SM6 medium voltage switchgear

Introduction
SM6 is an expandable module combination type, metal sealed switchgear series product, and the selected switch devices include
·Load switch
·Fluarc SF1,SFset
·Rollarc400 or 400D contactor
·Isolation switch
SM6 cabinet is used for users and distribution stations below 24 kV in secondary substations of industrial and mining enterprises. In addition, SM6 can ensure personal and equipment safety, and is easy to install and operate
SM6 cabinet is designed for indoor installation (IP4X), with actual dimensions of:
·375-750mm wide
·1600mm high
·1030 mm deep
Suitable for installation in distribution rooms or box type substations, the cables are wired from the front and all control functional components are centralized on the front control panel, simplifying operation. The cabinet can be equipped with accessories such as relays, coils, and instrument transformers
Normal working conditions
·Environmental temperature
·Not higher than 40 ℃
·The average temperature within 24 hours shall not exceed 35 ℃
·Not lower than -25 ℃
·Altitude
·Not exceeding 1000m
·If it is higher than 1000m, it is necessary to reduce the capacity for use (please consult our company)
·Direct sunlight
·Do not allow direct sunlight
·Environmental pollution
·No serious dust, smoke, corrosive substance pollution, flammable gas, steam or salt spray humidity
·Humidity
·The average relative humidity within 24 hours shall not exceed 95%
·The average relative humidity within one month is not higher than 90%
·The average vapor pressure within 24 hours shall not exceed 2.2kPa
·The average vapor pressure within one month shall not exceed 1.8kPa
Under these conditions, the likelihood of condensation occurring in the equipment is very low. If the humidity is high and the temperature changes dramatically, condensation may occur. In order to prevent insulation damage caused by high humidity and condensation, it is recommended to refer to the recommendations of Civil Engineering when designing buildings or houses and adopt appropriate ventilation facilities and devices
