JLSZVK-3,6,10 series combination transformerDetailed product description：

JLSZVK-3、 6. The 10 series combination transformer is an outdoor dry-type transformer suitable for measuring voltage, current, electrical energy, and power in AC 10kV, 50 (60) Hz power systems.
JLSZVK-3、 6. The 10 series combination transformer adopts oil-free and maintenance free design, and has the advantages of high measurement accuracy, good insulation performance, anti-theft, and light weight.
JLSZVK-3、 6. The 10 series combination transformer consists of a voltage transformer and a current transformer connected through V/V wiring to form a three-phase device.

JLSZVK-3, Introduction to the Structure of 6,10 Series Combination Transformers
1. The primary and secondary coils of the current transformer are in a chain structure, and the measuring grade iron core is made of ultrafine crystalline alloy. The secondary wires are uniformly wound on the iron core. The primary coil is made of high-quality soft copper strip or glass wire enameled wire.
2. The iron core of the voltage transformer adopts a ring shape, with secondary winding and primary winding sleeved on the core column. The secondary winding is wound on an insulating cylinder, and the outermost layers of the first and last sections of the primary winding are equipped with electrostatic screens. Both windings are multi-layer cylindrical, with the primary winding wrapped around the secondary winding and insulation left between the windings.
3. The current and voltage transformers are installed and fixed on the component board inside the box, which is connected to the cover plate and can be lifted out of the oil tank for maintenance.
4. The secondary terminal is equipped with lead sealing screws to prevent electricity theft.
