3 TECHNICAL CHARACTERISTICS AND ADVANTAGES

Best surface protection

3.1.1 German environment-friendly and high-voltage electrostatic spraying automatic equipment is adopted

3.1.2 The vitrified membrane is formed on the surface of the spraying workpiece, and the surface coating of the product is uniform and attractive in color;

3.1.3 The membrane thickness after one-time spraying is 60μm〜80μm, and the precision error of coating thickness is ±20μm;

3.1.4 The spraying adhesion meets the national-level 0 standard, which can meet the 168h salt spray test;

Reliable electrical connection scheme

3.2.1 The miniature circuit breaker is connected by the customized busbar, to meet the requirements of temperature rise and electrical clearance;

3.2.2 The whole system is connected by national standard cable conductor, which is reliable;

3.2.3 The copper bar is processed by digital numerical control equipment with high processing accuracy, which effectively prevents the unreliable contact caused by the installation stress of the copper bar;

3.2.4 The advanced cold pressing terminal equipment ensures the reliable connection between the conductor and the components;

7+5 comprehensive test standards

Design verification according to IEC61439-1

4  Environmental Conditions for Use

4.1 The ambient air temperature shall not be higher than +40°C and not lower than – 25°C,and the average temperature within 24h shall not be higher than +35°C. Otherwise, the capacity shall be reduced according to the actual situation;

4.2 The altitude at the place of use shall not exceed 2,000m;

4.3 The relative ambient air humidity shall not exceed 50% when the maximum temperature is +40°C, and the high relative humidity is allowed at lower temperature (90% at +20°C).However, the change of temperature occasionally caused by the condensation shall be considered;

4.4 When the product is installed, the gradient with the vertical plane shall not exceed 5°;

4.5 The product shall be installed in a place without severe vibration and shock and that will not cause corrosion to the electrical components. The problem can be resolved through consultation with the manufacturer in case that users have special requirements.
