Do you know what inspections should be done after the cable arrives?

1. Prepare the cable acceptance tools: steel tape measure and vernier caliper. 2. Cables need to be inspected randomly. After all, many people buy a lot of cable products at a time. The quality and performance of the same batch of cable products are similar. If they are to be checked and accepted one by one, a lot of time will be wasted. It is better to check and accept. The cable sampling ratio is based on the incoming batch, and the same specification model is not less than 3 coils for cable acceptance.

What are the differences between photovoltaic cables and ordinary cables?

Radiation cross-linked data has high mechanical strength. The cross-linking process changes the chemical structure of the polymer and transforms fusible thermoplastic data into non-fusible elastomeric data. Cross-linking radiation significantly improves the thermal, mechanical and chemical properties of the cable insulation data.

Do you know the causes and solutions of common wire and cable neutral wires

The live wire, neutral wire, and ground wire are all wires connected to the three-hole socket, and a sinusoidal oscillation pressure difference is maintained between the live wire and the neutral wire. Since the earth and the neutral wire have the same potential, the live wire and the ground wire also maintain a sinusoidal oscillation pressure difference. 　　 When the human body touches the live line, the person is standing on the ground. The current of the live line flows into the earth or the neutral line through the human body, and an electric shock will occur, while the neutral line will not be shocked. Connect the shell of the electrical appliance whose shell can conduct electricity to the ground wire. In the case of electric leakage, the current will directly flow into the ground through the ground wire without passing through the body, thereby avoiding electric shock accidents. 　　The zero line is charged with a lack of good grounding. If it is well grounded, the current will flow into the ground and it will not be detected with a test pencil. If the test pencil detects that the neutral line is live, either the neutral line is broken or the contact is not good. Therefore, this is not the cause of the neutral line being charged. Cause Analysis 　　 Under normal circumstances, there should be no electricity on the neutral line. Therefore, once there is electricity, it must be a fault; the simplest is electromagnetic induction, and at this time, the neutral line is not well grounded and a loop cannot be formed;

Do you know what obstacles need to be resolved to develop wires and cables?

1. The quality of wire and cable products is low, and the wire and cable industry has many problems such as "winning the bid at the lowest price" and "low-price competition". These problems have made it difficult for my country's wire and cable products to be competitive in the international market, and malicious competition in the country has caused internal friction. 2. In the wire and cable market, there is a market structure in which buyers are monopolized or highly concentrated in subdivisions, and sellers are scattered, which leads to chaotic market order, loss of market regulation mechanisms, and difficulty in solving the problem of optimal allocation of resources. 3. The concentration of superior cable companies in my country is low, and the industry's instability is high. At present, there are nearly 10,000 manufacturers in the cable industry in China, and there are thousands of supporting industries such as equipment deployment, raw materials, and semi-finished products, but the concentration is extremely low. According to Global Plastics, the top ten cable companies in China only account for 7%-10% of the domestic market. The developed countries, including the United States, Japan, and developing countries, account for more than 60% of the country's market share.
