LZCK322-10 33KV Split Core MID Voltage Current Trasnformer
LZCK322-10 35KV Split Core MID Voltage Current Trasnformer applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV, and microcomputer protection. This type of current transformer employs imported silicon steel which with high permeability as magnetic material, have the characteristics of Small magnetic circuit loss and can be cut, its semicircular core and secondary windings employ high quality epoxy resin vacuum, casting in plastic-case which is flame retardance anti-moisture, stable performance, no maintenance.
Working conditions:
Ambient temperature: -35° C~+55° C, not exceeding +40° C.
The Height of above sea level: 0~ 3000m.
Atmosphere conditions: No highly polluted, errosion, erosiveness, radioactivity gases.
(continuous working under the rated current is allowed)
(P2 represents for primary polar end, S1, S2 represent for secondary polar end
P2 and S2 are subtractive polarity.
