60mm High Voltage Cast Resin Ring Core Current Transformer for 35KV
LZCG series Cast Resin Straight-Through Current Transformer is suitable for current measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system.
New magnetic material is taken to be the core of the current
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.
