In various cable accessories, the word plug often appears next to people's ears. It is a key link to connect single-phase or three-phase cables and high-voltage switchgear, transformers, cable distribution boxes and other electrical equipment. The cable plug is easy to operate. There are n front connectors and at least one rear connector in a group of plugs, all of which are T-shaped waterproof casing structures. The structure of the T-shaped waterproof casing mentioned here is a horizontal buried hole and a direct buried hole perpendicular to each other. One group is the horizontal direction of front joint, front joint, rear joint and rear joint. The front connector is equipped with crimping terminals and crimping terminals, and the horizontal buried holes of the front power plug and rear plug are connected to mechanical equipment. Plugs, front and rear, left and right live connections are all prefabricated components in the processing plant. The access line is smart, the volume is small, the structure is compact, the equipment process is simple, and the safety factor is high. It can be used in high-voltage switch cabinets, cable branch lines and other places, and is suitable for indoor or suburban equipment. There are many simple names for cable plugs, such as elbow joints, T-joints, detachable cable terminal equipment, etc. The application rated voltage is concentrated in three categories: 10KV, 20KV and 35KV, and the application models and specifications are divided into two categories: European classical and modern American. Generally applicable to ring network power switches, high-voltage cable support boxes, ring network cabinets and other incoming and outgoing line terminal equipment and high-voltage switch cabinets with waterproof casings, which can simplify the prefabricated components and heat-shrinkable professional skills of on-site equipment. In the development trend of cable accessories occupies a dominant position. With the rapid development of my country's economic and social development, the infrastructure construction of power companies continues to increase, various commercial and residential electricity consumption continues to expand, and the field of cable accessories is also booming. As the main member of cable accessories, the plug is very important and plays a vital role in the field of power transmission and transformation projects in my country and even in the world.
Elbow cable joints (referred to as elbows) are widely used in the connection of American box transformers, ring cabinets, cable branch boxes, buried transformers and other equipment. They are fully insulated and sealed plug-in terminals. Its rated current is 200A. Its conductive rod connection also has arc extinguishing function. Connected with a 200A bushing with an arc extinguishing device, it can be used as a load switch to operate a 200A current. The operation is extremely convenient. But the short-circuit current cannot be cut off.
European-style plugs are also called T-connectors, or elbow plugs, detachable cable terminals or prefabricated terminal heads. The European-style plug is used in the main network system of the cable distribution box or as the inlet and outlet cable joints of the ring network cabinet. It can be connected to 600A high-voltage bushings, multi-connected combined sockets, and can also be connected to 600A busbar bushings and rear T-type Connectors are combined to form multiple cable branches. The product has an electric test head. Rated current 600A, suitable for cable cross-section 25-400mm2, suitable for Φ40/Φ52/82.3/5/8″ sockets.
European-style rear-connected gapless zinc oxide arrester can be installed on electrical equipment such as box transformers, ring network cabinets, and cable branch boxes The front and back of the cable provide overvoltage protection for equipment or cables. The shielded rear surge arrester can provide reliable overvoltage protection for electrical equipment, and the molded outer shielding layer of the shielded rear surge arrester ensures the personal safety of installation and maintenance personnel The safe operation of the equipment, while its anti-ultraviolet, anti-aging, waterproof, moisture-proof, excellent performance ensures the reliable operation of the product in harsh environments.
