The impact of inkjet printers on the cable industry

Soon it will be the Chinese traditional festival-the Spring Festival. At the end of the year, all enterprises have paid more attention to the string of safety. After all, everyone hopes to be peaceful.< /p>

Spend the new year peacefully and welcome the new year with a brand new look.

Cable is the most basic component for each enterprise and the foundation of national construction. The quality of the cable will determine the basis of safety. Wires and cables are a large class of electrical products used to transmit power, transmit information and realize electromagnetic energy conversion. Wires and cables play an important role in all economic activities and social life. Therefore, the safety of the cable is worthy of everyone's attention.

According to information from the fire department, in recent years, about half of the fires in my country are caused by Electrical fires, among them, the fires ignited by wire and cable faults account for about 40% of the electrical fires

With the increasing complexity of the power distribution system of civil construction projects, the amount of wires and cables has increased, the varieties and specifications are complicated, and the laying methods are diverse. Probability of failure. Therefore, in order to reduce the occurrence of electrical fires in civil construction projects and reduce the personal injuries and property losses caused by fires caused by the burning of wires and wires

The reliable operation of wires and cables must be improved sex. There are several situations that cause wire and cable fire in daily life:

1. After a single-phase grounding (short circuit) accident occurs in the wire and cable, the relay protection device is cut off due to inaction Overheating of wires and cables caused by faults leads to spontaneous combustion of the insulation.

2. The root cause of fires caused by wires and cables is that the materials of the cable insulation and sheath (such as plastic, rubber, oil-impregnated paper, etc.) are flammable. Copper of wire and cable

The melting point of the core is 1083℃, the melting point of the aluminum core is 658℃, and the melting point of the cable insulation layer is much lower than this, for example, the melting point of polyethylene is only 200. ℃.

3. When the wire and cable intermediate joints and branch T-junctions are processed, the contact resistance increases due to the weak wire connection, which causes local overheating, which will cause the insulation layer to age and spontaneously ignite.

It is an aluminum core wire and cable. The aluminum core wire will oxidize in the air and increase the resistance of the oxide layer, and the heat generation after power is also increased.

4. The insulation layer of wires and cables will gradually age during normal operation, and their service life is generally 15-20 years. If they are used for too long, often overloaded or Overvoltage,

In addition, the thickness of the insulation layer is not up to the standard, improper installation, etc., may cause disasters.

Choosing a cable with a regular manufacturer is of great significance to the safety of production and life, and the product of a regular manufacturer will be printed with a clear spray Code, the production batch number and other information in the code will be checked on the Internet for the safety of the cable, so the code will protect our electricity safety.
