10KV Medium Voltage Casting insullation current instrument transformer
The LZZW-10Q outdoor current instrument transformers are fully enclosed and cast in epoxy resin. Instrument transformer is equipped with one core and coil assembly rated for measurement and protection, and then output multi ratio. The current transformers are designed for electric power systems of 50Hz/60Hz rated frequency and 35kV rated voltage. They are used for outdoor mounting. The performances of the products meet standards IEC60044-1, IEC61869-2 and ANSI/IEEE C57.13. The products are applied to metering electric energy, voltage controlling and relay protection.
1. Measurement current & voltage for energy meter and power meter
2. Supply protection current signal for microcomputer protection relay set
New magnetic material is taken to be the core of the current instrument transformer, which has high magnetic permeability, low saturation magnetization and good stability. Therefore, the measuring accuracy is higher and the instrument security factor is lower. Since the high quality silicon processed by advanced technology is taken to be the core of the protection windings, which assured the accuracy limit factor is higher.
The semicircular ring core and secondary windings are vacuum poured by high quality epoxide resin in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance.Small size, light weight, small footprint, fixed in the ring network switchgear cable.The cable can cross the current transformer through its internal poles quickly and uniformly.
The Cast Resin Straight-Through Current Transformer can be divided several kinds according to the various current ratio, accuracy and rated loads. The specific parameters are showed in the corresponding to each model parameter tables.
High precision 0.2s
Designed for 30years lifes
Good Stability in 33kv power line
Multi ratio CT
Be sure to the type, current ratio, accuracy class, rated load and use of the products when you plan to make a order. Special specifications could be customized.All kinds of different specifications and parameters current transformers can be made according to your needs.
P1, P2 is primary polarity terminal, S1, S2 is secondary polarity terminal.
P2, S2 is homonymous terminals (subtractive polarity).
