The woven net cover is divided into two types: red copper woven net cover and tinned copper woven net cover. The red copper woven net cover is made of pure T2 copper wire as the raw material, and is twill woven. The color is orange. The tinned copper woven net cover is tinned on the surface of bare copper, which has high quality characteristics of oxidation resistance. Both have the same shielding effect. Copper woven mesh performance: high conductivity, large current carrying capacity, small resistance Copper woven mesh advantages: bending resistance, slow reaction, ease fatigue, easy heat dissipation Copper woven mesh use: commonly used in electrical devices, switching appliances, electric furnaces, batteries, equipment, machinery, automobile, grounding and other industries, mainly used in conductive, power transmission, non horizontal direction

Many friends who order copper stranded wire have difficulty in distinguishing the quality of products, so they often buy something that is not so satisfactory. So, in the eyes of people who often contact with copper stranded wire, how can we tell the quality of copper stranded wire at a glance? Next, let's use four eyes to popularize this method! The first thing is to look at the appearance of copper stranded wire. The purchase of copper stranded wire should start from the appearance. Generally, a good copper stranded wire has a bright appearance, obvious damage and scratches, and no obvious discoloration caused by oxidation reaction. The outer color is even, with black spots, cracks, and even distance

The grounding wire is an effective technical measure to ensure the safety of the operators, and it is the operator's amulet. Therefore, the quality of grounding wire plays an important role in ensuring personal safety, so the selected grounding wire should be multi strand soft bare copper stranded wire, and its section should meet the requirements of short circuit current, but not less than 25mm2. In order to be safe and reliable, the cross section should be increased to 35mm2, so that even if there are some broken strands, the requirement of 25mm2 can be met. According to the requirements for the installation position of the grounding wire, the grounding wire has the function of protecting the staff from sudden incoming calls from all parties at the work site. Therefore, the staff should always be at the ground wire

Flexible laminated insulated copper bus is also called sleeve insulating layer high flexible copper foil soft connection, which is developed from electrolytic grade copper sheet/foil with high conductivity. These are made by a pressure welding process in which a single copper bar is melted by applying direct current and pressure without foreign matter. When used, this product can help extend the service life of the product and reduce downtime. In addition, they also have good mechanical and electrical properties at high temperatures. The surface insulated dip coating cover has the flame retardancy of UL94v-0 standard, and can withstand high voltage and large current. Advantages of laminated flexible jumper: 1) Many laminations of welding press can improve conductivity and
