The first types of power cables are the NYA type. This type of electrical wiring is used in home installations and power systems. In ordinary home installations, NYA cables are used with sizes of 1.5 mm2 and 2.5 mm2.
This type of cable is coated with PVC insulating material with the red, yellow, blue, and black color codes for the insulation. This type of power cable is commonly used in housing because the price is relatively cheap.
This cable should be installed in a PVC pipe/conduit or closed conduit so that it does not become a target for rat bites. In addition, if the insulation on the cable is peeled off, it will not be directly touched by people.
