▸ Product Introduction

Product overview

40.5kV switchgear series is a power supply equipment designed and developed by our company to meet the needs of the development of modern medium-voltage equipment. It absorbs the essence of similar products at home and abroad and is innovative. It is suitable for 50Hz AC network with rated voltage of 40.5KV. It is specially designed for the 35kV system of photovoltaic, wind power, energy storage and PCS booster. It can be used for wall-mounted installation in the tower of wind power generation, and can also be used as an independent electrical unit in the 40.5kV power system or box-type substation. The structure of this product is scientific and reasonable, and the switch spring operating mechanism is developed by our company, with simple and reliable action.

Environmental conditions of use

●The altitude is below 1000 meters;

●The upper limit of ambient air temperature is 50°C and the lower limit is-25 C.. The average daily temperature does not exceed 45°C;

●Relative humidity: the daily average is not more than 95%, and the monthly average is not more than 90%;

●The surrounding air is not obviously polluted by dust, smoke, corrosive or combustible gas, steam or salt spray;

●The amplitude of electromagnetic interference induced in the secondary system shall not exceed 1.6kV;

●The earthquake intensity shall not exceed 7 degrees and the inclination shall not exceed 5 degrees.

Note: The above are the operating environment conditions of the switch with conventional configuration. Please contact our company if you need to operate in the environment (such as high altitude, thick salt fog, hot and cold).
