Electric Cable

Type of Power Cord
There are many types of electrical cables, the following are:
a. NYA cable is a type of cable that is often used for home installations and in home installations that are often used is the size of 1.5 mm2 and 2.5 mm2, which is single core, coated PVC insulation material The color code of insulation is red, yellow , blue and black. The insulation layer is only 1 layer so that it is easily deformed, not water resistant (NYA is a type of aerial cable) and easily bitten by a mouse. To be safe if using this type of cable, it is better to install the cable inside a pipe or duct, because besides being unable to be disturbed by rodents and not exposed to water, also if there is insulation that is peeled off (open) can not be touched directly by humans.
b. NYM cable is a type of cable that is only recommended specifically for fixed installations in buildings where the placement is usually outside / inside the wall or inside the pipe (conduit).
c. NYY cable is a type of cable designed for fixed installations in the ground where special protection must be provided (eg duct, PVC pipe or iron pipe). Protodur cable without metal holster. Installation can be placed inside and outside the room, in humid or dry conditions, has a PVC insulation layer (usually black), some are nucleated 2, 3 or 4. And have a layer of insulation that is stronger than NYM cable (the price is more expensive than NYM). NYY cables have insulation made from materials that mice don't like.
d. NYAF cable is a type of cable recommended for installation in a cable distribution box or in the duct. NYAF cable is a type of flexible cable with copper conductor PVC insulated fibers. Used for the installation of panels that require high flexibility.
e. NYFGbY / NYRGbY / NYBY cable is a type of cable specifically designed for fixed installations in directly planted land without the need for additional protection (except having to cross a road). Under normal conditions the underground installation is 0.8 meters.
