Heat Resistant Plastic Enclosures Manufacturers

The traditional instrument case is an aluminum alloy case, which is beautiful, light, and has certain protective functions. However, in recent years, waterproof cases have gradually replaced aluminum alloy boxes and become the main body of the production of instrument boxes.

1. The high temperature causes the service life of the electrical equipment of the distribution box to decrease The upper limit of the ambient temperature of the electrical equipment designed and manufactured according to the national standard should not exceed 40 °C, and the operating distribution box exposed to the hot sun in summer, because of the direct sunlight, the reflection of the heat on the cement floor and the equipment inside the box. The heat generated by itself, sometimes the temperature in the box exceeds 60 ℃. Such a high temperature can easily cause the insulation of electrical coils and leads to be aged and burn out; the electrical contacts will increase contact resistance due to the high temperature, which will cause the contacts to burn out; at the same time, the high temperature will also affect the electrical protection function. stability, reliability of action, and accuracy of measurement.

With the rapid development of science and technology in my country, the plastic technology is becoming more and more perfect. The plastic Waterproof Case has gradually replaced the metal waterproof case with its low cost, good insulation and high degree of waterproofness.

Aluminum equipment cases have shown wide application value in many fields due to their light weight, high strength, corrosion resistance and good processing performance.

1. When using the control box outdoors, the ambient temperature should not be higher than 40 degrees Celsius, the average temperature within 24 hours should not exceed 35 degrees Celsius, and the change limit of the outdoor ambient air temperature can only be reduced by 5 degrees Celsius. The temperature has a great influence on the use of the control box. Once the temperature is too high, it will affect the work of the equipment and even bring fire danger.

There is a general circuit distribution box for all users using electricity. It is called a distribution box. It has the characteristics of impact resistance and excellent insulation performance. Widely used in homes, high-rise buildings, residences, stations, ports, airports, shopping malls, cinemas, enterprises and other places.
