Muenzaniso uye Zvinorehwa
Shandisa Environmental Conditions
a.Altitude: hapana kupfuura 1000m
b.Ambient tembiricha: -15 ℃～+40 ℃, tembiricha yemazuva ese haipfuure +35 ℃
c.Kunyorova kwezvakatipoteredza: avhareji yemazuva ese hunyoro hunyoro: ≤95% pamwedzi avhareji hunyoro hwehukama: ≤90%
Zuva nezuva avhareji yehutsi hwekumanikidza: ≤2.2x10-3 MPa Mwedzi wega wega avhareji yemhepo yekumanikidza: ≤1.8x10-3MPa
d.Kudengenyeka kwepasi: kwete kupfuura 8 madhigirii
e.Nzvimbo yekushandiswa: Mhepo yepakati haina kusvibiswa neguruva, utsi, zvinoparadza uye/kana magasi anobvira, mhute kana mhute yemunyu.
Ongorora: Kana iyo chaiyo yekushandisa nharaunda isingasangane nemamiriro ari pamusoro, ndapota bvunza nekambani yedu.
