Feature

The design allows for a compact space that accommodates multiple functional units, using C-type profiles with a modular dimension of 25mm to meet various structural forms, protection levels, and usage environments.

Standard units can be assembled for protection, operation, conversion, control, measurement, and indication, allowing users to freely choose and assemble based on their needs.

Over 200 types of assembly components can form different cabinet frame structures and drawer units.

High-strength, flame-retardant engineering plastic components are extensively used to enhance protective safety performance.

Main parameters meet current international technical standards.

Standardized procedures significantly compress the space required for storing and transporting prefabricated components.

Environmental conditions of use
1. The ambient air temperature is not higher than +40°C and not lower than -10°C. The average temperature over a 24h period does not exceed +35°C
2. The daily average relative humidity of the surrounding environment shall not exceed 95%, and the monthly average relative humidity shall not exceed 90%. The daily average water vapor pressure shall not exceed 2.2 kP, and the monthly average water vapor pressure shall not exceed 1.8 kP.
3. The altitude of the place of use shall not exceed 2000m.
4. The maximum seismic intensity does not exceed 8 degrees
5. The switch cabinet should be installed in an indoor place without fire, explosion hazard, serious pollution, chemical corrosive gas and violent vibration. Severe design under severe conditions meets the requirements of the class.
6. In areas with hot and humid temperature fluctuations, there will be the possibility of condensation in the switch cabinet, and the condensation controller and heater can be configured as needed to make the environment in the cabinet in an automatic control state to prevent the equipment from being damp and condensing.
7. If the user has special requirements, please negotiate with our company.
