Product Description FL(R)N36-12(D) Load switches and
combiners (hereinafter referred to as "load switches" and
"combiners") are suitable for three-phase ac power systems of 10kV
and 50HzThis product as industrial and mining enterprises,
high-rise buildings, residential quarters, pre-installed type
substation, for the breaking, closing load current, the fault
current, control and protection circuit and the power distribution
transformer1.normal operating conditionsa)Ambient air temperature
is not more than 40 ºC, and at 24 h closed to the average no more
than 35 ºC. Minimum ambient air temperature 25 ºC.b)The effects of
sunlight can be ignoredc)No more than 3000m above sea
level.d)Ambient air is not significantly contaminated by dust,
smoke, corrosive and/or flammable gases, vapors, or salt fog. If
the user does not have special requirements, the manufacturer may
consider that these situations do not exist.e)The humidity
conditions are as follows:--The average relative humidity measured
within 24h is no more than 95%.--The mean value of water vapor
pressure measured within 24h shall not exceed 2.2kPa.--The average
monthly relative humidity should not exceed 90%.--The average
monthly water vapor pressure does not exceed 1.8kpa. In such
conditions appear condensation occasionally.f) The vibration or
ground motion from the outside of the switching equipment and the
control equipment has no obvious relationship with the normal
operation mode of the equipment. If the user has no special
requirements, the manufacturer may not consider these situations.GB
