fuel level gauge cluster wire color
Although the color of car wire looks very common, it contains many definitions. Now I will talk about the definition of car wire, hoping to help you understand more about car wire harness. Fuel level gauge cluster wire color general is red.
First of all, we introduced that the material of wire insulation layer is generally PVC, XLPE, XLPO, etc. The colors of these materials are transparent, light yellow, white, etc., not the colorful colors we see on the wire. We call the colors of these materials natural colors (natural colors are those that have not been dyed and maintain their own colors). The colors we see are made of these materials dyed by color masterbatch.
The color masterbatch is a plastic color additive made of a high proportion of pigment or additive and thermoplastic resin, which is well dispersed. The selected resin has good wetting and dispersing effect on the color additive, and has good compatibility with the colored material. That is, pigment+carrier+additive=color masterbatch. The following figure shows the common color masterbatch.The color of wire can be single color, double color or three color (less used). The color marking of automobile wires is generally defined as main color, secondary color and color ring. Generally, the main color and secondary color are enough for us to use, and the appearance of color ring is rare. Of course, there is a certain value for the range of secondary colors. If it is too large, it will affect the recognition of primary and secondary colors. If it is too small, it will be difficult to see clearly. Take GM and Ford standards as an example, the secondary color should account for 7% - 15% of the insulation layer.With the increase of automobile electrical equipment, the number of wires is also increasing. In order to facilitate maintenance, low-voltage wires are often distinguished by different colors. Monochrome is often used for those with a sectional area of more than 4mm2, and two-color is used for those with a sectional area of less than 4mm2. The colors of automobile wires generally include: black, brown, red, orange, yellow, green, blue, purple, gray, white, light green, sky blue, and pink
