Feature

Flexible Cabinet Movement: The cabinet structure is modular, and the circuit breaker uses a removable trolley structure, making it easy to move out for maintenance.

Excellent Workmanship: The fully metal modular structure is made from imported galvanized steel plates with strong corrosion resistance, requiring no surface treatment. It is processed with high-precision CNC equipment and utilizes advanced multi-folding techniques, connected with rivet nuts and high-strength bolts, ensuring high precision, lightweight, and good strength.

Reasonable Structural Layout: The cabinet is divided into four functional sections: relay and instrument room, trolley room, cable room, and busbar room, separated by grounded metal partitions.

Simple Accessory Replacement: It is compatible with the ZN85-40.5 or VEM-40.5 new composite insulated vacuum circuit breakers and spring operating mechanisms, ensuring good interchangeability and easy replacement.

Excellent Performance: The switchgear employs an advanced composite insulation method along with new shielded bushings and contact boxes, providing reliable insulation and low failure rates.

Ample Space: The cable room has sufficient space to connect multiple cables.

High Standardization: The assembled switchgear ensures uniform dimensions and excellent quality.

Personalized Customization: The main wiring schemes exceed 160 types, allowing for flexible combinations to meet customer system configuration needs.

Safe and Reliable: The trolley frame is equipped with a screw nut push mechanism for easy movement and prevention of accidental damage. All operations are conducted with the cabinet doors closed. A comprehensive "five prevention" interlock feature includes mandatory mechanical locking between the main switch, trolley, and cabinet doors, preventing accidental operations and entry into live compartments.

Ingress Protection Grade: The enclosure has an IP4X rating, while the trolley room door in the open position has an IP2X rating.

Environmental Conditions
1. The ambient air temperature +40°C ~ -10°C. The average temperature over a 24h ≤ +35°C.
2. The daily average relative humidity of the surrounding environment ≤ 95%, monthly average relative humidity ≤ 90%. The daily average water vapor pressure ≤ 2.2 kP, and the monthly average water vapor pressure ≤ 1.8 kP.
3. The altitude of the place of use ≤ 2000m.
4. The maximum seismic intensity ≤ 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 large temperature fluctuations in humid and hot eyes, 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.
