Spring Festival, purchase, dinner is our traditional program. When we go to the supermarket with the family shopping, see Ling Lang everywhere all kinds of New Year, can think of such a happy and peaceful environment needs how security.

General provisions, three-phase color is yellow, green, red, A, B, C three-phase respectively, and the blue is zero line, yellow, green and white for the grounding wire, wire connection with yellow, green, red, blue to zero, yellow and green line of receiving PE confirmed on A convenient or in recei

The basic structure of the industrial bus cable generally has conductor, insulation layer and outer sheath, the conductor is used to conduct current, mainly divided into solid and twisted two, conductor made of aluminum, copper and so on.

In the wire and cable DC resistance of the detection, the main is to detect the actual conductive wire and cable situation. Therefore, the DC resistance of the data can directly reflect the wire and cable materials in the good and bad and the main wire and cable conductivity level.

From a macro point of view, the entire Chinese wire and cable industry, is in the rapid growth period of development. Although the price of major raw materials such as copper, aluminum, plastic and so on has soared, many cable companies are struggling to survive. However, China's "Eleventh Five-Year

Cable in the cable and cable accessories installed after the completion of the DC voltage test should be [preventive test]. And the experimental data were compared and analyzed. Which can be compared with the experimental data of the same cable, and can be compared with the historical data of this c

The power cable core is prone to sharp burrs during the pressing process. As the operating voltage increases, the electric field on the conductor surface increases, and the electric field of the burr tip is seriously distorted, causing the main insulation dendritic discharge.

In the heat has a good performance. Why do these products appear in the market? The main reason is because consumers actually use the product demand. We all know that the cable in the course of the use of heat, when the cable temperature is too high not only affect the performance of the product, bu

Flame-retardant wire and cable can usually be divided into general c, low smoke low halogen flame retardant wire and low smoke halogen-free flame retardant wire and cable.

Household electricity, are generally three-phase electricity, but also three colors of the line, each color has a common name of the connection, although sometimes can also be used to reverse, but the latter part of the problem affecting the maintenance.
