable for lighting in low voltage installations
5. T.R.S or CTS cables are constructed in such a way that mechanical damage is tolerated.
6. To protect the cable from external damage, a hard rubber cover is used.
7. A hard rubber shield is being used to protect the cable from external damage.
8. In open wiring systems, such a type of cable is widely used. The outer sheath cover provides mechanical protection that the cable does not have for electrical insulation.
9. The sheath cover has an overall diameter of $0.5\mathrm{cm}$. It is used for residential and commercial purposes.
10. In this type of cable, a strong rubber or thermoplastic cover has been used on single-core, two-core, or three-core V.R.I (vulcanized rubber insulated) cable.
