Introduction of cable heads and cable accessories during cable installation
Wire and cable is a common and indispensable item in life. The correct installation of it is directly related to our future cable use and electricity safety. Therefore, in order to use electricity better and more safely, we need to install it correctly. cable. However, when you install the cable, have you noticed the two words "cable accessory" and "cable head", then, what are the cable accessory and cable head? What is the difference between them? Next, Ocean Cable will teach you how to distinguish between cable accessories and cable heads.
The difference between cable accessories and cable heads: the meaning is different.
Cable accessories, where accessories refer to components and materials, refer to products that connect cables to transmission and distribution lines and related power distribution devices. Generally refers to the intermediate connection and terminal connection of various cables in the cable line. Together with the cable, it forms a power transmission network. The terminal connection is divided into indoor terminals and outdoor terminals. Outdoor terminals refer to open-air cable joints, and indoor terminals refer to Indoor connection cables and electrical equipment joints, intermediate connections are divided into two types: straight-through type and insulated type.
The cable head is a device connected to the cable. It refers to the device that connects the cable and the cable to each other. It plays the role of smoothing the circuit, ensuring the insulation, sealing and mechanical protection of phases or phases; an additional word "cable terminal" should be mentioned here. "Connector" is a device that is installed at the end of a cable line to ensure the electrical connection of the power grid or other electrical equipment, and is provided as a device for insulating the conductive core of the cable.
The second difference between cable accessories and cable heads: different production methods.
Cables and cable accessories are all processed in the factory; and the forming of the cable heads is performed manually by the installer under the on-site conditions. The environmental conditions and the skill levels of the workers are different. Therefore, the quality of the molded cable heads will be different. different.
The difference between cable accessories and cable head three:
There are many types of cable accessories, and different types of cable accessories have their own characteristics. For example, heat-shrinkable cable accessories are made of rubber and plastic alloys with different components with "shape memory effect", which are made by heating and shrinking on the cable on site. The accessory has the characteristics of light weight, simple and convenient construction, reliable operation, low price, etc.; the prefabricated cable accessory is made of silicone rubber injection into different components, one-time vulcanization molding, only the contact interface is retained, and the cable is inserted during on-site construction. Accessories made...
No matter what kind of cable accessory, a complete product does not exist before installation, and the most complete cable accessory product is just a combination of certain components and materials. Only when these parts and materials are installed in the cable circuit according to the installation process requirements, there must be a section of cable in the complete cable accessory, which is the cable head.
Well, the above is the introduction of the difference between cable accessories and cable heads. I hope everyone can understand, and then install the cable correctly, play its due performance and protection, and serve us all.
