CTS or TRS wiring (Batten Wiring System)

CTS or TRS wiring (Batten Wiring System)

In this type of wiring the cables used may single core, twin core or three cores T.R.S cables with a circular over shape.
Usually single core cables are preferred. T.R.S cables are sufficiently chemical proof water proof, steam proof but are silghtly effected by lubricating oils.

T.R.S cables are run on well seasoned, perfectly straight and well varnished (on all four sizes) teak wood batten of thickness 10mm at least.
The Width of the batten depends upon the number and size of cable to carried by it.

The battens are available in width of 13, 19, 25, 31, 38, 44, 50, 63, 69, and 75 mm.
The wood battens are secured to the walls or ceiling by flat head wood screws to wood or other approved plugs at an interval not exeeding 75 cm.
The cables are held on the wood by means of horizontal runs and 15 cm in case of vertical runs.
The wiring after erection os neatly painted with two coasts of oil non crackig paint, as specified in IS 732 and so on.

ADVANTAGES:

 1.  Its installation is easy and quick and saving in labour largely compensate for the extra cost of the cable.
 2. Its life is long.
 3. Within certain limits it is fire proof.
 4. It can withstand the action of most chemicals such as acids and alkalies.
 5. It is cheaper than other types of wiring except claest wiring.
 6. If the job is carried out with proper attention, it gives a nice appearance.

DISADVANTAGES:

 1. Good workmanship is required to make a sound job in TRS wiring.
 2. This type of wiring can not be recommended for use in situations open to sun or rain unless preventive steps are taken to preserve the insulation of cables.

FIELDS OF APPLICATION:

The TRS wiring is suitable for low voltage installations and is extensively used for lighting purpose every where i.e. in domestic, domestic, commercial or industrical buildings except workshop where it is liable to mechanial injury.
This type of wiring is suitable in situations where acids and alkailes are likely to be present.

PRECAUTIONS:

 1.  The battem used must be of well seasoned and perfectly straight teak wood and of thickness 10 mm at leat.
 2. The batten should be well varnish (on all four side).
 3. The wooden gutties or plugs to which batten is to be fixed should be spaced at an interval not exceeding 75 cm.
 4. While passing through structural steel works the wooden bushes should be provided in holes, and also at the ends of conduit or pioe used while wiring is being passed through walls or ceilings.
 5. Fibre clips should not be used in damp situations as these are hydrosocopic.
 6. The ends of the cables must be sealed with compounds in damp situations.
 7. When the cables are to pass through floors, walls, partitions or other concealed locations, they must be carried through conduits.
 8. The wiring after erection must be neatly painted with, two coats of oilless non-cracking paint, as specified in IS 732.
 9. If the fittings are accessories are to be erected in damp situations, patterns with suitable glands and of thoroughly good water tight construction must be chosen.
