Feature

Accommodating more functional units in a smaller space, the C-profile with 25mm as the module can meet the requirements of various structural forms, protection levels and use environments.

They can be composed of standard units such as protection, operation, conversion, control, measurement, and indication, and can be assembled arbitrarily according to users' needs.

More than 200 types of assemblies can be used to form cabinet structures and drawer units in different schemes.

A large number of high-strength flame-retardant engineering plastic components are used to effectively strengthen the protective safety performance.

The main parameters have reached the current international technical level.

The three-in-one procedure can greatly reduce the site for storing and transporting prefabricated parts in the structure. No special complex tools are required.

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.
