Different Types of Electrical Wiring Systems?

The types of internal wiring usually used are

  1. Cleat wiring
  2. Casing and capping wiring
  3. Batten wiring
  4. Conduit wiring

1. Cleat Wiring

This system of wiring comprise of ordinary PVC insulated wires (occasionally, sheathed and weather proof cable) braided and compounded held on walls or ceilings by means of porcelain cleats, Plastic or wood.

Cleat wiring system is a temporary wiring system therefore it is not suitable for domestic premises. The use of cleat wiring system is over nowadays.

Advantages of Cleat Wiring:

  1. It is simple and cheap wiring system
  2. Most suitable for temporary use i.e. under construction building or army camping
  3. As the cables and wires of cleat wiring system is in open air, Therefore fault in cable can be seen and repair easily.
  4. Cleat wiring system installation is easy and simple.
  5. Inspection is easy and simple.

Disadvantages of Cleat Wiring:

  1. Appearance is not so good.
  2. Cleat wiring can’t be use for permanent use because, Sag may be occur after sometime of the usage.
  3. In this wiring system, the cables and wiring is in open air, therefore, oil, Steam, humidity, smoke, rain, chemical and acidic effect may damage the cables and wires.
  4. it is not lasting wire system because of the weather effect , risk of fire and wear & tear.
  5. There is always a risk of fire and electric shock.
  6. it can not be use in important and sensitive location and places.
  7. It is not lasting, reliable and sustainable wiring system

2. Casing and Capping wiring

Casing and Capping wiring system was famous wiring system in the past. The cables used in this kind of wiring were either VIR or PVC or any other approved insulated cables.

The cables were carry through the wooden casing enclosures. The casing is made up of a strip of wood with parallel grooves cut length wise so as to accommodate VIR cables.

The grooves were made to separate opposite polarity. the capping (also made of wood) use to cover the wires and cables install and fitted in the casing.

Advantages of Casing Capping Wiring:

  1. It is cheap wiring system as compared to sheathed and conduit wiring systems.
  2. It is strong and long-lasting wiring system.
  3. Customization can be easily done in this wiring system.
  4. If Phase and Neutral wire is install in separate slots, then repairing is easy.
  5. Stay for long time in the field due to strong insulation of capping and casing..
  6. It stays safe from oil, Steam, smoke and rain.
  7. No risk of electric shock due to covered wires and cables in casing & capping.

Disadvantages Casing Capping Wiring:

  1. There is a high risk of fire in casing & capping wiring system.
  2. Not suitable in the acidic, alkalies and humidity conditions
  3. Costly repairing and need more material.
  4. Material can’t be find easily in the contemporary
  5. White ants may damage the casing & capping of wood.

3. Batten Wiring :

Single core or double core or three core cables with a circular oval shape cables are used in this kind of wiring. Mostly, single core cables are preferred. cables are chemical proof, water proof, steam proof, but are slightly affected by lubricating oil. The cables are run on well seasoned and straight teak wood batten with at least a thickness of 10mm

AV TECHNICAL SERVICES: What is Batten Wiring ?

therefore, The cables are held on the wooden batten by means of tinned brass link clips (buckle clip) already fixed on the batten with brass pins and spaced at an interval of 10cm for horizontal runs and 15cm for vertical runs.

Advantages of Batten Wiring

  1. Wiring installation is simple and easy
  2. cheap as compared to other electrical wiring systems
  3. Paraphrase is good and beautiful
  4. Repairing is easy
  5. strong and long-lasting
  6. Customization can be easily done in this wiring system.
  7. less chance of leakage current in batten wiring system.

Disadvantages of Batten Wiring

  1. Can’t be install in the humidity, Chemical effects, open and outdoor areas.
  2. High risk of firs
  3. Not safe from external wear & tear and weather effects (because, the wires are openly visible to heat, dust, steam and smoke.
  4. Heavy wires can’t be used in batten wiring system.
  5. Only suitable below then 250V.
  6. Need more cables and wires.

4. Conduit Wiring

There are two additional types of conduit wiring according to pipe installation

  1. Surface Conduit Wiring
  2. Concealed Conduit Wiring

1.Surface Conduit Wiring

If conduits installed on roof or wall, It is known as surface conduit wiring. in this wiring method, they make holes on the surface of wall on equal distances and conduit is installed then with the help of rawal plugs.

2.Concealed Conduit wiring

If the conduits is hidden inside the wall slots with the help of plastering, it is called concealed conduit wiring.

In other words, the electrical wiring system inside wall, roof or floor with the help of plastic or metallic piping is called concealed conduit wiring. obliviously, It is the most popular, beautiful, stronger and common electrical wiring system nowadays.

Concealed wiring

Advantage of Conduit Wiring Systems

  1. It is the safest wiring system (Concealed conduit wring)
  2. Appearance is very beautiful (in case of concealed conduit wiring)
  3. No risk of mechanical wear & tear and fire in case of metallic pipes.
  4. Customization can be easily done according to the future needs.
  5. Repairing and maintenance is easy.
  6. There is no risk of damage the cables insulation.
  7. it is safe from corrosion (in case of PVC conduit) and risk of fire.
  8. It can be used even in humidity , chemical effect and smoky areas.
  9. No risk of electric shock (In case of proper earthing and grounding of metallic pipes).
  10. It is reliable and popular wiring system.
  11. sustainable and long-lasting wiring system.

Disadvantages of Conduit Wiring Systems

  1. It is expensive wiring system (Due to PVC and Metallic pipes, Additional earthing for metallic pipes Tee(s) and elbows etc.
  2. Very hard to find the defects in the wiring.
  3. installation is not easy and simple.
  4. Risk of Electric shock (In case of metallic pipes without proper earthing system)
  5. Very complicated to manage additional connection in the future.
