AIM : TO STUDY CONSTRUCTION OF CABLES AND CONCEPTS OF WIRING SCHEMES.

Conclusion : it is important to first have a basic understanding of electricity and electrical circuits. It is also helpful to study electrical codes and standards to ensure that your wiring is safe and meets regulatory requirements.

Question :

Q1 ] Draw the cross-section of cable with notations.
Ans :

Q2 ] Why casing capping wiring scheme is preferable in domestic wiring? Explain in detail.
Ans : It is cheap wiring system as compared to sheathed and conduit wiring systems. It is strong and long-lasting wiring system. Customization can be easily done in this wiring system. If Phase and Neutral wire is installed in separate slots, then repairing is easy

Q3 ] Explain the function of armouring in detail.
Ans : Steel Wire Armour (SWA) used for mechanical protection. That way the cable can withstand higher stresses, be buried directly and used in external or underground projects.

1. Mechanical protection against crushing, bending, twisting, or abrasion.
2. Environmental protection against moisture, chemicals, UV radiation, and other corrosive substances.
3. Resistance to rodent and pest damage.
4. Electromagnetic interference (EMI) shielding to minimize EMI or RFI.
5. Durability and longevity, extending the lifespan of the cable.
