Product Features
Notable system advantages with regard to design aspects:
Compact, space-saving design
Optimum protection for personnel and plant
Design verified by testing (type-tested)
High operational reliability and availability
Earthquake-, vibration- and shock-proof designs are available
Maintenance-free busbar and frame construction
Simple retrofitting procedures
•Compact design: more functional units can be accommodated in a smaller space.
•Strong structural versatility and flexible assembly. The C-shaped profile with 25mm as the modulus can meet the requirements of various structural forms, protection levels and use environments.
•Using standard modular design: standard units such as protection, operation, conversion, control, adjustment, measurement, and indication can be formed separately, and users can choose and assemble them according to their needs. With more than 200 kinds of assembly parts, it is possible to assemble cabinet frame structures of different schemes and form fixed partitions or drawer units.
•Safety: Daxing adopts high-strength flame-retardant engineering plastic components to effectively strengthen the protection and safety performance.
• High technical performance: the main parameters have reached the contemporary international level.
• Compressed site: High degree of three transformations, which can greatly compress the site for storing and transporting prefabricated parts.
• Convenient assembly: no special complex tools are required.
• The ambient air temperature is not higher than +40℃, not lower than -5℃, and the average temperature of 24h is not higher than +35℃;
• The surrounding air is clean, the relative humidity does not exceed 50% when the highest temperature is +40℃, and higher relative humidity is allowed at lower temperatures, such as 90% at +25℃, but the possibility of temperature changes should be considered May occasionally produce moderate condensation;
• For indoor use, the altitude does not exceed 2000m;
• In a place where there is no significant shaking or shock;
• Pollution degree: Level 3;
• Seismic intensity: level 8;
• The temperature of the switchgear during transportation and storage can range from -25°C to 55°C, and the temperature can reach +70°C in a short time (not more than 24h);
• If the above conditions of use cannot be met, it should be resolved by the user and the manufacturer through negotiation.
