3、 Use environment
The altitude shall not exceed 100om; Ambient temperature: - 25 ℃ ~ + 40 ℃;
◆ relative humidity: the daily average value shall not be greater than 95%, and the monthly average value shall not be greater than 90%;
◆ installation site; In places without fire, explosion hazard, conductive dust, chemical corrosive gas and violent vibration, if the above conditions are exceeded, the user can negotiate with our company.
4、 Functions and features
◆ high voltage switchgear, transformer and low voltage switchgear are Trinity, with strong completeness; ◆ perfect high and low voltage protection, safe and reliable operation and simple maintenance;
Less land occupation, less investment, short production cycle and convenient movement; ◆ flexible and diverse wiring schemes;
Unique structure: unique honeycomb structure, double-layer (composite plate) shell is firm, heat insulation, heat dissipation and ventilation, beautiful and high protection grade. The shell materials are stainless steel qin alloy, aluminum alloy, cold-rolled plate and color steel plate; ◆ various types: universal, villa, compact and other styles;
◆ the high-voltage ring network cabinet can be equipped with network automation terminal (FTU) to realize reliable detection of short circuit and single-phase grounding fault. It has the "four remote" function to facilitate the upgrading of distribution network automation.
