Low Voltage Switchgear
01
Low Voltage Cable Branch Box DFX
Features
● Compact design meeting creepage distance requirements, with exquisite appearance, small size, light weight, and easy installation.
● High insulation resistance and power frequency dielectric strength, ensuring high safety as an electrical enclosure—preferred for grid renovation.
● Excellent corrosion resistance against dilute acids, alkalis, salts, various oils, organic solvents, and seawater.
● Strong anti-aging performance with a service life of over 30 years.
● Good impact resistance and machinability, difficult to damage.
● No grounding required for the insulated case, saving installation labor and costs.
● Equipped with special insulating supports inside and a dedicated lock on the door (with a second padlock provided).
Operating conditions
● Ambient Temperature: -35°C to +45°C, with a 24-hour average temperature difference ≤35°C.
● Altitude: ≤2000m.
● Relative Humidity: ≤50% at +45°C; higher humidity is permitted at lower temperatures (e.g., 80% at +22°C), with consideration for occasional condensation due to temperature variations.
● Installation Site: Free from severe vibration, shock, and corrosive conditions that may damage electrical components.
Note: For applications exceeding the above conditions, please consult our company for customization.
