Copper nose is a series of products often used in the power industry. It is commonly used for the connection of cable ends. This operation will make the cable ends electrically connected. High security and firmer. Of course, in addition to being used in the cable industry, these products are deeply loved, including construction, power equipment, household appliances, distribution cabinets and other industries.

Inductance: inductance is a property of closed circuit, that is, when the current passing through the closed circuit changes, electromotive force will appear to resist the change of current. This inductance (called self inductance) is the property of the closed loop itself. Assuming that the current of one closed loop changes and the electromotive force is generated in another closed loop due to induction, this inductance is called mutual inductance.

The use of wire nose can ensure sufficient contact area at both ends of the connection. Because the connecting part between the wire nose and the wire should be compacted with hydraulic pliers. The connecting section between the line nose and the equipment shall be compressed with bolts to ensure that the contact surface has sufficient actual contact diversion points under the restriction of pressure, so as to ensure that the contact surface will not be heated due to the small contact surface.

The copper pipe nose is generally made of T2 red copper and brass. The appearance of the product is a round head of a pot shovel. The top side is a fixed screw edge and the end is a stripped copper core of wires and cables. The varieties are divided into oil blocking type and pipe pressure type. The oil blocking type is better. In order to resist air oxidation, there is tin plating, that is, a layer of tin is plated on the surface of the copper ear to prevent oxidation and blackening, The copper wire lug shall be used only for wires larger than 10 square meters, and the cold pressed wire nose shall be used instead of the copper wire lug for wires smaller than 10 square meters. Copper wire lug can be divided into surface tinned and non tinned tube pressure type and oil plugging type. DT copper tinned terminal is to coat a layer of “tin” on the surface layer on the basis of the original DT copper terminal to enhance the conductivity of DT copper terminal.

When using copper noses, we should first make corresponding judgment and selection for different production sites. When using areas and spaces for these different products, we need to better select and apply different types of copper noses of different materials, Only through the use of such a product can we operate more effectively in the process of use. The copper nose has a lot of application scope in our current use, We need to have a certain understanding before use, so that we can effectively play its own relevant role in use, and we can use such products more and more effectively.

What is the function of thread nose?
1. Increase strength;
2. It is convenient to fix;
3. Increase the contact surface;
4. It is to prevent wire ends from flying and prevent electrical accidents.
What is a string nose?
Wire nose is a popular name, which is called wiring terminal in electricity. It is used to make joints for wires or cables to connect two or more wires or cables. Generally, thicker wires or cables will be used.

Why use a wire nose when wiring?
1. The wiring is convenient. There is no wire nose. Only solder wiring is available. It is troublesome and not too firm
2. It’s safe. The thread ends are pressed together without burrs
3. The design of the wire nose ensures sufficient contact area and will not lead electricity to flow through and cause accidents due to large heating
