Industrial plugs and sockets refer to power plugs and sockets used in industrial applications, usually installed on equipment or devices to provide power and signal transmission. With the continuous improvement of industrial automation and electrification, industrial plugs and sockets, as important power and control equipment, usually have stronger current carrying capacity, higher durability and reliability, can withstand harsh environmental conditions and working conditions, and have been widely used in various industrial occasions.
1. Specifications and characteristics of industrial plugs and sockets (1) Current types: 16A, 32A, 63A, 125A. (2) Protection level: generally divided into IP44, IP67 two, IP44: can prevent water spray from all directions and the hazard of solids above 1mm;IP67: Can prevent 1Flooding at a depth of 5 m (30 minutes of foaming time) and completely preventing the effects of dust hazards. (3) Color classification: according to the domestic conventional working voltage, it is divided into: 220V (blue) and 380V (red), in addition to 110V (yellow V (black) and other unconventional voltages through transformer or other forms. 
2. Specifications and characteristics of industrial plugs and sockets (1) Concealed straight sockets: generally installed in the equipment (chassis shell) with holes on the top of the shell, which can be installed in any position. If it is installed on the wall (it needs to be used with a bottom box), it is often used for power distribution of distribution boxes, distribution cabinets, injection molding machines, stage lighting, sound equipment, control systems and other equipment.
2) Concealed oblique socket: generally installed in the upper part of the equipment (chassis) shell and installed on the wall (need to be used with a bottom box), but it must maintain enough plugging space with the ground during installation, and is often used in equipment and scenes such as distribution boxes, steel smelting, petrochemical industry, and construction sites.
3) Surface-mounted socket: generally installed on the wall (ground), can not be equipped with a bottom box to use, but the installation must maintain enough plugging space with the ground, commonly used industries are: plant power distribution, computer room power distribution, exhibition hall, injection molding machine and other power transmission and distribution use. 
4) Connector: Generally used as a cable extension line, for air docking, and it is matched with plug concealed appliance input socket and surface-mounted appliance input socket. Commonly used industries are: distribution boxes, stage lighting and dark sound equipment, construction equipment, tunnel engineering and other aspects of power transmission and distribution. 
3. Specifications and characteristics of industrial plugs and sockets (1) Safe and reliable: first of all, the product color distinguishes the voltage, which is clear at a glance, easy to distinguish, and will not be mistaken;Secondly, the diameter, number of poles, and grounding contact positions of different specifications are different, and only the same specifications can be plugged to prevent misinsertionAgain, there is anti-electric shock protection, and the grounding electrode socket in the socket is longer than the phase pole and the middle line pole socket, so as to ensure that the plug is plugged in before the phase pole is connected, and the grounding pole is finally disconnected when it is pulled out, which is very safe to useFinally, such products also pay attention to safety in the selection and design of materials to improve the reliability of use.
2) Strong durability: industrial plug and socket products generally have good mechanical properties, with high strength, impact resistance, not afraid of falling or stepping on the characteristics;Heat-resistant, flame-resistant, its product shell shell and internal insulation parts have heat resistance, the temperature can reach (100 5), important parts can withstand (125 5);and flame retardant;Industrial plugs and sockets are generally more resistant to plugging and unplugging, and the temperature rise test of conductive contact parts (latches, sockets) does not exceed 50K, which is suitable for long-term use.
3) Strong versatility: the product adopts GB T 11918 11919-2001 standard, which is equivalent to IEC standard and fully in line with international standards. As a result, these products are used both nationally and internationally. At the same time, it has a wide variety of specifications and can meet various occasions and uses.
Beijing Tongwei Technology (TOWE) is a well-known brand in the field of electrical connection and protection in China, integrating design, research and development, production and manufacturing, with 23 years of industry experience, its IPS series of industrial plugs and sockets have advanced design, complete variety, good quality and excellent safety performance, from simple plugs to flexible design of the combination device by the user, can meet the various needs of users, can be widely used in IDC data center, industry, electric power, mining, airport, port, Petrochemical and other fields, well recognized by customers at home and abroad.
