Test method for dielectric strength of insulated wire and cable
The insulation strength of wires and cables refers to the ability of the insulation structure and insulation materials to withstand the action of an electric field without breakdown. In order to check the quality of wire and cable products and ensure the safe operation of the products, insulation strength tests are generally required for all insulation types of wires and cables. .

What are the advantages of single-core cables and multi-core cables?
The advantages of single-core cables are small cross-sectional area ratio, not easy to oxidize, short-circuit capacity impact resistance, and long service life. The disadvantage of single-core wires is that the wire is relatively hard, and it is difficult to pull the wire in some places, so it is difficult to straighten after bending, and it is easy to damage the wire after repeated bending. Advantages of multi-core cable Multi-core cable refers to a cable with an upper insulating layer of copper core cable

Do you know what problems are prone to occur in the operation of wires and cables?
As my country's industrial level is getting higher and higher, it can be said that wires and cables are everywhere. In recent years, the construction of cables into the ground has also developed very rapidly. However, with the increasing number of cable lines and the increase in operating life, cable faults Gradually increasing, the faults of the cable body, cable accessories, and cable auxiliary equipment that occurred during the cable operation also increased significantly. The reasons for these faults will now take everyone to take a look.

The ability to prevent and control electric safety accidents should be strengthened in summer
On the basis of maintaining the safe operation and correct operation of power equipment, more attention should be paid to the quality of equipment and materials used as power transmission, especially in summer. The quality of wires and cables should be paid more attention to. Electricity is not like other dangerous things. It is invisible and intangible, but if you are negligent, you will often pay a huge price with your life. You can even call electricity an electric tiger, but in fact electricity itself is more terrifying than a tiger.
