In the cable industry, cable terminals are installed at the end of the cable line, which has certain insulation and sealing properties, so that the cable can be connected to other electrical equipment. And cable joints are installed between cables to connect cable conductors, forming a continuous circuit and having certain insulation and sealing properties. The main function of power cable accessories is to ensure the insulation and sealing of cable terminals and joints through the connection and splicing of cables. So it is widely used in the power system, and the types of products are also diverse.

（1） Classify the installation positions in the electrical cable line according to the attachment
1. Types of cable terminals
Cable terminals can be classified into the following categories based on their usage locations:
(1) Indoor terminal. A terminal that is neither exposed to direct sunlight nor exposed to harsh weather conditions.
(2) Outdoor terminal. Terminals used under direct sunlight or exposure to climate conditions, or both.
(3) Device terminal. The connected electrical equipment has corresponding structures or components connected to the cable To ensure that the connection between the cable conductor and the equipment is in a fully insulated state. For example, GIS terminals, elephant drop terminals for inserting transformers, and detachable connectors for medium voltage cables.
2. Types of cable intermediate joints
Cable intermediate joints can be divided into the following categories:
(1) Direct connector. An accessory that connects two cables to form a continuous circuit.
(2) Branch connector. Connect the branch cable to the accessory on the main cable.
(3) Transition joint. An intermediate joint that connects two different conductors or two different insulated cables.
