The conductors of Guangxi wire cable for electrical equipment must be shiny, the DC resistance conductor structure size must meet the national standard. Wire cable products that meet the national standard, whether it is aluminum conductor copper conductor, are relatively bright oil-free. The conductor DC resistance fully conforms to the national standard, with good electrical conductivity high safety.

1. the packaging point of view, the national standard line is well-made, neat, has a texture in the hand. Guangxi cable

2. Open the package to see the wires inside. The national standard line 1.5-6 square line requires a skin thickness (insulation thickness) of 0.7mm, it is standard if it is too thick. Therefore, his mind must be enough. Silk skin can be pulled hard. Generally, it is easy to break the national standard.

3. Bake with fire. When it disappears within 5s after leaving, the national standard line has a certain flame retardant function.

4. Look at the inner core, the higher the brightness of the inner core material (copper), the better the copper quality, the brightness is uniform, the gloss is, there is no delamination. The national standard requires that the inner core must use oxygen-free copper. Non-targets are like black pressed copper can be at risk of accidents.

5. Countries have certain requirements on the thickness of the iron core, but they are strict. However, there are many errors. It's just a little, usually an invisible bug.

6. Length. In my country, rice milling is mandatory, but many manufacturers are also milling rice. Rice is necessarily the national standard, but ordinary national standard is ordinary rice. Off-target meters are just a means.Guangxi wire cable

7. my country stipulates that wires must have certain signs. If more than 500mm, the same mark will be added as below. It has the product's trademark, manufacturer's name, implementation standards, etc.

Scope of application of wire cable for electrical equipment:

Power system: The wire cable products used in the power system mainly include overhead bare wires, busbars (busbars), power cables), plastic cables, oil-paper power cables, overhead insulated cables), magnet wires, electrical equipment power equipment. Wire cable)

Information transmission system: The wires cables used in the information transmission system mainly include local telephone cables, TV cables, electronic cables, radio frequency cables, optical cables, data cables, electromagnetic cables, power communication other composite cables.

Mechanical instrumentation system: This part applies to most products other than overhead bare wires, mainly power cables, magnetic cables, data cables, instrumentation cables, etc.Guangxi cable manufacturer

Electrical equipment wire cable code specification:

The size of the wire is important. General household power cords use BVV22.5 BVV21.5 type wires. BVV is the national standard code, copper-clad double-wire BVV22.5 BVV21.5, respectively representing 2 cores 2.5 square millimeters 2 cores 1.5 square millimeters. Generally speaking, BVV22.5 is the main line main line, BVV21.5 is the single power branch line switch line. The one-way air conditioner dedicated line uses BVV24, a dedicated grounding wire is also available.
