Cleat Wiring: Ordinary VIR or PVC insulated wires (sometimes encased and weatherproof cable) braided and compounded are secured on walls or ceilings by porcelain cleats, plastic, or wood. Because cleat wire is a temporary wiring system, it is not ideal for home use. The cleat wiring method is no longer in use.
Casing and Capping Wiring: Casing and capping wiring systems were popular in the past, but Conduit and encased wiring systems have rendered them obsolete. VIR or PVC cables and any other permitted insulated cable were utilized in this type of wiring.
Batten Wiring: This type of wiring uses TRS cables that are single-core, double core, or three core with a circular, oval shape. Single-core cables are the most common choice. TRS cables are chemical, water, and steam resistant; however lubricating oil has a minor impact on their performance. TRS wires run on a 10mm thick, well-seasoned and straight teak wood batten.
Lead Sheathed Wiring: Conductors are insulated with VIR and covered with an outer sheath of a lead aluminum alloy containing roughly 95% lead in this form of wire. Cables were protected from mechanical damage, moisture, and air corrosion by the metal wrapping.
Conduit Wiring: Surface conduit wiring occurs when conduits are put on the roof or wall. In this wiring approach, holes are drilled through the wall at equal intervals, and the tube is fitted using rawl plugs. Concealed conduit wiring is when the conduits are hidden inside the wall slots with the help of plastering.
