3Faas PAD-asennettava sähköasema
KEXR: n, Kiinan ammatillisen voimansiirto- ja jakelutoimittajan tuottama 3-vaiheinen PAD-asennettava sähköasema on kompakti ja modulaarinen voimalaite, joka sopii kaupunkitehon jakeluun, teollisuuspuistoihin, uuteen energiaan (aurinkosähkö/tuulivoima) ja muihin skenaarioihin. Perinteiseen sähköasemaan verrattuna se on pienempi ja joustavampi asentaa.

● Product overview
3phase pad-mounted substation is more flexible and convenient to use than civil substations, and is widely used in urban network reconstruction of high-rise buildings, residential quarters, industrial parks, commercial centers, airports, railway terminals, schools, a mining enterprise and other places.
● Functions and characteristics of YB-12 type 3phase pad-mounted substation
Pad-mounted substation high-voltage chamber is composed of high-voltage load switch, high-voltage fuse and lightning arrester, which can stop power transmission and prevent overload and short circuit at the same time; The low-voltage chamber is composed of low-voltage air switch, current transformer, ammeter and voltmeter. 3phase pad-mounted substation has advanced and reliable technology, and the boxes all adopt advanced processing technology, which has good corrosion resistance and wear resistance. It has the advantages of flexible combination, convenient transportation, installation and construction, low cost, no pollution and safe and reliable operation.
● Using conditions
◆ The altitude does not exceed 4000m
◆ Ambient temperature:-25℃-40℃
◆ Relative humidity: the daily average value is not more than 95%, and the monthly average value is not more than 90%
◆ Installation place: a place without fire, explosion danger, conductive dust, chemical corrosive gas and violent vibration.
Note：If the above conditions are exceeded, users can negotiate with KEXR
