Product Description:
Capacitor voltage transformer series products are suitable for current, electric energy measurement and relay protection in a system with effectively earthed neutral with rated voltage 35kV to 1000 kV and rated frequency 50Hz/60Hz. It can also be used for carrier wave communication concurrently.

Environment:
-60℃～+50℃

Features:
The capacitor voltage transformer own stable capacitor divider ratio, high precision and capacitance Deviation (-3% to +3%).
The optimum reactor design is perfectly matched with primary capacitance, and the transient response is fast.
The fast saturated damping device is used to suppress the ferromagnetic resonance in 10 cycles, which is superior to the IEC standard.
External expander, full sealed structure, internal micro positive pressure, avoid water intrusion, avoid pressure running.
The exposed metal parts are made of cast aluminum alloy, the antirust and anticorrosion performance is excellent, and the maintenance work is small in the later period.

Product
LVB(T) series current transformer is a kind of instrument transformer with oil-paper insulation, inverted structure. Its shell is made of cast aluminum alloy, with secondary coils inside. A conductive rod passes through the middle of the secondary coils. Insulating main insulation consists of a head and a straight rod insulation of two parts, by a straight part is composed of several capacitive screen equalizing sleeve. A stainless steel expander is on the top of product, can release the internal pressure. Most of connection between the shell and the flange and the base is to use sub-arc welding, instead of bolts and other mechanical connection, which enables reliable sealing performance, solve the problem of oil-immersed product oil leakage.

Environment:
-60℃～+50℃

Features:
The primary conductor is a penetrating structure, which meets the requirements of the system with large current, with good heat dissipation and low temperature rise, excellent dynamic and thermal stability, Series situation meet 63kA/3s (Rated short-time thermal current ) and 160kA(Rated dynamic current).
Argon arc welding structure is adopted in the upper and lower oil tank to prevent leakage. The exposed metal parts are made of cast aluminum alloy, the antirust and anticorrosion performance is excellent, and the maintenance work is small in the later period.

Application:
LVB (T) type current transformers can measure energy, metering, protection and transient protection in the power line.
