Summary

GDF series low-voltage fixed partition type switch cabinet is suitable for three-phase four wire system and three-phase five wire system with three-phase AC 50, 60Hz, rated voltage 60V and rated current 400A and below, which is used for receiving and distributing electric energy. It is widely used in power plants, substations, factories and high-rise Power Distribution Center PC and motor inspection bwcc.

Normal service conditions

Indoor use;

The altitude should not exceed 2000m;

The ambient height should not exceed + 40 ℃, and the average temperature within 24 hours should not be higher than + 35 ℃, and the ambient air temperature should not be lower than - 5 ℃.

Atmospheric conditions: safe and clean, the relative miscibility is not more than 50% when the temperature is + 40 ℃, and a relatively high relative humidity is allowed when the temperature is low, for example, 90% when the temperature is + 20 ℃. However, the influence of occasional condensation due to the change of temperature should be considered.

It should be installed in a place without severe vibration and impact, with seismic intensity ≤ 8 degrees, and installation inclination not exceeding 5 degrees.

The place without dust, corrosive gas or rain invasion.

Main technical parameters

Standard: GB7251 low voltage switchgear and control equipment;

Rated insulation voltage: AC660V;

Rated working voltage: 380V, 660V;

Rated frequency: 50-60Hz;

Rated current: horizontal bus system less than or equal to 5000A, vertical bus system 630A, 1250A, 1600A;

Rated timely withstand current: 100kA for horizontal bus and 100kA for vertical bus; rated peak withstand current: 175ka for horizontal bus and 110kA for vertical bus;

Function unit: the height of fixed partition type is 220mm, 440mm and 660mm,

Interchangeability: the pumping unit can be interchanged, and the fixed compartment cannot be interchanged.
