1. Safe and reliable
(1) This kind of product uses the shell color to express the rated voltage, if blue represents 220V, red represents 380V, at a glance, it is easy to distinguish, can not make a mistake.
(2) The diameter, number of poles, and position of ground contacts of different specifications are different. Only the same specifications can be inserted to prevent mis-insertion.
(3) Protection against electric shock. The grounding pole plug in the socket is longer than the phase pole and the neutral pole plug sleeve, which ensures that the plug is connected before the phase pole is connected and the grounding pole is finally detached when the plug is plugged in, and the use is very safe.
(4) High degree of protection. There are IP44 anti-splash type, IP67 anti-soaked type and so on. Not only can the human body not touch live parts, it can also be used under different environmental conditions to ensure safety.
(5) The elastic sleeve is added on the plug sleeve. Ensure that the plug is tightly contacted, well-conducted, and has a longer service life.
(6) There is a holding device, so that plugs and sockets are clamped after being inserted to prevent them from falling off, and the reliability is greatly improved.
(7) There is a cable clamp device that can clamp the cable sheath so that the fixed wood can be pulled off and used safely.

2. Durable
(1) Good mechanical properties. The product shell is made of high-quality engineering plastics, which has high strength, impact resistance, and is not afraid to drop or step on. The rubber and plastic used have anti-aging properties and can be used not only indoors, but also outdoors, for durability.
(2) Heat and flame resistance. The housing and the internal insulation components are heat-resistant, the temperature can reach (100±5)°C, and the important parts can withstand (125±5)°C; and they are fire-retardant.
(3) more resistant to use plug. For products with a rated current of 16A, the number of normal plugging cycles is more than 5,000.
(4) The temperature rise test of the conductive contact parts (plugs, plugs) does not exceed 50K and is suitable for long-term use.

3. Versatility
Products using GB/T 11918 ~ 11919-2001 standard, it is equivalent to IEC 60309-1, 2 standards, completely in line with international standards. Therefore, such products are common at home and abroad. At the same time, its variety of specifications can meet a variety of occasions and uses.

These characteristics of Industrial Plugs And Sockets make it highly safe and reliable and internationally versatile. Therefore, it has gradually received attention in the country. Through more than ten years of continuous promotion and application, industrial plugs and sockets have entered all walks of life, such as electricity, construction, port terminals, machinery industry and modern large-scale construction. The manufacturers have also evolved from the initial few to the current dozens. At the same time, with the development of science and technology, industrial plugs and sockets continue to innovate, a variety of rapid installation technology has been applied to the plug and socket, making it more convenient.
