Flame-Retardant XLPE Power Wire Equals Fire-Resistant Wire?
First of all, let's understand what is a flame retardant wire? The flame retardant wire can prevent the spread of the fire in the event of a fire, and it can be automatically extinguished when there is no fire source. In layman's terms, in the event of a fire on the wire, the burning can be limited to a local area without spreading, and other various equipment can be protected to avoid greater losses.
Let's learn more about what is fire-resistant wire. Fire-resistant wires refer to wires that can maintain safe operation for a certain period of time under the condition of flame combustion. Fire resistant wire is actually another type of fire resistant wire. It is made of copper as the conductive core, seamless copper tube as the sheath, and inorganic mineral magnesium oxide as the insulating material.
Since the whole is composed of inorganic materials, the entire fireproof wire neither burns nor delays burning, and can withstand fire.
This is the difference between the two wires!
The principle of fire-resistant cable is different from that of flame-retardant cable. The flame retardant principle of halogen-containing wires and cables is based on the flame retardant effect of halogen, and the flame retardant principle of halogen-free cables is to extinguish the fire by reducing the temperature of the precipitation water. Fire-resistant wire and cable rely on the fire-resistant and heat-resistant properties of mica material in the refractory layer to ensure that the cable works normally in the event of a fire.
For household wires, whether it is a fire-resistant wire or a flame-retardant wire, it can basically meet the needs of most household wires, as long as you don't buy inferior wires. So
Look at the appearance of the wires. Including the packaging of the wire, and the appearance of the wire insulation. The first point to look at the appearance is to look at the wire packaging. The packaging of the wire should have all the parameters of the wire, the certificate of conformity and the implementation standards.
Then open the XLPE wire package and look at the insulation mark of the wire. There should be a clear mark on the outside of the insulation layer, including the manufacturer's mark, the type of wire diameter, etc., look at its model and size, and once it is found that there is no specification or is unclear, At this time, you should pay attention, you may encounter inferior products.
