What are the differences between different types of industrial plugs and sockets?
With the acceleration of industrial automation and electrification, industrial plugs and sockets are important components of power transmission. Different types of industrial plugs and sockets have significant differences in voltage, current, protection level and usage scenarios, providing users with a variety of choices.
Industrial plugs and sockets are divided into various models according to voltage and current. Common models include 16A, 32A, 63A, 125A, etc., which are suitable for low-power devices and high-power devices respectively. High-current models are usually used in large machinery, industrial production lines and other scenarios, while low-current models are suitable for small equipment or temporary power supply needs.
The protection level of industrial plugs and sockets is one of its important parameters.IP67 industrial sockets are designed for industrial environments and can withstand high currents and frequent plugging and unplugging. They are suitable for various industrial equipment such as machine tools and production lines. The housing is made of high-strength material with good impact resistance and corrosion resistance.R-212 industrial rubber socket is made of rubber material with excellent waterproof, dustproof and corrosion resistance. Designed for outdoor or humid environment to ensure the stability and safety of power supply.
Different types of industrial plugs and sockets also have differences in structural design. Three-pole plugs are suitable for single-phase power supply, four-pole plugs are suitable for three-phase power supply and are often used in medium-sized machinery and equipment. Five-pole plugs are suitable for three-phase four-wire power supply and are mostly used in high-power equipment or scenarios where a neutral line is required. In addition, some models are also equipped with a grounding terminal to enhance safety.
In short, the diversification of industrial plug and socket models not only reflects the advancement of technology, but also provides users with more flexible and safer power solutions. When choosing, users should fully understand the characteristics of different models and choose the appropriate model.
