The copper-aluminum transition wire nose is very widely used in the industry. It is made of copper and aluminum, and it is cheaper than the copper nose in price. It is processed by friction welding, which is not easy to break and has strong electrical conductivity. Some cables cannot be wired directly with copper noses when connecting, so copper-aluminum terminals are needed to achieve transitional connection. Under normal circumstances, the copper nose is commonly used when connecting equipment such as copper wires or copper bars. If the connected cable aluminum core cable is connected to the copper bar, a copper-aluminum transition wire nose is required, which can improve the electrical reliability of the connection. , more secure to use. There are many types of copper-aluminum transition wire noses. When purchasing, you need to pay attention to the inner diameter of the barrel end (usually expressed in square numbers) and the inner diameter of the nose hole, so as to match the screws more appropriately. If these parameters are not very clear, you can judge the corresponding model according to the wire section of the wire. In addition, the copper-aluminum transition wire nose needs to be crimped with hydraulic pliers. After crimping, the firmness needs to be checked to avoid the problem of falling off due to unsuccessful crimping. 1. The double hole copper aluminum wire nose is welded and pressed from T2 red copper and L3 aluminum. The top is fixed with screws, and the end is placed on the stripped cable and pressed with terminal pliers. 2. Suggestions on the use of double hole copper aluminum wire nose: copper nose is recommended for wires larger than 10 square meters, and cold pressed wire nose is recommended for wires smaller than 10 square meters. 3. Scope of application: household appliances, electrical industry, mechanical equipment factory, shipyard, distribution cabinet, distribution box, etc.
